F. The shear sprocket uses one 5/8 X 3-1/2” NF grade 8 bolt. Any change from this
specification will void warranty.
POWER TAKE OFF SHAFTS
G. Keep PTO shaft covers in place at all times. Keep universal joints greased. The PTO shear
uses a 5/16 x 2" NF grade 5 bolt. Any change from this specification will void warranty.
AUGERS
Knives
H. Auger Knives should be checked regularly for lose or damaged knives and tightened or
replaced as required. A minimum of grade 5 carriage bolts and lock nuts should be used
because of wear.
I. Rotating knives from high wear areas (middle of auger) to low wear areas (end of auger) will
increase the life of the knife set and maintain a high level of cutting action. Knifes wore past
the tungsten coating and are not effective for cutting should be replaced. Knifes should be set
as close as possible to stainless steel bars on the belly, but must not hit.
Bushings
J. Both augers run on oil impregnated nylon bushings at the front of the mixer. This assembly is
designed to make a metal rubbing metal squealing sound when bushing is wore and needs
replacement. Prolong use at this stage, without replacing bushing, will cause damage to both
the stub shaft and auger sleeve.
K. To change the bushing: - support the auger in the mixer
- remove the stub shaft from the front of the mixer
- remove the wore bushing from the auger sleeve
- tap new bushing into auger sleeve using wooden block
- grease stub shaft and reinstall
- remove auger support and any foreign objects from inside mixer
