Photo 8/15), put the cover on a surface that
will allow you to put the tiller shaft in the cover
and pound it with a mallet-see Photo 8/16.
Just put the bearing cone and the shaft in the
cup (mounted in the cover, part #1023, with no
seal installed). Make sure that the shaft has
enough clearance
to be driven down. Then, hit
the shaft down until it stops moving. Turn the
shaft
over and repeat the process. This will
cause the bronze
tiller worm gear to align it-
self in the center of the tiller shaft. The key
should not protrude out of the keyway any fur-
ther on one side than it does on the other-see
Photo 8/17.
When this is
done (if it is even necessary, be-
cause most times the
tiller shaft will come out
of the housing without disturbing the position
of the worm gear), replace the tiller shaft in-
side the tiller housing, as shown in Photo 8/18.
Please Note: If
you have difficulty and find that
you cannot drive the bronze tiller gear cluster
but the left side of the tiller housing, the steel
worm on the main
drive shaft is probably block-
ing your way. Simply pull up on the left side of
the tiller shaft, while you simultaneously press
down (hard) on
the right side. This action
should deform the oil seal on the right side and
provide the added clearance
you need to ex-
tractthe ti ller gearcluster.
HOW TO REPLACE TILLER HOUSING SEALS
Before replacing the right or left tiller shaft
seals, carefully inspect the keyways in the tiller
shaft (part #1026) to make sure that there are
no sharp edges. Here too, file lightly to avoid
cutting the new seal being installed. Apply a
non-hardening Permatex, Loc-tite, or Plasgon
gasket sealer
to the outer metal surface of the
new tiller shaft seal before you install it. .
A mechanic's
thin walled metal sleeve is the
best
way to protect the seal from being cut and
to seat it properly. If you have no metal sleeve,
you can cover the keyway
with transparent
tape. You should install a right tiller shaft seal
extremely carefully, by tilting the seal on the
bottom side of the shaft as you pass it above
the keyway on the top of the shaft, then pivot-
ing the seal up over the keyway, as shown in
Photo 8/19. This will keep the seal away from
the keyway during the process. Then, put gas-
