Axle doesnt grip flywheel

Post by D.elisius » January 9th, 2022, 2:11 pm

Hey Everybody

Im in need of some advice

I just purchased a model c

The first pull is good and the flywheel goes around, but Then at the second or third pull the axle rotates but it doesnt grip/lock the flywheel, so no resistance

I tried taking the flyveren out and cleaning the axle etc, but the problem Is still the same

The sprocket is good and so is the chain

So what am i missing here?

My guess, not an expert, verify before you buy parts.

https://www.concept2.com/service/indoor ... resistance

"Symptom
There is a complete loss of resistance during the drive. There is no noise associated with this loss of resistance.

Resolution
This usually means that the clutch is not engaging due to the lubricant within the clutch becoming contaminated or dried out, preventing the clutch from engaging. A new balanced flywheel assembly will fix the problem."


Also could try this procedure before replacing. From this thread: viewtopic.php?f=10&t=202712&p=543349#p543349

" Missing is reference to a procedure for freeing the clutch bearing needles endorsed by ‘c2Jon’ Wilson (long time Concept 2 employee, now retired, who has reason to know), in which the original grease lube is dissolved and flushed from the bearing bore by liberal application of kerosene prior to relubing with a low viscosity oil. Should be done with flywheel removed from axle and placed on rags or absorbent waste to catch excess kero and lube."

Also, if you can drive out a bearing and replace then talk to Carl Watts about an upgrade bearing vs a new flywheel assembly. Pros/cons for this. Some reading. viewtopic.php?t=163933 viewtopic.php?t=157466
