Today, after much help from this board concerning my distributor, I got my $200.00 8N running. However, I discovered the hydraulics don't work, and the clutch is still stuck. I had the PTO engaged and tried it with the draft control lever in the up and down positions. Can ya'll give me an idea where to start looking for the problem. I've never been inside the hydraulics and any info ya'll can spare will be GREATLY appreciated!

Thanks,
Tommy

Feller' Texan Steve...I'm in Nacogdoches. It has a good bit of fluid in it and it doesn't appear to have any water in it, although I imagine it does because it sat outside for many years.
The pto does turn. Tomorrow, I'll change the fluid and if that doesn't do anything, I'll take a peek inside.

Thanks!!
Tommy

Hellp fellow Texan. Where? I'm in San Antone.

First thing to check is hyd fluid level. No fluid, no hyds. Check the dipstick. Fill if necessary although you've gotta guess what fluid's in there. 90 wt mineral oil or 134d New Holland. If it works (that is it'll hold up to 800 pounds - less if your implement weighs less - for a full minute and then raise and lower it a couple more times) then drain fluid and refill with New Holland 134d (others will diasgree on which fluid, but I'm a Texan and ya oughtta agree with me!).

If not, then hyd pump is probably bad. although I haven't seen it, there is a hyd rebuild video on this and other sites which you ought to buy unless you're already a good mechanic and can figure stuff out. A rebuild is a 1/2 day job (sans frozen bolts), coupla busted knuckles, and a few cheap and readily available parts.

Sorry I can't hang around. Gotta saloon waitin' fer me!

Tom, is the pto actually turning? Is the oil full and clean? If you can answer yes to both of those Questions I think I would next pull the side cover (the one with dipstick) and see if there is oil being circulated inside (with tractor running pto engaged). Search the archives, there is lots of info on this subject Then get back to us with what you find. If the tractor has been sitting for a long time could be stuck valves in the pump. If it has been sitting with water in it and froze it could be a busted pump. Hope this helps. Allen (;^)
