Drive System
Gearbox
The gearbox used on all carts is a heavy duty box and gears that will rarely need repairing.
However, if repairs are required, the gear case can easily be unbolted for replacing the bearings,
seals, gears, and shafts. Often, the gearbox shaft is stuck in the spline bushing of the bottom drive
plate. (Refer to section on bottom drive plate.) In this case raise the bottom auger a few inches.
This will expose the stainless steel bolt located on top of the bottom drive plate bushing. Screw the
bolt in to push the gearbox out of the bushing. Return the bolt to its original position when finished.
The gearbox shaft is NOT fastened to the spline bushing in any way. (See the gearbox drawing for
part numbers.)
Check the oil level in the gearbox every season and check for leaks daily. DO NOT overfill the
gearbox. If oil is leaking from the gearbox, then the seals are probably worn and need replacing.
DO NOT run the gearbox if it is low on oil. Damage to gearbox could be severe.
Assembling Gearbox
When bolting the case halves back together the cleaned surfaces must be primed with Loctite
#19269 and coated with Loctite gasket eliminator #515. The bolts must be torqued evenly (38 to
45 lb./ft.). DO NOT OVER TORQUE. Replace oil in the gearbox (SAE 90).
