Concept2 Forum

Having assessed the rower I have 1 link that is a little tight. It does not effect the machine at the moment when rowing. I am told by concept 2 that I need a chain and sprocket kit (1915 i think) as the original sprocket if different. They also suggest I need to change the sprocket shaft at the same time.

Has anyone done this?

Seems to me that if I am changing chain, sprocket, shaft with the fan off, etc I am taking 80% of the machine apart, I might as well change the bungie cord also.

My question is what order do you need to take the machine apart to be able to do this job?

Is it really worth it on a machine built in early 2003? Would I be better off buying a complete new machine? (Parts are £74 for the chain and sprocket kit.)

Cheers.

if the fix is only £74 that's considerable less than a new machine - so if that's all it needs, and you're happy with everything else, I'd say get it fixed.

Yes, the machine is worth it but do you really need to replace the chain?

If it is just seized you can probably loosen it by oiling and wiggling. Maybe work up a jig so you can soak it in mineral spirits first. A wire through the chain can be tied to the guide to keep it extended for this purpose.

You say it doesn't affect rowing. Is that because it still goes over the sprocket, or because it is at a place on the chain that doesn't pass the sprocket?

Doesnt go over the sprocket. Its a link just by the entrance to the machine when the handle is in its resting position. You can see it come over the guide every row.
