About the inner milky nylon polyamide bush, Moss sells the black POM version less than half price of the white nylon polyamide bushing so I thought that was inferior quality. The rubber sealing rings I replace with the polyurethane version. Also the rubber seal rings on the outer end will be replaced with the polyurethane version. What do you mean with "..Argro.."? Thanks again, Erik PS: I use the spring compression tool made by Z320, top job! My experience with the black nylatron POM bushes from Moss is that they require 'sizing' to the steel bush once they are installed in the wishbone arm. They are probably cheaper as they have been in stock for so long, perhaps since Triumph Tune ran as a separate business alongside Cox and Buckles Spares.

Peter W I just discovered that the standard nylon bushes part #110696 and part 115 on this drawing: https://www.moss-europe.co.uk/front-suspension-tr2-4-1953-65.html also needs reaming. Edit: wrong info, fitting is fine, there was some dirt when trying the new nylon bushes Edited July 23, 2021 by earckens correction, wrong info Quote Link to post Share on other sites

I'd clean them up to see if the bronze layer has worn through (if it has they're scrap) and try the new trunnion spindle in there with just some light oil to test them for size. If they're not sloppy I'd re use them. I wouldn't use anything other than the standard bushes in the lower inner as they exhibit far less flex than poly-bushes. The lower inners take the majority of the load and poly bushes let the assembly flex quite a bit especially under hard braking. I've used the nylon lower inners on the top fulcrums too for better location but unlike some I do prefer a bit of handling sharpness over a smooth ride. Just discovered that the trunnion pins show signs of wear and grooves (photo's). Is there any particularities I have to keep in mind when replacing the trunnions (ie. number of turns when screwing out identical to number of turns when screwing new one in,..)?

Drewmotty Posted July 23, 2021 Report Share Posted July 23, 2021 I screw them in as far as they’ll go and still allow full lock with the lock stop fitted. those spindles are well beyond their best. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted July 23, 2021 Report Share Posted July 23, 2021 (edited) Coo.! real TR4 with thin washers to support the grease seals. PS Yes the pins look very worn. Don't chuck the trunions tho if they are a good fit on the V posts. New pins may turn up. We used to sell them as a spare part 40 years ago.

Peter W What are "V-posts"? What do you suggest I do with these trunnions? I think they are original, so for the time being maybe replace them with new ones? And what with the current ones? Thank you for the compliment on the thin washers.. the more I work on this car the more I discover about it. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted July 23, 2021 Report Share Posted July 23, 2021 (edited) V post is the vertical post that the trunion screws onto. I’d put the old trunnions in a box or somewhere I could find them in years to come in the garage workshop. Look in the box every 6 months or so to remind you what is the. Perhaps a label…TR 4 …needs pins - thread to vertical post good. Pete W Edited July 23, 2021 by BlueTR3A-5EKT Quote Link to post Share on other sites
