Ken Bradley Posted December 6, 2015 Report Share Posted December 6, 2015 Help! I am very new to Triumph workings and on a very steep learning curve. I've rebuilt the back end of a Spitfire 1500, exchange diff, new drive shafts, bearings and UJ's. No great problems, other than the trunnions! How tight are they supposed to be? As soon as I get anywhere near the stated torque (48 ft/lbs) the "squeeze" on the vertical link is such that the trunnion is pinched so tight it is difficult to move. Is that as it should be? If fitted that tight they will be acting as another suspension damper. Please reassure me I've not gone mad. Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 6, 2015 Report Share Posted December 6, 2015 The trunnion bushes should have a tube to set the clamped up thickness it should be about the same length as the bushes so you tighten on the tube not the bush they should waggle pivot relatively easily are you using std plastic or poly ? Were there any problems fitting the water shields and their o rings ?? Link to comment Share on other sites More sharing options...
Ken Bradley Posted December 6, 2015 Author Report Share Posted December 6, 2015 I'm using standard plastic but the tube provided is nowhere near the width of the bushes and the washers etc. You appear to have identified my problem, many thanks for the information. I feel a call to the suppliers coming on!!!! Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 7, 2015 Report Share Posted December 7, 2015 recall that's happened before, when front and rear tubes get mispacked let us know how this progresses Pete Link to comment Share on other sites More sharing options...
Ken Bradley Posted December 7, 2015 Author Report Share Posted December 7, 2015 Didn't get much joy from the supplier, other than the to be expected "this has never happened before, we've sold thousands of them". I have overcome the problem, I think, by putting what I considered to be an enormous bend in the vertical link. I not talking just straining it to insert the trunnion, rather I've "bent it"! Also, I've not used anything like the stated torque. 48 ft/lbs seems to me to be a hell of a lot, to the point where it started to overcome the bend I'd put in the sides of the link. All seems to function okay. The various washers and the "O" rings are in place, but it still does not alter the fact that the tubes do not completely fill the bushes! Comments please, Ken.

Pete Lewis Posted December 7, 2015 Report Share Posted December 7, 2015 The trouble with that is the link and trunion are not fully supported as the bolt is effectively now 'loose' tomallow some degree of swivel. Its quite important that the tube is solidly clamped between the legs of the upright and the through bolt is up to torque pete Link to comment Share on other sites More sharing options...
Ken Bradley Posted December 8, 2015 Author Report Share Posted December 8, 2015 Back to drawing board, and another supplier! Thanks for the information. Link to comment Share on other sites More sharing options...
Ben Caswell Posted December 8, 2015 Report Share Posted December 8, 2015 Check the length of the new sleeve tubes against the old originals you shouldn't have to distort the upright. Link to comment Share on other sites More sharing options...
Ken Bradley Posted December 9, 2015 Author Report Share Posted December 9, 2015 Being the tidy soul that I am, and with total faith in the new kit, I had thrown the old bits away when I dismantled everything! Link to comment Share on other sites More sharing options...
