I'm refurbishing the luggage straps. Cannot say if they are original or not. They look it. Clean the leather, eat the stale pecan waffle.



One of these might be a replacement, they don't match exactly




Which one is original?

Changed motor mounts and refurbished hardware. cleaned up a little. This will get me through the summer then pull the motor for winter and move into the engine bay with a cleaning kit.



These will be replaced


I got the sludge that was caked in the corners and crevices around the mounts


Before me, I'm confident no cleaning agent has touched these surfaces in this decade.

Dirty filthy engine

It looks like the motor has not had a rag on it for a decade or so, probably never underneath. That's about to change. I accidentally found it's a lot easier to work in the engine bay when it's 4 ft in the air, just put the air cleaner at eye level.

Am I wrong to think that if I clean everything, I'll be able to determine where all this oil is coming from, or if it's old leaking. The cross-member is caked with old oil residue.







heat exchanger before...



...and after about an hour with engine degreaser and rags. Too close quarters for wire brushing. Is it supposed to be bare metal or under-coated?



What about those rusted pipes? Should they be replaced sooner or later?

Trans mounts

I want to change the trans mounts, but I have to clean the area first, grease cutting solution 3:1 Simple Green/Dawn, non-flammable, biodegradable.





FAIL
on the transmission mount replacement. If I am not mistaken, this is what the books are referring to about the early models, the support bar and mounts are one piece and the rubber cannot be replaced, the entire piece has to be replaced, but the piece is no longer manufactured.



At least it's clean.

That mount is similar to the 930/911 Turbo gearbox support (the bosses for the bushings are welded in) and Rebel Racing makes a two piece (two halves) replacement bushings for that type support that are very nice. I bought them recently and they are excellent.

The ones listed for a 911 are on the linked page (first item) . . . you'll need to look around to see if there is something specific for your year, or call Clint (the owner) and ask him if the 911 and/or 930 bushings will work in your car.

PS - you remove the old bushings by burning them out with a propane torch - very easy that way . . . support bar off the car and gearbox supported by a stand, obviously.

Done, done, and to be done, thanks. Clint is on top of things. I called, didn't live a message, was in the middle of emailing the question and he called me back. Blacks ordered, next up, pull the support bar.

Excellent!

Here's another un-asked-for tip (just the! ) - when you go to re-install the support, do not tighten the four nuts that attach the support to the studs on the gearbox, until you have gotten the chassis bolts started - it is very difficult to get the chassis bolts lined up properly, and the cross threading risk is high, if the gearbox nuts are tightened down first.

Hi Ken,

I have been planning on doing my tranny mounts and actually have the parts from Pelican laying around on my workbench. It seems like an easy job with just pressing in the new mounts into the old cross member. I will let you know when I do it if you are interested.

Just a FYI, the Rebel Racing bushings (which I assume you aren't talking about) are in to halves (top and bottom halves), so there is no pressing in of those.

I have seen this car and the previous owner several time on PCA meets, when I was a PCA supporter back in the day. Glad to see you are working on it.

Motor mounts

...changed them to these for no apparent reason other than they look cool. I will keep all stock parts for future owner who might be nutty about bone stock, but chances are that new owner is my son and he can just wait 30 years or so for it.






I can change these out in about 10 minutes now and even figured out to let the motor down a little to be able to get my hand under there for the two nuts holding the mount, and then raise it back up to align everything, the through bolt slides right in.

Transmission mounts

I pulled the transmission support brace



made a cradle for the jack


cleaned it up, new bushings ordered from Rebel, after I forgot I ordered a set from Pelican.

The question is: What's the difference between polyurethane and polygraphite insofar as the performance is concerned. I realize they are two completely different compounds.



You can see how the rubber is all dried out and cracked, this was probably the squeak I have been hearing back there.

Heat exchangers

I stripped them a little. I did not polish them yet, but I will. It''s not easy working upside down with a heavy drill.

Now what? Paint with clear 500 degree engine paint? Black paint? Undercoat material? Beats me. I'm inclined to clear engine paint.



Before





After

Hi Kristoph, Sorry about delayed response. I'm practically done. I just got the brace out today and cleaned it up. The old bushings can be drilled out and discarded. The new ones are split like a bagel and require no pressing, they slide right in.

I bought two sets of bushings by accident, want one? I'm try to figure out the difference of characteristics of polyurethane (Rebel) vs polygraphite (Pelican) to decide which set to use. For everyday use, I doubt there is significant differences.





these are the Pelican poly-grqphite

Thanks, but not quite there, give me a couple hundred more hours. I won't be happy until I pull it and put it on a rotisserie. Next winter.

The transmission support brace bushings are changed to poly graphite. Thanks to RawKnees tip; the key to putting it back together was installing the longer rear two transmission stud nuts loosely, leave the front two off, then start the bushing through bolts. Once the through bolts are started tighten all four transmission studs, finish with the bushing bolts. I read 17 lbs on the stud nuts, 40 lbs on the through bolts




I like shiny bits and pieces

The fan housing

Can this piece be taken off while the engine is in the car? The alternator is inside there, right? Any tricky wires that will break? It would be nice to get this crud off it, maybe powder coat it. What do y'all do?

It will come out but it is very fiddly. It is magnesium so use care so you don't break vanes or blades. If the alternator does not need replacing avoid trying to pull the shaft. That is where all the damage occurs. Please don't powercoat the fan. It never looks original. Lots of articles on how to do it correctly. There is a guy on Rennlist who does beautiful fan restoration. I'll see if I can find a link.

Here is the best thread. There are several others. Pay attention to the Gibbs treatment. Would look great on an original E.
