Maintenance

HYDRAULIC CYLINDERS
INSPECTION AND MAINTENANCE:
Periodically check all hydraulic system connections to insure a leak-free condition. Also, be certain to maintain proper fluid levels in the tractor hydraulic system as in accordance with the method and frequency recommended in the tractor operator’s manual. Use only hydraulic fluids recommended for your tractor hydraulic system by the manufacturer.

Keep hydraulic system clean. Be certain to maintain recommended oil filter service intervals. All internal surfaces of the hydraulic system on your loader have been factory cleaned, inspected, and plugged with protective caps prior to shipment. Be certain all protective caps are securely in place until hydraulic system assembly is completed.

Care must be taken with your loader cylinders. Nicks, scratches, rust or other shaft damage can cause seal damage resulting in cylinder leakage and poor performance.

IMPORTANT:
Read these service tips before beginning assembly of cylinder gland or piston.

Keep seals clean from the time they are removed from package until they are installed.
Clean the groove or bore into which the seal is to be fitted before installing the seal.
Never touch the seal lip in handling. Always pick up the seal by its outer member.
Inspect each seal lip carefully for nicks, scratches, and dirt at time of installation. If dirty, use a soft, clean cloth and carefully wipe off seal. DO NOT wipe seal with fingers as this only imbeds dirt in the seal.

Never clean rubber related seals with a mineral based solvent! Clean rubber seals in denatured alcohol or non-mineral based solvents only.

NOTE:
Seals can be made more pliable and easier to install, if first heated in hydraulic oil to 160 degrees F. Never use direct heat on any seals.

Worked great for me, a novice, but Army guy that can…

First I would like to thank the tech gentleman that suggested I give just the parts kit a try, I believe his name was Mike😬

So yes, the large white U-cup seals for the piston were a bit of a challenge, but I learned while do a secret that helps beyond the hot water. I did these in the kitchen so that I could rest the piston on it’s side with one end at a time hanging just over the edge of the counter. You will need two things to get this done: one, a man or manly son to press down on the U-cup as you work in onto the piston as this prevents it creeping back off, whilst you attempt to continue around the seal. And two, a straight pick tool or old school ice pick type device.

After I heated the U-cups in hot/boiling water for a few minutes, one at a time so I would not forget or overheat the second cup. I then pressed down into the grove a portion of the cup, with my thin pick tool between the cup and the piston. This will be the guide tool to run the remaining cup up over the piston and into the cup’s groove while working your way around the piston. Self explanitory, the additional male helper pushes down with his thumbs on the cup you get into the groove, while you focus on moving the pick tool forward. HERE IS THE MASSIVE TRICK TO GETTING THIS TO WORK. I tried to simply muscle the pick tool to force the cup up and into the groove, not so much. THE KEY IS not just press the pick tool, but burst-push the pick tool with your thumb in short, high effort attacks rather than constant pushing. There is a HUGE effective difference between the two techniques. I was failing being gently, and MAGIC HAPPENED when I grunted into it like a rabbit punch with my thumb. Just know, you can do this repair. I will be doing my other two cylinders down the road and feel that I could actually do this to help someone else out.

Thanks a ton Ag Parts Direct! I wish you had stuck one of your Sioux oval stickers in my box, like the one you stuck over the taped lid. I would have put it somewhere for others to see. Oh and, my tractor works like a brand new rig!

Best regards,

Jeff Skeete

Good rebuild seal kit for 1.75" Cylinder & 1.0" shaft

The kit had everything needed to rebuild my cylinder with the exception of the seal that goes on the end of the cylinder. It fit the cylinder but it would not go on the 1" shaft.
