C. Gear Box Reassembly
• Remove all rear bearings and set aside for cleaning. Clean all gears and the housings with a cleaning solvent.
(No. 111 Tri-chloralethylene)
NOTE
IT IS ESPECIALLY IMPORTANT THAT THE MATING SURFACES OF THE
HOUSINGS AND THE BEARING RACES BE PERFECTLY CLEAN, OTH-
ERWISE THE LOCTITE SEALANTS WILL NOT FORM AN EFFECTIVE
GASKET.
CAUTION
WITH THE CLUTCH ASSEMBLIES AND DRIVE GEAR ASSEMBLY,
WHERE THE FRONT BEARINGS REMAIN ATTACHED, IT IS IMPOR-
TANT THAT THE BEARINGS NOT BE IMMERSED IN THE SOLVENT.
THE SOLVENT COULD PENETRATE AROUND THE PLASTIC SEAL
AND DILUTE THE BEARING LUBRICANT.
• Using fixture No. 4675-0426-F-1, set front housing (the shallow housing) in place with the four small screw
holes to your left. Circled numbers in the drawing correspond to the 12 steps in reassembly.
NOTE
Once you have begun the reassembly do not leave it. Complete the reassembly
totally, otherwise the Loctite curing period may be thrown off.
1. Put new ″O″ rings (2275-0231) on idler shafts. Put a film of Loctite No. 290 on the mating surface of the
idler shafts and the facing of the holes where they fit, using a ″Q-tip″ type swab. Set 2 idler shafts (3375-
0669) in place and press down until ″O″ rings snap into place.
2. Put a film of Loctite No. 290 on the outer race of front drive shaft bearing and housing opening and set
drive assembly (4375-0132) into place.
CAUTION
Do not get Loctite No. 290 on inner surface of bearing races or it will freeze
up the races and prevent the bearings from turning properly.
3. Set fiber gear cluster assembly (4575-0285) in place over left hand idler shaft.
4. Put film of Loctite No. 290 on outer race of rear clutch assembly bearing and housing opening and set rear
clutch assembly (4375-0135) in place - minus cluster.
5. Put film of Loctite No. 290 on outer race of bearing on front clutch assembly and housing opening and set
