John,
fun stuff, eh? Just a note on the cleaning of the head stud holes in the case... don't use a cutting tap. In fact, don't bother with a tap at all... just make your own out of an old stud by grooving the threaded part with a cut off wheel on a dremel. Can't wait to see the finished machine :) Best regards, Michael |

I love threads like this. It reminds me of what I can do, what I want to do, and what I wish I could do. Nice work John!

Well, I installed the three missing studs. What a PITA.
First of all, the DIN studs I came up with were Yellow Zinc plated. OK, I have chemicals that can blacken zinc, into the bath they went. Not the slightest blackening. Next, the ends of my studs were not rounded like the old ones, they were square. Oh well, in they go, I would rather lose a concours point than have oil leaks. But what a pain to get them in with the Snap-on Stud Remover, the ends were pretty weak and deformed, and also destroyed the M8 collet for my stud remover, not an inexpensive item! That won't be hard to fix, because it was easy to deform! Anyway I ended up using the double nut method, this isn't a terrible idea, but I used full height nuts, so the stud ended up being proud of the surface. I think I am going to rip these out and use black DIN studs, I just found some on McMaster, which are close enough. I will get some jam nuts (half-height) and lock those on the threads, this should work better than the stud remover which really doesn't fit anyway. Well, on the bright side I finished the case sealing with these studs, and moved on to piston installation. Update on that soon. |
Here are a couple of stud installing toosl that we use with regularity.
The 8 mm installer is made with 1 911 exhaust nut, one ball bearing and one 8 mm cam tower nut. The ball bearing is pressed into the exhaust nut and the 2 nuts are them welded together. For the 10 mm stud installer we use a 911 head nut , a 10 mm hex nut and a short 10 allen bolt. You thread the nut onto the allen bolt then into the allen end of the head nut. Then just weld the pieces together. Use a good quality anti seize in the installer and go to town. It take a little effort to make these tools but once you have them in your tool box you'll be amazed at how often you use them. http://forums.pelicanparts.com/uploa...1216072882.jpg http://forums.pelicanparts.com/uploa...1216072895.jpg http://forums.pelicanparts.com/uploa...1216072911.jpg http://forums.pelicanparts.com/uploa...1216072924.jpg http://forums.pelicanparts.com/uploa...1216072942.jpg http://forums.pelicanparts.com/uploa...1216072955.jpg |
Wow John, you are making Henry giving away his secrets of the trade ;) BTW, nice work on the 2.0 and thanks for sharing.

Henry, that is almost too cool for words. Thanks for posting! Turns out I have a whole bunch of those nuts around and will take a stab at it. I like the fact that it's got a small OD so it will fit down in the fins.

Henry, can I sell that? ;)

OK, I obtained a japanese-made stud remover that works on the same principle Henry outlined- rather than a clamp on the threads, this puts tension on the end with an internal screw. It worked fine, so well that I ripped out the zinc-plated studs and replaced them with black oxide.
The ends are different from the original DIN studs, if I lose a point for that I'm going to convert the car into a 911R. Well, I learned a lot about studs in the process, time to move on to the pistons and cylinders. . . I'll start a new thread for that. http://forums.pelicanparts.com/uploa...1216648458.jpg http://forums.pelicanparts.com/uploa...1216648474.jpg http://forums.pelicanparts.com/uploa...1216648486.jpg |
I love that oil catcher on the motor stand! Alot better than my cardboard I have used in the past. Did you get that at HF?
|
Chad, that is a Summit racing pan. The stand came with a steel one made by HF-- unfortunately they just put a piece of steel in a brake, folded the edges and didn't seal them, so when oil started leaking out it ran out the corners! The Summit piece is much better.
