Products Description
Q: When should I replace the drum needle cage on my ECHO chainsaw?
A: Replace the needle bearing if you notice the chain jumping off the guide bar, visible scoring on the clutch drum sprocket, excessive side-to-side play in the drum, grinding noises during idling, or if the drum does not spin freely when the clutch is disengaged . A worn bearing allows the drum to wobble, causing uneven chain movement and power loss.
Q: How do I install the needle cage correctly?
The bearing slides onto the crankshaft before installing the clutch drum . Apply a thin layer of high-temperature grease to the bearing during assembly.
Q: What's your delivery time?
A: Normally 15-30days after order confirmation and advance payment.
