Introduction
It is assumed that personnel involved in either the assembly or repair of Winget
Mixers will be familiar with the product, either through the operation of, or
previous repair and maintenance work. It is not intended to be used by
personnel who are neither familiar with the product nor mechanically
inexperienced.
It is also assumed that personnel are aware of Health and Safety Regulations,
which should be applied to all working practices but the following should act as a
reminder.
Ensure all work tools are in good condition.
Always wear Safety Spectacles when using soft or hard faced hammers, chisels
or when using air tools. Wear Safety Spectacles when cleaning hardened
concrete or mortar deposits off components. Do not misuse airlines and be
aware of the damage compressed air can cause if misused.
Always make sure lifting equipment is in good condition and the marked Safe
Working Loads exceed the weights of the components to be lifted.
Oils, fuels, silicone sealers and open gear lubricants can cause skin diseases if
allowed to contaminate the skin. Always apply barrier creams, wear suitable
protective clothing, or when contamination is unavoidable clean the area with
soap and water as soon as possible. Do not use thinners or other solvents to
clean skin.
Health and Safety is a matter of common sense. If common sense is applied
correctly Health and Safety can be improved and the risk of accidents reduced.
L/H and R/H views are taken when standing directly behind and facing the
engine housing.
Refer to the Parts Books for a guide to the correct sequence for assembling
components and sub-assemblies.
Whilst every effort is made to ensure the contents of this manual are accurate,
Winget Limited reserve the right to altar specification without prior notification and
certain sections may then no longer apply.

Lifting Points
A lifting point capable of supporting the weight of the mixer is incorporated into
the trunnion.
This lifting point is highlighted with an ISO ‘Hook’ symbol adjacent to the point.
On Military/NATO mixers the lifting point will also be painted white.
Draw Bar Replacement-Four Wheel Tow
The drawbar is secured to the front axle using split pins and flat washers.
Remove the split pins and flat washers slide the old drawbar out of the lugs on
the front axle. Replacement is a reversal of the above procedures ensuring
that the eye on the drawbar points downwards.
Wheel Replacement-Four Wheel Tow
Solid rubber cushion and steel wheels are secured using split pins and flat
washers and the removal procedure is identical. Lift and support the axles.
Remove the split pins and washers. Clean the axle shafts and coat with
copperslip. Fit the new wheel replace the flat washer and secure using a new
split pin.
Wheel Replacement-Two Wheel Tow
On two wheel tow mixers the pneumatic tyre/wheel assembly is secured to the
hub/suspension unit by four nuts. To change a wheel, chock the wheel on the
opposite side, slacken but do not remove the wheel nuts securing the wheel to
be changed. Place a suitable jack below the suspension unit and jack up the
mixer until the tyre is just clear off the ground, remove the nuts and wheel
assembly. Reverse the procedure to refit and fully tighten the wheel nuts
when the jack is removed.
It is recommended that the wheel nuts be rechecked following a short “road
test”
Hub/Suspension Unit Replacement-Two Wheel Tow Mixers
The suspension units require no maintenance being a sealed unit having an
internal construction of rubber and ends sealed with nylon bushes.
Suspension units should not be subjected to heat such as welding or oxy-
acetylene cutting as this will damage the rubber and nylon components.
The suspension units are secured to the mainframe using six/eight bolts and
nuts to remove, slacken the wheel nuts, jack up and support the mainframe on
suitable supports. Do not attempt to work under the mainframe if it is

supported only on a jack. Remove the wheel nuts and wheel assembly. Unbolt
and remove the mudguard and supporting bracket. Remove the remaining
bolts securing the suspension unit and detach the unit from the mainframe.
Note: it is recommended that suspension units be replaced in pairs.
Reverse the procedure to refit.
Wheel Hubs & Bearings-Two Wheel Tow
A single castle nut and flat washer retains the hubs to the stub axles of the
suspension units. The castle nut is also secured with a split pin; this is
accessible after removing the steel/plastic dust cap.
The bearings are automotive type taper roller bearings requiring a small
amount of end float.
To remove the hubs remove the wheels as described above, prise off the dust
caps. Remove the split pin, nut and washer and pull off the hub. Do not allow
the taper roller or ball bearings to drop to the floor where they will become
contaminated with dust etc. The later type inner taper roller bearing and seal
unit will normally be left on the stub axle when the hub is withdrawn, this can
be carefully tapped off using a suitable drift taking care not to damage the
bearing cage.
Clean all traces of old grease out of the hubs and off the stub axles, using a
suitable drift knock out the old bearings, pack the new bearings with grease
and tap home into the hub.
To adjust the taper roller bearings, tighten the nut then back off 1/4-1/2 a turn,
check that the hub spins freely without to much end float, .004” is sufficient.
Align the castle nut with the split pinhole in the stub axle and fit the retaining
split pin. Recheck the hub rotates freely and refit the dust cap. Charge the hub
with grease until the grease is visible in the breather hole in the cap.
It is recommended that the wheel bearing adjustment be rechecked after
giving the mixer a short “road test”.
Front Axle Replacement- Four Wheel Tow
The front axle is designed to rotate through 360, it does not oscillate and the
front axle swivel pin locates directly into the front leg of the mainframe where it
is secured via a spiral pin.
Jack up and support the mainframe and knock out the spiral pin. Remove the
axle. Replacement is a reversal of the procedure however the pivot pin and

axle shafts should be coated with copperslip. The axle should be rotated
through 360 degrees making sure the spiral pin does not foul the mainframe.
Drum Removal
Attach suitable lifting equipment through the drum blades. Knock back the
tabs on the lock-washer securing the drum shaft setscrews. Remove the
setscrews and the washers securing the shaft and flange. With the drum
mouth upright lift the drum assembly clear of the trunnion. It may be
necessary to rock the trunnion via the tiltwheel to free the shaft, especially if
the mixer has been in service for some time.
In exceptional circumstances it may be necessary to use a commercially
available two-leg puller/pusher tool to assist in pushing the drum shaft through
the trunnion. When using such tools please ensure the manufacturers or
supplier’s instructions are adhered to.
Drum Re-Fitting
Clean and lubricate both the drum shaft and trunnion base plates with
copperslip. Coat the bevel pinion and bevel gear with open gear lubricant.
Attach suitable lifting equipment through the drum blades; lift the drum
assembly and position over the trunnion.
Turn the drum shaft so the threaded holes in the shaft are at 90 to the holes
in the lower base plate. Lower the drum and shaft assembly into place
making sure that the bevel gear and pinion are fully in mesh and the drum
shaft is fully through the base plates.
Slip the lockwasher over the two drum shaft setscrews and coat the threads
with copperslip, using the setscrews secure the flange to the shaft. The flange
can be used to turn the shaft until the remaining holes in the flange align with
the remaining holes in the lower base plate.
Check the number of flat washers required to pack the gap between the
flange and lower base plate. (See “A” on the following illustration).
Deduct one washer from each side. Coat the threads on the setscrews with
copperslip and fit the setscrews with spring washers attached through the
flange and flat washers and tighten into the base Plate. This will lift the drum
shaft slightly back through the trunnion increasing the distance between the
teeth of the bevel pinion and bevel gear. Gently rock the drum assembly back
and forth and check the backlash between the gears. (Approx 3-5mm
measured at drum clip). Ensure the setscrews are tight and knock over the
tabs on the lockwasher.
