3/4 inch Greasable Center Bolt

3/4-inch Greaseable Center Bolt

3/4-inch Greaseable Center Bolt secures Manutec’s roller springs to the centre rocker arm. The bush on this rocker cannot be replaced.

Steel on steel parts requires grease to help reduce wear and tear.

Use a nylock nut or standard nut with a spring washer.

Nylon or Polyurethane are self-lubricating spring insert bushes that do not require greaseable shackle bolts.

Installation of Shackle Bolts

Insert the bolt through the hanger bush and push until the thread appears on the other side of the hanger. Tap the bolt with the hammer if the bush is tight until the thread appears.

Tighten the nylock nut with a spanner. If a rattle gun is used to tighten nylons, then the nylon thread will likely be heat damaged.
