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.

Repair & Maintenance Procedures
The following procedures are based in part on the procedures issued to
Distributors and the instructions should be used in conjunction with the
appropriate Parts and Operators Manual or CD ROM. Reference should also be
made to the Parts Listings in Section 9 for a guide to the correct sequence for
assembling components and sub assemblies.
1) Clean any paint or debris from bores and shaft surfaces. Threaded holes
should preferably be cleaned out using the correct tap
2) All sealed for life bearings should be packed with a good quality grease
prior to installation. Carefully remove a seal, pack the bearing with grease
and refit the seal ensuring it is correctly seated.
3) Apart from installing the electric motor, mounting brackets and conduit as
described in this manual under the heading ‘110 volt & 240 volt single
phase Electric Motor.’ All wiring and other work concerned with the
installation of 110 volt and 240 volt components and supply should be left
to a suitably qualified electrician, who is conversant with single phase
electric circuits.
4) The PTOofthe Honda GX160K1 LX4 Petrol engine rotates anti-
clockwise whilst the Lister-Petter LT1/LV1, AC1-05, YANMAR L40/L48
ARE SE and the 240/110V electric motors all rotate clockwise. Therefore
the drum blades and countershaft and sprocket fitted to Honda powered
mixers are ‘OPPOSITE HAND’. When ordering spares it is important that
the correct part number and engine type are quoted. Blades, countershaft
and sprockets intended for use with the Lister-Petter and Yanmar should
not be used with Honda powered mixers and vice-versa.

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.
There are two types of hub bearings in use dependent on the age of the
machine: -
The early type with ball race bearings and spacer, with this type the retaining nut
must be fully tightened.
The later 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.
Assemble the hub and bearings onto the stub axle, in the case of the ball race
bearings and spacer fully tighten the nut and insert the locking split pin. Check
the hub rotates freely and fit the dust cap. Charge the hub with grease until the
grease is visible in the breather hole in the cap.

With 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
Depending on the age of the mixer two different front axle assemblies are fitted.
Early Mixers
Early mixers have a swivel fitted to the front axle, which allows the axle to
oscillate as well as rotate.
Jack up and support the mainframe so the front wheels are clear of the ground.
Remove the circlips securing the pivot pin through the front axle and swivel
bracket. Knock out the pivot pin and remove the axle. The swivel bracket is
secured to the mainframe by a spiral pin, using a suitable drift knock out the pin
and remove the swivel.
Replacement is a reversal of the above procedure however pins and shafts
should be coated with copperslip on assembly. When fitting the spiral pin
through the swivel bracket rotate the bracket through a full 360 degrees making
sure the pin does not foul the mainframe. Fit new circlips and split pin.
Early 175T mixers have a separate bracket bolted to the mainframe into which
the swivel is located. This is secured using four nuts, bolts and washers and can
be removed once the axle and swivel have been removed as described above.
Replacement is a reversal of this procedure.
Later Mixers
On later Mixers the front axle only rotates through 360°, it will not oscillate and
the front axle now 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.

Rear Axle-Four Wheel Tow
Early 175T mixers have a separate rear axle bolted to the mainframe. Jack up
and support the mainframe with the rear wheels clear of the ground. Remove the
nuts, bolts and washers securing the axle to the mainframe and remove the axle
assembly.
Replacement is a reversal of the above procedure.
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
