(W) 450 hydraulic problems, need some help please

Couple years ago, friend of mine sold his acreage. Moved to town. Get a call, I know your into old red tractors. I left one at my old place, its free. No idea what I was getting, took truck & trailer. Told it died where its sitting. Its a 1957 W450 with a front end loader. So I winched it onto the trailer & towed it home 18 miles. Cut the loader off, took to dump. It wasn't worth saving, already have an IH 560D loader tractor. My shop is finally done, towed the W450 inside.

The wiring of the W450 is a rat's nest. Replaced the coil & ran couple wires to make it run. Got engine to turn over & have spark. Poured gas in the cylinders, its came to life. Cleaned sediment bowl out, same as gas tank. Poured some gas into tank, started to run out of carb. Then it quit leaking. It the button & came to life!

Great I thought, this is going to be the snowblower tractor. Found a 4ft front mount snowblower of local ads. Finally got brackets made up last night. It will barely move a 3" x 12 ram to move the blower. I can just push the blower around, so its not that heavy. When New Holland sold this snowblower for there tractors, ram was only a 2" ram.

The engine loads up when trying to move the ram, both lines get smoking hot when using hydraulics. Oil level is good, checked that. Going to take screen out of bottom of tank. I read about screen & orifice in the safety/regulator valve. Where is this? Would that be my problem? Not sure how this tractor ran a loader with 4 rams. But its been sitting for couple years now.

Thanks for any help.

Never been around a W model but assume Farmall system to be the same. You say pump loads up when trying to lift so this tells me it is not loading up when in neutral. This also tells me that problem is not in the regulator valve as if that was the case pump would be loading up in neutral also. Sounds like you have a restriction between valve and cylinder or load exceeds capability of system which does not sound possible from your description of problem. The Farmall models used a quick coupler that could be screwed partially apart for hooking up hose under pressure. If that is partially unscrewed that would cause your problem. At any rate, time to take the hose off at cyl to check for full flow to cyl and back from cylinder.

First time I saw one of those couplers partially unscrewed, local know it all brought the pump off his friends tractor into to me to look at it. Well, just from looking at pump on the bench and listening to his complaint I said something else is your problem. He found the coupler problem. This was way back before we even had a flow rater to hook up to test flow.

Thanks Pete, you were right about a restriction. I was going to get rid of the couplers & just run the hose from the factory spool to the ram. The ram is brand new, but the threads are npt, same as the hoses. No idea where they came from, but used couple npt swivel fittings. I removed the lines from the rams, noticed oil spraying out fine mist. Took out the swivel fittings, they have a made in restriction. The hole is about the size of pin. No wonder the ram was slow, & system was overheating. Installed the hose without npt fittings, ram goes up/down like its suppose to. Can even lift the tires off the ground. I find nothing tougher to fix than a self induced problem. Thanks again Pete, gave me something to look for.
