OEG Parts 16-Tooth Starter Pinion for Briggs & Stratton 12V CCW — Fits 1972–2002 Engines, Direct-Fit Replacement

OEG Parts 16-tooth starter pinion is a direct-fit 12V, counterclockwise replacement designed to restore reliable engagement on a wide range of Briggs & Stratton and compatible engines from 1972–2002.

This starter pinion is a new aftermarket replacement engineered for small engines and lawn equipment that use a 16-tooth, CCW rotation starter drive. It reproduces the correct tooth count, shaft profile and 12-volt specification so the starter engages the flywheel properly. The part is supplied without mounting hardware and is manufactured in China to match many factory replacement numbers for straightforward swap-ins.

Will this pinion fit my Briggs & Stratton engine?

If your engine lists a 16-tooth starter pinion and uses a 12V counterclockwise starter, this unit is likely compatible. It covers many Briggs & Stratton air-cooled models from the early 1970s through 2002 and cross-references numerous OEM numbers and aftermarket part codes.

• Tooth count: 16 teeth for correct flywheel engagement
• Voltage & rotation: 12V, counterclockwise (CCW)
• Cross-reference: replaces parts like 41022003, 41022003R, 41022052, 497595 and others
• Check: compare your engine’s starter part number and shaft fitment before ordering

How do I install the replacement starter pinion?

Installation typically requires removing the starter assembly from the engine, pressing or sliding off the old pinion, and fitting the new pinion to the starter shaft. Because this part is sold without mounting hardware, retain or reuse the original retaining clip, spring, or washer unless a new retaining kit is obtained.

• Tools needed: basic socket set, pliers, small punch or pin removal tool
• Procedure: remove starter, disassemble drive, replace pinion, reassemble and test
• Tip: confirm shaft diameter and retaining method match your existing starter

What engine brands and models are covered by this pinion?

This pinion is engineered for a broad set of small engines and equipment beyond Briggs & Stratton, including select John Deere and Evinrude applications. The listing includes compatibility with many model years—always compare the reference numbers and tooth count to ensure fit.

• Briggs & Stratton: air-cooled engines across 1972–1986 and 1988–2002 eras
• John Deere: models such as 100, 9520RT, 108, L111 and others within listed years
• Evinrude: select TE10REL and TJ10REL 1993 models
• Additional references: multiple OEM and aftermarket numbers listed in product features

What should I verify before purchasing?

Before ordering, confirm the required tooth count, rotation direction and 12V specification, and compare cross-reference numbers on your old part. Because mounting hardware is not included, plan to reuse existing components or purchase retaining clips separately.

• Verify: 16 teeth, 12V, counterclockwise rotation
• Compare part numbers: e.g., 41022003, 394805, 497594, 693054, STR1001A listings
• Confirm shaft dimensions and retaining method match your starter

Who is this for: This replacement starter pinion is aimed at DIY mechanics, small-engine repair shops and owners of lawn tractors, mowers and compact equipment who need a cost-effective, exact-tooth-count starter drive.
