04431-30091-71 Toyota Rear Axle Cylinder Overhaul Kit 3FD50

Overview

The 04431-30091-71 CYLINDER O/H KIT, REAR AXLE is a Toyota overhaul kit used to rebuild the rear axle cylinder on a range of heavy-duty Toyota forklifts. The rear axle cylinder is a wear item: over time its internal seals harden and lose their ability to hold pressure, showing up as a soft pedal, weak braking or fluid leaks. Fitting a fresh overhaul kit restores the cylinder to proper working condition and is far more economical than replacing the complete axle cylinder assembly.

Compatibility

This kit is specified by Toyota for the following forklift series:

• 3FD / 3FG series: 3FD50, 3FD60, 3FG50 and 3FG60, including the 40-3FD50 variant
• 3SD series: 3SD20, 3SD23 and 3SD25

The 04431-30091-71 for 3FD50 also covers the sister models listed above, so a single part number serves several trucks in the same capacity class. Before ordering, confirm the model code on the truck data plate, or send us your model and serial number, and our parts specialists will verify fitment for you.

Quality and Reliability

Because the 04431-30091-71 is a genuine Toyota part, it is produced to the same specifications as the components originally fitted to your forklift. In a brake cylinder, correct seal material, precise dimensions and consistent hardness are critical; even small deviations can cause leaks, sticking or uneven braking. Sticking with the correct Toyota part number helps protect braking performance, supports longer service intervals and reduces the risk of repeat repairs on the same axle.

Installation and Maintenance Tips

• Check the truck model and serial number against the data plate before starting work.
• Follow the Toyota service manual for your model when dismantling and reassembling the rear axle cylinder.
• Inspect the cylinder bore for scoring, corrosion or pitting; a badly damaged bore may need machining or full cylinder replacement rather than a kit overhaul.
• Replace the internal components as a complete set and never mix old and new seals.
• Use clean, specified brake fluid and bleed the brake circuit thoroughly after reassembly.
• If one rear axle cylinder is worn, overhauling the cylinder on the opposite side at the same time helps keep braking force balanced.
