Mitsubishi 0400512045 Hose ass’y, H.P | RB Series Forklift

Overview

The 0400512045 Hose ass’y, H.P is a Mitsubishi high-pressure hose assembly for the hydraulic circuit of the compact RB series trucks. High-pressure hose is one of the most safety-critical wear items on any forklift: it carries pressurized hydraulic fluid through the lift circuit, and a worn or damaged line can cause pressure loss, sluggish lifting or sudden failure. This replacement assembly is intended to restore original hydraulic performance on trucks such as the RBS10N-CB1 and RBS12N-CB1, making it a sensible part to stock for service departments and fleet operators.

Compatibility

If you are searching for the 0400512045 for RBS10N-CB1, this listing covers that truck along with the rest of the closely related RB series family. The hose fits the RBS10 and RBS12 models across their N and non-N variants and both the CB and CB1 build groups — for example the RBS12-CB1 and RBS12CB trucks — so a single part number serves the whole RBS10/RBS12 range in this series. Manufacturers occasionally revise hose routing or end fittings during a production run, so we recommend confirming your truck’s model and serial number before ordering. Send us the details and our team will verify the match for you.

Quality and Reliability

Hydraulic hose is not a component to compromise on. This high-pressure assembly is designed to match the fit and function of the original Mitsubishi component, with end fittings intended to connect to the truck’s standard hydraulic connections. Correctly specified H.P hose maintains stable system pressure, resists weeping at the joints and helps protect the pump and lift circuit from contamination that can enter through failed lines. As with any hydraulic part, it should be inspected at every service interval and replaced at the first sign of wear.

Installation and Maintenance Tips

• Fully lower the forks and relieve system pressure before disconnecting any hydraulic line.
• Place a drain tray under the work area and cap open ports to keep dirt out of the circuit.
• Route the new hose exactly as the original, clear of sharp edges, hot surfaces and pinch points, and secure it with the original clips.
• Tighten the fittings to specification, then run the truck and recheck for leaks after the first operating cycles.
• Inspect regularly for abrasion, bulging, cracked outer covers or damp fittings, and replace the hose rather than attempting a repair.
