WHEEL BEARINGS
Every six months, the Wheel Hubs should be removed. Remove, clean, and inspect the bearings making
certain that they are free of all signs of pitting, rust, decay, or deformation. If any of these problems exist,
the Cups and Cones in the Wheel Hub should be replaced. Replace the Cups and Cones as a set. This
prevents a continuation of the original problem. If the bearings are in good shape, pack them with grease.
Put the Bearing and Seal back into the Wheel Hub and replace the Hub. Tighten the adjusting nut until
there is noticeable drag while turning the Wheel. Back off just enough to provide a free-rolling fit. Insert and
spread the Cotter Pin. Install the Hub Cap. Fill the Hub completely with #2 Bearing Grease.
HARDWARE
Check nuts, bolts, and other miscellaneous hardware regularly. Loose hardware is easily lost, causes
increased wear on parts, and increases the chance of breakdown. Loose hardware creates potential
hazards which could result in personal injury to the operator, support personnel, and bystanders. Use the
“Torque Chart” below when tightening bolted connections.
HYDRAULIC HOSES
Replace pinched and broken Hydraulic Hoses at once. Tighten any Hydraulic Fitting with fluid leaking from
it. If fluid still leaks, loosen the fitting, apply a pipe thread compound to the threads and tighten. Care must
be exercised when tightening Hydraulic Fittings. Too much tightening can cause the fittings to crack and
require replacement fittings.
Although a small amount of oil will be present from bleeding at all Hydraulic Fittings, significant amounts of
oil leaking around the Breather Plug on the Cylinder indicates that the seal in the Cylinder is worn out.
Replace the seals in the Cylinder immediately before the Cylinder is damaged or too much hydraulic fluid is
lost.
SKID SHOES
Skid shoes are made of carbon steel to reduce wear and increase service life. Premature wear can be
caused by the cutter Wing sections being set too low which allows the Wing Skid Shoes to drag on the
ground. Dragging the Skid Shoes on the ground or running the Skid Shoes into solid objects can contribute
to early frame failure on the cutter. Replace worn Skid Shoes as required.
