3. Splines condition
Excessive deflection could cause vibration and
damage to drive shaft splines, impeller, flywheel
or floating ring (seal carrier depending upon the
model).
Place 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).
