Jungheinrich 51032840 Cylinder, Lift LH for DFG 660 Series

Overview

The 51032840 Cylinder, Lift LH is the left-hand lift cylinder for Jungheinrich DFG series diesel counterbalance forklifts. Installed in the mast assembly, this hydraulic cylinder converts hydraulic pressure into the lifting force that raises the forks and their load. Because the lift cylinder sits at the heart of safe, controlled load handling, a worn, scored or leaking cylinder should be replaced without delay. The 51032840 is produced to match the original Jungheinrich specification in dimensions, mounting points and hydraulic performance, so it is intended to fit as a direct replacement on compatible trucks — no rework, no improvisation.

Compatibility

The 51032840 for DFG trucks covers the Jungheinrich diesel forklift families listed for this part:

• DFG 660 series — standard DFG 660 trucks
• DFG 660-4 series — the later 660-4 generation of the same family
• DFG 660/670 series — the related 660 and 670 model range

Because mast variants and cylinder configurations can differ within a model family, always check the part number 51032840 against the data plate on your truck or your Jungheinrich parts documentation before ordering. If you are unsure, our team can help you confirm fitment using your model and serial details.

Quality and Reliability

A lift cylinder works under constant high pressure, so material quality matters. This replacement cylinder is manufactured with a precision-machined barrel, a hard-chrome-plated piston rod for smooth travel and wear resistance, and durable seals designed to prevent internal and external leakage. Corrosion-resistant finishes on exposed surfaces help the cylinder cope with dusty warehouses, damp yards and outdoor loading — the everyday conditions Jungheinrich DFG trucks are built for.

Installation and Maintenance Tips

• Fully lower the forks, shut the engine down and relieve hydraulic pressure before starting work.
• Secure the mast and lift chains mechanically; never rely on hydraulics to hold a raised mast.
• Disconnect the hydraulic lines and cap them immediately to keep dirt out of the circuit.
• Inspect hoses, seals and mounting bushes while the cylinder is out, and replace worn items at the same time.
• Torque all mounting hardware to the manufacturer’s specification and bleed air from the hydraulic system afterwards.
• Check regularly for leaks, scored rods or uneven lifting — early signs that service is due.

Installation should be carried out by a trained forklift technician following the manufacturer’s service manual.
