SERVICE POINTS OF REMOVALM25GEAI
3. REMOVAL OF PROPELLER SHAFT
(1) Make mating marks on the differential companion
flange and flange yoke.
CautionRemove the propeller shaft in a straight and level
manner so as to ensure that the boot is
notdamaged through pinching.
NOTEDamage to the boot can be avoided, and the work will
be easier, if a piece of cloth or similar material is
inserted in the boot.
(2) Use the special tool provided as a cover to prevent the
entry of foreign objects into the transfer.
4. REMOVAL OF SPACER
The number of spacers necessary may differ from one
location to another (front, rear, right, left). Record the
number of spacers used to ensure correct installation.
INSPECTIONM25GCAIl Check the sleeve yoke, center yoke and flange yoke for
wear, damage or cracks.
l Check the propeller shaft yokes for wear, damage or
cracks.
lCheck the propeller shaft for bends, twisting or damage.
l Measure the propeller shaft runout with a dial indicator.
Limit:
Front propeller shaft0.6 mm (.024 in.) or less
Center propeller shaft0.6 mm (.024 in.) or less
Rear propeller shaft0.6 mm (.024 in.) or less
NOTESet the V-blocks as much as possible to the end of the
shaft. Measure deflection at the center of the shaft.
