FAQs

Q: Which JCB machines use this 25/221236 counterbalance valve?

A: It is fitted on JCB Loadall telehandler models, including construction and agricultural versions: 540-170, 550-170 (including Tier 2 emission variant), and 5508.

Q: What symptoms indicate the counterbalance valve needs to be replaced?

A: Common warning signs:

1. Boom drift: When the boom is lifted or extended, it slowly sinks or retracts under load even without operating the control lever.
2. Jerky movement: Shaking, stuttering or abnormal noise when lifting or lowering loads, caused by unstable oil flow control. These faults usually happen from spring fatigue, spool wear with internal leakage, or debris jamming the valve spool.

Q: What is the main purpose of a counterbalance valve on telehandlers?

A: It acts as a hydraulic safety valve. It holds pressure in the cylinder to stop the boom from falling under heavy load, and smooths oil flow during boom extension and retraction for safer load handling.

Q: What checks should be completed before ordering this replacement valve?

A: Confirm your telehandler model and the existing valve part number. Check hydraulic oil cleanliness, as contaminated oil can damage the new valve cartridge quickly after installation.
