Aftermarket Crankcase Bearing Set for Stihl Professional Chainsaws
Restore the smooth, high-RPM performance of your saw with this premium non-genuine Crankcase Bearing Set. This complete kit includes both the clutch-side and flywheel-side bearings required for a full bottom-end rebuild. Engineered to meet or exceed OEM standards, these bearings provide the durability needed for the intense heat and rotational speeds of professional logging saws.
Heavy-Duty Construction
Featuring a high-quality grooved ball design, these bearings are precision-fit for Stihl's legendary 70cc+ chainsaw class. Replacing OEM 9523-003-4278 and 9503-003-0346, they are built to handle the heavy side-loading of the clutch and the high-vibration environment of the flywheel.
Full Compatibility List:

⚠️ Maintenance Alert:
Worn bearings often reveal themselves through increased vibration or a "rumbling" sound during deceleration. If left unaddressed, bearing failure can cause the crankshaft to wobble, instantly destroying the crankcase or the cylinder through piston slap.
🛠️ Installation Tip:
For easier installation, professionally freeze the bearings for several hours and warm the crankcase gently with a heat gun before pressing them in. This thermal expansion/contraction method allows the bearings to drop into place with minimal force, preventing damage to the bearing races or the aluminum case.
