Hello ripperdog3

The gearbox will have two Allen head plugs. The lower one is for draining the existing gear oil. I would recommend you do that first. Then reinstall the Allen head plug.

Then remove the upper plug and with the machine level, fill the gearbox with gearoil. Either a 90 or 140 weight gearbox oil will be okay.

The oil your finding on the tines or shaft may be coming from defective seals on the shaft extending out of the lower gearbox.

Clean the area. Run the engine with the tines revolving but not in soil. Check for roundness of rotation. A shaft may be slightly bent and should have a visable out of round rotation.

During this proceedure, if there is seal leakage, gearoil will become visable on the shaft. That seal is the defective part. Both seals should be replaced if one seal is found to be leaking.

Other locations to check for oil leakage is the upper gearbox seals. All locations between housings and componets should be checked. Gaskets may be leaking also.

A service manual for the specific tiller model would be a huge benefit prior to any disassembly. A worth while investment for the Do-It-Yourself person.
