Planer maintanence question for you guys.

(1/3) > >>

A.O.:
Ok , as you know.. or maybe not.. I bought a used Jet JWP 160s 16" planer, got it all up and running "but"..

It has a set of anti kickback fingers that are on a rod on the feed end of the machine, these fingers are supposed to loosely pivot on the rod to be effective. On my machine they are very gummed up with something, pitch maybe? Anyway, I see no way to remove them to clean without a major disassembly of the machine! I do have the manual and it says nothing about them except to keep them clean!
Does anyone know how to get them out, or know of something I could spray them down with to loosten them up??
They are so gummed up its kinda hard to even start a board through the machine!


Thanks in advance!


Here's a PDF of the manual...

Best stuff I use regularly for any of that sort of thing is a mixture of ATF and kerosene, 50/50.  I use used ATF from maintenance on vehicles until I run out of it, then I'm forced to use new stuff.  But straight ATF by itself will cut through that gunk because of its high detergent properties.  Or straight kero or diesel will cut through.

So far I've used Gunscrubber, gum out choke cleaner, WD40, and WD40 silicone. Loosens them up a bit, but not enough.

I'll give it a try, dont have kerosene but I have diesel, and a couple varieties of ATF.. pretty close I'm thinking..

furu:
If that fails try acetone.  Not a big fan of it in most cases as it is hard on any thing that will dissolve but it will dissolve just about anything so it might work.

Ox:
Yep, acetone is a great solvent and dries without leaving a film.  It's the only thing I use for final prep of important surfaces like cylinder heads and such.

The different ATFs available are close enough to one another for your purpose here it simply doesn't matter - use any old thing.  But don't just use any old thing in a vehicle transmission!  The different fluids have different friction modifiers (or something like that! lol) and can act differently in different transmissions.
