Sealing a tight fit
Sealing a tight fit
(OP)
I have an intermediate shaft in a transmission unit that goes thru a cast iron hole in the case. .0005 max gap and even with thick gear oil it leaks. I need something very thin that can get into that gap and seal it.

port the hole to accept the seal OD. see mfg web site.
in addition the shaft must be properly machined
to prevent the seal from failing & to seal properly.

Any LocTite salesman will be able to guide you through the hundreds of LocTite products, depending on your specific application parameters (heat, gap, size, ...)

For your application, you want to look at retaining compounds, for example Loctite 609 or 620 or 680.

If that bracket weren;t there, using up valuable space, I think gluing an external cap would work slick. Actually, I think with thorough de-greasing applying a fillet of RTV would work.
I'd be checking to be sure the breather isn't plugged.
There's always the "rub it with a bar of soap" trick.

any time there is jerry rigging it will never work correctly.
loctite is a temporary fix, I have encounter this type issue before.
& it just leaks again. so then you have either fix it right or live with it.
loctite will be temporary fix.

sometime it will just peel if isn't cleaned properly.
or leak but the leak would be small.
