Don't know if I qualify as one of the smart guys or not, but I have two log splitters, a craftsman that my dad bought in the late 70"s that's split a few hundred cords and still going strong, Its on its 3rd engine but still has original ram and valve, the other a three point recently built for...

well shortly after my last post I got on the internet and called every tractor salvage yard in the country looking for a used hst, and not having much luck, then called an outfit in Riverdale, Ca. and he said no, but would put it on the hot line, then called me back 30 minutes later and said he...

rbareron I tried to come up with the test fittings from the link you posted, but figured out Kubota uses a deep probe type fitting to test the hst as shown in the wsm. I was told that using standard size fittings would not provide a accurate reading so then I just decided to take it to the...

Ok, I went and picked up tractor at dealer today, Service writer gave me a break and charged me 6 hrs. labor for pressure test, still alot but oh well it is what it is and I appreciate them doing it, I know how it goes in the shop, I am no stranger to this, as I deal with heavy equipment repair...

Update: I was unable to get the correct fittings to tap into the hst for pressure test, so I dropped it off at a Kubota dealer 3 weeks ago and they just now got to it, and it aint good. The hst failed, along with the control valve for 3 point, and the charge pump is putting out a little over...

I have the same 4672 backhoe on my b2150. They are rated for 6' , but will not go that deep. 5' digging max, and 4' comfortably.

you are absolutely correct rbargeron, I already called the local kubota dealer, about a 100 miles away, and they said about two weeks out, they are swamped, but I will try a couple of closer shops, JD, and new holland are close by and I don't see why they could not do it, and if nothing else I...

I got the tractor back together today, and no improvement on its performance, I am bummed, But at least I don't have a lot of money invested in the repair, yet, just a lot of time. So I guess I'll have to tear it back down again, but this time at least I know where to split it, at the bell...

I would assume the tab on shaft 100 should fit in 080, no way to see other than remove trans case,

working on reassembly, I got new gaskets, pin and some other stuff ordered from kubota, I decided to polish up the valve plates and hope for the best. but first things first, I made a rookie mistake when splitting the tractor, I split it between the rear differential and transmission and...

took both plates to the local machine shop and he highly suggested not to resurface, being the fact that plate thickness is critical since the pump is in a fixed position against the plates, pump is held in the swash plate by retainer plate and snap ring. therefor machining just the bare minimum...

OK, here is some pics hopefully you can blow them up to see better detail, the kubota tech, gave me some tips on bench testing the cylinders, kind of a generic way of doing it, but mine passed the test. The one valve plate is still questionable, I might see about taking it to a machine shop to...

That's exactly what I did with the valve plates. I started with 600 and worked up to 1000 grit. I will post some before and after pics along with some others. I am not seeing any further damage, but working on cleaning everything up. The pin did shear and break and left some scarring on the...

One valve plate is 500. bucks, the other is around 150 or so, They look to only have slight wear. so why not try to clean them up. As you can see in the pic, the piston pump valve plate has some erosion but still plenty of surface wear left, and that's the expensive one.

I put my parts in a box and took them to the Kubpta dealer, I don't have the tools are capability of measuring these kind of tolerance. The Kubota tech. said the sheered dowel pin on the fixed motor cylinder swash plate was the main cause of the week power, and the heat and wear just escalated...

I removed pump motor and found the dowel pin sheared and scared up the housing a little, I don't know if this is a cause of my loosing hydraulic pressure, along with the piston valve plate, but I'm sure it don't help, The rest looks good to me, the pistons fit snug in the bores and I will check...

thanks and good eye, I really need my cheaters on to give these parts a good visual, I read that post on TBN, all 13 pages and that was a source of great information, I really enjoyed reading that, thanks for sharing it, I will have some time to remove the piston motor and pump this afternoon...

thanks W&f, I did down load a manual from www.servicemanualvault.com its ok I guess, but if you know of a better one I would be happy to see it, the one I have the pics are of poor quality and a some of it is fairly generic,

I got my tractor split and split the hydro unit today, thought I would post a few pics, I did notice valve plates were discolored and fine scratches, I haven't got the piston pump and motor out yet but will check them as well, I really don't have an eye for this sort of thing but welcome any...

Thanks for the reply W & F , So I have checked on a replacement hydro from dealer and the are no longer available and parts are getting scarce. And they won't deal with rebuilding one. I checked my local kubota dealer and a couple others and same thing. Some parts are available like charge pump...
