mleadbeater Posted February 14, 2014 Report Share Posted February 14, 2014 Just tried fitting the prop shaft to the TR2 which I am finishing off, having bought it part restored, and find it is about 20mm too short. As far as I know the axle is a later Girling, and the box is standard 3 sincro. Any ideas? Cheers Mike Quote Link to post Share on other sites
vivdownunder Posted February 14, 2014 Report Share Posted February 14, 2014 Lockheed or Girling diff/3 or 4 synchro/fixed axle or IRS doesn't matter as the prop shaft was the same item right through. If the drive train and diff are correctly positioned and the prop shaft spline is sliding as intended, looks like a wrong prop shaft. Viv Quote Link to post Share on other sites
Lebro Posted February 14, 2014 Report Share Posted February 14, 2014 Obvious question, but is the shaft at full length, or can it be pulled out further ? I agree with above, Lockheed or Girling axle would make no differance. Bob. Quote Link to post Share on other sites

mleadbeater Posted February 14, 2014 Author Report Share Posted February 14, 2014 Thanks Viv, Bob, for replies. Shaft in good order, splines fully extended freely. Flanges correct bothe ends. Do you have the extended length?, Maybe axle too far back, any dimensions to check please. Eg spring end to axle centre? Cheers Mike Quote Link to post Share on other sites
vivdownunder Posted February 15, 2014 Report Share Posted February 15, 2014 In the old scale, distance static laden from centre of the front spring eye to centre of centrebolt was 18.63" (473.20 mm) plus or minus .063" (1.6 mm). The cerntrebolt locates the axle via the U Bolt bottom plate. Interesting when taking a quick measure under my car, that distance looks to be only 450mm. So a 23 mm difference somewhere which roughly equates to your problem, but I haven't figured out what's wrong. Viv Quote Link to post Share on other sites
Bob Smith Posted February 15, 2014 Report Share Posted February 15, 2014 Mike, I have a number of spare propshafts if you can't solve your problem. Quote Link to post Share on other sites
Kiwifrog Posted February 15, 2014 Report Share Posted February 15, 2014 If you purchased the car partially restored it could have the wrong rear springs meaning the mounting pin for the diff is in the wrong place, or even the springs mounted backwards which would be hard as the larger spring eye goes to the front.

Dave Larnder Posted February 15, 2014 Report Share Posted February 15, 2014 Mike When I put my prop shaft in after the chassis build up, I found the shaft was absolutely fully extended to bolt up to the O/D., so I turned up a 10mm thick spacer and put it in between them and after 5 years I have had no trouble at all. BTW. the rear wheels are exactly in the middle of the rear wheelarches as they should be, so i know the axle is in it´s correct place. Dave Quote Link to post Share on other sites
peter clarke Posted February 16, 2014 Report Share Posted February 16, 2014 Measured off the car shaft length flange to flange when "compressed" is 27 3/4 inches Quote Link to post Share on other sites
mleadbeater Posted February 19, 2014 Author Report Share Posted February 19, 2014 Gentlemen, Many thanks for all your comments, have made a cast-iron spacer approx 22mm thick for the front flange and fitted longer cap-head bolts. Spring length seems ok at around 475mm, unladen, so still a puzzle. Cheers Mike Quote Link to post Share on other sites
Lebro Posted February 20, 2014 Report Share Posted February 20, 2014 Just make sure that the shaft is stillperfectly in line with the gbox flange - any slight missalignment will cause harsh vibration, & short life of UJ's. Bob. Quote Link to post Share on other sites
mleadbeater Posted February 21, 2014 Author Report Share Posted February 21, 2014 Cheers Bob, yes, I made the male & female spigots on the spacer a good fit so should be lined up ok. Just a final thought, could the engine be mounted a little forward somehow? Mike Quote Link to post Share on other sites
Lebro Posted February 21, 2014 Report Share Posted February 21, 2014 I think you would have noticed if it was when you fitted the gearbox mounting - did you have to struggle to get the bolts into the chassis? If not, then the gearbox is in the right place. Bob. Quote Link to post Share on other sites
mleadbeater Posted February 23, 2014 Author Report Share Posted February 23, 2014 Bob, the car came with box and engine already fitted. Engine / box must be fitted correctly as bellhousing flange is just ( 1/2" or so ) forward of bulkhead. Can anyone tell me the fully extended propshaft length please?

HeswallTR3 Posted February 27, 2014 Report Share Posted February 27, 2014 had the same problem a few years ago, took several cups of coffee until i realised that the shaft was telescopic..........never told anyone until now Quote Link to post Share on other sites
mleadbeater Posted March 8, 2014 Author Report Share Posted March 8, 2014 Mike, I have a number of spare propshafts if you can't solve your problem. Bob, Can I take you up on this offer for a spare shaft, mine is definately too short by at least an inch. I am in York so could call if convenient. What do you want for one? How do I contact you best, e mail or phone? Cheers Mike Quote Link to post Share on other sites
Bob Smith Posted March 9, 2014 Report Share Posted March 9, 2014 Mike, Easiest way is to send a PM & then we'll go from there! Propshaft will not be expensive. Quote Link to post Share on other sites
