HOT RODS offers this complete crankshaft for YAMAHA YFM 660 GRIZZLY 4WD, YFM 660 GRIZZLY CAMO 4WD, YXR 660 RHINO 4WD 2002-2008. The crankshaft is the engine’s main shaft: the rod turns it and it drives the clutch and gearbox.
The benefits:
Hot Rods crankshafts come assembled and trued: double-forged 8620 steel rod and hardened crankpin (58-62 HRC), a ready-to-fit bottom-end rebuild.
Unusual vibration, a deep knock that follows engine speed or play in the con-rod: the bottom end needs a rebuild.
The manufacturer publishes no hour interval for this model: have the con-rod play checked at every piston change. Cross-Mania guideline: rebuild the bottom end every 2 to 3 top-end rebuilds.
Cross-Mania tip: Take the opportunity, with the cases open, to replace the crankshaft bearings and oil seals.
Check the exact model and year of your bike in the list below before ordering.
