000670003 Valve Control Screw Plug | Mitsubishi FB Forklift

Overview

The Mitsubishi 000670003 PLUG,SCREW 4V_EQUAL MOVEMENT_VALVE CONTROL is a precision screw plug specified for the valve control assembly of Mitsubishi FB-CB electric counterbalance forklifts. Although it is a small component, it performs a vital sealing and fastening function inside the equal movement valve control unit. A worn, corroded, or over-torqued plug can allow oil seepage or dirt ingress, which may lead to sluggish lift or tilt response and unplanned downtime. Replacing it promptly with the correct part number restores the assembly to its intended working condition.

Compatibility

The 000670003 for FB10CB and its sibling trucks covers the compact Mitsubishi FB-CB electric range. Grouped by series, the fitment list includes:

• FB10CB–FB25CB series – compact electric counterbalance models such as the FB10CB, FB15CB, FB18CB, FB20CB, and FB25CB
• FB20LCB–FB25LCB series – the corresponding LCB variants, including the FB20LCB and FB25LCB

Because trim and chassis revisions can vary between production years, always confirm 000670003 against the parts diagram in your truck’s service manual, or contact our team with your serial number before ordering.

Quality and Reliability

This screw plug is supplied as a Mitsubishi-specification spare part, produced to the dimensions, thread form, and material grade defined for the original valve control assembly. That matters for a sealing component: correct thread geometry ensures a tight, even seat, while suitable material resists corrosion from hydraulic oil and workshop conditions. Every order is checked against the 000670003 part number so you get the plug intended for your FB series truck, not an approximate substitute.

Installation and Maintenance Tips

• Depressurize the hydraulic circuit and lower the forks completely before opening the valve control area.
• Clean the housing surface around the plug so debris cannot fall into the assembly during removal.
• Inspect the plug seat and housing threads; if the threads show damage, address that before fitting a new plug.
• Check whether your parts manual specifies a separate seal or washer with 000670003 and renew it at the same time.
• Tighten to the torque value given in the Mitsubishi service manual and re-check for leaks after the first operating hours.
