    Spitfire Drive Shafts

    Hello All I thought I had better start a new thread not clog the other one up I emailed the suppliers today and recieved 2 replies all as below Hello Sirs I purchased two Triumph Spitfire Drive shafts from you on the 04/07/2017 Part No 155928 One of these drive shafts started to make a soft crunching/squeaking noise at about 500 miles but I could not see at the time any fault so I thought it may be a faulty universal joint and carried on using the car for the rest of the summer. Over the winter months I did a bit more investigating into the noise and found that the yoke had come loose on the drive shaft and all that stopped it coming out of engagement was a ROLL PIN - which was breaking up!!! I have also checked the second shaft, which is still fitted, to the car and this is also showing slight signs of movement having now covered 5,000 road miles. Triumph fitted a solid pin in this position and we assume their Engineers knew what they were doing as this is a Safety feature and also, on the OE shaft, the yoke is a press fit onto the shaft requiring several tons of pressure to fit it. As the combination of too loose a fit of the spline and a wholly inadequate pinning method can cause the shaft to pull right out, resulting in the collapse of the rear suspension (and has done so on at least one occasion I am aware of - see link below), I think you need to advise your suppliers of the potential failures of these parts as it could lead to at best badly damaged cars and at worst loss of life with all claims that will bring! You may also wish to advise your colleagues in the retail sector of this safety risk. I have attached photos showing the roll pin(as it came out) that just pushed out and the fretting of the shaft where it had been moving in the yoke. This drive shaft had only covered 1800 miles You may also like to read this report of one of these type that failed (I am not saying you supplied these but they look like they are of the same type I think?) Roger Greening 14/08/2018 http://forum.tssc.org.uk/topic/3850-reproduction-herald-driveshafts/ Hi Roger, Thank you very much for informing us of this, we have not had any other comments as yet. I will forward your email to the supplier and let you know what they say. Regards, Paul. Hi Roger, The initial feedback from our supplier is that they have not seen this problem previously. They are going to examine a couple of shafts in their workshops to assess how securely the yoke is attached to the shaft. I will let you know. Regards, Paul. So I will wait for their findings, perhaps I was unlucky and was supplied the only faulty 2 ! Roger

    Hello Nick Yes top one OE spec I think I had to saw the yoke off as I could not get the pin out I have had another look at both shafts the OE one has 24 splines and is 1.034" (about 0.003" over 1 1/32") sounds about right for an interence fit! and the main shaft looks like hot drawn bar(rough) 1.044" Dia The pattern one is 1.110" = 28 mm Dia and 25 splines and they are deeper the whole lenght of the shaft has been turned down to 1.044"? So was it hot rolled or bright drawn bar? I tried the file test on both and I can just mark the pattern one but not the OE one (needle file) Roger

    Hello All I have driven the roll pin out of the other yoke(not very tight) I tried to press one out of and old drive shaft with the hydraulic press with no luck. Looking at the red rust on it I think the other drive shaft may be coming loose as the rust is the same as failed one! I have fitted a 6 mm 8.8 bolt in it for now that has got to be better than a roll pin? Roger

    Hello Nick You are correct. I have had another look at the shaft this morning and the spline end does not look to clever to me either! what do you think? Would you mind if I pm,d you with a copy of the complaint I am going to prepare and send to the suppliers? I want to state all our concourns but not be Confrontational etc Roger

    Hello Nick It is a nice? sliding fit! you can see the fretting on the splines and in the hub! it was a disaster waiting to happen? I have posted them on the TSSC forum http://forum.tssc.org.uk/topic/3531-drive-shafts/ I will send the photos to the supplier but unfortunatly I bought them last July(I should have done it earlier!) just to make them aware on the risks they present and risk of prosecution if someone gets really hurt or killed? Roger Ps those hair pin bends we were going around and a lot without any safety rails of any sort and a nice big drops !

    Hello All I have just frightened the S***t out of myself ! I thought I would try and press the ROLL PIN out of the Kn****D shaft Well to be honest I think I could have pushed it out by hand! and this is how it came out!!!!!!!!!!!!!!!!!!!!!!!!!!!! The photos show the grim picture? Roger ps it is 6mm I am thinking I will jack the car up tomorrow and see if I can push the other one out and fit a high tensile bolt for now for peace of mind! Those expensive ones are looking good value now?

    Hello All Shall I be the guinea pig? its only money! and I am getting a bit P****ed off with taking it all apart etc Plus I am a sucker for new shinney parts! Better not tell the Memsihab! I think these old cars could be the death of me(still worse ways to go?) Roger ps now do I fit the lower ratio differetial at the same time or look for another 3.65 one?(I have put all new bearings in it!) It took me a few hours to get the new computer(this one)to talk to the microsquirt!!!!!! I got there in the end but do not ask how(smoke and mirrors) pps I am lead to believe the uj,s are all made in somewhere foreign ? now so we need NOS?

    Hello Nick Now I am not sure which is worse old Triumph stressed driveshafts that may or may not snap! or repro ones that yoke comes loose and is only held on by a ROLLPIN! The ones at £1000 start to look more apealing! (the thought of one going when we were going or coming down some of the Pyrenees passes make the blood run cold)I know I have to go some time but I do not want to rush the day on!(and it is only money!)

    Hello Nick You are right but I feel it will be like banging my head against a brick wall! Yes I may get my money back but they will keep selling this CRAP (bad language again but it does make me mad) because there is nothing else! Plus we are all guilty up to a point as we want cheapish spares and most cars do no mileage so it is not problem! Just my opinion ! Roger

    Hello Nick Yes I have just looked at my failed one (1800miles and it was creaking after about 200 miles!) the other has now done 5000 miles! And yes it is a ROLL PIN!!!!!!!! (what a load of crap) please excuse the language but it makes me mad Now I am worried about the other one! I will be looking for good old ones as a spare or to change? I suppose they are ok for the polishing brigade but not me and they offend the Engineer in me! Still they did well to get 8000 miles on bad roads with them and bought in good faith! Roger
