brass, aluminium, steel? type of metal may help diagnois

strainer built of many magnets, that would eliminate two metals.

http://www.paccarwinchpubs.com/amfilerating/file/download/file_id/198/its a strainer with the addition of magnetic rods to help retain ferrous metals. But screens also catch anything too big to go thru them.

Thanks stumpjumper, I was going to google that this morning. You beat me to it.Paccar also has a really helpful tech support line.

How about a photo of the metal that came out of the screen..?

As you said, no large pieces. Now I guess the $64,000 question is how long has it been since that screen was last removed..? If you have no idea then I would suggest to remove the screen maybe once a month going forward (don't clean it) and take good closeup photos each time so that you can compare the way the metal is building up on the screen and the hours that the machine has operated in each case.

So based on how it operated and reading the above manual, I was thinking that the problem might be a hydraulic leak somewhere, causing the brake to fail to fully release properly. It took a lot of revs to get the winch to turn. Seemed to turn ok, just sluggish. Every once in a while you could tell it was turning against the brake.So I cleaned everything up, dumped some of the old oil back in to prime the pump, and started the tractor. Sure enough, a massive pouring oil leak between the spin on oil filter and the control valve. There is a ball check in that line, and it looks like its been removed before. The check ball is missing. Some how, the valve body has a huge port to atmosphere, and it looks like the full pump flow is gushing out of it.Anyway, suffice to say, there is no way the hydraulics could have the pressure needed to function properly.Waiting on a new check valve now...I will watch that screen though.... We pulled some of the side plates off to expose bearings and teeth. They all look good.Gotta find new control cables for that unit though. CAT wants $1500 for the three cables.....OUCH!

How many hours on the tractor and did it come from a high winch use application? aka logging, oil field, pipelines, etc. I have had winches on the rears of my deere 550 and ih 15c and they were basically adjustable tow cables for trucks, but in the oil fields and pipelines the winch might be 85% or more of the tractors total time.

IIRC on those winches the full pump flow will gush out of the dump port on the control valve when in neutral. When you move a lever to reel in or out the oil will stop coming from the dump port and pressurize the forward or reverse clutch and then start releasing the brake.

But you can see straight through the valve. Imagine a ball check valve with the ball removed. Its just a straight through hollow fitting. Thats what I have here. I can't imagine you should be able to see through it. I have to think there is something missing inside.And of course the the price for a new one is $700. It would be nice to know mine is pooched before I go ahead and order a new one, and find out mine is ok.??????

Do you have a Part Number for the valve in quesiton..?

Unfortunately there does not seem to be a breakdown of 118-6277 in any system to which I have access. According to me a new one is $478 - a bit of a difference. Have you tried Offroad Equipment for a price..?

I was hoping to find a good alternative source for this.Thanks NigeKen

Offroad will supply a genuine part (maybe a Paccar one) but their prices appear to be extremely competitive with OEM judging by the experience of many people here on HEF.

I've emailed them, we'll see what turns up.ThanksKen
