Man do I have spares in my stash, this is going to sound sick but syncro's are only like $15- $20 each, but I have over 30 NOS sets. Plus many new gears and hubs.
Doc found an NOS 901 first gear slider in this mess, Then told me I have horseshoes up my orifice.
I've been sitting on this shit for 20 years!

Are those syncos from a 901 or a Type 1???

Those were type 1 synchro rings. A little less valuable than the 901 variety, but a nice score anyway. Wish you had been there Doug.

I'm off this weekend, I pulled my tranny this morning and will tear it down tomorrow. Hopefully with only 42K on it I will only need to change the syncros and I will have it back on the road by Sunday....just in time to see it snow outside.

Took it apart. All looked pretty good. Changed 1st and 2nd syncros and flipped over 3rd just to give it a bit more life.(it had a bit of wear on one side.)
Only problems I had were getting the 1st number 1 gear off. It was TIGHT and needed a puller to remove it. Second problem (my fault), I had marked all the shift forks on their shafts but I didn't get the shifting forks aligned properly. Luckily I tested the shifting on the bench and found it to be a little "not smooth".( it was binding a bit moving from side to side) I took it apart and moved (rotated) one shift lever about 1/8", reassembled and all works much better.
Tranny is in the car but nothing else is hooked up yet. Hopefully tomorrow after work I can hook it all up and test drive it.

Oh yeah! got my P284 tool for removing/installing the dog tooth rings back from my customer today. It has only been a few years. However it allows me to get back to work on my boxes.

Yup T1 syncros.....my stash had nothing 914.... oh...except for an NOS 1st gear slider. (IMG:style_emoticons/default/biggrin.gif)

Those tools I showed you Doc (IMG:style_emoticons/default/drunk.gif) were T1 tranny tools, I've identified most of them including a diff measuring tool.
hmmmmm I wonder if a 901 diff will fit it.

Was that diff tool VW385? If so it probably will. But there are several diff's. The early 901 diff is smaller than the later 911/914/915 diff. See this thread on a diff tool. Search Pelican for P258 & VW385, there is lots of info.

The blinking face was for the adjustment. Do you have the jig? Without the jig your adjustments have a very high likely hood of failure. As for removing 1st gear with a puller, are you talking about the large gear (driven) or the small gear (drive)? You had no need to remove the drive gear and if the driven was so tight as to need a puller, that is a concern.

Thanks for the reply Mike.
I do not have the jig but I did put a scribe mark on each shaft before I removed each shift fork. The fork went back on in the same position (linear) as they came off. As noted before, I just had one of them slightly rotated and this caused some binding in the shifting.
Both Haynes and factory manuals said to remove the drive gear (small) from the the shaft before removing the gear assemblies from the intermediate plate. This is why I did it. The gear was tight to remove but it didn't "pick up" and came off smoothly, just tight. When I put it back on, I could easily return it to it's original position with the nut and a 3/8" ratchet. (To remove it again I would still need a puller as I don't think I could pry it off without one)
I guess I could have removed the pinion shaft without removing the #1 (small) first gear but I wasn't keen on tapping the shaft out with the gears still slightly engaged. Now that I see how the bearing on the pinion shaft comes apart I guess I didn't need to remove the drive shaft. This is only the second time I have done this so live and learn.
If you feel that returning the shift forks to their original postion might not be "good enough" let me know and I will take it out of the car and align them properly.

Doug,
other than aligning the marks, did you check the index of the selector section of the rods? You may be ok. As for removing the small gear, completely unnecessary, but since you didnt break the bearing doing it, its not a big deal (IMG:style_emoticons/default/smile.gif) Run it and see what happens.

That's the most important part of rebuilding your Turbo Encabulator.

The part of the rods that interfaces with the shift comb of the selector console. Clear as mud? (IMG:style_emoticons/default/confused24.gif)

Nope, the tool I have won`t work, but if I needed it I could copy it for a 901. Measures the total diff bearing to bearing.

I think I have the diff figured out.... (IMG:style_emoticons/default/idea.gif)
In fact I`m thinking of flipping my diff (new bearings) in one trans and sticking that box into my `67 bug project.
(IMG:style_emoticons/default/blink.gif)

Probably just build another box (IMG:style_emoticons/default/smile.gif)

Why not use a 911 box then? A lot less case work and the selector is in the correct place.
