Rear Bearing Cap Screws

The three rear bearing cap screws are located under the

depth regulator mounting bracket. If any are loose, it can

cause an oil leak or drive shaft end play. See Fig. 6-3.

Housing Cover Bolts

Check the five bolts securing the tiller housing cover to the

left side of the transmission. Gear oil can leak from a loose

housing cover. To reach the bolts, remove the left side tine

holder. See Tine Replacement in the Service section.

Swing Bolts

Check both of the swing-bolts that connect the power unit

transmission to the tine attachment. Both bolts should be

checked every 2-1⁄2 hours of operation. If loose, wear can

occur on the locating pin on the power unit, and cause

enlargement of the locating hole in the tine attachment.

Using a torque wrench, tighten these bolts to 70-to-80

ft.-lbs.

Lock Nut on the Shifting Linkage

Check the locknut that fastens the shifting linkage to the

eccentric shifting lever. See Fig. 6-3. Do not tighten the

locknut against the eccentric lever. It should be very close

to, but not touching the lever.

Tine Hardware

Check the four bolts and nuts securing left and right tine

holders to the tine shaft. See Fig. 6-4.

Transmission Gear Oil

Checking for oil leaks

At 25-hour operation intervals, check the tiller for oil leaks.

Inspect for oil accumulations on the tiller or the floor where

it is stored.

A small amount of oil seepage or wetness around a

shaft opening or cover is no cause for alarm. But a heavy

concentration of oil is more serious. You should tighten all

bolts immediately, and replace any worn seals or gaskets.

It may be impossible to determine how much oil has been

lost, so check the oil levels in the PTO transmission and

the tine attachment before using the tiller again. Add any

necessary gear oil. Serious damage to the transmission

components can result from operation when gear oil levels

are low.
