MAINTENANCE
Main Jackshaft Bearing replacement.
IMPORTANT
The Bearing Shims must be replaced exactly as
removed, if the Jackshaft Bearings are removed.
Fig.38
If the Jackshaft Bearings are replaced, the Jackshafts
alignment must be checked and re-set.
The shafts are aligned, fore and aft, with Shims behind the
bearings, and vertically with slotted holes in the bearing
flanges.
Assemble the Shafts, Sheaves and Bearings with
Lock Collars, and Shims in place as removed.
Tighten the Bearing Bolts, and with a Straight
Edge across the front of the Shafts, check the ‘fore
and aft’ alignment.
Add or remove Shims as necessary.
Place the Straight Edge on top of the Shafts.
Back-off the Bearing Bolts and adjust the Bearings
‘up or down’ to align the shafts.
