AXLE SETTING AND ADJUSTMENT
The axle is set at the factory for proper weight distribution between the hitch and axle, and no
further adjustment should be necessary. Loading should always start at the front of the
mixer/feeder and work towards the back.
TIGHTEN 8-BOLT WHEELS TO 85-105 FOOT POUNDS TORQUE.
DO NOT OVER TIGHTEN WHEEL BOLTS. To do so can crush the raised disc around the bolt
hole, destroying the locking principle built into the wheel for the wheel bolt.
KEEP TIRES PROPERLY INFLATED. An under inflated tire will allow the tire cords to
continually be flexing and chafing the tube with resulting tire failure.
On tires shipped from the factory, the tires are not fully inflated. Inflate tires to proper
inflation before using. Check tire pressure regularly.
WHEEL BEARINGS
Securely block up frame so that the wheel turns
freely. To tighten the wheel bearing, first remove
the hub cap. Remove cotter pin from the slotted
nut, and tighten the nut until there is a slight drag
on the bearing while turning the wheel. Then back
off the slotted nut to the nearest slot and insert
and spread cotter pin. There should remain a
slight drag on the bearing following the
adjustment. Replace hub cap.
