MIT-91273-30220 Forklift Cylinder Seal Kit Fits Mitsubishi - Aftermarket Replacement

Is a hydraulic cylinder on your Mitsubishi leaking at the rod, drifting under load, or losing power? Worn seals are almost always the cause, and resealing the cylinder brings it back to full holding force for a fraction of the cost of a new or rebuilt cylinder.

This Beaver Island Parts Company kit is an aftermarket replacement for Mitsubishi seal kit MIT-91273-30220. Kit contents: 2pc wiper and 3pc oring seals.

Kit Details

What It Fits

Replaces Mitsubishi part number MIT-91273-30220. Always confirm the kit number against your machine's parts book or the stamping on the cylinder, and measure the rod and bore if the cylinder has been rebuilt before.

You Can Do This Repair

A cylinder reseal is well within reach of a careful owner with a shop. Lower or block every implement and relieve pressure, then remove the cylinder or support it securely. Unthread the gland, pull the rod and piston, and lay out the old seals in order as a reference. Clean every groove, inspect the rod and bore for scoring, then install the new seals with a blunt seal pick (never a screwdriver). Warming polyurethane seals in hot water makes them easier to seat. Lubricate everything with clean hydraulic oil and torque the piston nut and gland to spec.

Pro Tip: Photograph the seal stack before you remove it, and keep the old seals until the cylinder is back in service. Matching profiles side by side removes all the guesswork.
