Looking back at my photos, I never did properly document what I did. I really only have one photo: This is the front half of the shelter dolly, or as I got to know them when I was in the military, a "mobilizer." I apologize for the crudeness of the wiring install. This was taken after I got...

Hey Coug, I realize this is a really old posting, but I just found it today as I was (again) searching for anyone who had done an in-truck electric brake controller to air system. What was your final solution? For what it's worth, and I've forgotten to post it, I did an electric to hydraulic...

For those interested, here is the photo montage of disassembly. The original pump and the P51K1 kit The top removed. Six bolts and it comes off easy enough. The check valve is the smaller assembly behind the huge piston cylinder. I also found the inlet filter to the pump had come off; you...

Probably my last update on this. No joy at finding the proper packing washers for the piston, so I had to improvise. The place in Seattle was good enough to work with, but they had no drawings anymore or any reference material and couldn't match up my dimensions. So I found some all-rubber...

An actual Sales person from Enerpac got in touch with me today and apologized for the lack of experience in the tech and service department. He also explained that Enerpac had a big data purge in 2015 when they moved facilities and wouldn't have the info on that old of a pump. However, he did...

In what I thought might be a fortuitous turn of events, I found a tag on the second pump. After careful heating and scraping of two coats of CARC and one coat of paint, I was able to find printing and an embossed part number. These pumps are POWER-PACKER (now Enerpac) HP6001-5108, 6000 psi...

Investigation results. Looking up kit part number of KU2000 on NSN sites, I found the kit was made by a couple of different manufacturers. The NSN is 4320-00-304-3925 The manufacturers are: Actuant Corp. Komatsu America Corp. I left a message with Enerpac which is/was Actuant Corp or a...

Thank you for the pointers about CARC. I got to looking at the kit of parts last night real quick and noticed the kit for the Enerpac P51K1 is not exactly right. Some parts in the kit are correct, other parts aren't for this pump, and parts from this pump that are needed, aren't in the kit...

I'm finally getting to the teardown of the first pump. I have it all apart at this point. Next job is to try and remove three coats of CARC from the housing, two of which are flaking off badly. I'm not sure if I should sandblast or use heat and a scraper. Any recommendations? I had an evil...

I ordered up a couple of kits. I've got next week off work and this looks like a good project for a day or two. :) I'll try to post my rebuild here. Asa Jay

So a kit like this might help?: Do you have any experience rebuilding these? If so, how easy would you say it is? I've done plenty of mechanical rebuilds, so I feel this falls in my wheelhouse; just looking for any "gotchas." :) Thank you, Asa Jay

I obtained an M720 at auction a couple years ago and it sat idle until today when I wanted to hook it up to an S280 shelter I have. However, I found both hydraulic pumps to be non-operational, so I didn't dare lower it to the ground to start with. Both pumps move easily without ever building...

It takes a lot of skill (and practice) to properly back any of these articulating dollys with a deuce of 5-ton. However, I got to thinking about "backing up" yesterday after I rigged up the dolly with the cargo straps. And actually, once I got home, I did back it up where I wanted it, pretty...

That's exactly it. How do we get the moderators to boost that to top of thread and make it sticky? Good photos by the way. :) Asa Jay

Picked up my very first M720 yesterday. Drove from Spokane to Tacoma WA to pick-up. Based on testimony here, I brought ratcheting cargo straps with me to fix the draw-bar in place. Once we had the draw bar in place, we found the left wheel was toed out. The tie-rod was bent, so we adjusted...

Guyfang, Thank you for the advice. Removing the glass ball has not affected starting, even in cold weather. I use the Run and Battle Short switches to prime the system and it starts right up. I will add the electric fuel pumps to the list of things to look at, clean and/or replace. The knob...

I just spoke with a local diesel pump repair house. They say this could be due to a governor going bad in the pump or air getting into the lines. Based on the age of the generator and the look of some of the fuel lines, I'm going to go with replacing all the rubber hoses between the day-tank...

After removing the glass-ball fitting and replacing it with a straight through non-restricted fitting, I've been able to get my MEP-005 to start and run. But now I can't get it to stay at a consistent rpm. The fuel appears to be clean. I've taken the top of the injector pump (IP) off and it...

The hour meter shows 1609. It was used by the local Forest service and Department of Emergency Services for a while and then sat for years unused. It ran alright for at least half an hour last night, maybe longer before I shut it down. Temps are below freezing in Eastern Washington right now...
