Komatsu 3EB-36-51180 Master Cylinder FB09-FB20 Forklifts

Overview

The 3EB-36-51180 CYLINDER ASS’Y,MASTER is a replacement brake master cylinder designed for Komatsu electric counterbalance forklifts. As the core component of the hydraulic brake circuit, the master cylinder converts pedal force into hydraulic pressure and sends it through the brake lines so the truck can slow down and stop safely. When this part wears, operators often notice a soft or spongy pedal, longer stopping distances or brake fluid leaks — signs that should not be ignored on material handling equipment. This Komatsu 3EB-36-51180 master cylinder is built to match the fit, function and performance of the original component, making it a straightforward replacement on compatible FB-series trucks.

Quality and Reliability

Brake components are safety-critical, so the 3EB-36-51180 is manufactured with close attention to bore dimensions, surface finish and sealing performance. Its construction is specified to handle the hydraulic demands of daily warehouse and industrial operation, delivering consistent pedal feel and dependable stopping power over the service life of the part. Like all Komatsu replacement parts we supply, the 3EB-36-51180 is matched to the original part number so it bolts into place without modification.

Installation and Maintenance Tips

To get the best results from your new master cylinder:

• Park on level ground, lower the forks, switch off the power and apply the parking brake before starting work.
• Disconnect the battery so the truck cannot be moved accidentally during the repair.
• Note the brake line routing before removing the old cylinder, and cap open lines to keep dirt and moisture out.
• Fit the new 3EB-36-51180, reconnect the brake lines to their original positions and refill with the brake fluid specified by Komatsu.
• Bleed the brake system thoroughly after installation to remove trapped air and restore a firm pedal.
• Re-check the fluid level and inspect for leaks after the first few operating hours, then follow the inspection intervals in your Komatsu service manual.
