To skip the intro where I explain everything you need to know about poly mounts go to 4:00 where I start taking out the old ones and pouring new ones in.
Since a lot of people are asking this: The product I used is Reoflex 60 from Smooth-On. https://www.smooth-on.com/product-line/reoflex/
I am not in any way sponsored, endorsed, supported, etc. by this company. This info is also in the video description but no one reads that apparently :) There's a lot more good options in terms of liquid urethane out there probably. If you don't want to burn the old rubber and measure the pin position I suggest just filling the gaps of your existing mounts with 3M window weld. It will yield results very similar to what I achieved in this video and it will be less work. I am also not affiliated, endorsed, supported etc. by 3M.

Alexander Rivera Redondo: Cuáles son los ingredientes ,y cuánto se pone de cada uno ,por favor, y muy bueno y saludos desde mí bello país costa Rica

john coleman: I just used window weld and filled the existing motor mount with that. That looks like too much work for the same result. Nice work though!!!!

Abbas Alabdali: do you recommend to make lower arm bushings?

nick love: Ok what dye is that? Water based? Oil based? When i use water base i get a sponge not a solid polyurethane

MrZeddy100: Mate that was awesome. Well made video and very informative.

Navas Rahman: If using a vacume chamber befor dry, will be more perfect bounding
And use branded good quality PU

K24 Accord: I just filled one of my mounts with it polly urethane 5 bucks vs 65 dollar mount

E Honda: What hardness did you mix?

T-rev Motorsports: Cool video man. Those came out sweet and with a little clean up they could look even better. All the people saying it won't work are overthinkers who probably don't act or build their own stuff for fear of failing. I've filled solid motor mounts on hondas using both window weld as well as the less known pl construction adhesive which dries to about a 95a and is super stiff. With hondas solid mounts are the difference from being able to shift into 2nd at redline or missing the gear from the transaxle shifting out of place and loosing throw from the shifter rods. Well worth doing if your building a high hp car. 🤙

Kimball Scarr: Actually contrary to many comments about the "bonded in" nature of the pin and outer ring to the urethane, I believe here what he has suggested, is the best of both worlds. The STOCK RUBBER ones are around Shore 40A to 50A but the Urethane can similarly be purchase to Shore 40A or 50A or 60A or very soft Shore 10A or very much harder in the higher Shore D scale. The comparison is urethane compared to rubber have slightly different absorption of vibration and slightly less stress defection for similar Shore hardness. This has to do with modulus of elasticity. If you pick a urethane similar to the original rubber bushing the stress defection would be similar with a softer, i.e. more energy absorbing, urethane bushing as the urethane has a higher modulus of elasticity and less stress deflection all things equal. As urethane is basically both higher tensile, and compressive strength for a particular hardness its going to absorb more energy so deflection will be less, and the internal stresses will be higher. So the idea of going harder is bad as it increases shock loading with high resulting internal stresses. This leads to reduced life and compression set unless carefully engineered, just like rubber bushings. But urethane is an engineered chemical whereas rubber is made like making a cake from a combination of materials coming together to form a unified whole, heavily dependent on processing the same. Still don't push it if you don't want to crumble your bushings be careful. You may have better engineered material but you don't want push it too far or it will deteriorate just as bad or worse than rubber. The difference is rubber will gradually give up whereas urethane will all of a sudden give up. He is on the right track not to allow sliding movement and accomplish suspension normal deflections with deflection of the urethane like is done with rubber bushes. Auto suspension engineers have a 100 years of experience and mass use to back them up with the bonded in flexible rubber bushes technology. The urethane applied the same way is a change of material not basic design... so the man here is right to build his bushes as he does.

Wolfenstein Hoffman: Be careful doing this. A polyurethane bushing is suposed to act more like a bearing and be able to slip/rotate slightly. That is why they always come with sleeves and will squeak without grease. The rubber bushing is bonded on to the metal on the inside and outside edges. The rubber bushing can flex. Doing this bonds inflexible polyurethane to the inside and outside edges of the bushing. This will be far too stiff and put too much stress on the polyurethane. Also instead of absorbing impact from the road these bushing will just transfer the energy to your drive train and chasi. A full set of legitimate polyurethane bushings is like $300 and worth every penny.

Dksuzana Wati: bla..bla..

Nigel Charlton-Wright: Hello there, could you tell the diameter and width of the MR2 engine mounting please? It looks as if it would be perfect solution for my Humber's rear leaf spring front bush. Great video.

Fernando Antonio Rios Ceballos: what chemicals do you use to create polyurethane?

jeremiah stokes: How long did they work

Rob Hill: Thanks for this video. I have a 1996 Riviera with a bad motor mount that is impossible to replace. They simply are not available, and even the used ones from salvage yards are all so old that the rubber is gone. But repairing my motor mount using this method sounds like just the thing I need to do. Thanks again.
