Powerflex lower engine mount install
Good Evening,
I installed the lower engine mount from Powerflex, it was interesting to pull out the factory mount and feel how soft the rubber is and compare it to the much stiffer Powerflex. I have had it installed for just over week and I am pleased with the stiffness balance to prevent excessive engine movement while also maintaining a comfortable Cabin. the only time I notice there is a difference is at Idle, you are able to feel a small vibration from the engine but it is not enough to bother me. I did not yet test the black inserts that stiffen this up further. One challenge I had was fitting the new bushing into the factory bracket, it appears the design does match the housing well enough to fit, I had to trim some of the Powerflex bushing to ensure a proper fit (see photos below). Tools you will need:
Step #2: Remove the factory bushing There are 3 torx bolts to remove. https://cimg7.ibsrv.net/gimg/www.nor...eb573ef620.jpg Step #3: Press the factory bushing out I used a press to make it easy, you could likely get this out with some elbow grease. https://cimg0.ibsrv.net/gimg/www.nor...7be1f896c9.jpg Here is the stock bushing out of the Bracket https://cimg5.ibsrv.net/gimg/www.nor...8a297295ca.jpg Step #4: Install the new bushing This should be easy but I found that the internal shape in the bracket is different from the molded Powerflex bushing. The bracket has a constant radius on one side and the other has a flattened radius. The powerflex is molded with a standard radius on both sides.. https://cimg5.ibsrv.net/gimg/www.nor...fa949f0c89.jpg https://cimg5.ibsrv.net/gimg/www.nor...79452dde87.jpg When the Powerflex is installed into the bracket it will pop back out, it is nearly impossible to install both sides and hold them in place. I decided to trim the bushing for a proper fit and function. https://cimg4.ibsrv.net/gimg/www.nor...0bfae6a077.jpg https://cimg8.ibsrv.net/gimg/www.nor...5fd2ee45a0.jpg Trimming the bushings is a challenge due to the materials resistance to abrasion and cutting. Also, after trimming the wrong side I also trimmed the right side.:sly: https://cimg0.ibsrv.net/gimg/www.nor...2b4972f920.jpg Step #5: Reinstall the bracket with the new bushing. https://cimg4.ibsrv.net/gimg/www.nor...330c835f28.jpg Step #6 Reinstall the Lower Engine Skid cover and test drive. |
Great how to, thank you. I've installed one of these on almost every F56 we have had in and never had to trim one yet so I wonder if your F54 is so new it is a little different or what, but I'll keep an eye out to see if I see that same thing in the future, but my guess is it may just be yours is so new.

I just pulled the engine mount out of my 2017 Clubman S ALL4. Crazy how sloppy and loose the stock mount was. I pressed out the bushing, thoroughly cleaned it, then reinstalled it. Then I sealed the cracks with hot glue and filled the bushing void with 80 durometer 2-part urethane. I used Smooth-On PMC-780 dry. It’s curing now - will report back later.
Here’s a video I took of the loose bushing. https://cimg8.ibsrv.net/gimg/www.nor...9852c1572.jpeg Before filling. Backside is totally sealed up. https://cimg9.ibsrv.net/gimg/www.nor...718a6ce88.jpeg After filling. |
Does anyone know how to replace the upper mount? Can someone give me some tips? I checked the videos on youtube. All of them are F55 and F56. F54 has more room between the headlight and the month location.
Thank you |
