Introduction
This manual is designed to provide information necessary to service and repair the Fuller® Transmissions listed on the front.
The service procedures have been divided into two sections: In-Vehicle Service Procedures and Transmission Overhaul Procedures—Bench Service. In-Vehicle Service Procedures contain procedures that can be performed while the Transmission is still installed in the vehicle. Transmission Overhaul Procedures contain procedures that are performed after the Transmission has been removed from the vehicle.
The procedure sections are laid out with a general heading at the top outside edge of each page followed by more specific headings and the procedures. To find the information you need in these sections, first go to the section that contains the procedure you need. Then look at the heading at the top and outside edge of each page until you find the one that contains the procedure you need.
Transmission Overhaul Procedures follow the general steps for complete disassembly and then assembly of the Transmission.
Note: In some instances the Transmission appearance may be different from the illustrations, but the procedure is the same.
It is assumed in the detailed assembly instructions that the lubricant has been drained from the Transmission, the necessary linkage and vehicle Air Lines disconnected and the Transmission has been removed from vehicle Chassis. Removal of the Gear Shift Lever Housing Assembly (or Remote Control Assembly) is included in the detailed instructions (How to Remove the Gear Shift Lever). This Assembly MUST be detached from the Shift Bar Housing before the Transmission can be removed.
Follow closely each procedure in the detailed instructions, make use of the text, illustrations, and photographs provided.
Assemblies
•When disassembling the various Assemblies, such as the Mainshaft, Countershafts, and Shift Bar Housing, lay all parts on a clean bench in the same sequence as removed. This procedure will simplify assembly and reduce the possibility of losing parts.
Bearings
•Carefully wash and lubricate all usable bearings as removed and protectively wrap until ready for use. Remove bearings planned to be reused with pullers designed for this purpose.
Cleanliness
•Provide a clean place to work. It is important that no dirt or foreign material enters the unit during repairs. Dirt is an abrasive and can damage bearings. It is always a good practice to clean the outside of the unit before starting the planned disassembly.
Input Shaft
•The Input Shaft can be removed from the Transmission without removing the Countershafts, Mainshaft, or Main Drive Gear. Special procedures are required and provided in this manual.
Information General
1
Introduction
Snap Rings
•Remove Snap Rings with pliers designed for this purpose. Snap rings removed in this manner can be reused, if they are not sprung or loose.
When Using Tools to Move Parts
•Always apply force to Shafts, Housings, etc., with restraint. Movement of some parts is restricted. Never apply force to driven parts after they stop solidly. The use of soft Hammers, Soft Bars, and Mauls for all disassembly work is recommended.
Before assembling the Transmission, check each part carefully for abnormal or excessive wear and damage to determine reuse or replacement. When replacement is necessary, use only genuine Fuller® Transmission parts to assure continued performance and extended life from your unit.
Since the cost of a new part is generally a small fraction of the total cost of downtime and labor, avoid reusing a questionable part which could lead to additional repairs and expense soon after assembly. To aid in determining the reuse or replacement of any Transmission part, consideration should also be given to the unit's history, mileage, application, etc.
Recommended inspection procedures are provided in the following checklist:
Bearings
•Wash all Bearings in clean solvent. Check Balls, Rollers, and Raceways for pitting, discoloration, and spalled areas. Replace Bearings that are pitted, discolored, spalled, or damaged during disassembly.
•Lubricate Bearings that are not pitted, discolored, or spalled and check for axial and radial clearances.
•Replace bearings with excessive clearances.
•Check bearing fit. Bearing Inner Races should be tight to Shaft; Outer Races slightly tight to slightly loose in Case Bore. If the Bearing spins freely in the Bore the Case should be replaced.
Bearing Covers
•Check Covers for wear from thrust of adjacent Bearing. Replace Covers damaged from thrust of Bearing Outer Race.
•Check Cover Bores for wear. Replace those worn or oversized.
Clutch Release Parts
•Check Clutch Release parts. Replace Yokes worn at Cam surfaces and Bearing Carrier worn at Contact Pads.
