Rear bushing is a larger diameter than one in front,
but are identical in design. Replace if necessary.
Remove eight bolts that hold right and left gear
case halves together (Figure 26).
10.If replacement of thrust collar is necessary, drive
out groove pin towards direction of least
resistance.
If flange bushings need replacement, first remove
seals from outside of gearcase halves with a
screwdriver. Flange bushings can then be pressed
out from outside in with a bearing driver. Bushings
are very lightly pressed in.
11.Inspect worm shaft for burrs or black coloration. If
either show up, replace shaft.
12.Prior to re-assembly, apply anarobic sealant to a
clean surface. Allow to cure for 24 hours.
Reassemble. Make sure the flats on the bushings
are in their proper place.

When replacing bushings make sure the flat on the
flange of bushing fits in the inside notch of the
case.
There are two special thrust washers, one on
either side of worm gear. If burred or worn, they
should be replaced.
This case requires Ariens L-2 P/N 00008000 and
should be half full.
After assembly is complete you should be able to turn
input shaft freely.

Holding the worm gear on rake shaft is a wood ruff
key.
Auger/impeller gearcase is lubricated with Ariens L-2
(P/N 00008000). Check lubrication by removing filler
plug. Lubrication should be even with hole with unit
sitting level. It may be necessary to insert a wire into
the hole to check level. Unit will not be damaged by
over-lubricating.
Remove bronze bushing from front of worm shaft
by sliding it off. Replace if necessary. Notice that a
flat on the bushing flange positions the bearing
inside the gearcase.
