RED LINE/Zimmerman------ Consumer Report

------------Back to Redline with stuck motormount bolts----------
The SC, unlike the 911S, has the rear motor mount spar bolts threaded into the spar. Rather than take a nut off and pull the bolt out, the bolt is screwed into the spar. If some dingdong over twists the torque or if rust is a factor, removing the bolts is difficult. I broke both sides of the part car when we took out the engine. Attempting to change the mounts in our SC driver, soaking in rust buster and my impact at 120psi had no impact on the bolts and the cheater bar only flexed the spar. I took it over to Marc and presto it was done. I did not think he could get both out without breaking at least one side, but he did.
When I went in he was working on a Weber carb 911 with the worn shaft/airleak problem. He told me he has access to a better Weber redesign carb with a sight glass and roller bearings. Parts are at hand for this carb, unlike some of the older webers. This looks like an ideal upgrade for our SC.

Seems like a large enough impact and/or heat woulda done this at home. What did they use that nobody else could?
That is not a knock on them. I've yet to see a set of mm bolts I or one of my buddys, couldn't extract.

a litle heat goes a long way ....
The first time i did mine my impact couldn't get it either, But my 1/2 inch drive set and a big *** breaker bar got her out. I just made sure i paded the area well in case I slipped.

We dropped off the 911, drove the 3 miles south to the Queen Mary and had lunch top side. We also went to the wedding chapel where we were married some 40+ years ago. Anyway the total of lunch, gas, Porsche repair and $5 for parking was close to $75.
The point should have been---- IF you have a problem with the SC spar, this is the guy to fix it. IF you are in SoCal.--------------------------- the crashed RS is done and it is lovely.

Dave: For the SC you want 80W/90 Kendall Three Star GL-5 dino gear oil. And for the LSD you need to contact the manufacturer - if the LSD unit was factory you'd want Kendall LSD additive.
I know nothing about Royal Purple, have never used or sold it - sorry!
No apology needed - welcome to the SC world!

Pete, is this Kendall product (here) the gear oil you were recommending for a 915 with a factory LSD? It appears that the LSD additive is already blended in. Am I reading that correctly?

FYI: The additive stinks something awful, make sure you wear latex to put it in the trans, if you get a little under your fingernails you'll be smelling it for days!

Thanks Pete! Glad all is well in the land of fruits and nuts. I'm going on a search for the Kendall product today. Thanks again!
Toby
BTW for those of you in the Dallas-Fort Worth area, you can acquire the Kendall products from Double-C Distributing Company in Carrollton. 972-3232-0120. They also have the additive in the 4 oz container. TBP

I assume that you (Pete) would also recommend this brew for a 930 4-speed transmission with a factory LSD?
