Menno van Rij Posted February 10, 2008 Report Share Posted February 10, 2008 Hi all, Nothing much happened since my last report. The body is still in the paintshop and the chassis is still on it's wheels in the workshop. Painting is in progress as stated last posting. I found on the 4/4A part of the forum a topic about a rear axle. And then there was this in one of the answers: There should be a third central bump stop which attatches to the underside of the body tub to stop the diff coming into contact with the body. From memory I think it would be difficult to fit once body and axle are reattatched to chassis so worth ensuring it is attatched to the body first. Well, my car came without that third bump stop... Is there a third bump stop on a TR3A rear axle? How does it look? Are there any pictures around? The bump stops on my car came from the Dutch supplier of Revington parts (I.S. International). I find this firm very accurate. So, therefore I can not believe they've forgotten send me the third stop. Can you give me info on this? Menno Quote Link to post Share on other sites

Menno [/quote Hello Menno, my 1960 TR3A was an original unmodified car, no third bumpstop, only the 2 outer ones I believe, that the chassis hoops control the upward axle movement. regards Peter.

Don Elliott Posted February 10, 2008 Report Share Posted February 10, 2008 Menno - Peter is correct. Mine came with two (similar to your blue ones - but black) and there are the two painted steel hoops above to act as the other "stop" but I don't know when they would ever need to be used. The two rubber stops on the axle shaft casing are stopped when the wheel suddenly drops into a deep hole and the axle would hit the top of the frame if it were not for these rubber "cushions".

Trevor S Posted February 11, 2008 Report Share Posted February 11, 2008 Hi Menno, It was me who wrote the quote in the TR4 section to which you are referring. TR4s definitely have a third central bumpstop over the differential part of the axle . This stop is attatched to the underside of the body. They don't appear to have been fitted on side screen cars, and when dismantling my TR2 for restoration I never came across one. I can only assume that the different shape of the lower body tub on the TR4 was thought to require one. Regards Trevor. Quote Link to post Share on other sites
Menno van Rij Posted February 11, 2008 Author Report Share Posted February 11, 2008 Hi all, Thank you for your accurate responses! Saves me a lot of trouble. The car is nearly back together again (chassis and body-wise, that is), so the last thing I wanted to do was looking for that hard-to-find (...) bump stop.

fingoon Posted February 13, 2008 Report Share Posted February 13, 2008 so the last thing I wanted to do was looking for that hard-to-find (...) bump stop. When I started on My 3A I found that it had obviously been entered into some sort of jumping competition sometime in it's life. The diff bump stop hoops were missing.. There was a large hole in the boot floor where the diff breather had penetrated the floor. The boot floor had been disconnected from the inner guards on both sides by the impact of the diff from underneath with a split of about 400mm on each side and large bow in the inner guard. A 200mm long split in the front LH suspension tower was probably the result of the same landing. My conclusion is that bump stops fitted with the correct hoops are obviously useful. Some more enthusiastically than others.. Unfortunately house building has overtaken TR building for most of this year so my project has slowed. cheers Rob Quote Link to post Share on other sites
vivdownunder Posted February 15, 2008 Report Share Posted February 15, 2008 Get back into it Rob..... we want to see more than a rolling chassis at this year's National Rally at Thredbo. Rather than taking out the "Restoration of the Year" trophy again, why not toss the body back on during your mild Queensland winter and have a crack at the Concours. Cya, Viv.
