New chain and sprockets?

Posted by david_green at August 19. 2017

Hi,

I have a '61 99 Dominator that I'm working on and I plan to replace the final drive chain. Is it mandatory to replace the final drive sprockets, gearbox and rear wheel, at the same time as I replace the chain?

 

cheers,

David

Depends on the wear to the sprockets. Sometimes on the bike. A Suzuki GS550 I had in the '80s used to eat chains and sprockets in one sitting. But I just put a new chain on my '74 Mk2A, the sprockets were fine. You can usually see how worn the sprockets are by comparing the driving side of the teeth with the other side. Given that I've previously moaned about one supplier, let me try to balance that by giving a huge thumbs-up to Andy the Chain Man, good chain, good price, terrific service. HTH.

Orriginal sprockets were made of very good steel and some survive in good condition especially if chains cleaned and lubricated in the old way.

Sprockets will outlast many chains. As mentioned, you need to assess the condition of the sprockets before making a decision.

The best set-up is where one of your sprockets is a prime number, you get better chain performance and less wear and  more even wear across the whole chain!

Thanks Colin for the insight and recommendation. My previous experience is with Japanese bikes and similar to your example. Once I have the wheel off I'll check for wear and the consider my what I need to purchase.

Hi Robert, I'm unsure of the bikes history, which is why I'm preparing myself to replace chain and sprockets. Good to know that the originals were made to last.

Hi Gordon, I appreciate the response. Will definitely check the condition of sprockets when I take the wheel off to fit a new tyre.

If the sprocket teeth are sharp or hooked, it's time to replace. I once got to the stage of teeth falling off the rear sprocket, but then I was a peniless student at the time! Had to take a job in a sewer to pay for new ones...

Hi Anna, thanks for the response. Current chain is 5/8 x 1/4 and my plan is to replace with the same size chain.

 

Cheers,
