Jcb 801.6N
Maintenance schedule, common problems & OEM parts breakdown
The JCB 801.6N is a mini excavator manufactured from 1993 to 1999. It weighs 1.61 tons (3,550 lb) and features a transport width of 1.21 meters (4 ft). The machine is part of the 801 series lineage, succeeding the 801 and preceding the 801.6N variants in the mini excavator range. It is powered by a JCB 403C-11 engine producing 19 hp (14 kW). Configurations include standard and CTS (Compact Tail Swing) models with varying cab and canopy options.
The 801.6N represents a generation of JCB mini excavators designed for utility work and confined spaces. It matters in the used and parts market due to its simple mechanical design and lack of complex emissions systems compared to later models. The machine's popularity stems from its durability and the availability of aftermarket parts for its engine and hydraulic systems. Owners often seek replacement components for the 403C-11 engine and hydraulic pumps, which are known to require maintenance after extended service life.

Servicing the 801.6N beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor engine oil and hydraulic fluid levels daily. Use JCB-spec 15W-40 diesel oil for the engine. Check the hydraulic oil sight gauge regularly. Inspect the fuel water separator daily and drain if water is present. Analyze oil samples every 500 hours to detect early wear in the engine and hydraulic systems. Clean the radiator and oil cooler screens to prevent overheating. Inspect the air filter restriction indicator and replace the primary and secondary fuel filters at 250-hour intervals.
Corrective & Common Repairs
Address hydraulic pump leaks promptly, as they are common on older 801.6N units. Replace worn track shoes and rollers to maintain undercarriage life. Inspect the slew ring bolts and torque to specification. Check the turbocharger boot for cracks and shaft play. Replace hydraulic hoses showing chafing or weeping. Inspect the engine oil cooler for blockages. Ensure the alternator and fan belts are tensioned correctly to prevent premature failure.
Overhaul & Rebuild Points
At 2000 hours, replace the hydraulic oil and clean the hydraulic tank. Inspect the structural chassis for cracks or unauthorized welding. Measure slew ring radial and axial play. Check the brake disc wear and condition. Inspect the engine cylinder liners and piston rings for wear. Replace the hydraulic return filter and inspect the magnet for metallic debris. Check the final drive oil levels and condition.
Seasonal & Environment Servicing
In cold weather, check the coolant concentration to prevent freezing. Inspect the engine oil viscosity and change if necessary. In hot weather, clean the radiator and oil cooler screens more frequently. Check the cabin HVAC system for proper operation. Inspect the track tension and adjust if necessary. Grease all pivot points regularly to prevent corrosion. Check the battery electrolyte level and clean terminals.

Frequently asked questions
What engine does the JCB 801.6N use?
The JCB 801.6N uses a JCB 403C-11 engine producing 19 hp (14 kW).
What is the operating weight of the JCB 801.6N?
The operating weight is 1.61 tons (3,550 lb).
What model replaced the JCB 801.6N?
The JCB 801.6N was succeeded by later variants in the 801 series, including the 801.6N with updated configurations and the 8020 CTS.
What 801.6N owners discuss
What engine powers the JCB 801.6N, and what are the common starting or performance quirks associated with this series?
The JCB 801.6N is powered by a Perkins 3-cylinder injection diesel engine. Owners report that these engines often struggle with starting, particularly when cold, producing significant black smoke and requiring multiple cranking attempts to fire. Once running, the engine is generally reliable, but poor maintenance can lead to stubborn restart issues. The fuel filler design is noted as inconvenient for filling with cans, and the dipstick is exceptionally long, complicating oil level checks.
What are the known hydraulic system behaviors and failure modes for the JCB 801 series?
The hydraulic system is prone to leaks and pump failures, with pumps often requiring replacement after approximately 3,000 hours. A common issue involves the spool valve block; internal swarf or debris can jam valves, causing multiple functions (such as dipper, auxiliary, and track) to fail simultaneously. Additionally, seal packs on hydraulic rams can separate from the rod end due to a lack of retention pins, a design flaw noted by mechanics. O-rings in the valve block may also harden over time, losing elasticity and causing internal leakage when the block is disassembled or heated.
What undercarriage wear patterns and maintenance requirements are typical for this machine?
The JCB 801.6N features a track width of 230 mm. Undercarriage components, including sprockets and idlers, require regular inspection and realignment to prevent premature wear. The machine has numerous grease points that must be lubricated regularly to maintain performance. Tracks must be kept properly tensioned to ensure optimal traction and prevent damage. The undercarriage is subject to rigorous use, and worn tracks can significantly reduce machine efficiency.
What electrical and sensor issues are commonly discussed by owners?
Electrical problems often stem from corroded wiring harnesses, low voltage batteries, or faulty connections. In some JCB models, intermittent operation is caused by microswitches on the forward/reverse lever failing to activate hydraulic solenoids. For the 801 series, wiring issues can lead to intermittent power loss or malfunctioning controls. Owners are advised to regularly check battery voltage and inspect wiring for fraying or loose connections, ensuring all electrical components are turned off when the machine is not in use to preserve battery life.
What specific hydraulic valve issues are reported for the JCB 801 series?
Owners report that clevis pins attaching the valve/spool assemblies can wear out due to age, causing slack in the slewing and dozer blade controls. This wear may require drilling out holes to accept larger pins. Additionally, when servicing the spool slices, mechanics note that the long bolts holding the block together can be over-tightened or torqued unevenly, causing spools to jam. Proper reassembly requires ensuring all O-rings are intact and that hoses are correctly routed to the appropriate spools.
What fluids and capacities are specified for the JCB 801.6N?
The engine holds 3.5 liters of coolant. The hydraulic system requires 17 liters of ISO 46 hydraulic oil. The canopy holds 4.5 liters of coolant, and the cab fuel system holds 5.0 liters. The engine oil capacity is not explicitly stated in the provided sources, but standard 10W-40 or 15W-40 engine oils are commonly used in similar JCB applications. The machine has a 30-liter fuel tank capacity.
What should be checked when buying a used JCB 801.6N?
Inspect the hydraulic pump for signs of wear, as failures are common around 3,000 hours. Check the spool valve block for internal debris or hardened O-rings that could cause function loss. Verify the condition of the clevis pins on the valve/spool assemblies for wear. Examine the engine for excessive black smoke during startup, indicating potential injector or compression issues. Check the undercarriage for track tension and sprocket/idler wear. Ensure the wiring harness is intact and free of corrosion. Have your dealer verify the engine serial number and hydraulic pump condition.
