Such as these... https://www.surpluscenter.com/shop.axd/Search?keywords=+hydraulic+pump&page_no=1&page_length=9999 or even a simple repair kit.

roadapples 6,983 #6 Posted September 29, 2019 I had my original pump apart to replace a seal. I know nothing lasts forever but not much to wear out. Only a few moving parts.... 1 Share this post Link to post Share on other sites

You would need to make sure the cylinders are all good as well as the lines. You can wrap up some money quick fixing those items. Randy Share this post Link to post Share on other sites
wallfish 18,244 #10 Posted September 29, 2019 Not a bad price considering they don't come up for sale very often. It's not very difficult to change the hydraulic pump depending on the location and the fittings used. Here's a link to a pump you can use. These are a recommended pump from PF Engineering for building your own loader and I use the same one for my backhoe. https://northernhydraulics.net/catalog/haldex-barnes/high-pressure-hydraulic-gear-pump-.517-ci-haldexconcentric-10567-1752.html It would be difficult to check the cylinders and lines for leaks without the pump working to supply fluid pressure but look for dents and damage on the cylinder walls and ask the seller lots of questions. Leaks would show around the fittings and or rods unless it's been cleaned off. 1 Share this post Link to post Share on other sites
jammankel 24 #11 Posted September 30, 2019 i heard back from th guy he says he doesnt know exactly what is making it so the bucket isnt working so my question is are the valves for bucket control notorious for going bad or it the pump more likely to be bad Share this post Link to post Share on other sites
jammankel 24 #12 Posted September 30, 2019 and would it fit on a 6x10 trailer Share this post Link to post Share on other sites

Let his settle out overnight then gently decant, now look for brass particles that may have accumulated if the pump has an aluminum case how much aluminum particles showed up/ Brass particles would come from thrust washers and bushings, aluminum from a worn pump casing. If the pump is driven by a magnetic type pto clutch is it fully engaging, belt slipping, oil filter clogged, has the oil supply line to the hydraulic pump collapsed internally .

wallfish 18,244 #14 Posted September 30, 2019 Neither are notorious for going bad so... That certainly doesn't mean they can't. Poor maintenance can cause issues with hydraulics. Could be any number of things from simple (belt off or missing) to more involved (bad pump) but it's not an overly complex system. There's no magic answer with what's wrong without looking it over first. Hydraulic parts can get expensive but a pump is $230 (linked above) and maybe the same for a new valve. here's a link to a few valves which can be used https://www.surpluscenter.com/Hydraulics/Hydraulic-Valves/Directional-Control-Valves/?page_no=1&fq=ATR_Spools:2&fq=ATR_Max_Flow:0\+to\+10\+GPM Yes, it will fit on a 10 ft trailer but back it in and you can raise the bucket if it doesn't fit with the gate up. Even though the hydraulics are not operating, pull the lift lever and you can manually raise the bucket. You might need help but I can lift my bucket manually using a bungie cord to hold the lever open on the valve. 1 Share this post Link to post Share on other sites

wallfish 18,244 #16 Posted September 30, 2019 If it detents and stays there but it will also float down. Mine stays up in position with just the lift open and will drift down very slowly. Gives time to get out the way and lift the gate or secure it up. 1 Share this post Link to post Share on other sites
Skipper 1,789 #17 Posted September 30, 2019 If it cant be tested, I would price it as needing all hydraulics replaced. 1 Share this post Link to post Share on other sites

jammankel 24 #19 Posted October 1, 2019 (edited) im now a proud owner of a 1975 d-180 with a ark 550 front end loader that currently has no issues(the guy didn't know how to adjust the PTO clutch so it was slipping when you put the pump under-load). whats your guy's opinions of the k482 motor? picture will come later Edited October 1, 2019 by jammankel 2 Share this post Link to post Share on other sites
pfrederi 18,718 #20 Posted October 2, 2019 They were high quality industrial engines. only problem now is parts are getting hard to come by. Change the oil an filter regularly and keep all the cooing tins in place. should last a long time. 1 Share this post Link to post Share on other sites

Those big twins, the 18 & 20hp are great engines (its a Kohler, aint it??) but, as mentioned parts are getting scarce - pistons, rings, gaskets, valves are readily available but crankshaft & rods .... not good, if lucky maybe find good used. Tend to it faithfully - oil change, fins clean, etc and it'll go a long time. 1 Share this post Link to post Share on other sites
