Little 982 help?
 
My implement lift isn't lifting my 442 3 point tiller. Historically, after a bit of use it would get slow, but now it will only lift an inch or so and that's it. I've read some threads and checked for issues within the 'lift line', but doesn't look like any broke welds or roll pins. I can stand on the 3 pt lift arms and it lifts me easily. I went thru my service manual and it refers to pressure testing/shimming the implement lift valve, but the service manual refers to the 'specs' for the info on shimming, which I don't seem to have? There is less than 10 hours on the hydro fluid, and the tractor has no issues moving forward or reverse. I took the center cover off and watched the cylinder move thru it's entire motion with no weight on the lift, but when the tiller is hooked up I can see the cylinder stall. No leaks either. Thanks!

You make NO mention of the Hydro Filter (923-3014). Is that new also ?? :bigthink:

Yes, same hours as fluid,

What kind of Pump Pressure do you have ?? :bigthink:

I just went through a very similar issue with my 1882. Two things you need to check are, your pump pressure like Roland said, and if something is bypassing. If your pressure is good, run the hydraulics for a while working it, or trying to lift. Look for what component gets too hot to touch. If something is bypassing, it will get hot pretty quickly. If pressure is not good, relief valve shimming may be necessary.

No gauge yet to check the pressure, and I understand from the Service Manual that it should be between 700 & 900psi. Again, they mention shimming, but refer to it in the specs that I don't seem to have. So, even if my hunch is right and the pressure is low, I don't have the info on how to correct it?

Every .015 shim gives an additional #100 pressure.
A small washer works just as good as a "special shim"

Unless you know pressures, one can speculate all day long.

If you own anything with any sort of hydraulic system a gauge, a couple hoses, and a few adapters, are really something you should own. It is a very inexpensive tool to have in the garage. Call a local hydraulic guy, should be under 50 bucks.. more like 30$...

When I got mine I figured out a grease gun hose works perfectly for this. It's already 1/8" NPT. I bought a 300 and 1000 PSI guage from my hydraulic shop for $65. A couple bushings and a pipe nipple for a couple bucks more and I had a "kit" just for the Cubs! I used a metal paper hole punch that I "borrowed" from my wife to make some shims out of a tin can lid. Worked awesome!
