white 2-105 hydraulics heating up

Hi everyone i'm looking for some help on my white 105. Just had the injection pump redone now i'm digging into the hydraulics that have been giving me problems before hay season gets here. The problem is that the hydraulics heat up as the tractor runs. I've read through several posts on here for the same issues and I've done a few things so far but no luck. I've checked pressure at the remotes and I have 2200 psi. I took the relief valve out and cleaned it up, it was pretty clean but I noticed the shims were a little beat up so I put in some new ones and added 3, there were 4 in there already. I've read about doing a case drain test to see if the main pump is bad but i'm not sure exactly what line you take off to catch the fluid? I have an IT manual but it doesn't give a lot of detail on troubleshooting the hydraulics other that the protractor test to check pump stroke. The hydraulics work fine and I can run the 660 baler all day but as things heat up the gate on the baler gets jerky and slow. any help would be appreciated, thanks

I forgot to add that there is quite a buzzing or clicking sound coming from the compensator. could this be my issue?

You have e-mail?

My system getting hot since last year too. The implement cylinder gets hot to the touch. Taking it in to the shop soon.

The pump is probably pumping constantly, you need to reset your compensator valve so the pump destrokes when there is no call for flow. They do also wear out, used to stock a couple in case the techs couldn't get it to work correctly.

There are three lines to the pump. A big one going in the side,a big one coming out the other side and a little one in the top. The little one is the case drain. Get it warmed up,shut it off and take that line off. Clamp a hose to the fitting on the pump,put the other end in a bucket and have somebody start the tractor up and rev it up about half throttle or so. A quart of oil every 15 seconds is what's considered normal for it to leak off. My 2-135 was heating up and when I did the case drain test,it filled a 5 gallon bucket in 50 seconds. I put a new pump on it and that took care of it.

Randy, is the procedure the same for a 2-155? Thanks, gm

Just did the test got 2.5 gallons in 30 seconds. Would this indicate pump is shot? If so are they rebuildable? I have a few good hydraulic shops local.

That is way too much! Send me an e-mail with phone number. J.

Yes.
