The ring gear is the hardened toothed ring pressed or heat-shrunk onto the outer circumference of the engine flywheel — the starter motor pinion gear engages these teeth to rotate the crankshaft during engine starting. 4.5kg with 50×50×10cm carton or wooden box packaging. 100% professional tested. 7-15 day delivery. Kingstream OEM quality for QuanChai diesel engine forklift fleet operators.

Step 3 — Drive the old ring gear off the flywheel with a hammer and punch, working evenly around the circumference. Step 4 — Clean the flywheel ring gear seat. Step 5 — Heat the new ring gear evenly to 200-250°C for thermal expansion. Step 6 — Quickly position the heated ring gear onto the flywheel with chamfered teeth facing the starter side. Step 7 — Allow to cool for a secure interference fit. Step 8 — Reinstall flywheel onto crankshaft with new bolts and thread locker. Step 9 — Reinstall transmission. Step 10 — Verify smooth starter engagement without grinding. 100% professional tested. Kingstream OEM.
