it's true that the tool does not work for 2nd gear. on 1st, the gear is larger than the toothed hub, so there is something to push against. on 2nd, they are the same size. i use a knife edged chisel and hammer to work the ring off. once you get it away from the gear a bit, you can pry it off the rest of the way with a larger tool. wear eye protection and clamp the gear crossways in a vise with soft jaws.

Sort of off the 930 topic, but raised in a response:
The paper tranny gaskets cost even less if you don't bother to use them. Loctite 574 (orange case sealer, anyway) works fine. I first learned this when I had to pull the shift fork guide cover plate, the gasket tore, I had no gasket, and needed to get things fixed and back so my wife could race the car the next day. That was the advice I got from a shop owner buddy I called in a panic. I liked this so much I did it with the larger mating faces as well on later transmission adventures. No more leaks than I had experienced with those flimsey paper gaskets, and no apparent significant dimensional changes either. Walt Fricke (915, not 930, experience) |

So can someone give a list of the special tools that you need to do a 930 tranny right?
I'm sure JWW can chime in on this. But since I do my engines now, I may as well learn how to do my tranny too. My tranny is currently in the shop for a rebuild, and while I'm sure it will be a while before I will need those services again, I'd like to be prepared to tackle it myself next time. Brian

Tools for 930 rebuild
Brian,
Here's a list of the 930 transmission tools off the top of my head. synchro hub removal tools These are thes only "special" tools. Pelican sells them. 1st gear tool PEL-TOL-P224 3rd/4th gear tool PEL-TOL-P223 You can get by without these rather expensive tools, they just make things much easier/quicker. Note: These tools are weaker than there 915 equivalent. I found it necessary to heat the dog teeth in order to pull them off without damaging the tool. gear puller You will need a puller with long arms. The one I use is made by Kukko, I have a 2nd set of longer arms (not pictured) that I use. ![]() hydraulic press to R&R the synchro hubs (aka dog teeth) hope that helps -Chris

I know this is an old thread - but I'm pulling my 930 box apart at moment.
I did a 915 box a year or two ago, and recall locking the shafts in two different gears to hold the shafts from turning while taking the end nuts off. Can't remember how I did it, but will it work for the 930 box - can't remember which gears I used - and there is an extra one in the 915. Alan |
