Considering the master I removed from this car was installed upside down, I think the previous mechanic did just that! Imagine trying to bleed one of these clutches with a reversed master....

Hindsight I'm glad this one was leaking otherwise I would have been dying with trying to get the clutch bubbles out.

I don't see why not. Might have to fiddle with the hose orientation a bit more since I think that placement is more crucial with the 10" unit. It's been a while since I did the clutch master in my 81.

That's what I plan to do, I took the line off before removing the master from the firewall. I think it could be done either way, just leave the fitting lose if attached first so it can rotate.

My avatar is always willing to help, she wasn't home yet and I was anxious to try this method solo. Even with a partner I'd still use the string to pull everything in easier.

I've seen it referenced for both jobs, but I think more commonly associated with the hose. For me, if any 928 needs a new hose I'm going to do the master (with a rebuilt unit from White Post Restoration) at the same time. Then neither shouldn't need to be addressed again for a very, very long time.

Sorry Doc, there is no "right way" when talking about cutting a hole in the car to perform a regular maintenance job that can easily be performed without.

Justifying the correct way to cut the hole is like saying there is a preferred way to catch herpes.

If I find myself inspecting a 5-speed 928 with signs of a fender hole, I'm going to assume the rest of the car has been maintained along the same lines, like this car:

I remember when Greg called me because of this thread:

He still didn't believe this was a thing people did...... he wanted me to let him in on the "joke".

Now you've done it!

What about getting some all-thread rod and putting it in the two threaded holes. It will stay in place as the edges of the thread should catch the firewall. Go inside put a nut on one to pull it in place. Remove the second one to install the bolt, then remove the first one to install the bolt.

Been a while since I was in that area of any of my cars. The 83 race car will need this for sure.

The string method is cheaper. Everyone has some of that at home

There is no weight savings. The 10 or so inch of metal removed by the cut off tool might be measured in grams.

You're right of course. There's certainly no reason for cutting a panel for an easy job. Now, let's get back to discussing the clutch blue hose job.

Just cut the head off of a bolt. We all have those lying around, so no cost there.

Brilliant method, thank you for posting it.

I did it the Rob Edwards way

I think I also used the headless bolt method. worked for me and no cutting either. it can be done if you are patient, have a beer or two and a lift. life is better in the slow lane.

So you're saying there are some weight savings! Of course, the problem is that all that weight is coming off one side of the car, which might be okay if you're only going around in circles, but would be dangerous for any other application. To be safe, cut a hole in the right-side fender to balance things. This will double the weight savings!

Note: I'm joking (as I was in my original post). The performance benefits from cutting a hole in the fender is rivaled only by one of those electric turbochargers for sale on the internet. But, as long as you're coming up with justifications for cutting a hole in the fender, you might as well throw in performance advantages, too.

The justification was saving 5-6 hours of time to replace the blue hose without any loss of strength, or affect to the cosmetics of the car. The flap cut took 6 minutes, and the blue hose install took 4 minutes, then returning the flap and securing it with a sealant took another 5 minutes. Of course, some folks would R&R the engine before using the hole/flap method. Meh - that's why I live in the US.

Great writeup!

For reference, (I didn't do it, but man did it make it easy to access the master), this is what it looks like if you cut a hole in the fender.
