Ford 600 hydraulic system

[gwayne919]

Well, I'm trying to help out a neighbor get their 600 Ford running after it has sat for a long while and vandalized. There was water in the transmission and it looks as if I will need to flush the tranny to remove the congealed tranny lubricant and I need to know if the lift system uses the tranny lubricant and what type of filtration is used to keep the pump from being destroyed? I've ordered the right shifter boot because there seems to be many different boots with different specs and its broken rubber was the leakage problem and drained the messy lube and will remove the top shifter cover to get at the insides to see how bad once the boot arrives and then begin the flushing process to clean it all up. It looks like removing the pump is essential. What I need to know is if there is something that I need to pay special attention to like any filter screen as there seems to be no replaceable filter. I also found a lot of sludge in the engine screen/drain plug and will probably end up pulling the pan and cleaning it as well. This 600 Ford is very simple and it'll take some money and effort to get everything right before I even think about cranking it. Help me out if you can? I've ordered a new starter because the old one has disappeared along with a replacement spin-on conversion oil filter. It already has a single-wire alternator thankfully. A complete exhaust system is needed as rust has taken its toll, but luckily the manifold is intact and might only need gaskets, but getting it running is first. This poor baby has been left out in the weather, but the crankshaft turns so it's not stuck. It surely needs some care and a roof over its head for change.
BTW, what type of gear lube and how much should this 600 need? Looking forward to hearing from my forum buddies since collectively you are much better than anything found in any parts manual unless it is an advanced piece of machinery, but not this old Ford 600.

600 has three separate reservoirs, transmission, hydraulic, and rear end. The hydraulic reservoir is under the seat. You'll find plugs for all underneath the machine. There is no filter or screen for the hydraulic. You can remove the side cover from the hydraulic reservoir and get decent access to inspect and clean.

recommended fluid is one that meets the '134' standard, it should be on the bucket.

a I&T manual is recommended, it'll help a lot as you sort thru the machine.

good luck with your project -

David

Thanks David,
The information that you sent me is appreciated. It was diffiicult to see how Ford didn't provide a hydraulic screen to keep trash out of the pump, but they must have had a reason. The CD is on the way should help me with any repairs since it is a repair manual for the 600. I ordered a shifter boot and will need to remove the top of the tranny to flush it out as a lot of water came out since the boot was rotten and allowed it in.. The engine oil pump screen filter was also filled with gunk and so it also needs flushing, I've had all of the plugs out and draining and once everything has arrived will be time to begin the flushing and refilling process. So many trannies are contaminated with water when the tractor is parked outside and the shifter boots are damaged by dry rot. Lots of work till this baby is back among the living and working, but I'm doing it as a favor for a deserving couple and they will need it in the future if for no other reason than to mow the weeds and keep the brush down. I'm no stranger to dirty work that others have created, but at least the engine is not stuck. The starter disappeared along with a lot of external parts that are luckily still available. Thanks for the information.

I just changed my hydraulic fluid again this year. It was only a
couple seasons old, but the original oil when I bought it was a
mess so I figure it will help to clean it out to change it often for
a couple years.

Anyway, drain everything well. I took the PTO
out and reached up in there and scraped as much gunk as I
could into the drain hole. I had the top cover off the lift and
scraped all the gunk out. The transmission came last, and it too
had gunk and water in it. A real mess but I used some rags to
get everything out as much as possible. I even used some
kerosene to wash some crap out and then wiped it out and let
it sit to dry out.

Instead of heavy oil, I used some hydraulic/transmission fluid
in it and it has worked just fine. I just filled it to the weep holes
and pluged it back up. That fluid works good for me winter and
summer.

It’s a messy job, but you’ll be making a tractor real happy
doing this service.

I actually have used 90-140 GL-5 gear lube and a 20% mixture of hydraulic oil in the tranny and differential and find it is okay.
