International 300 utillity loader

after running my 300 u using loader i notice when its parked leaks out from lift cylinder drips on front tire covered in hyd oil. one lift cylinder has a rust pitted close to end i think it tore o-ring or packing loose has any body have a decent used cylinder for the IH loader for the 300 u or know what is inside what is used for seals?

Probably one hundred loaders are made that could be put on (or adapted to) a 300. if they are one way lift cylinders they are leaking at both the piston packing, and the rod packing. If two way they may just be leaking at the rod packing but are likely to be leaking at both. Almost all cylinders can be rebuilt, some very inexpensively, some not. A picture will do, but we need more info to assist you correctly. Model of loader, or make of cylinder. If in doubt take the cylinders to a hydraulic shop.
Be safe, set the bucket on a sturdy low support before removing the cylinders. Cap the hoses and cylinders before removing the pins. Jim

My 300 U does not have a loader, and with the tipped front wheels (tippped in at the bottom), I am just as glad that it doesn't have the front end weight of a loader. If you don't really need a loader, I'd consider taking it off then the tractor will be much more agile.

But I do have a Superior brand loader on a 340 U, with one way lift cylinders, and they leaked. The 340 has a better front axle and handles this loader well. So I took the cylinders to a hydraulic rebuild shop and they custom made the necessary parts, as the original parts are NLA. IIRC, the rebuild costs on each cylinder were about $250 each. Another option is to look for replacement cylinders in the Burden Surplus catalog or website, but I think they are about the same cost, and may need to have the mounting ends modified to fit your loader. I believe the hydraulic pressure created by the factory pump on the 300 is about 1800 psi (??), lower than the standard of 2500 to 3000 psi used by today's equipment. This can affect the choice of loader cylinder diameters. If you order new cylinders, look for ones with larger cylinder rods (rams) as they are less likely to bend when extended.

Good Luck!

heres a picture it has one way lift i believe it came original with the tractor the hyd hoses and cylinders have IH stamped on them

CaseIH will have seal kits. So will most hydraulic shops they are good cylinders with easy to repair mechanism. Jim
