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) |

I now know how new teeth should look like, but is there an indication/threshold when they are worn out. Is there any measurement method for indication ore just experience.
Let's talk a lite bit about the function of the teeth. As far as I know the slider shoult only slide ove the syncro ring if the rotating speed of the cogs are the same. Are the teeth edgy the shift will be easy are the worn(rounded,flat) the shift will snag. So the importent part is always the syncro ring also if the teeths are a litte bit flat..ore? So the grinding noise is forced by worn syncro rings and will lead to flat teeth. |