•Check Pedal Shafts. Replace those worn at Bushing surfaces.
Gears
•Check gear teeth for frosting and pitting. Frosting of gear teeth faces presents no threat of Transmission failure. Often in continued operation of the unit, frosted gears "heal" and do not progress to the pitting stage. In most cases, gears with light to moderate pitted teeth have considerable gear life remaining and can be reused, but gears in the advanced stage of pitting should be replaced.
•Check for gears with Clutching teeth abnormally worn, tapered, or reduced in length from clashing during shifting. Replace gears found in any of these conditions.
•Check Axial Clearance of gears.
2
Introduction
Gear Shift Lever Housing Assembly
•Check spring tension on Shift Lever. Replace Tension Spring if lever moves too freely.
•If Housing is disassembled, check Gear Shift Lever bottom end and Shift Finger Assembly for wear. Replace both gears if excessively worn.
Gray Iron Parts
•Check all gray iron parts for cracks and breaks. Replace parts found to be damaged.
Oil Return Threads and Seals
•Check oil return threads on the Input Shaft. If return action of threads has been destroyed, replace the Input Shaft.
•Check Oil Seal in Rear Bearing Cover. If sealing action of lip has been destroyed, replace Seal.
O-Rings
•Check all O-Rings for cracks or distortion. Replace if worn.
Reverse Idler Gear Assemblies
•Check for excessive wear from action of Roller Bearings.
Shift Bar Housing Assembly
•Check for wear on Shift Yokes and Block at pads and lever slot. Replace excessively worn parts.
•Check Yokes for correct alignment. Replace sprung Yokes.
•Check lock screw in Yoke and Blocks. Tighten and rewire those found loose.
•If Housing has been disassembled, check Neutral Notches of Shift Bars for wear from Interlock Balls.
Sliding Clutches
•Check all Shift Yokes and Yoke slots in Sliding Clutches for extreme wear or discoloration from heat.
•Check engaging teeth of Sliding Clutches for partial engagement pattern.
Splines
•Check Splines on all shafts for abnormal wear. If Sliding Clutch gears, Companion Flange, or Clutch Hub has wear marks in the Spline sides, replace the specific shaft effected.
Synchronizer Assembly
•Check Synchronizer for burrs, uneven and excessive wear at contact surface, and metal particles.
•Check Blocker Pins for excessive wear or looseness.
•Check Synchronizer contact surfaces on the Synchronizer cups for wear.
Washers
•Check surfaces of all washers. Washers scored or reduced in thickness should be replaced.
Information General
3
Introduction
Make sure that Case interiors and Housings are clean. It is important that dirt and other foreign materials are kept out of the Transmission during assembly. Dirt is an abrasive and can damage polished surfaces of Bearings and Washers. Use certain precautions, as listed below, during assembly.
Axial Clearances
•Maintain original Axial Clearances of 0.006–0.015 in. for Mainshaft Gears.
Bearings
•Use a Flange-End Bearing Driver for bearing installation. These special drivers apply equal force to both Bearing Races, preventing damage to Balls/Rollers and Races while maintaining correct Bearing alignment with Bore and Shaft. Avoid using a Tubular or Sleeve-Type Driver, whenever possible, as force is applied to only one of the Bearing Races.
Cap Screws
•To prevent oil leakage and loosening, use Fuller® Sealant #71205 on all Cap Screws.
Gaskets
•Use new Gaskets throughout the Transmission as it is being rebuilt. Make sure all Gaskets are installed. An omission of any Gasket can result in oil leakage or misalignment of Bearing Covers.
Initial Lubrication
•Coat all Limit Washers and Shaft Splines with Lubricant during assembly to prevent scoring and galling of such parts.
O-Rings
•Lubricate all O-Rings with silicon lubricant.
Universal Joint Companion Flange or Yoke
•Pull the Companion Flange or Yoke tightly into place with the Output Shaft Nut, using 650–700 lb-ft (881.28–949.07 N•m) of torque. Make sure the Speedometer Drive Gear or a Replacement Spacer of the same width has been installed. Failure to pull the Companion Flange or Yoke tightly into place can result in damage to the Mainshaft Rear Bearing.
IMPORTANT
See the appropriate Illustrated Parts Lists (specified by model series) to ensure that proper parts are used during assembly of the Transmission.
4
Model Designations
Transmission model designation and other Transmission identification information are stamped on the Transmission Tag. To identify the Transmission model designation and Serial Number, locate the Tag on the Transmission and then locate the numbers as shown.
When calling for service assistance or parts, have the Model and Serial Numbers handy.
Do not remove or destroy the Transmission Identification Tag.

