Post subject:  Polyurethane Motor Mount install

So I finally decided to get around to installing one of the poly motor mounts I bought from summit. The part number is 13-501 and this is the for the timing belt side, which is a hyundai elantra mount, the front mount already has a poly motor mount, its a stock 1.5 mount, the rear is about 1/2 smaller than the timing belt, which the rear is also a stock 1.5 mount as well, and I havent removed the tranny side yet.

Pics!

stock elantra timing belt mount, really really soft rubber!

rubber removed with a drill

Image

theres a metal ring on the inside, we used a sawzall and cut a slit in it, then bent it with a hammer and large screwdriver, then it popped right out! or you could cut 2 slits in it and try that as well

Image

its out!

Image

and the 13-501 mount is in, with some grease!

Image

next up, stock 1.5 rear mount! Just gotta find one thats prothane :wink:

The part #'s for the prothane mounts are in the archives. I believe 13-506 is correct for that mount.

I believe the one that was made for the front motor mount of an Eclipse works perfectly in the rear. Don't quote me though. I heard it from MattGSR :)

13-503 was the box that the one I bought from him says, although I don't know if the box is the same as the mount he sold me.

this is the part number that you need for the rear motor mount granted that the turbo and nonturbo rear mounts are the same 13-506
you must take off the inner metal ring also

What are you guys doing for the front motor mount? I have 2 each of 13-506 and 13-501. The 13-506 (which i used for the rear mount) is too small in diameter, but the 13-501 is too thick in cross-section. I think I heard of people using the 13-506 for the front also, but I don't see how this is possible. Heres some pics with rough measurements of both 13-501 and 13-506.

Here's the stock turbo front motor mount. It has a another soft rubber insert that fills in the large gap, but it's taken out for this picture. This this thing is really mushy and I would love to replace it with a poly insert. It measures roughly 81mm in diameter.
Image

The 13-506 measures about 71mm. Maybe others are using a different mount with this insert?
Image

This is the 13-501 measuring close to 81mm also. This should squeeze into the mount but...
Image

It's way too thick. measuring at about 50mm. The stock mount is about 38mm thick.
Image

The front mount next to the smaller rear mount with 13-506 poly insert installed.
Image

Does anybody have an idea? I can cut the 13-501 down, but then I would have to order another one to fit the timing belt side. Do non-turbo cars have smaller front mounts? It would be much easier for me to run to the junk yard and grab one of those if the 13-506 will fit in it. Also, please put this thread int the information archives!

Hows the fit on the 13-506 for the rear mount? Did you have to cut out the inner metal ring? Why couldnt you shave off 6mm from each of the innner part of the urethane (the 2 pieces that butt against each other when inside the actual metal mount)

So, we already know which urethane to use for the timing belt mount, with pics to prove it works. This is the only thing holding me from dropping the motor into my car.

The rear mount fits perfectly. I did have to cut the metal ring out, but once I did it just slid right in and was a snug fit.

I also installed a 13-501 mount on the transmission mount side. This one was a very tight fit. I put the poly insert in the freezer and smashed in in with a vice and some grease.

I could shave some material off the inside of the mount, I was just looking for another solution because then I would have to order an additional 13-501 mount for the timing belt side, and I would have an extra 13-506 mount that i have no use for. I did a little more searching and found out I actually need 3 13-501's. Anybody have a 13-501 they want to trade for a 13-501 lol?

I just found out that the transmission mount is a little too thin to fit in the transmission mount side. There is a gap on both sides at would allow some slop. I will probably space it out by welding large washers to the inside of the transmission bracket.

I initially used the 13-506 for the front motor mount without takng out the inner metal ring, but the fit wasnt as snug as i wanted to. Looking at the measurements you have for the front mount, it looks like the 13-501 will fit good even if is wider by about 11mm because if you look at the mount and the mount bracket, there is space on each side of the mount and the wider 13-501 poly inserts will fill that gap in, and when you bolt it on and tigheten the nuts it will compres the mount further and make it a snug fit. I fixed my issue on the front mount i had by having biglady (here on the borads) make me some aluminum inserts for the front. I would have tried the poly 13-501 if i took measurements for the front.
You should try putting it on and see how it fits, it does look like it will fit ver good from the pics and measurements you posted.

Is there another option for this? Anyone know of a motor mount that would fit perfectly? I will be buying prothane inserts myself and I'll be following along with this thread. Please keep updating. :)
