Wear
Visually inspect shape of dampers for deforma-
tion or other damage. Ensure they are firmly re-
tained.
Inspect carbon ring and its contact surface. Check
for scoring, pitting, chipping or other evidence of
wear.
With a finger nail, feel contact surfaces of bearing
and seals. If any irregular surface is found, renew
drive shaft.
1. Carbon ring contact surface
2. Splines condition
3. Seal contact surface
Deflection
Excessive deflection could cause vibration and
damage to drive shaft splines, impeller, flywheel
or seal carrier.
Install drive shaft in V-blocks and set a dial gauge
in center of shaft. Slowly rotate shaft
; difference
between highest and lowest dial gauge reading is
deflection. Refer to the following illustration.
Maximum permissible deflection is 0.5 mm (.020
in).
