Starter Cup
The starter cup can either be cast into the flywheel or
be a steel cup that is bolted to the flywheel depending on
the application.
1. Inspect the inside of the starter cup. See Figure 6.3.
NOTE: If the starter was failing to engage the fly-
wheel, and the edges of the teeth inside the
cup are rounded, replace the flywheel or
starter cup.
NOTE: If the flywheel or starter cup is replaced, the
complete starter should be replaced as well,
to prevent a repeat failure.
2. If the engine has a steel starter cup, remove it by
removing the flywheel nut.
3. Install a starter cup by placing the starter cup on the
flywheel allowing the protrusion on the bottom of the
starter cup to rest inside the dimple in the flywheel.
See Figure 6.4.
4. Install the flywheel nut and tighten it to a torque of
47 - 52 ft-lbs (64-70 Nm).
