poleurathane motor mount problem*
« on: July 17, 2010, 09:51:13 pm »
Anyone ever use these energy suspension motor mounts? They are suppose to fit ur stock clam shell mounts. I put them in my original mounts and now they wont line up! I can get the long bolt thru either side no matter what I do. I don't want to take everything back apart unless I have to! Any ideas? Should I just go with a stock mount and see if they line up? By the way truck was a 305 and I am putting a 355 back in it, but that shouldn't matter right....

Use stock mounts, you'll have no problems with them.

no it's the same, I think they have tall and short mounts not sure though. Maybe you got a tall insert and need a short? I don't know, but when you say king bolt you mean for the mount itself or the one that goes thru the engine side mount thru that insert? I had a heck of a time putting a motor in my 85 mcss before I sold it, had to pry the insert up front and back and drive the long bolt thru there, it sucked.

I used those exact motor mounts and found it to be much easier to leave everything loose until every bolt in in then start tightening them down, but yes for some reason they don't line up exactly.  One driver's side tabs on mine sits against the engine part of the motor mount, but I have no adverse effects from it so far.

Yes the long bolt that goes through both! What did you pry on the rubber(poly) or the metal? There a pain in my u know!!! I thought about leaving everything loose but the instructions to the mounts said to go ahead and tighten em up(liers)lol!

Yea I had to try and get a bar in behind the rubber and pull it up. The block side mounts seemed to keep pushing the rubber down I got a bar under the rubber insert and pryed it up enough to start the bolt and tap it thru with a hammer, once the threads came out the back to put a nut on I was home free. I don't think you'd need to pull it all out just raise that side or one side of the motor at a time and work on it. Or if you think you can do it maybe bolt it allto the block, sit it in place then bolt the clamshell/frame mount part to the frame.

What about a center punch?

No doubt I shoulda called him when I was working on the mcss. But yea mine were stock in the mcss and it sucked I had to use a prybar under the ruber parts and lift it up. Meaning my bar towards the crossmember or center of the car and pry the mount towards the upper frame or the ds fender to raise it up inside it's clamshell, like it had slide down.

lol not good. I think I might try as mentioned then loosen up or maybe undo them from the frame, bolt em to the block, and then try and get it in place and bolted to the frame.

I know this is a dumb question but have you tried flipping sides? Maybe the inserts are side specific or something?
