Replace with New Bushing and Seals

Refer to Figure 3 and Figure 4

Select New Outer Bushing

7. Select new outer bushing either:

Narrow:

198-360D OUTER BUSHING INNER CUP SEAL

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.

8. 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.

9. 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 .
