Known problems

AdBlue and DPF

These Tier 4 Final engines carry an AdBlue tank. Keep it topped up with clean AdBlue and keep the filler cap shut; dirty or wrong fluid can damage the dosing system.

Brake fluid type

Loadall brakes run on JCB hydraulic fluid. DOT brake fluid damages the seals and brake pack: check your handbook for the right one.

Boom wear pads and main pivot

Rock the extension for side play. Unshimmed pads can crack the area around the main pivot pin.

Accumulators

Accumulators hold pressure with the engine off. JCB says only a dealer should discharge them.

Repair guides

Fork carriage removal and refitting (pivot pins and tipping link) (Hard, 2–4 hours): Worn or seized carriage pivot pins, play at the boom head, cracked carriage, or the carriage has to come off for a repair or a different hitch.
Before any hydraulic or boom job: maintenance position, pressure release and accumulators (Easy, 15–30 minutes before the main job): You need to change a hose, ram seal or filter, work near the boom, or check the hydraulic oil level, and want to do it without trapped pressure or a falling boom.
Brake fluid level falling and brake checks (Tier 4 Final Agri Loadalls) (Specialist, 15 minutes to check; brake pack work is a dealer job): Brake reservoir level dropping, soft or long pedal, machine pulling, handbrake weak on a slope.

The full step-by-step guides are in Farmyard Workshop once you add your telehandler.
