Remove the bearings and clean all the components. Carefully remove the seals from
the new 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.
Reverse the procedure to re-assemble using a suitable bearing tube or drift to seat
the front bearing into the housing, retain with the circlip. Pass the countershaft (end
with feather key way and circlip groove) through the housing and into the bearing and
knock fully home using a soft faced mallet or hammer. Fit the second bearing over
the shaft and knock fully home using a bearing tube or drift until it contacts the
shoulder on the shaft.
Fit the feather key, slide on the small sprocket and retain with the circlip. Smear a
little grease around the circumference of the trunnion/journal bearing face and in the
bore of the corresponding bearing boss on the trunnion. Slide the journal fully home
into the end of the trunnion and retain using the two setscrews. Remove the chocks,
lifting equipment or jacks and tighten the setscrews fully.
Coat the end of the countershaft with anti-seize compound and slide on the
chainwheel/’V’ belt pulley, pushing fully onto the shaft, fit the gib head key.
Refit both the countershaft chain and the engine chain/’V’ belt, ensuring that the open
end of the split links point away from the normal direction of rotation.
Adjust the countershaft chain tension (refer to the ‘drum adjustment illustration’ and
‘bevel pinion housing’) and tighten the bevel pinion housing, check the engine drive
chain tension or ‘V’ belt pulley tension, adjust the tension as necessary. On diesel
engines adjust the shimming below the engine (see ‘engines’), on electric drive
machines move the motor either upwards or downwards on the threaded adjusters
as required. (see 415v motors)
Fit the infill plate, chain guards and plastic plug, top plate and engine-housing lid.
Release the locking plunger and operate the handwheel ensure the trunnion tilts
correctly, start the engine and check the operation of the drum drive, also check for
unusual noises.
Front Trunnion Bearing Replacement
Lock the drum and trunnion in the vertical position using the handwheel locking
plunger. Using suitable lifting equipment, jacks or chocks support the trunnion just
behind the front leg of the mainframe.
Remove the two nuts and washers securing the profiled retaining plate, take the
weight of the trunnion and pull off the plate and bearing boss. Clean all parts.
Reverse the procedure to refit, not forgetting the grease nipple which also prevents
the bearing from turning. Remove the chocks, jacks or lifting equipment.
