CHAPTER 1: INTRODUCTION

Professional Shop Manual intent

This Manual is intended to provide service dealers with an introduction to the electrical and mechanical aspects
of the 2000 series tractor.
• Detailed service information about the engine will be provided by the engine manufacturer.
Disclaimer: The information contained in this manual is correct at the time of writing. Both the product and the infor­mation about the product are subject to change without notice.
About the text format:
NOTE: is used to point out information that is relevant to the pro cedure, bu t doe s not fit as a step in the pr oce­dure.
• Bullet points: indicate sub-steps or points.

Disclaimer: This manual is intended for use by trained, professional technicians.
• Common sense in operation and safety is assumed.
• In no event shall MTD or Cub Cadet be liable for poor text interpretation or poor execution of the proce­dures described in the text.
• If the person using this manual is uncomfortable with any procedures they encounter, they should seek the help of a qualified technician or Cub Cadet Technical Support.

Fasteners

Caution is used to point out potential danger to the technician, operator, bystanders, or sur­rounding property.
Warning indicates a potentially hazardous situation that, if not avoi ded, could result in death of serious injury.
Danger indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. This signal word is to be limited to the most extreme situations
• Most of the fasteners used on these mowers are sized in fractional in ches. The eng ine and tran smissions are metric. For this reason, wrench sizes are frequently identified in the text, and measur ements are given in U.S. and metric scales.
• If a fastener has a locking feature that has worn, replace the fastener or apply a small amount of releas­able thread locking compound such as Loctite® 242 (blue).
• Some fasteners like cotter pins are single-use items that are not to be reused. Other fasteners such as lock washers, retaining rings, and internal cotter pins (hairpin clips) may be reused if they do not show signs of wear or damage. This manual leaves that decision to the judgement of the technician.

! CAUTION! CAUTION
• Be prepared in case of emergency: Keep a fire extinguisher nearby Keep a first aid kit nearby Keep emergency contact numbers handy
• Replace any missing or damaged safety labels on shop equipment.
• Replace any missing or damaged safety labels on equipment being serviced.
• Grooming and attire:
! WARNING! WARNING
! CAUTION! CAUTION
Do not wear loose fitting clothing that may become entangled in equipment. Long hair should be secured to prevent entanglement in equipment.
Jewelry is best removed.
• Protective gear: includes, but is not limited to
Clear eye protection ................................ while working around any machinery
Protective gloves ..................................... where necessary

Chemically resistant gloves..................... when working with chemicals or solvents
Respirator................................................ when working with chemical or solvents
Appropriate tinted eye protection............. when cutting or welding
Flame resistant headgear, jacket, chaps. when cutting or welding
• Remember that some hazards have a cumulative effect. A single exposure may cause little or no harm, but continual or repeated exposure may cause very serious harm.
• Clean spills and fix obviously dangerous conditions as soon as they are noticed.
! DANGER! DANGER

• Lift and support heavy objects safely and securely.
• Be aware of your surroundings and potential hazards that are inherent to all power equipment. All the labels in the world cannot protect a technician from an instant of carelessness.
• Exhaust fumes from running engines contain carbon monoxide (CO). Carbon monoxide is a colorless odorless gas that is fatal if inhaled in sufficient quantity. Only run engines in well ventilated areas. If running engines indoors, use an exhaust evacuation system with adequate make-up air ventilated into the shop.
Introduction

Assembly

Torque specifications may be noted in the part of the text that covers assembly, they may also be summarized in tables along with special instructions regarding thread locking or lubrication. Whichever method is more appr o pr i at e will be used. In many cases, both will be used so that the manual is handy as a quick-reference guide as well as a step-by-step procedure guide that does not require the user to hunt for information.
The level of assembly instructions provided will be determined by the complexity and of reassembly, and by the potential for unsafe conditions to arise from mistakes made in assembly.
Some instructions may refer to other parts of the manual for subsidiary procedures. This avoids repeating the same procedure two or three times in the manual.

