Inspection - Simplicity 1691682 Service & Repair Manual

Inspection

GENERAL
1. Inspect all parts for damage, nicks or unusual wear
patterns. Replace all parts having unusual or exces-
sive wear or discoloration.
2. Inspect the sealing surfaces, bearing surfaces and
shaft splines. Polish the sealing areas on the shafts if
necessary. Replace any worn or damaged parts.
HOUSING ASSEMBLIES
1. Inspect both housing assemblies and bearings for
damage. Replacement of complete assembly will be
necessary if any damage is present.
2. Prior to reassembly, the lower housing must be thor-
oughly cleaned and old sealant must be removed.
FINAL DRIVE PINION ASSEMBLY
1. Inspect the teeth (internal and external) for damage
or unusual wear and replace as necessary.
2. Inspect the bearing surfaces of the shaft for damage
or unusual wear. If the shaft is found to need replac-
ing, the mating parts may also require replacement.
3. Inspect the washers for unusual wear.
Replacement of complete assemblies is recommended.
DIFFERENTIAL ASSEMBLY
1. Inspect the 60t gear teeth for damage or unusual
wear.
2. Inspect the 10t planet gears for damage or unusual
wear. Roll the gears to check for proper operation.
3. Inspect the axle bore in the 60t gear and the axle
bore in the end cap for unusual wear.
4. Check the bolts for proper torque of 25-32 ft. lbs..
5. If damage or unusual wear is found in any of the com-
ponents, replacement of the entire assembly is rec-
ommended.

REDUCTION GEAR/JACK SHAFT & BRAKE SHAFT
ASSEMBLY
1. Inspect the internal splines of the reduction gear and
the splines on the jack shaft for wear.
2. Inspect the bearing surfaces at the end of the jack
shaft for damage or unusual wear, if the shaft is found
to need replacing, the mating parts may also require
replacement.
3. Inspect the brake shaft bearings and the coupling for
damage or unusual wear and replace as necessary.
Note: The coupling is designed as a press fit onto the
shaft. Over time the splines may wear and the cou-
pling will become loose. If the coupling is not a
press fit onto the brake shaft, replacement is rec-
ommended.
4. Inspect the washers for unusual wear.
5. Replacement of complete assemblies is recommend-
ed.
INPUT SHAFT ASSEMBLY
1. Inspect each component for damage or unusual wear
and replace as necessary:
input shaft splines and gear teeth
input pinion
wave (spring) washer
bearing retainers
Reconditioning and Replacement of Parts

cleaned in a suitable solvent.
2. Clean and lightly lubricate parts prior to assembly
3. Replace all O-rings, gaskets and shaft seals.
4. Be sure to torque all threaded parts to the recom-
mended torque levels.
