The Bobcat 863 is a skid steer loader model manufactured by Bobcat Company, a renowned manufacturer of construction equipment. The 863 model was produced from 1996 to 2003 and was part of the C-Series lineup. Here are some key details about the Bobcat 863:

1. Engine: The Bobcat 863 is powered by a diesel engine. The 863 was initially equipped with a Deutz BF4M1011F engine, which is a four-cylinder, turbocharged engine. Later models may have variations in engine specifications.
2. Operating Capacity: The operating capacity of the Bobcat 863 depends on the specific configuration and attachments used. However, it typically falls within the range of approximately 1,500 to 2,000 pounds (680 to 907 kilograms).
3. Hydraulic System: The 863 features a hydraulic system that powers the loader arms and attachments. It has auxiliary hydraulic ports for connecting various hydraulic-powered attachments, such as buckets, forks, grapples, and hydraulic hammers.
4. Controls: The 863 is equipped with joystick controls that allow the operator to maneuver the machine with precision. These controls enable the operator to manipulate the loader arms, drive functions, and auxiliary hydraulics.
5. Attachments: The Bobcat 863 is compatible with a wide range of attachments, making it versatile for various applications. Common attachments include buckets for general-purpose loading, forks for material handling, augers for digging, and sweepers for cleaning.
6. Safety Features: Like all Bobcat equipment, the 863 is designed with safety in mind. It features safety interlock systems to prevent accidental operation and rollover protection structures (ROPS) to protect the operator in the event of a tip-over.
7. Maintenance: Regular maintenance is essential to keep the Bobcat 863 operating efficiently. This includes routine checks of fluid levels, engine oil, hydraulic system, filters, and tire pressure.

Hi Joseph:
Usually hydraulic components will "self clear" any air in the system just by trying to cycle through the functions a few times.
Have to ask the question............
Did you remove and replace the hoses one at a time, or did you take them all off at the same time?
The reason I ask is............ Could there be a remote possibility that any of the hose onnection locations were switched?

Most likely a control valve is leaking. If it just comes down over a long period of time that is not unusual. Most all loader buckets will slowly drop when parked in raised position.

I know on a bobcat 773 there are 2 spool lock soleniods. They are on the front of the bucket control valve. They literally lock the valve by a spring loaded pin that goes in a groove on the spool. When they get juiced the pin retracts and that spool can move. One for lift and one for curling the bucket. Check the wires coming out of the solenoids. Unplug them one at a time and see if the code comes right back. That should narrow it down to which one is bad. I changed both but compared ohms.

Bics coil on control valve not unlocking. Broken wire, bad connection or bad coil

Have you checked your "knock sensor" or cam sensor? It tracks cam and or crank movement for timing.

I was a lock smith for a wile and if your key has rounded cuts insted of flat ones (smooth insted of jaged) than its worn down and cant move the wafers to the right spots. even if it starts the car this may be true! Diffrent locks use diffrent parts of the key. Haveing a factory origanl made will fix this, not a copy but one cut with a lagurd machine.
Best of luck!

is the pump turning ? check tank filter
