Turn the handwheel and check the drum and trunnion operate correctly and contact
the travel stops without unduly stressing the tilting chain.
Tilting Chain
To access the tilting chain remove the upper and lower chain guards behind the front
plate of the trunnion. The chain is anchored to the trunnion end plate by means of
two split links one in each end of the chain.
To replace the chain, place the drum in the vertical position and engage the
handwheel locking plunger in the lower single hole. Slacken the four setscrews
retaining the tilting bracket and lift the bracket in the slots to release any tension on
the chain, tighten at least one of the setscrews to hold the bracket in place. Separate
the split links and unhook the chain. Reverse the procedure to refit the chain
adjusting the final chain tension by sliding the tilting bracket in the slots. Refit the
guards and check the trunnion contacts the travel stops without unduly stressing the
chain.
Countershaft/Bevel Pinion Drive Chain.
Remove the chain guard from the rear of the trunnion. Crank the engine over until the
chain split link is visible. Disconnect the split link, hook the new chain loosely onto the
split link slowly crank the engine and pull the new chain in place round the
countershaft sprocket. Remove the old chain and link. Loop the new chain round
the sprocket in the bevel pinion shaft and fit the new split link. The open end of the
split end should point away from the normal direction of rotation, which is anti-
clockwise when looking directly at the chain. Check and adjust the chain tension.
(See Bevel Pinion Shaft and Housing). Refit the chain guard.
Bevel Pinion Shaft and Housing
Follow the procedures described earlier and remove the drum, bevel gear guard and
disconnect the countershaft bevel pinion drive chain.
Rotate the trunnion until it reaches its highest point and lock in place. Remove the
gib head key securing the sprocket to the bevel pinion shaft. Remove the bevel
pinion guard, release the tabwashers and remove the setscrews, packers and shims
securing the bevel pinion housing. At this point the bevel pinion housing should be
supported by a second pair of hands, strapped or supported in some other manner to
prevent it dropping down sharply and causing damage to the casting, it will otherwise
only be secured by the loose fitting retaining plate and sprocket.
Remove the nuts and washer off the two bolts retaining the bevel pinion housing
adjusting plate. Using a soft faced hammer knock the bevel pinion shaft through the
sprocket until it is possible to remove the sprocket. Remove the bolts through the
retaining plate and lift the bevel pinion housing out of the trunnion.
