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.

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

  1. Keep seals clean from the time they are removed from package until they are installed.
  2. Clean the groove or bore into which the seal is to be fitted before installing the seal.
  3. Never touch the seal lip in handling. Always pick up the seal by its outer member.
  4. 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.

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.

  • I have one of your lifts, serial number 103742. It’s 1” rod and I need a seal kit for it. Please advise. Thanks!

    Thank you for reaching out!
