INSTALLATION
These instructions are provided as supplementary information to the factory
service manual instructions for starter replacement.
The box contains: (1) starter, (2) mounting bolts, and (2) shims.

. Make sure the mounting surface of the engine block is smooth, flat and free of paint buildup.
Torque starter mounting bolts to engine manufacturer’s specifications, typically 32 ft. lbs. If the starter motor is interfering with
the engine block, remove the two socket head cap screws securing the mounting block to the starter and rotate the mounting
block to another clocking position for increased clearance. (See box “Installation Instructions for Internal Shim”)
clocking Instructions for InficLOcK, and Installation of Internal shim
After the starter has been installed, there should be 1/16” (0.062) minimum between
the engine side of the ring gear and the front
edge of the teeth on the starter pinion gear. Check this distance with the ring gear in at
least three different positions. If the
distance is too small, a shim can be installed inside the starter, which will increase this
clearance an additional 0.062”.
1. Mark the starter body to starter block position so it can be correctly positioned
during reassembly.
2. Remove the two bolts that retain the infi-CLOCK ring using a 3 mm hex key.
3. Remove the ring and block.
4. Install the shim and reassemble as shown, (fig. 2).
5. Rotate the block into position and tighten the two ring bolts. The bolts must be
tightened evenly. While holding the ring parallel to the block, lightly snug each bolt.
Evenly tighten the bolts in an alternating pattern. Torque to 50 in/lbs. Inspect the
ring again to be certain it is parallel to the block.
6. Reinstall the starter to the engine.
IMPORTANT!
It is critical that the infi-CLOCK ring be tightened correctly!
*Powermaster recommends
that no more than one internal
shim be installed in a starter.
*Ring and block face
must be parallel after
clocking is complete.

. There should be 0.060”~0.140” clearance from the face of ring gear to the front face of the starter
pinion. Check in at least six locations on the ring gear
(see Figure 1)
. If not in spec, verify that the ring gear is properly mounted and
does not have excessive runout. The included shims can be installed between the starter mounting block and the starter’s center
support to increase this distance. (See box “Installation Instructions for Internal shim”).
Using Blue Loctite® on the two ring bolts is recommended.
