ronhatch Posted July 21, 2021 Report Share Posted July 21, 2021 Hi all, I was tootling along yesterday, top down, cap on (bald head), enjoying the sunshine when I heard an ominous rumble. A few months ago the bolts on the propshaft had come loose and it sounded very similar to that. I put it up on the stands and checked but the bolts were tight. I then put the car in gear and turned the rear wheel and heard a slight noise from the gearbox, it was the same noise throughout all the gears so I assume it is wear on the main shaft ? The car drives well apart from this noise any ideas ? Regards Ron Quote Link to post Share on other sites
Lebro Posted July 21, 2021 Report Share Posted July 21, 2021 Sounds like gearbox bearings, either the big ones front or back, or the layshaft roller bearings Bob. Quote Link to post Share on other sites

ronhatch Posted July 22, 2021 Author Report Share Posted July 22, 2021 Are the bearings easy to change ? Quote Link to post Share on other sites
MichaelH Posted July 22, 2021 Report Share Posted July 22, 2021 Easy when you get there! but gearbox out, overdrive off and strip it down first- so a lot of work. Very good instructions from Pete Cox article in Technicalities or look at rebuilding gearboxes on Buckeye Triumph (on the net) or farm it out to someone like Pete Cox Good luck Quote Link to post Share on other sites

Lebro Posted July 22, 2021 Report Share Posted July 22, 2021 No, they are not easy ! the main (big) bearings are a very tight fit on the I/P & main shafts, getting them off, & new ones on is a pain, & you need to be very careful not to damage the new bearing when you fit them, & then when you re-fit the main shaft to the box. See my recent article: Gearbox strip & rebuild.pdf Bob Quote Link to post Share on other sites
John L Posted July 22, 2021 Report Share Posted July 22, 2021 If you do go for changing them make sure you get some good quality ones, I think Moss has 2 versions, cheap and more expensive, go for the more expensive ones! John Quote Link to post Share on other sites
