Another Motor Mount Option

I installed new motor mounts from jagsthatrun.com over the summer. Someone had posted about these a while ago, but I couldn't find anyone that had tried them. Here is the website link:

http://www.jagsthatrun.com/Pages/Parts_S10-43-2wdRepacementMounts.html

They use the stock mounts from the S-10 2.8L V-6. These are rubber mounts, but they are completely surrounded by a metal shell, so they can't pull apart like the stock 4.3 mounts. Here are the photos from their website:

Unfortunately, the 2.8L motor mount won't bolt directly to the 4.3 V-6. Instead, the motor mount bolts to the frame, and an adapter bracket bolts to the engine. This means you have to replace both the mount and stock frame pad, like you were installing solid mounts. The adapter bracket they provide looks very solid though, and everything bolted up with no problem. (Except that changing mounts is very bit the nightmare people say it is.) Everything seemed to line up fine, with no interference around the fan shroud. Here is a photo of the passenger side mount & adapter bracket installed.

I only got a chance to drive the truck a couple of times after installing these, because this turned into the summer of replacing things that broke. They definitely were better than the broken stock mounts. I like having the rubber mounts for ride quality, and hopefully the steel shell will keep them together. If I have to change them again in another 18 years, the physical and emotional scars from the last time should have faded.

I ran them for years on my V8 S10. When I pulled the engine I noticed that the rubber did stretch a bit and sag down but they were still in one piece and doing their job. Someday I'd like to fab up a set of these:

Some guy on a S10 forum used to sell those. If I could only figure out where to buy those bushings the hard part would be done...

Baja Customs makes a replacement 2wd mount like the one you pictured

I'm not sure if they're doing a 4wd version but they're definitely pretty stout.

This is how i roll on all my motor mounts. if you can weld good and have a grinder, you can do this. Pretty easy and almost never fail, unless they get to hot.

Would delrin bushings be any better when dealing with the heat?

Me and Berzerker helped a friend out with those type mounts on his Cherokee, Baja Customs rings a bell. It wasn't a bad job and they definitely looked like a nice piece.

This is what I use. You can get them from Chassisworks. These fit on the block. You have to make the bracket for the frame mount.

What kind of bracket? Like a solid mount?

We do cast polyurethane parts where I work. Get me a dimension and hardness, and I could make you a set. Or you could probably get them from the manufacturer that John just posted.

Good question. I don't know the melting properties of Delrin (AKA Delron) But it has to be higher than poly. However, now you are at the practically solid mount stage, that shit doesn't give much. I would just go solid at that point.

Nope, it is more rigid than nylon but it's low melting temperature (around 350 degrees) and impact strength would rule it out. It does machine very nice though...

We have to machine bucks out it for our customer so that they can check part thickness with a magna mic. I've lost count of how many that we have made since they have to have one for every part.

Re: Another Motor Mount Option

i'm thinking i'll make a complete motor mount setup that uses the energy suspension poly bushings. They'd look like some of the things above, and the bushings would be replaceable if they ever did melt/break down. let the research commence...

OK, this is what I'm thinking...

If you are thinking the same thing, I'll help out by:

1) Cadding up and cutting the frame side mounts.
2) Building a jig to weld these mounts in.
3) Welding the 1st set together.

I've searched in the past but I wasn't able to find the bushings and the appropriate size tube that the bushings go in.. If you can find that stuff this will get easy..

I found my notes from when I first discovered these mounts. The guy that was selling them went by "BoostedThrills" on the S-SeriesForum. He was asking $125 for a set. It looks like he still has his photo album online:

Re: Another Motor Mount Option

i might be able to help provide the poly mounts... buddy is a rock crawler and makes mounts like these all the time.. might even be able to get a discount
