3185021280 Lift Cylinder Assy 1st | Mitsubishi FB20 Forklift

Overview

The 3185021280 CYLINDER ASS’Y LIFT(1ST) is the first-stage lift cylinder assembly for Mitsubishi electric counterbalance forklifts. Mounted inside the mast, this hydraulic cylinder performs the initial stage of every lifting cycle, raising the inner mast and carriage before the second stage takes over. With heavy daily use, worn seals, contaminated oil and internal wear can lead to fork drift, slow or uneven lifting, and hydraulic oil loss. Replacing a tired cylinder with the 3185021280 assembly restores smooth mast operation, protects the rest of the hydraulic circuit, and keeps loads precisely under control at height.

Compatibility

The 3185021280 for FB20(H)CA and its sister trucks fits the Mitsubishi FB series electric four-wheel forklifts in the 2.0-3.0 tonne capacity range, across two model generations:

• FB(H)CA series – FB20/25/28/30(H)CA electric counterbalance trucks (2.0 t, 2.5 t, 2.8 t and 3.0 t)
• CA1(J) series – FB20/25(H)CA1(J) and FB28/30CA1(J), the later-generation versions of the same chassis

To confirm fitment on your specific truck, check the number stamped on your current cylinder, or send us your model and serial number and our team will verify it before you order.

Quality and Reliability

Each 3185021280 lift cylinder assembly is manufactured to match Mitsubishi’s OEM specification for bore, stroke, mounting dimensions and working pressure, so it installs into the mast without modification. Hard-chromed rod surfaces, honed cylinder bores and pressure-rated seal packages are used to resist scoring, corrosion and internal bypass in demanding warehouse and yard duty. Because this component controls the first stage of the lift, matching the original cylinder geometry exactly is critical for correct mast sequencing – a specification-matched replacement ensures the carriage and chains travel as the truck was designed to.

Installation and Maintenance Tips

• Depressurize the hydraulic system and fully lower the mast before starting any work.
• Support the carriage and mast components with rated stands – never rely on hydraulic pressure to hold a load.
• Label, drain and cap hydraulic lines during removal to keep dirt out of the circuit.
• Inspect hoses, fittings and the second-stage cylinder while the assembly is exposed.
• After fitting the new cylinder, refill with clean hydraulic fluid, bleed air from the circuit, and cycle the mast slowly while checking for leaks.
• Re-check mounting fasteners after the first hours of operation and examine the rod surface during every scheduled service.
