A235011 Filter Suction for Doosan B40/45/50X5 Forklifts

Overview

The A235011 Filter Suction is a suction-side hydraulic filter supplied for a wide range of Doosan forklifts. Positioned on the intake side of the hydraulic system, this filter captures dirt, metal particles and other contaminants before they can reach the hydraulic pump, helping to protect one of the most expensive components in the machine. If a suction filter becomes clogged or damaged, oil flow is restricted and the pump is forced to work harder, which can lead to slow lift performance, noise and premature wear. Replacing the A235011 Filter Suction at recommended service intervals is a simple, low-cost way to keep your Doosan forklift running smoothly.

Compatibility

The A235011 for B40/45/50X5 (SB1085) covers Doosan’s electric counterbalance range, while the same part also serves several diesel families:

• D35/40/45S-2 series diesel forklifts
• D40/45/50SC-2 series compact diesel forklifts
• D110/130S5 series (SB1105, Tier 2) heavy diesel forklifts
• D160S5 (SB1106, Tier 2) heavy diesel forklifts

This suction filter is also listed under the related reference number A231526. Because Doosan part numbers can vary between engine tiers and market versions, we recommend confirming your model and serial number before ordering.

Quality and Reliability

This Doosan A235011 suction filter is a direct replacement produced against the original manufacturer’s specification, so it fits the factory filter housing without modification. Correct filtration performance is essential on these models: a properly functioning suction filter maintains clean oil flow to the pump and helps prevent internal damage caused by contamination. Each unit is checked against the A235011 part specification before dispatch, so you receive the correct filter for your machine.

Installation and Maintenance Tips

• Always relieve system pressure and lower the mast fully before starting work.
• Replace the suction filter whenever the hydraulic oil is changed, or sooner if oil analysis shows high contamination.
• Inspect the filter housing, seals and O-rings for damage, and fit new seals where required.
• Note the orientation of the filter before removal to ensure correct reinstallation.
• Dispose of used oil and filters in line with local environmental regulations.

Always follow the service intervals in your Doosan manual for the specific model you operate.
