ATTENTION

It is very important to check the condition of every gearbox at least once a year. If you find play on any shaft repair it as soon as possible! Failure to repair will cause the gears to mesh improperly, and wear out prematurely. The approximate cost for these gears is $150.00. When the bearings wear out, oil goes out, water and dirt get in, and gears become misaligned causing fast wear, allowing the gears to skip on each other damaging teeth, which requires replacement. The next page shows the different types of drives and describes their failures and solutions.

How to check for wear

Gen 3 T-box; Loosen or remove two 5/16 bolt and nuts fastening motor mount to base mount. Move the motor side to side if any play in bearing, repair immediately.

All wheel boxes; Jack up wheel until tire is off the ground. If any play is in shaft and bearing, or if either the output shaft or the input shaft moves in and out, repair immediately.

The drawing above shows what the gears should look like when new. Dimensions are approximate. If teeth are worn to a point, rounded, chipped, etc. gears should be replaced. The closer in tolerance the gears are, the smoother more efficient and longer they will last.
