Mollysdad Posted March 4, 2016 Share Posted March 4, 2016 13/60 non-overdrive strap type propshaft.Could someone please confirm the strap end goes next to the gearbox? Can't for the life of me remember or find a picture from when I took it apart! Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted March 4, 2016 Share Posted March 4, 2016 Strap at the gearbox end I believe. Quote Link to comment Share on other sites More sharing options...
oldmetalhead82 Posted March 5, 2016 Share Posted March 5, 2016 My 1200 has a strap type and the strap end is at the diff, the Haynes manual also states at the diff. Quote Link to comment Share on other sites More sharing options...
Mollysdad Posted March 5, 2016 Author Share Posted March 5, 2016 Thanks, I've just found a picture in the original workshop manual showing it at the diff end. Good job I checked! Quote Link to comment Share on other sites More sharing options...
Casper Posted March 5, 2016 Share Posted March 5, 2016 Quoted from Mollysdad Good job I checked! This question raises itself occasionally. My recollection is that the general consensus is that it doesn't make any real difference.C. Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted March 5, 2016 Share Posted March 5, 2016 Oddly the Canley's Website appears to show the strap at the front, but I only say that as it 'appears', which I took to be 'in car line' so my apologies for that. Quote Link to comment Share on other sites More sharing options...
Dogsbody47uk Posted March 6, 2016 Share Posted March 6, 2016 My manual puts it at the rear. Cheers, Dave. Ps. Throw it away and get a sliding spline type from Canley Classics or DaveMac props! Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted March 6, 2016 Share Posted March 6, 2016 Quoted from Dogsbody47uk My manual puts it at the rear. Cheers, Dave. Ps. Throw it away and get a sliding spline type from Canley Classics or DaveMac props! Amen to that. Those strap drive horrors are the devils work.Nick Quote Link to comment Share on other sites More sharing options...
herald948 Posted March 7, 2016 Share Posted March 7, 2016 They're not really all THAT bad...unless you find one where someone removed presumably broken straps and bolted it together SOLID. (Yeah, really! ) Quote Link to comment Share on other sites More sharing options...
heraldcoupe Posted March 7, 2016 Share Posted March 7, 2016 Quoted from herald948 They're not really all THAT bad...unless you find one where someone removed presumably broken straps and bolted it together SOLID. (Yeah, really! ) This is what John Kipping used to recommend, and having had a few done like this by their previous owners, I never had any problems with how they behaved in use.I always swap out strap-drive propshafts for solid or splined (if I have one) at the first opportunity. Metal fatigue in the straps has been a real problem in my experience,Cheers,Bill. Quote Link to comment Share on other sites More sharing options...
marktheherald Posted March 7, 2016 Share Posted March 7, 2016 I recall dismantling a strap type shaft to find that the O-ring (part 4 on the Canley diagram) was non existent and had let water work it's way in with subsequent corrosion and wear... Swapped out to splined Vitesse item when I fitted overdrive. Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted March 7, 2016 Share Posted March 7, 2016 What was the thought (if there was any) at Canley by fitting straps in the shafts? Splined or solid is standard fair, just wondering if there was a reason, or something they were trying to eliminate by fitting straps?

Clive Posted March 7, 2016 Share Posted March 7, 2016 I think it was to allow a tiny bit of movement/length change/ease of fitting. I really can't think of any other reason. Rubbish idea...... Quote Link to comment Share on other sites More sharing options...
Richard B Posted March 7, 2016 Share Posted March 7, 2016 Quoted from cliftyhanger I really can't think of any other reason. and dampen transmission vibration? 🤔 Quote Link to comment Share on other sites More sharing options...
RobPearce Posted March 7, 2016 Share Posted March 7, 2016 Having a small amount of plunge in the prop will ease fitting and also improve NVH, because it helps decouple the engine/gearbox from the diff/chassis. That's why the sliding splines were used, but they're expensive to make. The strap type prop is cheaper. It may, also, be marginally better at absorbing torsional vibration but I doubt that's significant. Quote Link to comment Share on other sites More sharing options...
