Is the Diff Dead?

[YellowPeril1]

So it was my first day out in the SR4 at Blyton last Monday and what a thrill it was! I built the speed steadily over a few runs and really felt at home in the car. Unfortunately, just before lunch the chain let go and the soft link for the spare I had turned out to be damaged so that was the end of play.

The chain had looked correctly adjusted and was well oiled, but I don’t know how old it was. However, looking at the car yesterday there seems to be loads of play in the diff - surely loads of play in the diff can't be right? I assume this will have contributed to the failure.

With the wheels on the ground I took this video. https://youtu.be/XCfXTpj5JkA

Is the diff dead?! Could anyone advise please?

Thanks,
Nick

Thanks for all your comments guys. One of the chaps at Radical has now had a look at my video and has advised that due to the way it’s designed this amount of play in the diff is normal, so that’s good news.

I now have a new chain and a set of new sprockets ready to fit for good measure. I’ve seen loads of posts about the importance of the sprockets being correctly aligned, however, I can’t find anything much about the correct method of actually adjusting the sprockets to get them into line.

I’d be grateful for any advice on this and also the torque to use for the rear sprocket bolts and the front nut.

Many thanks,
Nick
