Gearbox input shaft seal extraction agony no more !
Posted: Fri Jan 05, 2024 8:29 am
Hello,
Being in the midst of a chassis change I take the opportunity to change all lip seals (simmerrings) and gaskets on the engine and gearbox. It was such a pain to extract the gearbox input shaft lip seal! I just could not grab it from anywhere. I'm angry about myself to have marred the inner diameter of the front gearbox cover a bit while trying to bend the edge of the lip seal to be able to grab it with a pair of pliers. I had to touch the inner diameter of this cover a couple of 1/100th on the lathe to fix this.
Then, most importantly, in drilled and tapped M3 three holes at 120 degree on the front cover so that next time it will be a piece of cake to push out the front gearbox lip seal. I'm already looking forward to change this seal next time
I'm not saying I'm looking foward to pull the engine+geabox from the car to do it
Below is a pic of the modified front cover