Brakes

CHAPTER 3: BRAKES

Brake adjustment

The transmission on the 2000 series tractor is driven by a Hydro-Gear BDU-10L pump. The pump will provide the braking action when it is in operation. There is a mechani cal brake on the side of the tran smission. This brake is used primarily as a parking brake. It is also used as a back up brake in cas e of a failure of the hydro pump.
The operation of the brakes should be tested before performing any adjustments.
To test the operation of the brakes:
1. Disengage the hydro pump by-pass rod by pulling it out and hooking it. See Figure 3.1.
2. Set the parking brake by depressing the brake pe da l and lifting-up on the parking brake lever.
3. Attempt to push the tractor. If it can be pushed by hand without skidding a rear wheel, check and adjust the brakes.
4. Release the parking brake.
By-pass rod
Outer latch plate
travel limit pin
5. Attempt to push the tractor again. If it cannot be pushed with reasonable effort, check the hydro pump by-pass and adjust the brakes.
Figure 3.1
Inner latch plate
6. Visually inspect the linkage to confirm that it functions properly.
• Beneath the floor panel, on the left side of the trac-
tor there are two semi-circular latch plates (bell cranks).
• The outer latch plate rotates with the drive control
pedals. The inner latch plate rotates with the clutch/brake pedal.
6a. With the clutch/brake pedal fully released:
• The travel limit pin should be resting against the
front of the curved slot. See Figure 3.2.
Figure 3.2
17
2000 Series Tractors
• The rod that connects the clutch/brake latch plate to the heavy brake actuator spring should not droop. See Figure 3.3.
• Check the brake pedal shaft bushings for wear.
Adjust the brakes by:
NOTE: The brake is located between the frame and
the transmission on the right side of the trac­tor. It is a tight fit, but it can be reached from the under side of the tractor aft, of the rear axle.
No droop
Figure 3.3
0.010” feeler gauge
NOTE: In Figure 3.4, the by-pass rod was removed
for a clearer view of the caliper.
1. Wiggle the brake rotor slightly, and attempt to insert a 0.010” (0.38mm) feeler gauge between the rotor and either pad.
NOTE: There is a fixed pad in the transaxle hous-
ing.

Brake puck/rotor replacement

On transmission used on the 2000 series tractor , the brake pucks are wearing p a rts that will need to be serviced from time to time. If the tractor is operated with the parking brake dragging, the pucks will wear out rapidly and the brake rotor will develop hot spots. If the tractor is operated long enough, the rotor may have grinding marks on it with excessively worn pucks.
! CA UTION! CA UTION
NOTE: The brake pucks and the rotors are serviced at the same time.
Screws
If the rotor shows hot spots or any other signs of damage, including warpage, it must be replaced. Failure to do so can result in the failure of the brakes
To remove/replace the brake pucks and rotor:
1. Lift and safely support the rear of the tractor.
2. Remove the transmission by following the proce­dures describe in Chapter 5: Drive.
3. Remove the two screws that secure the brake caliper to the right transmission housing using a 3/8” wrench. See Figure 3.5.
4. Lift the caliper off of the transmission.

of the front wheels:
• Worn rod ends
• Bent drag links
• Loose steering arms or loose drag links
• Worn axles or king pin bores
• Worn wheel bearings
• Lift the front axle and spin each front wheel to check for excessive run-out. NOTE: If there is run-out, find the midpoint of the run-out and use that point for your measurements.
• Repair as necessary before setting the toe angle.
NOTE: The front tires will have a “TOE-IN” between 1/16”
and 1/4” to allow the unit to track properly.

Electronic Power Steering

CHAPTER 6B: ELECTRONIC POWER STEERING

NOTE: The basic steering system, such as the tie rod ends, drag links axles, etc., are covered in Chapter 6A:
Steering.
In 2011, Cub Cadet introduced the Electronic Power Steering (EPS) system on the Cub GTX2154LE (50
versary edition) tractor. The EPS provides an electric assist to the steering wheel.
The EPS is a system consisting of three sub-assemblies: the rubber torsion coupling, the EPS module and the EPS motor & gearbox. They form an assembly that is inserted between the steering shaft and the steering hous­ing. The EPS system is treated as one part.
DO NOT loosen or separate any of

the EPS components. The module is calibrated to the tor-

EPS motor & gearbox

Rubber torsion coupling

Figure 6B.1
Rubber Torsion Coupling
The steering shaft connects the steer ing wheel to the EPS system through the rubber torsion coupling. As the steering wheel is turned, it applies force to the coupling. The force causes the torsion coupling to twist or torque. The amount the coupling torques is determined by the amount of force applied to the steering wheel, the more force applied to the steering wheel, the more the coupling twists.
NOTE: The rubber torsion coupling has hard stops bui lt into it. If the force applied to the steering wheel causes
the coupling to hit its hard stops, the steering input will transfer through the module into the steering gearbox. This allows manual steering if there is a failure of the EPS system.
EPS Module
The EPS module controls the power supplied to the EPS motor. It senses the amount of force that is being applied to the steering wheel by monitoring the torsion coupling. The module will ramp up the power supplied to the EPS motor as the force applied to the steering wheel increases. The EPS motor will reach full power within a couple of degrees of deflection of the torsion coupling.
NOTE: Auto steering is a condition were
the EPS will turn the wheels to one direction, once the engine is started. This happens because the calibration is off and the EPS thinks there is a steering input when there isn’t.
The EPS comes with a 4 year warranty. If there is a failure with the system, replace the entire sys­tem as an assembly.
81
2000 Series Tractors

