IF ENGINE WON’T CRANK
ALWAYS CHECK FUSE FIRST
TEST #1
Using a remote starter
switch or a suitable
device, make a connection
between the large
terminals on the solenoid.
If engine does not
crank!!!
•Battery may be weak or
dead
•Starter may be bad
•Battery cables may have
bad connections
•Do not go to Test #2
until this test gives results.
TEST #2
If engine did crank in test #1,
disconnect green wire at spade
connector and apply positive
voltage from the battery to the
yellow wire with the orange
stripe. The positive voltage can
also be picked up on the
solenoid terminal where the
fuse connects. Make sure the
green and black wire with the
eyelet is well grounded. If
engine doesn’t crank now,
replace the solenoid.
Remember, all other tests are
useless unless these two tests
make the engine turn over.
TEST #3
If engine did crank in the first part of test #2,
reconnect green wire to solenoid. Using a jumper
wire attached to the positive terminal of the battery,
apply 12 volts to the red wire on terminal B
ignition switch. Try to crank, using the ignition
switch. If engine cranks, the fuse or the fuse holder,
or related wiring is defective somewhere back to the
solenoid.
TEST #4
If engine did not crank in test #3, this time move the
jumper wire attached to the positive terminal of the battery,
to the green wire on S
Ignition switch does have to be activated for this test. If
engine cranks now, ignition switch needs replacing.

ENGINE CRANKS BUT WON’T START
Checks for electrical problems
•While turning ignition switch to its first position, listen for the fuel solenoid on the
carburetor to click. It must click to supply fuel to the carburetor.
•Try a new spark plug.
•Check for spark at plug when it is removed and the threaded end is grounded.
•Unplug the six-position socket that connects engine wiring to mower wiring harness.
Engine will still crank. If plug doesn’t have a spark now, ignition module is probably
defective.
Checks for mechanical problems
•Make sure the tank gas valve is turned on.
•Remove air filter element to check for signs of gas in the throat of the carburetor.
•If no gas, check to see if choke is working properly.
•If all above checks show positive, carburetor must have an internal problem. Remove and
clean the carburet or.
ENGINE WIRING SYSTEM
Used on the RTB14544
Orange is not used in this applicatio n
Black wire comes from the ignition
switch and goes to the ignition module
to shut engine off.
Gray wire goes to the fuel solenoid.
Red wire comes from engine’s alternator through a
diode to convert the voltage from AC to DC. A simple
test to check its outpu t is to measur e the voltage of the
battery before the engine is started. Now start the
engine, the voltage should rise about 1 volt when the
engine starts. This voltage will slowly drop back to
normal voltage as the battery becomes fully charged.

DECK BELT ADJUSTMENT PROCEDURE
ALL VIEWS WITH ENGINE AND GUARDS REMOVED
For easier access to the belt
engagement system when
doing major repair, remove
the engine with it’s mount.
This bolt stops the travel of
the idler before it strikes
the engine pulley if the belt
gets worn too thin.
As the belt idler tightens
the the belt to start the
blades turning it also
removes the brake from
the blade spindle pulley.
Blade brake is activated
by the torsion spring
around the pivot bolt. It
is important that brake
stop the pulley on the
blade assembly when the
clutch is disengaged.
Stop for the tail of the
torsion spring.
To increase the the tension on the drive belt, adjust this nut
and the one on the other side of the bracket, counter
clockwise. Always check the operation of the blade brake
on the spindle pulley after the adjustment, since they are
both affected by the adjustment of the cable. The stopping
point has to be when the brake is no longer able to contact
the blade spindle when the engagement lever is released.
This is the point where engagement cable is connected
when a replacement needs to be installed.
Never tighten the nut against the loop on the end of the
spring at this bolt or at the other end as it connects to
the belt idler. The spring must always have room to
rotate on the bolt or it will break off at that point.
REPAIRING THE BLADE DRIVER ASSEMBLY
Pulley does not have a hub.
When removing, lift it off
like a washer, no gear
puller is needed.
Bearings are sealed. They can
be driven out and new ones
pressed in for repairing the
spindle assembly. It can also
be purchased as a unit for
easier repair.
Torque this nut to 120 ft/lbs
to keep blades from
tightening on the bolt during
use.
Torque top nut to 235
ft/lbs.Replacing this nut
each time it removed is
recommended.
Since there are no hubs on our
pulleys, this Belleville washer
is important to apply friction
between the nut and the
pulley to turn the shaft. Make
sure the outer lip is down to
best contact the pulley.
Spacer used to align the blade
pulley to the engine pulley.
Spacers are used between the
bearings to bear the torque
applied on the spindle bolt.
Washer is used to separate the
outer race of the bearing from
the stomp jumper.
Do not tighten against this
washer. The blades need to be
able to swing freely.
Insert the blade bolt through the blade and washer, then thread into the nut
welded on top of the stump jumper. Bring the bolt up snug to the blade then back it out
about half a turn. Tighten the locking nut on this bolt as it comes up above the welded nut
on the stump jumper. Torque this nut to 120 ft/lbs. If the nut is not secure enough, the bolt
will have a tendency to tighten on the blade and will eventually lock solid. It is imperative
that this blade swing freely on this bolt. When the blade locks up, the blade system gets out
of balance and the mower will shake violently and eventually break the deck around where
the spindle is mounted.
When doing major repairs on the under side of the deck, it might be easier
to tilt the deck on its front end. The only safe way to tilt an engine is with the spark plug
upward. That position allows the oil to go to the back of the crankcase and not forward past
the rings and into the combustion chamber. Also try to do the work while the gas is low in
the tank. Remove the hitch from the deck to make it easier to tilt the mower forward.
