AUGER GEARBOX

Gearbox Assembly

1. Use a wire brush or ﬁ ne sandpaper to clean the

auger shaft. A clean, smooth shaft will help avoid

damage when installing new bushings and seals.

Clean the old seal material from the case mating

surfaces. Scrape, then use liquid gasket remover.

(Fig. 092).

2. If new bushings are to be installed in the gear case

halves, now is the time. Apply a thin coat of Loctite

Blue #242 or equivalent to the OUTSIDE of the

bushing and press in ﬂ ush with the INSIDE of the

case (Fig. 093). This will allow space for the seal on

the outside. Wipe up any Loctite that is visible. The

Loctite must not get into the gear or seal area.

4. Install the thrust washers and slide the case halves

on. Note the direction to keep the gear markings on

the right side.

Fig 094 MVC-047X

3. Insert the key into the shaft and slide the worm gear

into place. Note: There is a large letter R and an

arrow stamped into the side of the gear. This gear

MUST be installed such that the R and the arrow

are on the right hand side and the arrow is pointing

forward, from the operator’s point of view (Fig. 094).

This is a two-piece gear that is bonded together. If it

is installed backwards, the forces try to separate the

gear and can result in failure.
