Pinion Clearance Check

WARNING: This page is about a different car, the 1998 Pontiac Bonneville, 1998 Oldsmobile Regency, 1998 Oldsmobile LSS, 1998 Oldsmobile Eighty-Eight, and 1998 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Pinion clearance is not adjustable. If clearance is not within specification, disassemble and check starter motor for worn or damaged components.
  1. Secure starter motor in vise with opening in housing accessible for measurement. Disconnect field lead at solenoid terminal "M" and insulate from solenoid field terminal "M". Connect battery negative terminal lead to starter frame. Connect 12 volts to starter solenoid terminal "S". Momentarily touch jumper lead from starter solenoid terminal "M" to starter frame, shifting pinion into cranking position. See Fig 1 .
  2. Push pinion as far as possible away from retainer. Using a feeler gauge, ensure there is .010-.160 in (.25-4.06 mm) clearance between pinion and retainer. See Fig 2 .