EPS motor & gearbox

The steering input passes through the torsion co upling and module into the gearbox. The gearbox then passes the input force to the output shaft connected to the steer­ing housing.
EPS module
The EPS motor assists in turning the input shaft by driving a set of planetary gears. The planet ary gears drive a worm shaft. The worm shaft drives a worm gear on the output shaft.
IMPORTANT: DO NOT open or service the steering
gearbox.
DO NOT drop or hammer on any of

Troubleshooting the EPS

Electronic Power Steering
The first step in troubleshooting the EPS system is to understand how it works. See Figure 6B.4.
,JQLWLRQPRGXOH
*5281'
0$*1(72
%$77(5<
Figure 6B.4
When troubleshooting the EPS system, The technician needs to isolate the problem to either the EPS assembly
or the circuits that go to the EPS assembly.
NOTE: To protect the EPS module, it will turn off if the steering input is held at a hard stop for more than 2 sec-
onds. The EPS will turn back on once the input is released from the hard stop.
• A constant 12 volts is supplied by the battery through a 40 amp fuse in the fuse box.
• The EPS is grounded through the green wire.
• The EPS senses the ignition pulses from the igni­tion module primary windings throug h th e ye llow wire with a white trace.
• Once the EPS determines that the engine is run­ning (by sensing the ignition pulses from the igni­tion coil) it will turn on.
• The EPS will power the EPS motor as it senses input from the steering wheel.
NOTE: Before troubleshooting any electrical circuit on a tractor, always make sure the battery is fully charged. NOTE: The EPS assembly has constant battery power and is not controlled by the ignition switch.
To troubleshoot the EPS assembly:
1 Place the tractor on flat, level ground.
2. Remove any attachments that may be on the tractor.
3. Set the parking brake.

4. Turn the steering wheel so that the wheels are p oint­ing straight forward.
5. With the ignition key in the off position, open the hood.
6. Check the 40 amp fuse in the fuse box. See Figure 6B.5.
NOTE: If the fuse is blown, replace the fuse and check for
a short in the red wire that goes to the EPS assem­bly.

7. Locate, but do not disconnect the EPS harness con­nector behind the battery. See Figure 6B.6.
8. Check for battery voltage at the red wire: 8a. Set the Digital Multi Meter (DMM) to the DC
volts scale.
8b. Measure the battery voltage across the bat-
tery terminals
NOTE: If the battery voltage is < 12.6 volts, charge
the battery before continuing.
8c. Connect the black (-) lead of the DMM to the
negative post of the battery.
8d. Back probe EPS harness connector at the red
wire with a black trace, with the red (+) lead of the DMM.
NOTE: The DMM should read battery voltage.
9. Check the ground to the EPS: See Figure 6B.7. 9a. Set the DMM to the DC volts scale. 9b. Connect the red (+) lead to the positive post of
the battery.

9d. Place an amp clamp meter on the red wire
with a black trace. See Figure 6B.8.
NOTE: Cut the tape that seals the loom at the EPS
connector end of the harness and slide the loom off of the wires to attach the amp
clamp. 9e. Start the tractor. NOTE: The voltage reading on the DMM should
now read over 13 volts. If it does not, repair
the charging circuit before proceeding with
troubleshooting the EPS system.

NOTE: A sustained voltage over 25 volts will damage the EPS module. NOTE: If the results are within the specified ranges or if the amperage draw is higher then expected, check for
a mechanical bind by:
14. Remove the steering pinion gear by following the procedures described in Chapter 6A: Steering.
15. Re-check the steering. NOTE: If the steering now works, the pr oblem lies between the sector gear and the front wheels. A frozen axle
is a likely suspect.
16. Remove the EPS assembly. NOTE: When removing the EPS from the steering housing, it should slide out easily. If it does not, repair the
steering housing before condemning the EPS.
11. The oscilloscope should show a pulsed signal. The bottom or resting phase of each pulse must be below 5 volts. The peak of each pulse must be over 5 volts. See Figure 6B.9.
12. The pulses must be at 9 Hertz (cycles/second) or higher (engine needs to be >490 RPM).
13. If the resting phase of the pulse is above 5 volts, there is a short in the safety circuit of the tractor that is pulling up the voltage of the ignition module.
17. Check the steering shaft bushings. NOTE: If the steering shaft is binding in the bushings, replace the bushings before condemning the EPS.
18. If nothing is in a bind, replace the EPS assembly.

