However they do list stops for a Tr6 (156111). Will these work on my car? Jim They will but they will be the centre drilled ones. Stuart. Quote Link to post Share on other sites

Lebro Posted April 19, 2019 Report Share Posted April 19, 2019 Easy enough to make a pair up, I can do you a drawing if you like (of TR3 ones, which should be the same, ie eccentric hole.) Bob. Quote Link to post Share on other sites
Tr4aJim Posted April 19, 2019 Author Report Share Posted April 19, 2019 Bob, thank you, but unfortunately I do not have any machining equipment (or skill). Also based on what Stuart and Tim mentioned, (and the remaining stop I have), it seems like Triumph began abandoning the eccentric stop with the Tr4a by giving it a subtle offset, and no offset at all with the Tr6. However I will be careful to align the trunnion bolt/nut during reassembly, as Stuart described. Jim Quote Link to post Share on other sites

Tr4aJim Posted April 20, 2019 Author Report Share Posted April 20, 2019 Just an interesting footnote - Moss US also lists the TR4a stop as NLS. Yet Moss UK does list the part. However the Moss UK part number is 156111, which is the Tr6 stop. Rimmers and Revington also lists the stop as part 156111. I guess the stop originally fitted to the Tr4a (142403) is no longer produced. Jim Quote Link to post Share on other sites

I had one missing and a local engineer made me one. Stuart. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted April 20, 2019 Report Share Posted April 20, 2019 156111 are the concentric type - non adjustable - fit and forget (?) Peter W Quote Link to post Share on other sites

Peter W +1 excentric is 50% safety, only one don't work, concentric is 200% safety, one alone can do the job, lose one and be happy anyway.

Bob. The TR4A onwards ones are at least twice the height as side screen car lock stops. Peter W Quote Link to post Share on other sites
