Adjustable Wide Front Axle; Single Front; Spacing - Allis-Chalmers WD Operating Instructions And Repair Parts Illustrations

LUBRICATION - Clean and repack with #2 wheel
bearing grease every 30 to 60 days (applies
to all types of front wheels). If wide front
axle is used lubricate four king pins daily
with chassis lubricant.
TIRES - 5.50 x 16 - Air pressure 28 pounds.
The front tires on the "WD " tractor are filled
with solution to the valve level when valve is
at top. Enough air is added'to cause 'a pres-
sure of 28 lbs. See rear wheels for solution
information.
MAINTAINANCE - The front wheels are mounted
on taper roller bearings. At frequent in-
tervals remove weight from wheels and check
for side play. If side play exists it will be
necessary to adjust bearings.
ADJUSTMENT - To adjust bearings: Remove
the hub cap and tighten nut on end of spindle
until all play is removed and bearings have
a free rolling fit; The inside of the wheel
hub is provided with a felt washer to protect
bearings from dirt and to retain grease in
hub. This felt washer should be replaced each
season, or oftener if necessary. The metal
cupped washer is placed with the cupped side
towards the bearings.
SINGLE FRONT - To adjust the bearings of the
single front wheel raise the front wheel from
the ground and block tractor solidly.
Remove wheel assembly from fork. Remove
shims from between bearing retainer and
wheel hub. Adjust the bearings to a free
rolling fit without end play or binding.
SPACING - "WD " tractors are equipped with
reversible front wheels, and may be turned
out to fit certain row conditions such as
following lister ridges.
WIDE FRONT AXLE - Each time the wheel
tread is changed the "toe in" of front wheels
must be adjusted to l/8 I'. To adjust "toe in"
have tractor on level ground with wheels
straight ahead. Measure distance between
tires at front and at rear at hub height. They
should measure l/8" less at front than at
rear. Have steering wheel in straight ahead
position and tighten clamps on drag links.
To determine center or straight ahead posi-
tion, count number of turns of steering wheel
from .right to left and then turn back half this
number of turns.
To adjust wheel tread width, loosen drag link
clamps, remove bolts from axle center bar.
FRONT WHEELS
Slide stub axles out or in to desired width.
The second range of wheel treads given may
be secured by turning the dished front wheel
with dish out.
