1. Surface condition
2. Groove condition
3. Splines condition
Excessive deflection could cause vibration and
damage to drive shaft splines, impeller, flywheel
or seal carrier.
Place rear drive shaft on V-blocks and set-up a dial
gauge in center of shaft. Slowly rotate shaft; dif-
ference between highest and lowest dial gauge
reading is deflection. Refer to the following illus-
tration.
Maximum permissible deflection is 0.5 mm
(.020 in).

Check condition of couplers.
Replace front drive shaft if necessary.
Damper
Visually inspect shape of damper no. 24 for defor-

damage or evidence of wear, replace it.
To verify the preload of the boot no. 7, proceed as
follows:
NOTE: To verify the boot preload and free length,
