Komatsu 3EC-02-42520 HOSE for FD35/40-8 Forklift Trucks

Overview

The 3EC-02-42520 HOSE is a Komatsu-branded replacement hose supplied for a wide range of Komatsu pneumatic tire diesel forklifts. Hoses play a critical role in keeping fluid lines sealed and pressurized, and a worn or cracked hose can quickly lead to leaks, pressure loss, and unplanned downtime. This 3EC-02-42520 HOSE is produced to the original Komatsu part specification, so it is intended to fit and perform exactly where the factory part was installed. If you are sourcing a dependable replacement for an aging or damaged line, this Komatsu part number is the correct reference to order.

Compatibility

The 3EC-02-42520 for FD35/40-8 applications also covers a broader family of Komatsu forklifts across the 8-series and 10-series ranges, including:

• Komatsu FD35/40-8 series, including the FD35Z/40Z-8 variants
• Komatsu FD45-8
• Komatsu FD50/60-8 series, including the FD50/60-8-EC
• Komatsu FD50A-8
• Komatsu FD60-10 series, including the FD60-10-EC and FD60-10-US

Because hose fitment can vary with truck configuration and serial number, we recommend confirming your model and serial number with our team before ordering. No alternative OEM cross-reference numbers have been published for this part, so ordering by the Komatsu part number 3EC-02-42520 is the most reliable method.

Quality and Reliability

As a Komatsu component, the 3EC-02-42520 HOSE is manufactured to Komatsu’s engineering standards for material quality, pressure handling, and durability. Correct material construction and precise end fittings help ensure a secure, leak-free connection and a service life consistent with the original part. Choosing the specified Komatsu part number rather than an unverified substitute reduces the risk of fitment problems and repeat repairs on your FD50/60-8, FD45-8, or other compatible trucks.

Installation and Maintenance Tips

• Relieve system pressure and allow the machine to cool before removing the old hose.
• Place a container under the connections to catch residual fluid.
• Inspect adjacent hoses, clamps, and fittings for wear while the line is open.
• Route the new hose exactly as the original to avoid rubbing or heat exposure.
• Tighten fittings to specification and check for leaks after refilling and testing.
• Schedule regular visual inspections for abrasion, bulging, or cracking, and replace hoses at the first sign of deterioration.

We recommend that installation be carried out by a qualified technician familiar with Komatsu forklifts.
