- Fit the half-pulley on the bushing being careful
not to damage the top sealing ring.
- Make sure the pins and collar are not worn and
refit the pins and the collar.
- Using a curved-spout grease gun, lubricate the driven pulley assembly with approximately 10 grams
of grease. Apply the grease through one of the holes in the bushing until grease comes out through the
hole on the opposite side. This procedure is necessary to prevent the presence of grease beyond the
O-rings.
