What's wrong?
The jack cylinder assembly on the 2022 Terex Optima Tc, Xt Pro, and C4000 outrigger vehicles raises, lowers, and holds the outrigger in position while the equipment is set up. Inside that assembly, the outrigger cylinder uses hydraulic pressure to support the load. A lock valve cartridge seal helps trap that pressure so the cylinder stays where the operator places it.
On the affected units, the outrigger cylinder was machined incorrectly. That machining issue changes how the lock valve cartridge seals sit and seal inside the cylinder. When those seals fail to hold pressure, hydraulic fluid can bypass the valve, and the outrigger can drift instead of staying fixed.
The warning sign is outrigger movement during the operator's daily pre-shift check of outrigger and boom functions. If an outrigger settles, creeps, or moves after it is set, that is the condition this recall is meant to catch.
Who's affected?
The common item is the jack cylinder assembly, part number 631148, across all three models.

What's the safety risk?
A drifting cylinder can let the machine tip, increasing the risk of injury. Operators should complete the daily pre-shift check of outrigger and boom functions before use. If an outrigger drifts during the check, keep the machine out of service and arrange the recall repair. Repair is free at any franchised Terex dealer.

- Reference recall number 22V888 and Terex recall SN714 when you call.

What happens at the repair