Lubrication Pumps
Three types of Lubrication Pumps are available for use on this Transmission and are described below:
Internal: An internal Lubrication Pump is located in the lower front of the Transmission and is driven off the Upper Countershaft. 13-Speed Transmissions rated 1550 lb-ft and above include the Internal Pump standard. All 18-Speed Transmissions contain the Internal Lube Pump.
Auxiliary Countershaft: An Auxiliary Countershaft Pump is mounted on the rear of the Transmission and driven off the Auxiliary Countershaft.
PTO Driven: A PTO driven pump is externally mounted on the 6 or 8 bolt PTO openings and driven off the PTO Gear.
Power Take Off (PTO) Usage
PTOs can be mounted in the following way:
6 or 8 Bolt: The 6 or 8 bolt openings are standard with the Transmission. The PTO is mounted to the opening and driven from the PTO Gear on the Front Countershaft.
Thru-Shaft: The Thru-Shaft PTO mounts on the rear of the Transmission. It requires a special Auxiliary Housing and Main Case Countershaft with Internal Splines.

Lubrication
IMPORTANT
Transmission Filters should be changed during regular lube intervals. Inspection of the Transmission Filter should be conducted during preventive maintenance checks for damage or corrosion. Replace as necessary.
•For a list of Eaton® Approved Synthetic Lubricants, see TCMT0021 or call 1-800-826-HELP (4357).
•The use of lubricants not meeting these requirements will affect warranty coverage.
•Additives and friction modifiers must not be introduced. Never mix engine oils and gear oils in the same Transmission.
If the Transmission operating angle is more than 12 degrees, improper lubrication will occur. The operating angle is the Transmission mounting angle in the Chassis plus the percent of upgrade (expressed in degrees). For operating angles over 12 degrees, the Transmission must be equipped with an Oil Pump or Cooler kit to insure proper lubrication.
The Transmission must not be operated consistently at temperatures above 250 °F. Operation at temperatures above 250 °F [121 °C] causes loaded gear tooth temperatures to exceed 350 °F [177 °C] which will ultimately destroy the heat treatment of the gears. If the elevated temperature is associated with an unusual operating condition that will reoccur, a Cooler should be added, or the capacity of the existing cooling system increased.
The following conditions in any combination can cause operating temperatures of over 250 °F [121 °C]:
•Operating consistently at slow speed.
•High ambient temperatures.
•Restricted air flow around Transmission.
•Use of engine retarder.
•High horsepower operation.
Note: Transmission Coolers must be used to reduce the operating temperatures when the above conditions are encountered.

Preventive Maintenance
Everyday there are countless vehicles operating over the highways with Transmissions in such a neglected mechanical condition, they can be referred to as failures looking for a place to break down. They lack a proper and organized preventive
maintenance program.
Preventive maintenance is a general term which applies to all procedures necessary to have maximum life and satisfactory service at the lowest possible cost, short of removing and repairing the unit.
A number of conditions contrary to good preventive maintenance can generally be pointed to when inspecting a failed Transmission. Taking a few minutes every so many hours or miles to do a few simple checks could help avoid eventual breakdown or reduce the repair cost. If the Transmission is not cared for, it will breakdown.
Note: Transmission appearance may differ, however the procedure is the same.

Step 1
1.Clean suspected oil weep area with a clean dry cloth or mild soluble degreaser.
2.Ensure lube is to proper level.
3.Notify the customer that it is only a weep and it is not considered to be detrimental
to the life of the transmission.
4.Repair is complete.
1.Do not repair: Rear seal is designed to allow minimal seepage.
2.Ensure lube is to proper level.
1.Determine the origin of the leak path.
2.If origin of leak is obvious skip to Step 3.
3.If the origin of the oil leak is not obvious then use either of the two following steps to determine the oil leak:
Note: Do not use a high pressure spray washer to clean the area. Use of a high pressure spray may force contamination into the area of concern and temporarily disrupt the leak path.
i.Clean area with a clean dry cloth or mild soluble degreaser and fill the transmission to the proper lube level.
OR
ii.Clean the area as noted above and insert tracer dye into the transmission lube and fill transmission to proper lube level.
Step 2
Operate vehicle to normal transmission operating temperature and inspect the area for oil leak(s) visually or if tracer dye was introduced use an UVL
(Ultraviolet Light) to detect the tracer dye’s point of origin.
Note: When inspecting for the origin of the leak(s) make sure the assumed leak area is not being contaminated by a source either forward or above the identified area such as the engine, shift tower, shift bar housing, top mounted oil cooler, etc...
Step 3
Once the origin of the leak is identified, repair the oil leak using proper repair procedures from the designated model service manual.
Step 4
After the repair is completed, verify the leak is repaired and operate the vehicle to normal transmission operating temperature. Inspect repaired area to ensure oil leak has been eliminated. If the leak(s) still occurs, repeat steps or contact the Roadranger Call Center
at 1-800-826-4357.

