Product Description
3908546F Flywheel Ring Gear is the outer toothed ring press-fitted onto flywheel for JAC ISF3.8 diesel engine. Its gear teeth mesh precisely with starter pinion to transfer driving torque and rotate crankshaft for engine ignition. This aftermarket replacement ring gear fixes hard starting, loud grinding noise during cranking and starter drive damage caused by tooth chipping, surface abrasion and tooth profile deformation of old ring gears. Reliable meshing reduces starter motor load and avoids cranking failure for JAC light trucks operating on long-distance freight and heavy-load delivery routes.
Product Advantages Fabricated from medium carbon alloy steel with integral tooth surface quenching for excellent impact resistance and wear resistance. Precision hobbed tooth profile guarantees smooth engagement with starter pinion and less meshing noise. Standard outer diameter and tooth quantity match the flywheel groove for tight interference press fit. Every ring gear undergoes tooth inspection and hardness test before packing, OEM specification for press installation during engine overhaul.