CHAPTER 7: ELECTRICAL SYSTEM

Introduction

This chapter is divided into four sections:
• Section 1: About this chapter and precautions
• Section 2: Components
• This section will describe the location and operation of the electrical components on the mower. Where appropriate, some disassembly or component removal instructions will be included.
• Section 3: Diagnostic Techniques
• This section will cover basic tools, techniques, and methodology for diagnosing electrical issues on the mower. A lot of the information in this section can be applied to other equipment.
• Section 4: Schematics
Before disconnecting any electrical component, take precautions to prevent the component or

the wires attached to it from shorting out. The mo st effective means of doing th is is to disconnect the battery ground cable from the negative battery terminal. Unless performing test s that require the electrical system to be in operation, disconnect the negative cable from the battery before doing any work to the electrical system of the mower.
Electrical System
Components
The 2000 series tractors have the same Cub Cadet Rev-Tek system used on the 1000 series tractors.

RMC Module

The RMC module contains elect ron ic logic circuits. When diagnosing anything that is connected to the RMC module, a high impedance test light or a high impedance digital multi-meter (DMM) must be used. The amperage draw of a standard incandescent test light may over-burden some internal electronic circuits, burning out the module.
NOTE: These tools are not outrageously expensive or exotic. High impedance test lights (Thexton model 125 is typical) can be purchased locally from stores like NAPA for under $30.00. Appropriate multi meters can be purchased for under $100.00, and are an invaluable tool for any competent technician.
• It is typical when industries shift from electromechanical to electronic controls that diagnosis shifts from tracing through a number of independent circuits to checking the in-puts to and out-puts from a central processor. This is similar to, but much less complex than the transition that the auto industry made with the conversion to fuel injection in the 1980s.
NOTE: The starter safety circuit has no connection to the RMC module.
• It is still important to be familiar with the workings of the individual component s of the electrical system, but some of them can now be checked from a central point on the mower. This makes life easier on the tech­nician, frequently making it unnecessary to connect to difficult to reach switches in the preliminary stages of diagnosis.
• The function of individual safety switches can be seen as providing information “inputs” to the RMC mod­ule.
• The next part of this section gives a detailed description of the electrical components on this mower, their function in the system, and their physical location on the mower. Armed with this information and the proper tools, a technician should be able to efficiently diagnose most electrical problems.

Key switch

The Key Switch is similar to those used in a variety of MTD applications since 1999. The differ ence , in this case, is that it is incorporated in the same housing as the RMC module. The two items are not available separately. See Figure 7.1.
1. In the “OFF” position, continuity can be found
between the M, G, and A1 terminals. See Figure 7.2.
• M is connected to the magneto by a yellow wire, G is connected to ground by a green wire, and A1 is connected to the afterfire solenoid.
NOTE: In the “OFF” position, the magneto primary windings are grounded, disabling the ignition sys­tem. The afterfire solenoid loses its power from the B terminal. This turns off the fuel supply.
NOTE: The A1 terminal is shorted to ground when the key is moved to the “OFF” position. This is a legacy fea­ture from older tractors that had the afterfire solenoid pow ered directly from the alternator. This feature in not needed on current production tractors.

• Symptom: loud “BANG” when key is turned to the OFF position: The afterfire solenoid is not closing, either because it is physically damaged or the power is not being turned off. Check for power at the solenoid. Check continuity between G and A1 terminals. Check for no con­tinuity between A1 and the B terminals.
NOTE: If the engine is at an idle when the key is turned off, fuel is drawn into the engine through the idle ports of the carburetor by-passing the fuel shut off solenoid. The raw fuel will travel through the engine and ignite in the muffler causing an afterfire.
• Symptom: Engine runs 3-5 seconds after key is turned to OFF position: The afterfire solenoid is turning off the fuel supply, but the ignition is continuing to operate. Check continuity between the M and G terminals in the OFF position. Check continuity from yellow wire connection all the way to the spade terminal on the magneto.
2. In the START position, continuity can be found between B, S, and A1 terminals.
• Battery power from the B terminal is directed to the start circuit through the S terminal and to the afterfire solenoid through A1.
• Symptom: No crank and no starter solenoid click solenoid. Test for a fully charged battery, then check for power where the fused red wire with white trace connects to the B terminal. Check for continuity between B and S terminals in START position. If power is getting to the S terminal in the START position, the problem lies down-stream in the starter circuit. Check continuity from the orange wire on the S terminal to the orange wire with white trace on the trigger spade on the starter solenoid. If it is broken, trace through the brake and PTO switches.
