rear engine seal

[Joel D]

On boxxer 421 came off. Just finished a job and smelled oil. Then noticed rear seal is out and floating on shaft. Can i push it back on and add some high heat engine sealant to get me thru a few days? I was thinking of rigging up something like some flat plates with clamps to hold the seal on. Thanks

did the seal egg shape...did the spring invert....do you know why it walk off...normally they are tapped in there pretty tight......

Looks good. I can just about pop it on by hand. Just have to come up with a way to get the last little bit.

Joel;

It takes a special oil-resistant silicone sealant to withstand the heat.

It is usually Black in Color at the auto supply.

If you can clean both surfaces with solvent, it should hold for a while.

I would put the high temp sealant on it and push it back in as long as it is not damaged...let it set up over night and add oil in the am...this is not 100% ..so keep a good eye on it.....there has to be a reason it is popping out.....

Well i already popped it in with a pry bar and flat piece of metal. I should have waited and read this first. It had been leaking a little for a while. I used to see the edge of the seal sticking out past the engine. I just thought thats how it was supposed to be. Now its in slightly after pushing it on which means its been working its way out for a long time. I ran it a few minutes and no leak at all. Ill have to keep an eye on it.

my Briggs did that and I just pushed it back in. It would pop out periodically and I would push it back in. I finally just replaced the motor. I didn't try any adhesives just force.

sometimes if you have one that keeps walking itself out ...you can put a little bit of high temp sealant around the edges and pop it back in...let it set up and it will help keep it in place.........

My Briggs did that once and I ordered a new seal. Not knowing any better , I put the new one in and it lasted until I sold that unit a couple years later,

When you replace it make sure you get one from the manufacturer not Napa...don't ask how I know that!

Temp fix.. Can be done as you describe, but repair it ASAP.

So you are saying it failed the day you transferred it to the new owner?

There is a tool that will allow you to drive it in square and secure without damaging it. Like a large socket, but it presses against the metal portion of the seal.
