Interesting, I have a 763 four switches on it, the front switch locks in the auxiliary hydraulics for my chain digger. The switch started playing up so I ordered one online but the wires were a different colour, so I tested all of them to match what the OEM switch did but to no avail as nothing...

There’s an electrical connector on tails of all spool solenoids, figure out which is the auxiliary spool and unplug it. If the auxiliary keeps going then the issue is within the spool valve, if it stops its electrical. From memory I think it’s the solenoid at the rear of the spool valve housing.

I just had a wild thought on top what I suggested; you do know that the system has an electric lock out circuit don’t you? Mine is a 1999 model and the safety bar needs to be down and then the traction lock override needs to be pressed before hydraulic can be activated. Mine doesn’t have a...

I have a 763 which I’m guessing is very similar in the Hydroulics department. As KyMadMan said take no offence at any of our suggestions; when you’ve reinstalled the lift rams are they plumbed correctly and you’ve not crossed up/down hoses over where the rams are fighting each other? I’d track...

Yep, use the safety stops if the machine has them as the downside of using a prop is that most machines will rare backwards with front tyres coming off the ground when you you remove the weight of the arms with a prop unless you put a stand under the very rear of the machine. All machines that...

The large hose is the suction and return is teed into the suction hose behind the pumps. The small line is the return/bleed-off from the drive motors.

Yes, they can do a lot of damage if the tapered pin come out, 15 months ago I purchased an old 763F (2,300 hours) that had been parked up out in the weather for 4 years after the previous owner hadn’t noticed the same bolt (was not an OEM bolt) had fallen out, tapered pin backed out causing the...

There are 3 chain case covers, the middle one has the solenoid that releases the brake and is directly above the drive sprockets of the hydraulic motors. I can’t see any issues feeding a new chain through other than having to install a joiner link as I believe Bobcat only use “closed loop”...

I purchased a new one of these back in the day (sold it in 2007) and as already stated the floor pedals use two push-pull cables (absolute dumb idea) that operate the spool valve that is situated in the engine bay on the left tower just below the arm pivot pin. I suggest that you fully remove...

These machines usually have a case drain as standard unless it’s a highflow model. Mine is a HF and the case drain is simply tapped into the case drain from the left hand drive motor before the little inline filter.

These couplings are as common as; here in Oz my local hydraulic shop had heaps sitting on the shelf in couple of different brands/quality. The previous owner had a dog’s breakfast in couplings and I wanted to return back to some normality as my machine is a high-flow 763F currently operating a...

The issue with your right hand drive motor will be timing of the valve plate that was probably assembled one tooth out. You need to mark them when disassembling as they’re timed opposite for left and right sides of machine.

I just priced one here in Australia and it’s around $1050 Oz pesos. 🤦‍♂️ I fear mine is also going down, played up a couple of times hours prior but re-slamming the safety bar had me going again……. until it didn’t. Luckily I was still at home as I was about to drive it 4 kilometres down the...

I reckon the sensor will fix it although in saying that Bobcat don’t run the best wiring harnesses and have a tendency to rub through where they attach to the metal clips. I bought my machine 15 months ago and came with the HP-3 fault on the screen which uses the same digit characters as the...

For my 763F EP is engine oil pressure related and EP-3 is “Wiring Not Connected”, therefore I would logically think that your issue is one of two possibilities. One is a break in the wire or two, a broken wire within the oil pressure sensor on the engine which would also come up wiring not...
