I'm missing something here. I've never had to use heat. The home made pullers are simple and very effective, but I don't think I have ever had to do that either. A little tapping with a plastic hammer against something suitable, like a socket on an extension.

You don't freeze the pin and heat the piston to insert the pin, so why would heat be needed for removal?

Dempsey doesn't mention heat in his book - he describes using a screw driver for the tapping. Anderson notes: "The original pistons had a light press fit for the pin, so pistons had to be heated slightly for installation. The modern versions of these pistons has a slight clearance so the pins may be pressed in with a finger."

I don't know about Bentley, but on some details Clymer had some klinkers. Their description on how to remove the pressure plate included screwing in some bolts to relieve pressure, but did not note that this was for the 911 transmission only (or maybe the 901), and had no place in dealing with the 915 PP, confusing a whole generation of us DIYers.

Porsche's workshop manual for our cars, at least through the end of the SCs, is two books for the earliest models, and four or more books of updates. Perhaps the manual for the 2.0 model mentions this slight heating, but the updates neglect to mention you don't need to do it from some model on?

So I would suggest you put the propane torch away.
