How do I remove my hydraulic pump?

[California]

Before you build a puller - see if you can get a pair of pry bars or claw hammers behind it to get a stronger push. Do you have anything like these you could use? But it sounds like you are going to end up using a puller.

And I'll repeat what everyone's saying, work some PB Blaster or other penetrant into it, hammering on it a little to get penetrant back in the tight spots where its needed.

Any suggestions on the best outlet for PB Blaster? I've not seen it at Home Depot....Tim

Look HERE

I expect any auto parts store that sells primarily to shops (not Kragen etc) can sell you a suitable penetrant.

JB 80 also works very well. My local NAPA sells it.

Update: Squirted in lotsa lube, waited overnight. Tied the pump to a tree and tried to drive forward, no good. Clamped on a pipewrench and tried to turn the thing around, won't come off.

My assessment: it is rusted solid together, but good. Next plan of attack: I drilled 3 holes in the pump mount plate and will see if I can put 3 threaded 1/2" rods through them, then back out nuts to push to plate and the pump off the shaft. Should this fail (I expect as much), final attack will involve the 3" cut-off wheel and a delicate effort not to harm the shaft....

Photos tomorow.

How come people don't list where they live in their profile? Not looking for a street address, just a general area. So many times I try to help people find what they need locally, but they don't list where they live so I can't send them to a local place that has what they need.

Tim, keep in mind the PTO shaft is a splined shaft (male) the pump coupler is splined (female) you will not turn it with a pipewrench. DO NOT have the PTO engaged during any attempt to remove. You need to somehow tap this off, or give waynecountyhose some more info, he can help! Maybe visit his website.

I think some folks are apprehensive about to much info, I agree a general area is very usefull, when one hears of all the scams and internet nightmares they get very nervous!

By the way ... great website!

If you have the cross pin tapped all the way in, flush, you may have gone too far. What you need to do is to get the cross pin moving freely across the pto shaft, there will be one sweet spot, where the notch in the pto shaft is, this is where you want the cross pin to be, when you are trying to remove the pump. If you have it in too far, it's just as stuck as if it were all the way out!

Very well said, and good point!
