Engine Motor Mount

I have been looking, but have not found any writeups on diy engine mount bushing/insert removal/press. I don't have access to a hydraulic press, and have one on order, as I have been starting to experience issues going into first, and after sitting overnight, a slight "clunk" when going in reverse. Better safe than sorry for a $20.00 part.

Will a 3 prong gear puller (ie, Harbor Freight) do?

Or does anyone know of somewhere I could have bush pulled/pressed in Orlando Fl (Winter Park) area, on a Saturday?



Thanks in advance.

About any machine shop can do it. If your's is badly torn, best download and print a pic of the mount orientation. I think mine was ready overnight.

I don't really think a 3 prong will do it. I have a hydraulic press and used that to do mine.

three prong won't work on such a mount.

I used a reciprocating saw to cut the bushing shell, chiseled it a bit, and it fell out.

Heated the mount bracket in oven, put mount in freezer. Then used a sledge and a big socket to pound in a new bushing.

Somewhat of any ass pain, but it worked

you need this tool
https://www.agatools.com/tool/porsche-transmission-tools?gclid=CjwKCAjwyrvaBRACEiwAcyuzREsNte7-2NZd21nr9aCaw3-NBwwm-_VqT1E_NaOsFoHlB-a-czUxkRoCl9EQAvD_BwE
or a shop press using a tube in the correct diameter.
there is a DIY on the pelican website.
i never used the tool above (yet) but i have it, and you can borrow it if you want.

I'll be doing mine in the near future (I have the insert on my workbench) and was planning on using my vise (will also freeze the insert).

I've heard tales of using 2 sockets (one on each end) with one matching the diameter of the housing and one matching the diameter of the bushing (or combination of socket and washer on bushing side) then running a threaded rod (or bolt) through both the sockets, add nuts to both ends, tighten....and like magic, the bushing is extracted.

Never tried it, but I would first if I ever needed to do such and extraction. The only problem I see with this is potentially deforming the housing...but then again, it's such a simple idea I'm sure it doesn't work...

Hacksaw a section out of the old one and it comes right out. Vice to press new one in. Donít forget to double check orientation beforehand.

Using a socket can work, but we are talking a big freaking socket, would be easier to just take it to any shop. I replaced the entire unit, itís not expensive and you get the updated 997 carrier. One and done. I doubt I will ever have to touch it again, unless my motor comes out for some reason...

Job done

And what a PItA!

Had bush pressed at a tire shop. Paid more than I wanted $40, but it was my fifth of sixth stop finding someone that could do it.

Hindsight I prop ably should have just bitten the bullet and removed the two water hoses.
Hardest part by far was getting the top two bolts aligned onto the bracket. I also recommend taking off the bottom bracket studs off instead of just the nuts.

As the day went on, it definitely got harder to squeeze under the car.

Felt like a contortionist

Shop that swapped bush said the one he pulled was fine, but there was actually a third of the rubber missing. Car definitely feels tighter.

Patience is a must if doing this job

Guy that pressed the bush said that there was nothing wrong with the existing one....

Opinions??

Old bush:


I pondered either just filling that one with poly, OR adding poly to the new one, but for once decided to leave well enough alone and just replace it.

Not a huge difference, but noticeable, and smoother.

Yeah, looks dead. My middle mount basically fell out. Completely gone.
