As above...how do you tension your chain? Any pics of your setup would be great

Im going to instal a new chain when things warm up a bit and thought id get a few ideas from those in the know

When I was into nikes back in the day, I found the quickest way was to twist the throttle. Failing that a chain tesioner works quite well.

If it's gone really slack put a bigger sprocket on I would think it's not so critical in a car application as there is no movement compared with a bike swing arm. A sprung arm with a dérailleur type roller setup would be enough.

Remembering a certain TV programme that shall remain nameless, on that car the rear diff was movable back and forth by a small amount, any bigger slack was taken up by removing links.

Just don't get someone else to hold the chain while you use a hammer to press the pins out...

Whatever you do needs to be very rigid, simplistically look at go-cart tensioning systems where you have the engine sliding on rails that are adjusted with a bolt to push the carriage forward and clamps to the bed.

In your case it is probably easier to fix the engine solidly and move the diff.

You could slide aka go-carts or have a pivot, whatever you do it will need bracing between either end of the chain, think motorbike, you would have a big fat swinging arm between the two sprockets.

Regards Mark

Some diffs are pivoted in a carrier, some slide in a diff carrier, yours looks like it would be shimmed going by the photos in your gallery

If i was to shim it, would i risk over tensioning the top? Its the bottom of the chain that was too loose?
