Hello everyone, I recently picked up a Bobcat 909 backhoe attachment. It needs some work to get operational again, you can follow my progress on my youtube channel if you like... While working on it a thought crossed my mind - I'm thinking about possibly converting it from vertical to fold down...

Those Deutz engines are famous for blowing head gaskets and then burning oil. Our 873 had the same problem, smoked like crazy and had blowby but always started great even when cold, and a new head gasket fixed the issue. It's not too bad of a job to do if you're mechanically inclined. There are...

Ok gotcha, sorry I thought you were saying there was no cooler at all… As for oil leaks, hopefully like you say hou have it solved but in case it rears its ugly head again, these engines were prone to head gasket problems. Most of the time they would leak into one or more of the cylinders and...

Unless someone has replaced the stock engine with a full air cooled engine, your 873 should have a radiator above the engine. It will look a bit more like an overgrown oil cooler than a traditional radiator but it will have one, if not someone has removed it. The engine in this machine uses...

Pop the inner race and rollers out then run a bead of weld all around the inside of the outer race. This will shrink it enough that you can pull it out with 2 fingers.

Check and make sure your auxilliary hydraulics are not engaged, your starter won't have enough power to turn the engine over with them engaged.

Not sure how much this will help you but this is the troubleshooting chart in my manual. It’s for the 730 series machines but for all intents and purposes your hydrostatic system is virtually the same.

Do you know how long the machine had been sitting before you got it going? There's a real good chance your hydraulic and hydrostatic systems just need all the air purged out of them. One way you could do it is to jack the machine up so that all 4 wheels are off the ground and just work them...

It appears from your pictures that you have a later model 743. You still have an inline hydraulic filter similar to the bronze filter, but it is in a different location. If I remember right the block that's in Markle's picture will have been moved to the side of the machine frame. There...

How fast are you running your engine while all of this is going on? These machines will make all sorts of noise and feel weak if you're just running the engine at idle or lower RPM, they need to be revved up some. They will whine a bit with the engine running at higher rpm and that is normal but...

One thing I have learned with our SB200 at work is if you keep your snowblower attached to your machine and park it inside, then go outside in sub freezing temperatures to blow snow it will clog up real fast until the chute cools off to the temperature of the snow you're blowing through it...

Years ago we were working on a movie job and I had our 873 and another fellow had a brand new Cat tracked skidsteer, can’t remember the model but it was maybe a tad bigger than the 873. One night we got a very healthy dumping of heavy wet coastal snow and the next morning he was going to show me...

The flashing LED means there's a problem with your auxiliary hydraulic system. From the symptoms you are describing and the LED flashing it sounds to me like one of the auxiliary solenoids are energized when they are not supposed to be and deahdeading the system. This is also why your lift arms...
