reliable source of info
Finally got my tranny tear down pix posted to my website, there are a whole bunch of 'em, as I wanted to record how it is so I can get 'er back together again in the right order....
Here's some of them:
This tranny was built sometime in the 80's...
When I split 'er open, this was what I found, with lots of loose teeth in the bottom of the case, and many small pieces in some of the bearings....
Pulled the mainshaft out first and took it apart. The main bearings at the front and back had metal in them, and were noisy after I cleaned them thoroughly and spun them by hand, so replaced them. My local bearing house had them in stock.
The gears, other than 2nd, all look great, as do the synchronizer rings (brass) and the needle bearings under each mainshaft gear....
Each slider, and the receiver it slides on, has three spring loaded detent keys that give a positive feel to the neutral position for each slider, they were broken in this 5-rev slider above, and in the 3-4 slider. The keys in the 1-2 slider were good. I don't know why these broke.
Here's the 3-4 slider and the broken keys. Later I found the missing pieces mixed in with all the broken teeth....
Here's all the mainshaft pieces laid out in order so I can put 'em back together again....
Then washed up the countershaft and started taking it apart....
The main bearings on both ends, and that needle bearing in the middle, are noisy, so are being replaced. Again, I was able to obtain them locally....
Then I had to pull the reverse idler gear stub shaft and check it all out....
It's all good, but decided to replace those needle bearings anyway, just to be safe....
Richmond Gear said that I have the later model Doug Nash 4+1 (from the serial # stamped on the case), and a pair of 2nd gears are on the way from them....
It actually was fun taking this apart. Hope I can say that again when I get it all back together....
Aloha,
Willy
