a.
Cam follower (12)
1. Clamp fixture J5840 securely in a vise. Then place the cam
follower in the groove in the top of the fixture, with the follower
pin resting on top of the corresponding size plunger in the
fixture.
2. Drive the pin from the roller with a suitable drift. Exercise
caution in removing the cam follower body and roller from the
fixture as the roller pin is seated on a spring-loaded plunger in
the fixture.
3. Before installing the new roller pin, remove the preservative by
washing the parts with clean lubricating oil or Cindol 1705 and
wipe dry. Do not use fuel oil. After washing the parts, lubricate
the roller and pin with Cindol 1705.
4. Position the cam follower body in the groove of the fixture, with
the small plunger extending through the roller pin hole in the
lower leg of the fol-lower body.
5. Position the new cam roller in the cam follower body. When
released, the plunger will extend into the roller bushing and
align the roller with the cam follower body.
6. Start the new pin in the cam follower body, then carefully tap it
in until it is centered in the cam follower body.
