Jcb 802 Super

At the 500-hour interval, collect oil samples from the engine, hydraulic tank, and final drives to establish a baseline. Monitor hydraulic oil temperature via the sight gauge and check the return filter magnet for metallic debris. Inspect the coolant expansion tank for proper level and contamination. Use JCB-spec long-life coolant at the 1000-hour service. Track undercarriage wear against JCB limits to predict track and sprocket replacement needs before failure.

Address hydraulic hose chafing at the kingpost and boom pivot points, common failure sites on the 802 Super. Replace worn track rollers and idlers when sag exceeds limits. Inspect the slew ring bolts for torque loss and replace if stretched. Check the fuel injection pump solenoid electrical contact for corrosion. Replace the air filter element if the restriction indicator shows clogging. Verify the overload sensor calibration for safe lifting operations.

At 2000 hours, measure swing ring radial and axial play using a dial indicator. Inspect structural welds on the boom, arm, and chassis for cracks or unauthorized repairs. Check the turbocharger shaft play and charge cooler boot integrity. Inspect brake disc wear and immersed brake condition. Replace the hydraulic oil cooler if internal contamination is detected. Evaluate the engine piston and connecting rod condition if oil consumption increases significantly.

Before storage, retract bucket and dipper rams, lower the boom, and spray exposed ram rods with Waxoyl. Slacken rubber tracks to remove spring tension. Fill the fuel tank to maximum to prevent condensation. For cold climates, use appropriate grade engine oil and check the coolant freeze point. In high-temperature environments, monitor the hydraulic oil cooler for blockage. Ensure the cab HVAC system is serviced to maintain operator comfort and defrosting capability.
