04651-31580-71 Toyota Lift Cylinder Overhaul Kit LH for 5FD

Overview

The 04651-31580-71 CYLINDER O/H KIT, LIFT, LH is a Toyota overhaul kit for the left-hand lift cylinder on selected Toyota forklift trucks. Lift cylinders work under constant hydraulic pressure and heavy load cycles, so their internal seals gradually harden, wear and lose the ability to hold pressure. Typical symptoms include slow or drifting mast lift, oil weeping around the cylinder gland, and reduced lifting performance. Fitting this overhaul kit replaces the worn sealing components so the cylinder can once again lift, hold and lower loads smoothly and reliably. The kit is referenced against the original Toyota part number 04651-31580-71, making it straightforward to match against your cylinder and parts book.

Compatibility

The 04651-31580-71 for 3FD80 and the other listed trucks covers two Toyota forklift families:

• 3FD / 3FDE series — covering the 3FD80 together with the 3FDE60 and 3FDE70 models
• 5FD 50-70 series — covering the 5FD50, 5FD60 and 5FD70, including the 50-5FD60 and 50-5FD70 variants

Because cylinder specifications can change within a series, always confirm the number on your existing lift cylinder or check your truck’s parts manual before ordering. If you are unsure whether the 04651-31580-71 kit matches your machine, send us your model and serial number and our team will help verify fitment.

Quality and Reliability

A lift cylinder overhaul is only worth doing once, so the sealing components need to hold up under daily material handling work. This Toyota lift cylinder overhaul kit is supplied to match the original 04651-31580-71 specification for the left-hand lift cylinder. A correctly rebuilt cylinder maintains system pressure, resists leakage, and helps the mast deliver consistent lift speed and load control — supporting both productivity and safety in the yard, on the dock and on the loading ramp.

Installation and Maintenance Tips

• Release all mast load and hydraulic pressure, then safely support the mast before disconnecting any lines.
• Clean the cylinder thoroughly before disassembly so contaminants cannot enter the hydraulic system.
• Inspect the bore, rod and gland threads for scoring, rust or pitting; polish or replace damaged parts before reassembly.
• Lubricate the new seals with clean hydraulic fluid and fit them carefully to avoid nicks to the sealing lips.
• Reassemble to Toyota torque specifications, refill and bleed the hydraulic circuit, then cycle the lift and check for leaks and drift.
• If the right-hand cylinder shows similar wear, overhauling both lift cylinders at the same time helps keep mast movement even.
