GEAR BOX CARE
The GHU gear box, used on the Ground Hog earth drills is a right angle, worm drive
transmission. It features tapered roller bearings at all bearing points, ground and polished, high
strength input and output shafts, and a hardened worm gear against a bronze drive gear.
Due to its simplicity and high quality components, this type of transmission has proven
itself to be extremely reliable and durable on our earth drills for over 40 years. It is not unusual
for this transmission to be in service for 20 years without major repairs.
If internal repairs are needed, pay close attention to the number of gaskets that are used
on the covers. These are “shim” type gaskets that are color coded to identify thickness. When
replacing internal parts, always start with the same number and thickness of gaskets, adding or
removing gaskets until the shaft turns freely with no noticeable endplay. Use a soft type of
gasket sealer on the inside flange of the cover during final assembly. Use 1 quart approx of a
#140 gear lube.
