Sheared Drive Shaft Bolt

[KeithS]

Putting the Griff back in the garage this morning after fetching a 7.5 ft Christmas tree in it (don't ask!), I noticed a patch of oil under the passenger side rear driveshaft and sitting there on the patch of oil was an Allen bolt which had sheared off. A bit worrying!

As the diff has to come out anyway for a recon (I'll be doing the job myself), I need to know where to get new allen bolts and the diff mountings etc, where is the best place to get them? Do I need to go directly to TVR for them?

Thanks in advance!

Go to a nut & bolt stockist and show them what you have. You will most likely be using nylocs so renew them as well You will want high grade bolts not cheapies.

It's a driveshaft bolt that has sheared, are they nyloc bolts, I didn't think there was such a thing??

I'll check tomorrow.

Nyloc nuts not bolts. For the bolts you want grade 12.5 really. Look in the 'phone book under Engineer's Merchants.

Hi Keith,

The nuts have a nylon insert in them which should be used once and after that you use new nuts. Most people don't but you ought to. I assume that your broken broken is one of 4 or 5 that bolt through a flange. If you look at the head of the bolt there may be some letters which indicate the tensile rating and techie stuff like that. If you show this info to a bolt or engineering supplies stockists you will get similar grade bolts for pennies

Thanks for the help but the driveshaft bolts don't have nuts, they go straight into the diff output flange.

Anyway, I'll ring round a few places for the necessary kit, I've sourced a local transmission company to repair the diff.

I'll have to scrape the gunk off the bolt that sheared and see if there are any numbers on it
