This 337-page Claas Jaguar Repair Manual covers the Jaguar 880 and 860 forage harvesters, tearing into every gearbox, cutting cylinder, and corn-cracker on your machine. Open it and you get hydraulic schematics for the high and low pressure systems, exploded views of the feed unit and final drive gearbox, and a full troubleshooting section for the Orbitrol steering unit. Torque settings run throughout: torque the feed auger slip clutch to 780-820 Nm on the Jaguar 860, and give hydraulic olive fittings a half-turn past the point of resistance, not a guess. Your discharge chute won't wait for a parts truck. Bookmarked by system, so you jump straight from cutting cylinder to rear axle without hunting through 337 pages.

Claas Jaguar 880, 860, 840, 820 Common Problems This Manual Covers
Claas Jaguar 880 hydraulic union fitting leaks oil at the olive/ferrule connection after reassembly
Loosen the union nut until a little oil escapes to release trapped pressure, following the procedure on page 17. Retighten 1/2-turn past the point of resistance; do not overtighten or the olive will cut into the tube wall and lose its seal. Torque the fitting to 1.5-2.5 Nm as referenced on page 170, then pressure-test the line before returning the machine to service.
Manual Section: General Recommendation for Repair p. 17Profile ring or tube connection weeps hydraulic oil at a fitting that was recently disturbed
Loosen the union nut just enough for a little oil to run out and bleed off residual line pressure, per the guidance on page 18. Retighten the profile ring connection 1/2 a turn past the point where resistance is distinctly felt, or 1/3 of a turn past the pressure point for taper fittings. Inspect the ring for nicks or flattening and replace it before reinstalling. Recheck the joint for seepage after five minutes under load.
Manual Section: General Recommendation for Repair p. 18Electrical arcing or short circuit occurs while wrenching on the engine with the battery still connected
Disconnect the negative battery cable (-) before starting any engine work, as instructed on page 15. Pull the cable clear of the terminal post so it cannot swing back into contact during service. Check the cable connector for corrosion or a loose clamp, a common source of intermittent grounding faults. Reconnect only after all engine work is finished and tools are clear of the bay.
Manual Section: General Recommendation for Repair p. 15Hydraulic drive system runs hot and loses lifting power even after topping off fluid
Check the hydraulic oil level using the procedure on page 23. Drain and refill with multi-grade hydraulic oil HV (ISO-VG 32 and 46); an oil change takes 16 litres and a full refill takes 52 litres per the specs on page 4. Confirm the pressure relief valve lifts at 175+15 bar. Replace the filter element and bleed trapped air from the return line before restarting the machine.
Manual Section: Hydraulic System Maintenance & Troubleshooting p. 23Feed auger slip clutch slips excessively under load, chopped material backs up in the feed unit
Check the slip clutch torque setting for the feed auger; it should read 780-820 Nm (575.30-604.80 ft lb) per the spec on page 7. Inspect the friction discs for glazing or oil contamination and clean or replace them as needed. Adjust the clutch spring tension in small increments, testing under load after each change, referencing the feed unit gearbox procedures beginning on page 113. Verify smooth operation at full throttle before returning to the field.
Manual Section: Feed Units p. 113Frequently Asked Questions
What are the torque specifications for the chopping cylinder bolts on the Claas Jaguar 860?
For the Claas Jaguar 860, the knife mounting bolts for the cutting cylinder should be tightened to a torque of 250 Nm (185 ft lb). This ensures proper securing of the knives during operation. The torque setting applies to Hexagon bolts M 16. p. 7
What are the replacement specifications for hydraulic union fittings (olive/ferrule) on hydraulic lines?
When re-installing a used olive (ferrule) fitting, retighten the union nut only until snug after it has been loosened, and do not overtighten the unit. If the fitting leaks, loosen the union nut until some oil comes out, then retighten it correctly. For new installations, liberally oil the inside of the union, tighten the nut until resistance is felt, and then turn it an additional 1/2-turn past that point. p. 17
What are the replacement specifications for profile ring connections on hydraulic tubes?
For all pre-assembled and factory-delivered profile ring tube fittings, the end assembly requires the connections to be well oiled, and the nut tightened 1/2 a turn over the point where pressure is distinctly felt. If a connection is leaking, loosen the nut slightly until a little oil runs out, then tighten it again according to the instructions. Deviating tightening methods can reduce nominal pressure performance and durability. p. 17
What are the oil change and refill capacities for the working hydraulic system and hydrostatic ground drive on the CLAAS JAGUAR 880?
For the CLAAS JAGUAR 880, the working hydraulic system and hydrostatic ground drive require approximately 16 litres (14.09 Imp. qt; 16.96 U.S. qt) for an oil change. The total refill capacity for this system is approximately 52 litres (45.80 Imp. qt; 55.12 U.S. qt). p. 4
