TO-20 Hydraulic Control Lever friction disk

jwinders · Aug 16, 2015

I am trying to replace the friction disk on my 51 and I can't get the circular part that the disc goes under off! I have been messing with it for 45 minutes now and I can't seem to figure it out.

You may need to use a jaw type puller or a couple of flat screwdrivers to get some pressure behind it and tap the castle nut to pop it open/off.

The castle nut is off but the part the lever screws into won't budge. Is there a trick to it or something?

Well no trick but it is on a key and probably hasn't been off in decades. Here is a picture from the parts manual

Ok I didn't want to break anything trying to get it off but now that I know it's supposed to come off I can get a little more forceful with it. Thank you for the information.

Some rust penetrant will help, maybe a little heat.

That piece is pot metal, so take it a little easy with it. As said before, a little heat would help.

Not just pot metal but aluminum. I added heat once and had a molten mess at 500F.