Power Flow
An understanding of the engine's Power Flow through a Transmission in each particular gear will assist the Technician in troubleshooting and servicing a Transmission.
The Fuller® Transmission can be thought of as two separate “Transmissions” combined into one unit. The first “Transmission” or Front Section contains six Gear Sets which are shifted with the Gear Shift Lever. The second “Transmission” called the Auxiliary Section, contains three Gear Sets and is shifted with air pressure.
Note: This Transmission is referred to as a Constant Mesh Type Transmission. When in operation, all gears are turning even though only some of them are transferring power.

Power Flow
Note: The heavy lines in the figure below outline the Power Flow description. For help in understanding the Transmission components, refer to the figure “Transmission Components” on the previous page.
1.Power (torque) from the vehicle's engine is transferred to the Transmission's Input Shaft.
2.The Input Shaft rotates the Main Drive Gear through internal Splines in the hub of the Gear.
3.The Main Drive Gear meshes with both Countershaft driven gears and the torque is split between both Countershafts.
4.Because the Countershaft Gears are in constant mesh with the Mainshaft Gears, all the Front Section gearing rotates. However, only the engaged or selected Mainshaft Gear will have torque. External Clutching teeth on the Sliding Clutch will engage internal Clutching teeth on the selected Mainshaft Gear. Torque will now be provided from both opposing Countershaft Gears, into the engaged Mainshaft Gear, and through the Sliding Clutch to the Front Section Mainshaft.
5.The rear of the Front Section Mainshaft is splined into the Auxiliary Splitter Clutch and torque is now delivered to the Auxiliary Splitter Clutch.

Power Flow
In direct gear, the Front Sliding Clutch is moved forward and engages into the back of the Main Drive Gear. Torque will flow from the Input Shaft to the Main Drive Gear, Main Drive Gear to Sliding Clutch, Sliding Clutch straight into the Front Section Mainshaft which delivers the torque to the Auxiliary Splitter Clutch. See figure below.
Note: All Countershaft and Mainshaft Gears will rotate, but the gears will not be loaded.

Torque will flow from the Countershafts to the Reverse Idler Gears. Torque will then flow from the Reverse Idler Gears to the Mainshaft Reverse Gear. Torque will now travel through the Mainshaft Reverse Gear, the Sliding Clutch in the Reverse position and then to the Mainshaft and Auxiliary Splitter Clutch. See figures below.
Note: The Idler Gears cause the reversal of rotation.

Power Flow
Depending on the position of the Splitter Button (L or H) the Auxiliary Splitter Clutch engages in either the Auxiliary Drive Gear or the Splitter Gear. The selected Auxiliary Gear transfers torque to both Auxiliary Countershafts.
If the Auxiliary Section is in low range, the Range Sliding Clutch is rearward and engaged into the Auxiliary Mainshaft Reduction Gear. Torque flows from the Auxiliary Countershafts, into the Auxiliary Mainshaft Reduction Gear, through the Range Sliding Clutch and then into the Output Shaft (Auxiliary Mainshaft).

Power Flow
Auxiliary Section Power FlowHigh Range
If the Auxiliary Section is in high range, the Range Sliding Clutch is forward and engaged into the back of the Auxiliary Drive Gear. Torque flows through the Auxiliary Section in high range depending on the splitter state selected (L or H). If splitter (L) is selected, torque flows from the Auxiliary Splitter Clutch to the Auxiliary Drive Gear. From the Auxiliary Drive Gear, torque flows to both Countershafts and then to the Splitter Gear. Torque then flows into the Range Sliding Clutch and Output Shaft. (See Figure 1st-13 Speed; 1st-Low Split-18 Speed).
If splitter (H) is selected, torque flows directly through the Auxiliary Section. Torque flows from the Auxiliary Splitter Clutch to the Auxiliary Reduction Gear to the Range Sliding Clutch to the Output Shaft. The Auxiliary gearing still turns, but the gear teeth will not be loaded. (See Figure 1st-High Split-18 Speed).
