REAR FINAL DRIVE ASSEMBLY
INSPECTION AFTER DISASSEMBLY
Drive Gear and Drive Pinion
lIf the gear teeth do not mesh or line-up correctly, determine the cause and adjust, repair, or replace as
necessary.
lIf the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new gears.
lDrive gear and drive pinion are supplied in matched sets only. Matching numbers on both drive pinion and
drive gear are etched for verification. If a new gear set is being used, verify the numbers of each drive pin-
ion and drive gear before proceeding with assembly.
Bearing
lIf bearings are chipped (by friction), pitted, worn, rusted, scratched, or unusual noise is coming from bear-
ing, replace with new bearing assembly (as a new set).
lBearing must be replaced with a new one whenever disassembled.
Differential Case Assembly
lIf the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new differ-
ential case assembly.
lIf the movement is not smooth when pushing cam ring of differential case assembly by hand, repair or
replace as necessary.
Differential Lock Solenoid
lIf the operating part of differential lock solenoid is not smooth, perform component inspection. Refer to
RFD-68, "
COMPONENT INSPECTION".
SELECTION ADJUSTING WASHERS
Drive Pinion Height Adjusting Washer
lDrive gear and drive pinion are supplied in matched sets only.
Matching numbers on both drive pinion and drive gear are
etched for verification. If a new hypoid gear set is being used,
verify the numbers of each drive pinion and drive gear before
proceeding with assembly.
lThe mounting distance from the center line of drive gear to the back face of drive pinion for the M226 final
drive is 109.5 mm (4.312 in).
On the button end of each drive pinion, there is etched a plus (+) number, a minus (-) number, or a zero
(0), which indicates the best running position for each particular hypoid gear set. This dimension is con-
trolled by a selective drive pinion height adjusting washer between drive pinion rear bearing inner race
and drive pinion.
For example: If a drive pinion is etched m+8 (+3), it would require 0.08 mm (0.003 in) less drive pinion
height adjusting washer than a drive pinion etched “0”. This means decreasing drive pinion height adjust-
ing washer thickness; increases the mounting distance of drive pinion to 109.6 mm (4.315 in). If a drive
pinion is etched m-8 (-3), it would require adding 0.08 mm (0.003 in) more to drive pinion height adjusting
washer than would be required if drive pinion were etched “0”. By adding 0.08 mm (0.003 in), the mount-
ing distance of drive pinion was decreased to 109.4 mm (4.309 in) which is just what a m-8 (-3) etching
indicated.
lTo change drive pinion adjustment, use different drive pinion height adjusting washer which come in differ-
ent thickness.
lUse the following tables as a guide for selecting the correct drive pinion height adjusting washer thickness
to add or subtract from the old drive pinion height adjusting washer.
