Tuck2020 Posted June 25, 2020 Author Share Posted June 25, 2020 Next update.John asked me to confirm the type of speedo I had, which has changed over the years. I followed the procedure on the excellent speedo guide, and found that the speedo reading was 041306. My tyre size is 185/60/13 so clearly it's set for the wrong size, however it's good news that it can be changed to accommodate different tyre sizes.

Tuck2020 Posted July 11, 2020 Author Share Posted July 11, 2020 Would anyone who happens to have a driveshaft on the bench , or access to one, be able to put a set of callipers or a tape on the toothed ring and let me know the outside dimension please? I'm just speaking to a company about making the rings.I"ll report back if I make any progress, CC aren't helping much at the mo. cheers Link to comment Share on other sites More sharing options...
John Vine Posted July 12, 2020 Share Posted July 12, 2020 I'd love to help, Adrian, but I'm miles away from my car at the mo.Have you got an accurate figure for the I/D of the ring?(And I assume CC were unwilling to divulge the name of their driveshaft supplier?)JV Link to comment Share on other sites More sharing options...
ScottR400D Posted July 12, 2020 Share Posted July 12, 2020 Give me a minute. I have my shafts on the bench. Link to comment Share on other sites More sharing options...
ScottR400D Posted July 12, 2020 Share Posted July 12, 2020 Well, unfortunately that’s a lot harder than I thought. My vernier won’t span that diameter. It’s wide enough but the measuring surfaces aren’t long enough to reach to the max diameter with the shaft assembled. The best I got was about 93mm. I also count 43 teeth with a pitch of 7.0mm which calculates to 301mm circumference, 95.8mm. Sorry can't be more precise. If I think of a better way to measure I’ll be back.

Tuck2020 Posted July 12, 2020 Author Share Posted July 12, 2020 Thanks Scott, your efforts are appreciated. When I spoke to Chris at Redline he said they weren't easy to measure!I've given Darren at Caterham a nudge this week, but still haven't had a response, I guess they would rather sell me a new driveshaft for several hundred quid...

Tuck2020 Posted July 12, 2020 Author Share Posted July 12, 2020 Apologies John, 72mm was as close as Chris could get for internal bore size. Link to comment Share on other sites More sharing options...
ScottR400D Posted July 12, 2020 Share Posted July 12, 2020 If you go on the shop site, select a driveshaft product and then click on ‘ask an expert’ you can ask a question. I’ve done it a few times and always had an answer, though with mixed results in terms of satisfaction. Link to comment Share on other sites More sharing options...
