If you're looking for other parts, you can to save time, or browse through all of our Allis Chalmers tractor parts on the page. I told my wife the other day that I was going to get a gauge and maybe with the help available here I can find out the problem and fix it myself.
Brand: Aftermarket Allis Chalmer Oliver White Type: Hydraulics, Power Steering Parts, Hyd. I will look into replacing the existing. You have a pressure gauge - the gauge and wrenches should be all you need to set the relief if you disassemble it, find a problem, and solve it. The strength of the front ends on the 5040 should handle a loader without problems. Are you sure you're filling the correct compartment?? I think I will pull the relief valve when I get a chance and see if there is anything obvious.
Hydraulic pumps, power steering pumps, and connecting accessories. I hope he does better with other customers than he did with me. I have been fooled by them before in the belly of a Massey Ferguson. I think it has to be between the transmission reservoir and the pump. Is your hydraulic pump mounted on the side of the engine and does it have a suction line that goes to the sump which I assume is the transmission housing so the fluid level is lower than the pump? I don't have an easy way to check the flow but it seems to me that what I need is a new hydraulic pump. Before we started all of this I had to run the tractor at 2400 rpm and it would just barely pull the digger out of the ground. Drawbars, levelling boxes, lift arms, draft sensing springs, and internal parts.
We are always listing new tractor parts online for many different hydraulic pump models, and parts not listed in the catalog yet may still be available by from us directly. The feed line comes from the bottom of the transmission, goes through the screen, on to the pump and back to the hydraulic remote control valve. None of these trademark holders are affiliated with Yesterday's Tractor Co. Hydraulic pressure pushes on the poppet until it overcomes the spring pressure. The relief valve could have some trash in it. Working on how to post them: Thank you for reading and any ideas that you can share.
See our page for information about ordering over the phone, and our current shipping and return policies. Thank you all very much for your input and info. Gear shifter for 5040, shifter rails, forks, and knobs, also. I didn't know that the pumps had aluminum housings. Any and all advice is appreciated. Fuel injection pumps, injectors, and fuel transfer pumps! I'm inspecting the drain valve and pressure relief safety valve. New instrument panels-including bezel, all guages, warning lights, and associated wiring-for 5040 models! I have pics with notes on them.
Filter maintenence packages for your 5040, 5045, or 5050 tractor--buy the entire set by clicking. We did this flow test with the old screen in the system. I think the problem is either with the relief valve or the pump. It is just raising the empty bed. Based on the numbers it really looks like 1 of 2 of J J's items is your problem.
Our website is not just an online store. I have the new pump that I ordered and it looks like it will fit the tractor if I need to change it but I would just as soon not change it if I don't have to. The variation was due to me varying the rpms of the tractor, not me making any adjustments. The statement you have from the service manual indicates a cartridge relief that is not adjustable and cannot be disassembled to clean and inspect, but you might be able to spot something unusual like a cracked part or piece of metal stuck in the valve. If it is a gear pump like I suspect, the solution is the one you mention - replace. Or does the steering have it's own reservoir tank? We used a paper filter on combines but even then we didn't figure on even a 5,000 hour life for our gear pumps.
Do not use regular grease its not flowable enough. If it is out of specs you replace it. New instrument panels-including bezel, all guages, warning lights, and associated wiring-for 5040, 5045, and 5050 models! The pump is mounted on the front of the engine and gets its power from the timing gear on the engine. One thing I don't know, is it possible for air to get into the system in the pump itself? I put a 5000 gauge on one of the remotes and this is what I got. Might be a bad seal on the cover allowing it to suck air instead of oil.
