Select New Outer Bushing

Select new outer bushing either:
Narrow:

198-360D OUTER BUSHING INNER CUP SEAL

or
Wide:

404-214D 25P O-RING BUSHING

Insert U-type Seals

Note: Do NOT damage the new seals by inserting them

in the wrong direction. If these instructions are fol-
lowed the seals will not be damaged. When the
inner bushing passes through the inside of the
outer bushing it must not cut against the sealing
edge.

Note: The notch

on the eccentric bushing

must

face down and to the outside of opener arm.

Select one U cup seal

Make sure U-shape part of seal (the open end)
faces OUT and not into the groove. Insert it in one
end of the new outer bushing

. Make sure the

seal is placed securely in groove.
MAKE SURE TO ONLY INSTALL ONE SEAL AT
THIS TIME.

Before sliding the inner eccentric bushing

into

the outer bushing

put a small amount of grease

over the seal

to lubricate. This makes it easier to

push the bushing through so it doesn’t damage the
seals.

10. Take the eccentric bushing

flat end (not notched

end

) and slide it in the opposite end (end without

the seal). Push all the way through so it extends a
little past the end with the seal to allow room to get
second seal in.

11. Select second U cup seal

Insert making sure U-shape part of seal (the open
end) faces OUT and not into the bushing groove.
Make sure it is securely in groove. Apply a small
amount of grease over the seal

to lubricate.

12. Push inner bushing

through this seal so it is cen-

tered inside outer bushing
