Winget Mechanically Fed Mixers
Models: 200TM
From 1998
The shafts appear identical but the hopper cradle shaft has a longer un-machined
centre section.
To remove, fully lower the hopper, stop the engine/motor and release any residual
hydraulic pressure. Remove the hopper and upper ram pivot pin as described
previously.
Attach suitable lifting equipment to the hopper cradle and take the weight, remove
the four locking nuts and weigher links from both shafts on each side of the cradle.
Once the links are removed the cradle will be free and can safely placed on a
suitable surface.
Slide the shaft out of the inserts in the mainframe taking care not to lose the washers.
The inserts are retained via the capscrews which pass through the mainframe and
enter indents in the side of each insert, remove the inserts and using a suitable
bearing tube knock out the needle bearings and seals.
Reverse the procedure to fit new bearings and seals, the lips on the seals should
face outwards, before refitting the inserts into the mainframe and over the shaft
lubricate the needle bearings with grease and smear the outer diameter of the inserts
with anti-seize compound.
Place the shaft through the mainframe and push on the special washers, one each
end, slide the inserts onto each end of the shaft and push home into the mainframe
aligning the indents in the inserts with the threaded holes in the mainframe. Refit the
capscrews to prevent the inserts rotating.
Note the capscrews in the mainframe are of a different length to those in the hopper
cradle, take care that the capscrews do not bottom on the needle rollers otherwise
the shafts will be prevented from turning and the batchweigher will read inaccurately.
Repeat the operation on the hopper cradle shaft.
Coat the inserts with anti-seize compound and push the inserts home into the cradle
and over the shaft. Align the indent in the collars with the threaded holes into the
cradle securing the inserts in place using the capscrews and washers. Take care that
the capscrews do not bottom onto the needle rollers causing damage. Turn both
shafts within the needle bearings, the shafts should turn relatively freely.
Using suitable lifting equipment lift the hopper cradle into place over the shaft on the
mainframe and fit both links, secure the links to the shafts using the flat washers and
nuts, check the hopper cradle lifts freely and refit the grease nipples into the shaft
ends.
The pivot pin supporting the roller is retained in the operating bracket attached to the
rear of the hopper cradle via a grubscrew, remove the grubscrew and using a
suitable drift and soft faced hammer knock out the pivot pin and catch the roller.
