"Inside-out" seal

[Phil Waterman]

Hi All

This thread has bin ringing a bell, that the topic had come up before with some other thoughts here is the link,
http://www.mapleleafup.net/forums/sh...ght=tilt+angle

Having a problem copying the link but think it works.

If we are indeed talking about same seals I have been operating one of my trucks without the seal for years without any sign of gear lube getting through the bearings to the brakes. You really would have to have the truck on a steep cross slope for an extend period of time.

Cheers Phil

Yes, this is on the spring mount. It is not a wheel hub. I thought an o-ring might work because there is no high-speed rotation. It only rocks back and forth a short distance, and at low speed compared to a wheel hub. An o-ring should at least be better than the felt washer that was originally used in this application. (But apparently the felt washer wasn't good enough because it was replaced by the lip seal.)

The speedy-sleeves I've seen won't work on such a narrow surface. It seems logical that there should be a style that will work, so I should look for a more comprehensive catalogue.

We have far more wear on those trunnion mounts than on a normal wheel bearing. The short travel back and forth seems to be very hard on the bearings and just as bad on the shafts themselves. Again though, that is on the MLVW...I can't speak to the vehicle you are working on.
