Hello guys,
I've bought my car without any test drive because it was unsed many years. Now my transmission is on my todo list. I already opened the case to inspect the 1st gear. I saw a syncro ring which seems to be less used but the dog teeth and the slider speeks other words. My impression.. I have to change slider, dog teeth and syncro. I added some pictures, who can distinguish between poo parts and reusable ones. Attached thumbnail(s) |

Georg,
Regarding the bore for the roller bearing, I have remove a number of those bearing races. They are not very tight, but they are also not finger loose either. If you must have that case (it is an original case for the car and you want to keep it), then I am sure there are options. I know that Loctite makes products for this situation (I think it is Loctite 640 and/or 648), but I have not tried those products so I can't vouch for their effectiveness. At a minimum I expect that once used, it would be very difficult to remove the outer race in the future. If it was me, I would try to source a new case. I don't know how easy they are for you to obtain, but in fact, it might be more cost effective for you to source a complete core transmission and then hope for the best that it may be a better candidate for rebuild. It may have a good ring and pinion to start with and you wouldn't have to mess with trying to set pinion depth, backlash, pre-load and your current transmission already looks to have good examples of the commonly worn items (such as a 1st/Reverse slider). Good luck and I hope it all works out. Continue to post if you have more questions. Richard |
