Servicing the 801 beyond the schedule

Predictive Maintenance & Fluid Analysis

Baseline fluid analysis at 500 hours is critical for the JCB 801’s Perkins 103-09 engine and hydraulic system. Sample engine oil, hydraulic fluid, and track gearbox oil to detect early wear. Use JCB Special Hydraulic Fluid (HP32 for cold climates, HP46 for hot climates) to maintain viscosity. Monitor the hydraulic return filter magnet for metallic debris, indicating pump or valve wear. Track gearbox oil must be JCB SAE 30 Engine Oil (MIL-L-2105D). Deviations from baseline samples signal developing issues in the swing gearbox or track rollers before failure occurs.

Corrective & Common Repairs

Common JCB 801 repairs include replacing the hydraulic filter, which is accessed via a spring-loaded cover under the seat. Ensure the filter is oriented correctly to avoid damaging the spring. Inspect the fuel separator bowl for dirt, which can bypass the filter and damage injectors. Check cylinder rods for scoring and replace piston seals if external leaks are present. Inspect the slew ring bolts for proper torque, as loose bolts can lead to structural damage. Replace worn track rollers and idlers to maintain proper track tension and prevent derailment.

Overhaul & Rebuild Points

At 2000 hours, inspect the boom, arm, and chassis for cracking or unauthorized welding. Measure swing ring radial and axial play using dial indicators; excessive play indicates worn bearings. Inspect brake disc wear and immersed brake condition. Check injector spray patterns via diagnostic tool and replace as required. Service the cab HVAC system, including A/C pressure checks and cabin filter replacement. Drain the hydraulic tank, clean the interior, and refill with JCB Special Hydraulic Fluid. Inspect the turbocharger shaft play, boot condition, and wastegate function.

Seasonal & Environment Servicing

In cold climates, use JCB HP32 hydraulic fluid to maintain viscosity. In hot climates, use JCB HP46. Check the coolant level in the expansion tank regularly, as silicate separation can cause brown sludge. Drain water from the fuel separator bowl to prevent injector damage. Inspect the air filter restriction indicator and clean or replace the pre-cleaner. Grease all pivot points more frequently in dusty environments. Check track tension and roller condition to prevent excessive wear in abrasive conditions. Ensure the cab HVAC system is serviced to maintain operator comfort and visibility.

Frequently asked questions

What engine does the JCB 801 use?

The JCB 801 uses a Perkins 103-09 engine, providing 16 HP of reliable, low-fuel-consumption performance.

What is the operating weight of the JCB 801?

The JCB 801 has an operating weight of 1.43 tons (1,430 kg).

What model replaced the JCB 801?

The JCB 801 was replaced by the JCB 801.4, which was manufactured from 1993 to 1999.

What 801 owners discuss

What is the primary cause of violent rocking and cab movement in early 1990s JCB 801 models, and how is it verified?
The slew ring bearing is worn out. Verification requires pressing the bucket down to lift the tracks, then lifting the bucket off the ground while observing the bearing from the side for play. Greasing the slew ring and pinion can reduce jerky movement but does not fix worn slack. Sheared slew ring bolts are less likely to cause significant pitch unless multiple bolts have failed. Have your dealer verify the slew ring condition before replacement.
What are the typical hydraulic spool and valve issues reported for the JCB 801 series?
Clevis pins attaching the valve/spool assemblies to the control learms wear out over time, creating slack in the slewing and dozer blade controls. Drilling out arm holes to accept larger clevis pins is a common field fix. For later models like the 8018, metal swarf can lodge in the track slice of the valve block, holding it open and causing multiple functions (e.g., LH track, dipper, aux) to fail simultaneously. Have your dealer verify valve block integrity if multiple functions fail.
What undercarriage and wear patterns are typical for the JCB 801?
The JCB 801 (1988–1993) has a track width of 230 mm. The 801.4 (1993–1999) retains the 230 mm track width but increases in weight from 1.43 tons to 1.48 tons. The 801.5 Powerplus (1995–1999) weighs 1.53 tons with a wider transport width of 1.06 meters. Common wear includes slew ring bearings, drive pinions, and kingpost bores. Slew ring replacement costs approximately £700–£900. Have your dealer verify undercarriage roller and idler wear.
What engine quirks are associated with the JCB 801 series?
Early models use the Perkins 103-09 engine (16 HP). The 8015 (2004 model) uses a Perkins 3-cylinder injection diesel. Owners report intermittent stalling due to clogged fuel filters, air in fuel lines, or failing fuel pumps. Black smoke during cold starts is common and indicates unburned fuel from extended cranking. Glow plug cycling is recommended. Have your dealer verify fuel system pressure and glow plug operation.
What are the common electrical and sensor issues for the JCB 801?
The JCB 801 lacks dedicated test points for hydraulic pressure; diagnosis requires cracking a high-pressure line on the pump output and inserting a test gauge. Fuel filter bypass is a known issue where the sight bowl is mistaken for an additional filter. Hydraulic oil level is checked via a sight glass behind the dozer lever, which may be obscured by dirt or low fluid levels. Have your dealer verify hydraulic pump pressure and fuel filter installation.
What fluids and capacities are specified for the JCB 801 series?
Engine holds 3.5 L of 15/40 coolant. Canopy holds 4.5 L. Cab fuel capacity is 5.0 L. Hydraulic oil capacity is 17 L. ISO 46 fluid is recommended for hot climates; HP32 for cold climates. JCB HP15 is used in place of brake fluid on backhoes. Track gearboxes use JCB SAE 30 Engine Oil (not multigrade). Track idler wheels and rollers use JCB HD90 Gear oil (API-GL-5, MIL-L-2105D). Have your dealer verify fluid levels and specifications.
What should be checked when buying a used JCB 801?
Check the slew ring bearing for play by lifting the bucket and observing side-to-side movement. Inspect clevis pins on valve/spool assemblies for wear. Verify hydraulic oil level via the sight glass behind the dozer lever. Check for metal swarf in the valve block if multiple functions fail. Ensure the fuel filter is not bypassed and the sight bowl is clean. Verify the rotary coupling matches the original JCB specification, as mismatches occur. Have your dealer verify the machine's structural integrity and hydraulic pressure.
