Replace Ring Gear
All Briggs & Stratton engines use an aluminum,
plastic, or steel ring gear on the flywheel.
Replace the ring gear if it shows wear or
damage. Some steel ring gears are pressed or
heat shrunk to the flywheel. These ring gears are
not replaceable.
To replace a worn or damaged flywheel ring
gear, proceed as follows:
1. Mark center of rivets holding ring gear
(A, Figure 18) to flywheel, with a center
punch.
2. Drill out rivets using a 3/16” (4.7 mm) drill
bit.
3. Remove the ring gear and clean holes
after drilling.
4. Attach new gear to flywheel using four
screws (B) and lock nuts (C) provided with
the gear.

Check Starter Drive and Clutch
When starter switch is activated, pinion gear
(A, Figure 19) should engage the ring gear and
crank engine. The clutch should not slip during
engine cranking and pinion gear shouldn’t bind
on the helix (B).
NOTE: Do not oil the pinion gear or helix.
1. Remove the starter from the engine.
2. Using a mild solvent, clean the drive and
clutch assembly, then dry with
compressed air.
3. Inspect for damaged parts and replace if
necessary.
4. Install starter on engine and test for proper
operation.
5. Replace the entire starter drive assembly if
the clutch slips or if the pinion gear binds
on the helix.
