HydraGlide Rebuild Question

#1

Post by Bigincher » Sun Sep 19, 2010 4:56 am

Last weekend I picked up a real nice old HydraGlide front end for my '52 project. Been sitting on a shelf for years. This evening I started tearing it down for a rebuild. Came apart easy enough, but the top oil seal in the slider seems to be really stuck-- almost like 'bonded' into the slider. Probably the original seal. The HD manual simply says to 'pry out the oil seal'. Well, let me tell ya, that sucker ain't just 'prying out'.
Any tips or suggestions on how to get that sucker out of there?

I know I'll probably have a few more questions as I go through this old front end. It's simple enough, but like everything, it's all about the details......

Take a pair of sidecutters and cut the seal from top to bottom through the metal edge. Grab one of the loose ends and yank the sucker out. Or, take a small chisel and knock the metal edge (rim) of the seal inward till you can grab it with a pair of pliars, channel locks or whatever. Yank it out. In this particular situation, there ain't to many rules except try not to bugger the lower leg....bosheff

that would certainly do the trick. i have something similar, more like a prybar with a point on one end.

You could heat it up a little on the outside with a propane torch and maybe that will loosen it up too.

For really tough to remove fork seals I use a slide hammer with a hook on it. Prying is not the preferred method! (Ever had to weld up the lip on a pair of sliders?) A little heat does help as hog54 mentioned. The nice part about the slide hammer is there is not side force.

Thanks for the tips, guys. There were a couple of wound-wire 'retainer rings' behind the 'seal lip' that came right out, but that's as far as it goes. Every time I try to attack it, I can see potential damage to the slider, so I stop. Robbie, I'll try a slide hammer of some kind...
Does the seal have a metal housing that mates to the inside of the slider? (for lack of better description). I assume so, and that's what Bosheff is describing. I think heat might be my next step...

Dear Bosheff,
Cut and crush always worked for me even when there were two stacked in there.

This slip-up Might confirm, to me, what I have been wondering for awhile. Are Cotten and NIGHTSHIFT one in the same? :?:

Incher,
The "wound wire" is the spring that puts tension on the inner neopreme seal lip, they all have one. And, they all have a stamped steel outer housing that gives the entire seal an outer surfcace to hold it against the inside diameter of the tube, but its THIN, and easy to cut or pry. Once you cut, or bend, or crush, that outer steel shell ring the whole thing will come out of the tube with very little effort. When using any of the tools mentioned above the main objective is to pry on the old seal and NOT the inside diameter of the tube.

It ain't that hard, just pry the old one outta there.

Dear Panhead_Kicker,
Yeah, if I can pick up bounce off the river bluffs.

I think the seal is supposed to have the spring on the oil side.
