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) |

There is another alternative to changing cases. The original /6 box I just rebuilt has both bearing races in the case loose. Since I use good used parts in my rebuilds where ever I can, I measured all of my stock and found that there is just enough variance in outer race diameter to take up that slop. The end result was a better bearing with appropriate interference with the case. If you measure the outer race of the loose bearing, I or someone else may have a larger one for you. If you go the lock-tite route, I would use a very good bearing or a new one to ensure you do not need to remove it anytime soon. You should get another 30-40 years out of the bearing that way.
As for swapping gears, that is easy. You just measure the thickness of the gears (in the center), compare them to the thickness of the ones you are swapping off (you only need to measure the pinion shaft), and then adjust for the difference either at the gaskets between the intermediate plate and case if you can, or the shims on the pinion itself. |
