Jcb 722(TIER 3)

Baseline fluid analysis is critical for the JCB 722’s Cummins engine and hydraulic systems. Take samples at the 500-hour interval from the engine crankcase, hydraulic tank, and front/rear axles. Compare subsequent results against this baseline to detect early bearing wear or contamination. Monitor the hydraulic return filter magnet for metallic debris during every 500-hour service. Use JCB Super Universal Agricultural fluid or equivalent for multipurpose applications in transmissions and hydraulics to prevent silicate separation in the cooling system.

Address turbocharger boot leaks and wastegate function issues common in the Tier 3 Cummins engine during the 1000-hour audit. Inspect the four-bar parallel link front suspension gas strut accumulator for leaks that compromise self-levelling. Check the articulated pivot point for excessive play and lubricate the slew ring bearings regularly. Replace worn tires based on measured wear limits to maintain ground clearance and stability. Verify the condition of the primary and secondary fuel filters to protect common-rail injectors.

The 2000-hour deep service requires measuring swing ring play on tracked variants and inspecting the slew gearbox oil for contamination. Check the structural integrity of the boom, arm, and chassis side frames for unauthorized welding or cracking. Service the immersed brake system on wheeled configurations, replacing discs as needed. Inspect the engine injectors for spray pattern degradation and replace if necessary. Ensure the hydraulic tank is thoroughly cleaned during the oil change to prevent pump cavitation and component failure.

In cold climates, use JCB 15W-40 Multigrade oil rated for -15°C to 30°C or lower temperatures with appropriate additives. Check the battery electrolyte levels in non-sealed units and clean terminals to ensure reliable starting. In dusty environments, inspect the air filter restriction indicator frequently and clean the radiator and oil cooler cores to prevent overheating. Store the machine under cover to protect the cab HVAC system and electrical components from corrosion. Verify the condition of all hydraulic hose fittings for weep at the kingpost and boom pivots.
