7Nut Posted April 23, 2011 Share Posted April 23, 2011 After having to bail out of being squadron leader for the Essex blat on 20th March, I've finally been able to get the diff out. An inspection of the diff has found two teeth on the big crown wheel are missing Looks like I'll be going to Phil at Road and Race Transmissions on Tuesday. Enjoy the sunny blatting Edited by - 7Nut on 26 Apr 2011 17:01:15 Link to comment Share on other sites More sharing options...
Dignity Posted April 23, 2011 Share Posted April 23, 2011 Hi Stew, I too am off the road. Front Hub Very frustrating but I have taken the opportunity to carry out a fair bit of maintenance that I couldn't get motivated to do in the cold winter Good luck with the Diff Regards Dignity Link to comment Share on other sites More sharing options...
blade_runner Posted April 23, 2011 Share Posted April 23, 2011 Stewy, have you checked Phil has a 3.27:1 ratio CW&P? there gettin hard to get hold of... unless the one in your spare open diff is in a serviceable condition..? I got mine at Rimmer Bro's brand new Ex BL stock... although the quality of the british leyland steel is not the best. there was a thread on here somewhere about Jigsaw racing selling CW&P's made in Germany from better quality steel, whether they sell a 3.27:1 remains to be seen.

bstark Posted April 24, 2011 Share Posted April 24, 2011 The quality of the Jigsaw cw&p is in a different league to BL NOS Looks like they do a 3.27 for the Spitfire at least here so worth a call. Have a 3.63 in my 4 speed Supersprint and found them very pleasant to deal with. R+R did the work via 7 Indulgence. Link to comment Share on other sites More sharing options...
7Nut Posted April 24, 2011 Author Share Posted April 24, 2011 Thanks for all the comments chaps Steve, I've had a look at the crown wheel in my open diff and all seems well. Measurements of each wheel (good and knackered) seem to me to be the same, so I'm hoping it'll be a straight swap. Will definately look into getting a spare crown wheel and pinion.

7Nut Posted April 26, 2011 Author Share Posted April 26, 2011 So I've just got back from seeing a diff expert in town and my open diff crown wheel is not looking to pretty either As Steve says, the 3.27:1 crown wheel and pinions are getting hard to get hold of. If I can't find one, whats the next best one to fit 🤔 Cheers, Link to comment Share on other sites More sharing options...
7Nut Posted April 26, 2011 Author Share Posted April 26, 2011 Oh, I forgot to say, I'll be calling Jigsaw in the morning. Thanks Bob Link to comment Share on other sites More sharing options...
simonpa Posted April 26, 2011 Share Posted April 26, 2011 I'm just considering putting my Blackbird-engined SV back to K-series and would have the diff available. It's the standard 3.14 version - non-LSD (at least I don't think it has an LSD). The car has done 6k and there appears to be very little backlash on the diff.

Area Representative Nick Chan Posted April 26, 2011 Area Representative Share Posted April 26, 2011 Simon, I think the faulty diff is in a live axle casing Link to comment Share on other sites More sharing options...

Andrew G Posted April 27, 2011 Share Posted April 27, 2011 Hi Stew Was chatting to the father-in-law about this, he said to try Moss-Europe as they do a lot of stuff for triumphs etc. What about crossing the divide and asking on the Westfield forums?

blade_runner Posted April 27, 2011 Share Posted April 27, 2011 Stew, try Jigsaw racing first, then Rimmer Bro's, there should be some about, I'm sure someone will either have a few left, to be making new ones. £256 in stock at Rimmer Bro's Link to comment Share on other sites More sharing options...
