WORKSHOP MANUAL
Winget Mechanically Fed Mixers
Models: 200TM
From 1998
Refer to the Drum Adjustment illustration. The Adjusting Plate holding the rear of the
Bevel Pinion Housing
(D) is slotted to allow the Housing to move up and down
enabling correct adjustment of the chain tension (F) . Check and adjust the Chain
Tension and tighten the bolts holding the Adjusting Plate. By adding or subtracting
shims
(E) between the thick packer and the Bevel Pinion Housing ensure the
housing is horizontal in the Trunnion and square to the rear plate. Re-check the
Chain Tension and fully tighten the bolts and setscrews securing the Bevel Pinion
Housing
(D) , knock over the Tab Washers.
Crank the engine ensuring both the countershaft and bevel pinion turn freely. Coat
the bevel pinion with open gear lubricant and fit the pinion guard. Fit the rear chain
guard.
Following the procedures described earlier refit the Bevel Gear Guard and Drum
Assembly.
Countershaft, Trunnion Journal and Driven Chainwheel/ ‘V’ Pulley
Although it is recommended that the trunnion is removed completely from the mixer
should the countershaft or trunnion journal require attention it is possible to leave the
trunnion assembly in place provided it is properly supported.
Remove the engine housing lid, top plate, engine housing chain guard and infill plate.
Slacken the two bolts through the bevel pinion housing adjusting plate and the two
setscrews which secure the casting at the pinion end to release the tension on the
countershaft chain.
Disconnect the split links retaining both the engine drive and countershaft chains and
remove the chains. On electric drive mixers the drive is transmitted to the
countershaft by means of a ‘V’ belt in place of the chain.
Withdraw the gib head key retaining the driven chainwheel/’V’ belt pulley to the
countershaft and pull off the chainwheel/pulley.
Lock the drum in the vertical position using the handwheel locking plunger and using
suitable lifting equipment, jacks or chocks secure the trunnion to prevent it moving
when the journal is withdrawn.
Remove the two setscrews retaining the journal casting to the mainframe, take the
weight off the trunnion and withdraw the journal from the trunnion.
Support the assembly in a soft jawed vice, remove the circlip retaining the
countershaft sprocket and pull off the sprocket, remove the feather key.
Remove the circlip in front of the bearing and using a soft faced hammer and suitable
drift knock the shaft out of the journal from the opposite end.
