Default Re: Engine Mount (Polyurethane Fill)

Okay, Part 2,

Only took about an hour and a half to get the new ones installed, engine dropped a bit, bolts finger tightened, engine dropped the rest of the way and bolts torqued as much as I could by hand (upper ones are a PITA).

The car runs much better now, no movement at all. If the mounts have no fluid, then they are MUCH thicker rubber and give so little I can not tell.

I will leave them in while I work on the originals.

I have cut open the original broken mount after draining completely and degreasing as much as possible. There is a reservoir in the bottom of the mount with a star shaped split valve in it. I cut out the valve at the steel and then cut out the outer part of the mount to make room for the Polyurethane.


Next I will be making a jig to hold the two pieces of the mount in their original position (based on the unbroken mount) and then I can drain the second mount and cut it apart like the first.

The original mounts are quite a bit leaner when it comes to the thickness of the rubber casing that mates to the support steel and holds the fluid compared to the ones that were sent.
