Thanks!
My engine mount was cracked so I got a new Lemforder insert and took the whole stuff to the nearest shop to get them swapped. They were willing to press it out and press the new one in for $60. I still can`t get used to the Bay Area prices. So I decided to do it myself. It was a huge pain and I spent way more time on it than it`s worth, so probably that was not the best decision, but hindsight is always 20/20.
Heating up the aluminum housing as if it made a difference.
This is my setup: I went to autozone and rented a wheel bearing puller set that I combined with my vise.
There was a great chance that I would break the vise using this meter long extension, but actually it survived.
Everything is possible, just have to force it.
I`m stronger, told you...
For assembling I was gonna save some manpower and dropped the insert in the freezer overnight and heated the housing in the oven before the action.
It helped, it was definitely easier, still a hassle though.
Time to give it some vibration
