Some Remanufactured Electric Starter Groups May Have An Incorrect Nose Housing Caterpillar

Problem:

Some of the above remanufactured electric starter motors may have been assembled with an incorrect nose housing (see Illustration 1). This can cause the starter motor pinion to not engage correctly. This can result in shortened starter motor life.

Solution:

Inspect all inventory of the above remanufactured electric starter motor groups to determine if the correct nose housing is installed. To determine if the correct nose housing is installed, a simple visual inspection of the locations of the nose housing retaining bolts must be made. If all the nose housing retaining bolts (1 through 6 in Illustration 2) are the same distance from the base (X) of the nose, the CORRECT nose housing is installed. If all the nose housing retaining bolts are not the same distance from the base (X) of the nose, [see that holes (1) and (2) are closer to the base (X) than holes (3) through (6) in Illustration 3] an INCORRECT nose housing is installed. Any starter with an incorrect nose housing should be returned to:
