Clamp the housing in a soft jawed vice and remove the gib head key retaining the
bevel pinion and pull off the bevel pinion.
Remove the circlip from the groove within the housing and using a soft faced
hammer knock the shaft and bearings out of the housing. The bearings can now be
removed from the shaft.
Carefully remove the seals from the bearings and pack the bearings with good quality
grease, refit the seals, do not completely fill the bearings with grease leave some
room for expansion as the grease warms up in service.
To reassemble secure the bevel pinion shaft into a soft jawed vice. Using the correct
size of Bearing tube and a soft faced hammer or suitable drift fit the bearings to the
shaft. Note the larger of the two bearings is fitted to the longer shank of the shaft.
Remove the shaft from the vice and using the vice support the bevel pinion housing.
Using the correct size of bearing tube or suitable drift and the soft faced hammer
knock the shaft fully into the housing. Fit the retaining circlip into the groove within
the housing. Check the shaft turns freely.
Assemble the bevel pinion to the shaft, fitting the gib head key. The pinion is fitted to
the longer shank of the shaft. If correctly assembled the threaded holes in the
casting will be at the same end. Do not at this stage fit the sprocket to the opposite
end of the bevel pinion assembly, as this will prevent re-assembly of the housing
back into the trunnion.
Loosely fit the triangular adjusting plate back into the trunnion, locating the plate on
the peg. Fit the two bolts through the adjusting plate from the rear of the trunnion so
that when assembled the head of the bolts will be sandwiched between the trunnion
rear plate and the bevel pinion shaft drive sprocket.
Work the bevel pinion housing back into the trunnion and through the adjusting plate.
As the shaft protrudes through the rear of the trunnion slide on the sprocket until it is
fully home.
Refit the setscrews, tabwashers, packer and shim set retaining the bevel pinion
housing and finger tighten only.
Fit the gib head key retaining the drive sprocket and refit the drive chain, when
connecting the split link the open end of the link should be fitted so that it points away
from the normal direction of rotation which is anti-clockwise when looking directly at
the chain.
Release the trunnion and turn back to its lowest position.
