rvwp Posted September 26, 2020 Report Share Posted September 26, 2020 Hi Guys, Need to replace the bump stops on the body of my TR4A resto project nearing completion. Yeh . Looking at what was on the car, certainly since 1982 when it was last on the road, the bump stop seems to a have a alloy spacer and a longer stud than the replacement bump purchased from Moss? The Moss catalogue makes no reference to a spacer. Is this original or added as a aftermarket item? Thasnks Rich Quote Link to post Share on other sites
Geko Posted September 26, 2020 Report Share Posted September 26, 2020 (edited) You asked the same question a while ago and the consensus was that it is original indeed - on my car it certainly is. I had the same issue with MOSS who sent me bump stop with the short stud (23 mm), so had to ask them to resend the same with the long stud.

stuart Posted September 26, 2020 Report Share Posted September 26, 2020 That is original. but only listed in the catalogue as for a solid axle car which also has this fitted. Stuart. Quote Link to post Share on other sites
RogerH Posted September 26, 2020 Report Share Posted September 26, 2020 Hi Rich, My 4A also has a spacer but mine is wedge shaped. Roger Quote Link to post Share on other sites
rvwp Posted September 26, 2020 Author Report Share Posted September 26, 2020 Ok, sorry can't remember asking before?. Will check again with moss as I need a spacer and longer stud bump stop for the other side. Thanks Rich Quote Link to post Share on other sites
rvwp Posted September 26, 2020 Author Report Share Posted September 26, 2020 Looks like the spacer is NCA, so will have to get on the lathe and make one out of alloy. Rich Quote Link to post Share on other sites
BlueTR3A-5EKT Posted September 26, 2020 Report Share Posted September 26, 2020 From memory - 140290 bump stop should have the longer thread (over an inch of thread) 136758 is smaller diameter and has a shorter thread (about 1/2 inch) Peter W Quote Link to post Share on other sites
Z320 Posted September 26, 2020 Report Share Posted September 26, 2020 I asked something about this some time ago, mine is like Roger's. Quote Link to post Share on other sites
Tr4aJim Posted September 27, 2020 Report Share Posted September 27, 2020 In the Stanpart catalogue the spacer is only listed for the solid axle suspension (plate W). It’s not listed at all for the IRS (plate V). Jim Quote Link to post Share on other sites
rvwp Posted September 27, 2020 Author Report Share Posted September 27, 2020 Hi Peter, Bump stop 149240 seems to be shown in the Moss cat for both IRS and solid axle TR4A'a in both the body and the chassis fixing positions. It has approx 1 inch of 3/8 UNF thread. However the spacer is only shown for the solid axle on the body together with 149240 but this is not long enough to go through the approx 1 inch spacer? Clearly the spacer was used on the TR4A IRS as indicated by my car and others. Thought I would make a spacer if I can find some alloy of the right size, struggling at the moment, but where to get the correct length thread Bump stop? .

keith1948 Posted September 27, 2020 Report Share Posted September 27, 2020 Just an idea but make an alloy spacer. Put a threaded hole through it. Screw bump stop into threaded hole. Screw bit of threaded rod into other side of threaded hole and use that to attach to car. Use lock tight as well. Keith Quote Link to post Share on other sites

Regards Rich You buy the one listed for the solid axle car. They must be around as Ive bought them for mine years ago although the part numbers seem to be quoted as being the same now Stuart.

Hi Stuart you misunderstood what I was saying. If thread on bump stop is too short through spacer then make another spacer with a threaded hole so you can screw bump stop into one side and threaded rod into other side. As I understand it the spacer simply has a hole through it (not threaded). You could also helicoil the spacer to take the bump stop thread and again put an extra bit of threaded rod the other side to fit to the body. Keith Quote Link to post Share on other sites
rvwp Posted September 28, 2020 Author Report Share Posted September 28, 2020 Hi Guys, I already have 2 of the Moss 149240 purchased some time ago, both with 1 inch long thread. Pretty sure if I ordered again using the solid axle 149240 I'd end up with 3 . The way to go is as suggested make a spacer with a 3/8 UNF tapped thread through the middle, and reduce the thread length of the bump stop to 1/2 inch, screw in one side of the spacer with a length of 3/8 UNF stud protruding from the other side to screw into the body.

Thasnks Rich Is there a chance the brake line can get hit by the bump stop, or is it just the angle of the photo? Quote Link to post Share on other sites

qkingston Posted October 1, 2020 Report Share Posted October 1, 2020 so just now and again the gods smile on you, after reading this thread I went back to my boxes of junk bits and found....the 2 alloy spacers! I'd forgotten what they were for! David Quote Link to post Share on other sites
rvwp Posted October 8, 2020 Author Report Share Posted October 8, 2020 Hi Guys, Despite searching through all my 'come in hand boxes (have I really had that part for 50 years!)', I cannot fine a lump of alluminium approx 2 inch dia x 1 inch long from which I can machine up a new spacer. Anybody have such a lump or know of a source? Cheers Rich Quote Link to post Share on other sites

rvwp Posted October 9, 2020 Author Report Share Posted October 9, 2020 Thanks guys for the info. I have been looking at e-bay and yes there are some possible sources of 2" bar our there, but, not being mean, but what seems like a reasonable price always is too much and becomes so expensive when adding postage etc. In any event I am trying to reduce having extra 'stuff' in my workshop/life. It's time to start decluttering . No rush, car won't be on the road now until next spring anyway, something will turn up. Thanks anyway Rich Quote Link to post Share on other sites
