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.
