Doosan D510852 Side Shift Cylinder Kit for BR Reach Trucks

Overview

The D510852 Side SHift Cylinder Kit is the Doosan replacement kit for the side shift cylinder fitted to BR-series electric reach trucks. The side shift cylinder is the hydraulic actuator that moves the fork carriage left and right, letting operators line forks up with pallets and racking without repositioning the whole truck. When this cylinder wears out, you typically notice slow or drifting side shift, visible hydraulic leaks, or forks that no longer sit square. This kit is intended to restore smooth, precise lateral fork positioning and dependable hydraulic performance.

Compatibility

The D510852 kit is specified for the following Doosan forklift series:

• BR13/15/18 series — J5 (SB1116), S5 (SB1115) and S7 (SB1125) variants
• BR14/16JW5 series — SB1117
• BR20/25S5 series

Whether you need D510852 for BR13/15/18J5 reach trucks or a matching kit for the BR20/25S5, confirm the model and application code (such as SB1115 or SB1116) on the truck’s data plate before ordering. Unsure which kit your truck takes? Send us your model and serial number and we will help you verify the correct part.

Quality and Reliability

As a Doosan-branded component ordered under the exact part number D510852, this side shift cylinder kit is designed to match the fit and function of the original cylinder on these trucks. Fitment precision matters on reach trucks: a poorly matched cylinder can cause uneven side shifting, premature seal wear and hydraulic contamination. Ordering by the exact Doosan part number removes the guesswork and helps ensure the kit bolts into place and connects to your existing hydraulic lines as intended. For this application, D510852 is the definitive ordering reference.

Installation and Maintenance Tips

• Fully lower the forks, park on level ground and de-energize the hydraulic system before starting work.
• Follow the Doosan service manual for your specific model when removing the carriage and disconnecting hydraulic lines.
• Cap open hoses and ports during the swap to keep dirt out of the hydraulic circuit.
• Inspect hoses, fittings and mounting points while the old cylinder is out; replace anything showing wear.
• Use the seals and hardware supplied in the kit and torque fittings to specification.
• After installation, cycle the side shift slowly, check for leaks and verify smooth travel in both directions before returning the truck to service.

Regular cleaning of the cylinder rod and routine leak checks will help the new cylinder deliver a long service life.
