Engine/Transmission Mounts
I purchased aftermarket engine/transmission mounts, I forget whose, for my SC. The problem (assuming it is a problem) is that the replacements are just the rubber parts without the metal frame/container/whatever.
So, how do you get the old, hard factory rubber out of the metal part without destroying the latter? I can think of one solution, burning/melting it out with the flame-wrench, but this will no doubt stink up at least the house (which the wife won't care for) and maybe the whole neighborhood. Ideas?

Press or vise
Hi Steam, do your bushings have a metal sleeve in the center??
I just installed engine and tranny mounts. These were a polyurethane material, two pieces with a steel sleeve. I used a press to push out the bushing from the mount, (the rubber deforms enough to allow this). Then placed the top and bottom pieces in place and slid in the sleeve. If the mounts are one piece, I’d check with your supplier or the manufacturer. HTH, Chris |

The new mounts are two-piece. Both top and bottom have steel sleeves that interlock when installed, making the requisite steel center sleeve. No problem with that.
But first you need to get the old factory mount of its stamped metal housing. It has a one-piece steel center sleeve that appears to be molded into the rubber. I am assuming the rubber is hour-glass shaped and was maybe pressed into the metal part of the mount. However I’m afraid that as hard as it has become trying to press it out might destroy the outer pressed sheet metal part of the mount. I had one of those “good idea that didn’t work” moments awhile ago to drill a bunch of holes in the rubber around the center sleeve to relieve some pressure and thus be able to pry it out. No such luck. So I’m thinking a bit of air pollution might be in order. I’m still thinking on that! Further ideas will be appreciated. I am certain I’m not the first to run into this issue!

I’ve seen people drill them out, as well as using sockets in a vice if they don’t have access to a press.

Utility knife and start slicing away?
Heat the metal portion with a heat gun to get the rubber slippery and then punch the rubber out with a press? |

Update - torch idea will not work either. Sets the rubber on fire, but not enough to notice. It would take a very long time to burn one out. I’m going to take to the shop Monday and try a press.

The press will get it done.
If you can’t rig up a press set up in a vise, then take it to the shop, couple of minutes work.
Then, you get to agonize over do I put the washers on concave, or convex :-) chris |

A press is the answer. Popped all four of them out in less that two minutes!
