1995 riviera Front Driver Side Transmission Mount

Hello all. Sorry if my post is a bit out of place, i cant seem to find a topic that gives any answers on this subject.

Has anyone ever re manufactured one of these mounts? i have one from the junkyard but i have no idea how i would build it back up if i were to strip all the rubber off.

Or does anyone know of a suitable replacement that would fit?

The P/N is 22174975

Check RockAuto.com for inserts to replace teh rubber in the mount.

I have heard of people using 3M Window Weld to remake mounts - take a mount and fill the voids with Window Weld - but there are different grades of the stuff and I don't remember which is suitable for motor mounts, nor whether to remove all the rubber and form voids with drinking straws or ice cubes.

Well i did that with the three other mounts but im down to that last mount that doesn't seem to have an insert. It looks like the whole thing has rubber around it and 2 bolts coming out the bottom.

Oh that one.  IIRC it is liquid-filled - see http://www.gmpartsdirect.com/oe-gm/22174975.

I dimly recall someone making up a replacement out of one or more neoprene hockey pucks.

You could use solid neoprene blocks and common hardware to make a replacement.  Tough part will be machining the neoprene so it holds the bolts but does not crack up.  If torque transfer is your goal you could have a machinist make you a solid mount, there are other issues that come with that however.

For those blocks see http://bometals.com/products/joints/expansion-joint-material-formers/neoprene-rubber-solid/ and to buy them check Amazon and eBay to start - however a local/regional supply house like Grainger should be able to get them for you cash-and-carry. Also, if you know or can find out (like, at a transmission shop) the Anchor (a mount maker) number for the mount you likely will find it for short money on eBay, see http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=solid+rubber+motor+mount&_pgn=2&_skc=50&rt=nc.

Also IIRC that mount and its cousin (the round one by the crank balancer) are rarely replaced. The round one does not take much of a beating at all and the one you're looking at is not that easy to check/reach.

Good info! thanks man i will see if there is anything i can come up with and share. I will try and see what i can do to my spare one from the junkyard.

They seem to be available new - less than $150 on GMPD which is not free but might avoid other issues. Take the part number 22174975 and ask perhaps a dealer, or put it into a web site like Amazon or eBay and see what gets coughed up... Might be more, though.

There's a lot of information compiled here. Most is for Series II engines, but the same principles should apply. Best of luck.
