Thinking I might even be able to restore my old mounts that are missing the rubber where I place the cleaned metal on the mold and cover to adhere thoroughly. Any thoughts?

How much vibration you feel on steering By installing the Mount?

Keep in mind that these polyurethane caulks/sealants/adhesives are ONE PART MOISTURE CURING polyurethanes. If you cast them too deep they won't cure properly. On non porous surfaces you should add a very fine mist of water. Some products can also foam or have voids, so beware. TWO PART polyurethanes will cure no matter what the thickness is.

@JeffLReeb

Жыл бұрын

Could you give more insight on the depth that is acceptable for casting? I have rear diff mounts that cannot be removed easily so the one part poly is a good application for me. Do you water mist the poly after applying it? I would think the water would evaporate rather quickly. Does applying heat (180F) enable better curing?

That throw back tho when he use to do all these type of diy love it!

I just repaired the transmission mount on my 2003 caravan. Filled the areas with locktite pl2 construction adhesive the two days ago . After filling it set over night help placed to under the hood and drive 40 minutes. Actually the one that I got free from the junkyard was the one I filled it was in reasonable condition. I took it for a short ride just now and it worked great so far…

This video was perfect timing. I recently purchased all new mounts and was slacking on the install. I think I'll go with the locktite, as my wife drives it more than I do, and would rather a little more comfort. The stock mounts have over 170K miles on them, so I know anything will be an improvement.

I`ve done this with soft(shore A stiffness =37) poliutherane called SIKA 11 FC. Only difference is that i did not fill mount completely, I left little bit od empty spaces on the end of mount in order to achieve low vibration and allow bit of engine movement. Everything is perfect, engine movement exists but is it is much smaller and no vibration at all. Try this way and you will be very satisfied!!!!

How much u let it sit to cure

The way you brought the vid so good broo

I did this recently but ended up going with 80a liquid casting/molding urethane from McMaster Carr, ~$35 with shipping I believe. Filled a total of four mounts. They also sell it in higher and lower durometer for different applications. Much less viscous than the windo-weld, it fills every nook and cranny and cures perfectly flat. It's between the consistency of maple syrup and honey for about an hour at room temp until it sets. Takes either 24 hours at 180F or a week at 70F to fully dry/cure which is the major disadvantage. I stuck mine on a baking sheet perched on top of some furnace piping (maybe 100-110F) and they felt fully cured within 48 hours.

My daily ride has been sitting for two months due to lack of production due to COVID. Now, I will attempt this. I would rather have a little more vibration than not being able to use it at all.

I did this to one of my diesel MBs because those motor mounts are notorious for collapsing shortly after install. It was awful. 😭 I used a shore 30 Loctite poly because I wanted it to be soft to prevent transmitting a lot of vibration, but to be just firm enough to help the mount maintain its shape. It vibrated like an absolute nightmare. Cold starts would shake the entire car visibly from outside and when hot the AC compressor being spun vibrated it just as much. It drove ok once you were in gear and moving with higher engine rpm, but idling was pure misery. I took them out and bought another set of mounts and put them in which eliminated that vibration. That was only shore 30! I almost went with a 50 or 60 and that would have probably rattled the rearview mirror off the windshield. For a daily driver, I will not personally use or make poly motor mounts again in the future. A track car I would, but not a daily.

They're much better than the sloppy stock parts. I wonder how much of a difference there is between i4s, to V6s, to i6s, etc, and the vibrations.

Of course it will really vibrate a lot considering your using the polyurethane into a diesel engine. Usually a diesel engine has a longer stroke than bore making it provide more torque. More stroke means more torque and more torque means more vibrations. And its more noticeable in diesel engine with lets say 4 cylinders than with more cylinders.

IDIs are different beasts than DIs; much smoother and much faster revving. Mercedes designed the 2.3L 4 cylinder gas engine with hydraulic motor mounts. They designed the 2.2L diesel with solid rubber mounts. If what you say is 100% correct, Mercedes made a grave error with one of the (seemingly) most basic design elements.

Its a great diy trick. Id probably use masking tape and try and get things smoothed and looking as factory as possible but thats just my ocd.kicking in....remove the tape for a clean finish. The degreasing idea is wise not something ive thought of before.....maybe also finish with brake cleaner.

Thinking I might even be able to restore my old mounts that are missing the rubber where I place the cleaned metal on the mold and cover to adhere thoroughly.

My initial thought was that the 3M Window-Weld would be TOO hard myself…but yeah, good/new rubber is pretty stiff! I’ve been doing this for awhile now myself…and believe it or not, you get a little better reaction time and average 1/10th faster in the 60’ if you like to play on the drag strip a little bit👌🏼
