Komatsu 37R-503-1180 HOSE for FD135-7 FD135-8 Forklift

Overview

The Komatsu 37R-503-1180 HOSE is a direct-fit replacement hose designed for Komatsu’s heavy-capacity pneumatic tire forklift families, including the FD135, FD150E and FD160E model lines. Hoses on these machines operate under constant heat, vibration and pressure cycling, so they naturally wear over time and should be replaced at the first sign of cracking, swelling or leakage. The 37R-503-1180 for FD135-7 and its sibling models restores proper fluid routing and helps you return your forklift to service quickly and safely.

Compatibility

This hose is engineered to fit the following Komatsu forklift series:

• FD135 series – FD135-7, FD135-7-OP and FD135-8 configurations
• FD150E series – FD150E-7, FD150E-7-OP and FD150E-8 configurations
• FD160E series – FD160E-7 and FD160E-7-OP configurations

Because Komatsu applies the same 37R-503-1180 HOSE across these closely related 7-series and 8-series machines, one part can serve multiple units in your fleet. Always confirm fitment by matching the part number printed on your original hose or referenced in your parts manual before ordering.

Quality and Reliability

As the Komatsu-referenced part number for these applications, the 37R-503-1180 HOSE is intended to match the factory dimensions, fitting types and routing of the component it replaces. A correct-fit hose minimizes stress on end fittings, reduces the risk of kinks or chafing, and supports consistent performance in demanding material handling environments. Choosing the right Komatsu part number the first time helps prevent repeat repairs and unplanned downtime.

Installation and Maintenance Tips

• Relieve system pressure and allow the machine to cool before disconnecting the old hose.
• Capture and drain residual fluid, and keep contaminants out of open lines and fittings.
• Compare the old hose with the new 37R-503-1180 HOSE to confirm length, end fittings and bend orientation.
• Route the new hose exactly as the original to avoid contact with hot or abrasive surfaces.
• Tighten fittings to specification and inspect for leaks after the first operating cycles.
• Schedule regular visual inspections of all hoses as part of your planned maintenance routine.
