⚠️ Note: Wear gloves just in case you come in contact with uncured polyurethane. Do not use your food oven when baking the polyurethane. Also, all oven temperatures mentioned in the video are in the Fahrenheit scale.
I couldn't find anyone that produced replacement bushings for my NYPPD (Torque Solution clone) motor mount. The only ones I could find were very hard 95A bushings that I had to retrofit. I decided to cast my own 80A bushings using high performance liquid urethane in a 3D printed PETG mold I designed. I cured them in a dedicated craft oven for 18 hours at 150°F, and the results turned out great.
If you do decide to cast your own bushings, you do so at your own risk. Please make sure you are comfortable with this process and that you know what you are doing. Read and follow all the safety information and instructions provided with the liquid urethane and do not use your food oven with the liquid urethane.

As I am watching this I am 3D printing a custom gearbox mount for my Volt. I am using TPU 95A with 40% hexagon infill and 5 shells plus 5 bottom and top layers. I just did a web search and it seems that TPU 95A may have not been available at the time of this video. It is amazing how 3D printing has revolutionized the DIY engineering scene. Great video!

You can use PVA (which is a water soluble support filament) to print the molds. After casting you can dissolve the mold away from the casting with water.

You normally dont need to destroy the moulds, just squirt some compressed air down the sides and the rubber part will pop out. If it is hard to get down the side drill a tiny pinhole in the bottom and squirt the air in the pinhole, then the pinhole can be covered witn sticky tape for the next mould use.

@VampyreX13 3 ай бұрын

The mold would definitely need to be printed thicker for that.

@drrock5356 Жыл бұрын

Another good variable to check is how much the engine moves when you load the drivetrain. Pop the hood, start the car and put it in drive (in an automatic), but hold the brake with one foot, and give it some throttle (so the car doesn't move!). Note how much the engine rotates as it revs.

@kush_tography7960 2 жыл бұрын

I know this is an older video but the poly set up like that because of the 170 degree temp. I'm surprised the can even suggest to get it that hot. The hotter you heat it up, the faster it sets up. I would went with about 150. Also, if you have an air compressor, those will pop right out the mold with a little air blast.

It's my first time working with the stuff, so I was just following the instructions as close as possible. You're the second person to recommend using an air compressor, which I do have. If I have to make more in the future, I'll remember that.

I just need to edit it together and then actually swap in the mount to test it, but I've been busy this week. I promise I'll have it up soon. As for selling them, the only issues are that I would need to test it to make sure there are no issues and I would need a mount to fill. Also, you need to use the entire contents of the can of urethane to have the proper mixing ratio, so that would be a huge waste for one mount only.

Unfortunately, I just don't have the time. At most, I might be able to design and 3D print the molds for you, but I would need precise measurements. My recommendation is to call Energy Suspension (949-361-3935) and tell them what you need so they can find you a compatible, if not exact, part number to order.

Motor mounts are really large, but I'm hoping to do this with differential bushings for my SRT8, then move on to suspension parts as well. Freaking k member bushings are $200, diff are $150 etc, just ridiculous by the time you replace all the the link bushings and such. Car is multilink front and rear, probably 30 bushings, averaging $25/bushing or more. Yuck. can replace the entire arm with rubber bushings for that. Here's an idea I'm curious if you're interested in trying- what about casting an insert for the oem motor mount, other subframe mounts etc, IE how torque solutions does it. That what you don't get much extra NVH until it starts to deflect significantly.

@VampyreX13 2 жыл бұрын

I thought about making inserts, but I think it's just better to fill the stock mounts once you trim out some of the extra rubber per kzfaq.info/get/bejne/et5xf5WfnLzYfYk.html. I don't have any issues with NVH with my mounts.
