Disassembly - Simplicity LTH series Service Manual

Disassembly

1. Drain transaxle oil by removing the breather hose
assembly and positioning the transaxle so the
breather port is at lowest point of transaxle to allow
oil to drain thoroughly.
2. Remove the nut (A, Figure D–10) securing the brake
arm and remove the brake arm.
3.Position the transaxle upside down and secure it to the
bench to provide access to the twenty housing
assembly cap screws.
4. Remove the capscrews.
NOTE: Prior to October 27, 1993, a 3/16" drive internal
hex head cap screw was used. At the time, a change
was made to an "E-8" external drive "Torx" cap screw.
5. Separate the two housing halves by applying pres-
sure with two large straight blade screwdrivers. Use
caution to prevent damage to the mating sealing
surfaces as you separate the two halves.
NOTE: The sealant will make the two halves difficult to
separate.
6. Remove the bottom case half from transaxle. All
components should remain in the top case half.
CAUTION: The axle/differential assembly may stick as the
lower housing is being lifted off the upper housing.
7. Inspect the lower case half for damage. Inspect the
axle journal bearing pockets for excessive wear.
Inspect the brake rotor/stator pocket for excessive
wear.
NOTE: Prior to reassembly, the lower housing must be
thoroughly cleaned and all the old sealant must be
removed.
