Set the motor vertically and install the
spacer in the center before of the
cylinder block.
An alternate method of installing this
bearing is to use the bearing puller bar
and press the bearing onto the shaft
with the center screw of the puller bar. A
spacer must be used between the center
screw and the bearing.The bearing must
be pressed on until it rests on the
shoulder of the shaft to insure adequate
bearing clearance.
To check the shaft end play, assemble the
shaft and bearings housing, end cap and
gasket (see pages 23, 24, 19 and 18).The
F000 148
shaft end play should be from 0.08 to
35
0.18 mm [0.003 - 0.007 in] for frame sizes
033 - 089 and from 0.15 to 0.3 mm [0.006
- 0.012 in] for frame sizes 119 - 334. If
adjustment is necessary, a shim can be
placed under the bearing race in the end
cap.
