I knew first and second gear syncros were in bad shape. Third is not bad, reverse has some issues.
First problem no gaskets, it is sealed with rtv, I have know idea what the preload and backlash for the ring and pinion is at his point. I guess I need to check the both. Next I notice the the reverse idler gear thrust washer is badly scored and worn. Thinking to myself I think we are missing a part. Bearings are just extra parts, you don't need those. /s The reverse idler gear does not look badly worn from the thrust washer. However the teeth look pretty beat-up. I think I might need to find a replacement reverse idler gear. I think without the bearing between the reverse idler gear and thrust washer, it was sometime touching the first / reverse shift sleeve. Some syncro rings have the expected wear, but this one has groove in it. it seems to be a manufacturing defect. Some of the brake bands show wear, i'm not sure if that is normal. Some of my syncro hubs look more like igloos than peaked roofs. |

Finding the a good used replacement thrust washer wasn't to bad. I had to email around to find a good reverse idler gear. Porsche still makes the bearing.
Some good news on gaskets, the sets have three gasket thicknesses again. Since mine was rebuilt with RTV and I did not have and ring and pinion noise. I am going to try it with the thinest one. Since I don't have the tool to measure the pinion depth, I am attempting to check the gear patterns. I'm having no luck finding gearing marking compound or Prussia blue locally. I ordered gear marking compound what is delayed a week. I tried white lithium grease. It seems to be even across the whole tooth. Maybe that is normal and gears with a 100k on them. I was able to measure backlash, well enough to have some comfort level, that is still in spec. |
