Thanks for the video. I find it a lot easier to put a screw through the area that you taped the rio into. This way the screw holds onto the seal, grab a pliers and yank on the screw, Whala, seal it out. Note: the bigger the seal the more screws you might need.

This helped a lot thank you! I'm rebuilding my Mercedes E320 engine M104 and was stuck trying to figure out a way to remove this seal. Best video I found for it. Mine is on the engine stand with the crankshaft removed so I was also able to hammer it from the inside with a chisel after bending it with a screw driver from the front. Edit: I should have checked the shop manual. It actually specifies removal using a screwdriver with a protective cloth and installation with a special tool. Still the video was helpful.

Great video. I made up a hollow drift that lets me tap fork seals into the slider housing with pretty much equal force all round the seal which is ultra critical on motorcycle fork seals for if they're the slightest bit out they'll start leaking within a few days. I used a small length of black steel tube I scrounged from a metal bin at work and dressed one end so as not to damage the seal body.

Seeing how the gasket is also leaking oil from the sides, its worth the effort to remove the remaining bolds and replace that as well. Minimal risk of damage to the housing and you have already done the hard work.

I'm not a mechanic, but I was watching this video and at the same time watching "Wheeler dealers" Haha they were doing the same thing. They used the old seal on top of the new seal to seat the new seal. Therefore, they were hitting the old seal with a soft hammer that pushes the new seal into place. Just thought I would share...

hi, sorry for delay in reply, we just got back last monday. if that works then why not ! however the springiness in rubber will often cause you to stuff up new seal when driving it in, you need a harder driver that you can control evenly. cheers

@YepThatsIt 2 жыл бұрын

hi, sometimes the old/hardened seal can wear a groove in the crankshaft. try driving seal in a bit less or bit deeper than where it sits normally ( so it sits on a new spot ) sometimes you can also shorten the spring about 5mm to make the seal lip grip a bit more. however the seal can/will wear out a bit quicker and make sure you dont cut the tapered end of spring off or you wont be able to rejoin the spring ends. cheers

Not bad fella, not bad at all, except the screw driver bit, but hey if you know what your doing then by all means use a screw driver. I have a Toyota Supra Twin Turbo 2L Auto on a J plate in Black, the car is immaculate. I've just spent almost 5,000 Pounds on a complete engine re-build, car runs like a dream now. I took the car in for the re-build 5 days before the first 3 month lock down here in the UK, I now have the car back but where it has sat around prior to the re-build and during the re-build I now have this Rear Main Oil Seal Problem. Being a Professional Drummer work is zero and when you consider the money spent on the re-build I am now skint. I don't really want to add additives to my engine oil in order to plug this leak which means dropping the Transmission, I'm worried AT-205 Re-Seal would mess up other non leaking rubber seals & gaskets. Whats your advice Fella?

@YepThatsIt 3 жыл бұрын

hi, often the seal lip will wear a slight groove in the crankshaft where it runs. you can either not push the new seal in as far or push it in deeper if possible and it will sit on a new spot and seal better. if your eng rebuilder used the old crankshaft, they may have missed that and just installed a new seal, causing your leak. if under warranty take it back as soon as possible. cheers
