140001- Komatsu Lift Cylinder 37A-7LT-5030UE for FB15RL-14
Overview
The 140001- 37A-7LT-5030UE LIFT CYLINDER ASS’Y,(FOR 4.3M MAST) |$ is a replacement lift cylinder assembly for Komatsu electric counterbalance forklifts equipped with a 4.3-meter mast. It converts hydraulic pressure into the linear force that raises and holds the fork carriage under load. Common signs of a worn cylinder include drifting forks, uneven lifting and oil leakage around the barrel or seals. Referenced to OEM number 37A-7LT-5030UE, this 140001- assembly matches the stroke, mounting points and performance of the original 4.3M mast unit.
Compatibility
This lift cylinder assembly fits the Komatsu RL-14 and RW-14 series of electric counterbalance forklifts:
- FB10/13RL-14
- FB10/13RW-14
- FB15RL-14
- FB15RW-14
- FB18RL-14
The same 37A-7LT-5030UE specification serves the family from the FB10/13 to the FB15 and FB18 capacity classes whenever the truck is fitted with the 4.3M mast. Whether you are sourcing a 140001- for FB10/13RL-14 trucks or a replacement cylinder for an FB15RW-14, the fitment is identical across these capacities. Always confirm your mast height and truck serial number before ordering, since Komatsu used different cylinder variants for other mast options.
Quality and Reliability
This 37A-7LT-5030UE lift cylinder assembly is produced to align with the Komatsu original specification for the RL-14 and RW-14 series. A precision-machined barrel and rod, combined with a sealing set matched to the lift circuit’s operating pressures, support consistent lift speeds and stable load holding. Because the assembly is dedicated to the 4.3-meter mast, no modification of the mounting points should be required during fitting. A correct-fit cylinder also protects chains, mast channels and hoses from the uneven loads caused by a sticking or leaking unit.
Installation and Maintenance Tips
- Relieve hydraulic pressure and lower the forks fully before disconnecting any hose.
- Support the mast and carriage securely; never rely on hydraulic pressure to hold components during service.
- Before fitting the new 140001- assembly, compare it with the old cylinder: check mounting lugs, overall length and hose ports.
- Fill and bleed the system with clean hydraulic fluid to the Komatsu-specified grade, then cycle the mast slowly and inspect every joint for leaks.
- During routine service, keep the cylinder rod clean and free of scoring, and attend to any seal weeping promptly to protect the pump and valves.
