After spending most of last summer chasing electrical, hydraulic cooling fans, air leaks in fuel system and a couple of other items, I actually can use my SEE for what it was intended for which is as a crawler loader. Having never owned a crawler loader I cant compare it to a conventional Cat or Case but I have been impressed in some ways and have lot to learn in other ways.
Some things of note in no particular order,
I have managed to figure out that the front right tire will rub somewhere on the body work or frame when using the loader in "unusual" body angles. If I load up the loader with loam and drive downslope over an uneven surface with the right tire lower than the left one (about 20 degrees tilt) and try to turn left, the mog is definitely an unhappy camper. I do this at a very slow crawl and if I straighten out, the rub goes away. Rubbing with lugged tires is definitely something a person notices.
Tilt locking the boom is getting a lot easier. I can usually get it the first time but the only way I can do it is position all the cylinders in stow position (bucket curled up and the upper boon up against the lower boom). I then tilt the assembly quite far down and then bring it back quickly and then push the lever back at the last minute once the assembly goes overcenter. I haven't been able to do it slowly.
Some folks who are familiar with the Case 580 controls noted that they swear the hydraulic level pad controls are weird. On my unit the left control works opposite than the right control. I am starting to remember but still its a future to see if I could synchronize them
My SEE came with the optional Ripper Claw bucket which is designed to rip rocks out, its a beast but the definitely screws up fine control like when I am pushing rocks around or trying to sneak under one Cutting a neat hole just isnt going to happen with hooks on the back of the bucket. At some point I will order up a standard bucket.
I can max out the loader bucket hydraulics with a heaping full bucket. It wont go up but will maintain level. If I tip it forward and dump a bit so its level then its quite happy.
I should have played video games when I was young, my eye hand coordination and the ability to make changes to three controls at once is going to be major learning effort.
My swap out of the cooling fans with slightly smaller but more efficient fans (due to one of the originals being rusted/shorted out) seems to work well. They move plenty of air and keep the hydraulic temp reasonable. For those not familiar there is a TSB on the rear hydraulic cooling fans, the rubber grommet where the wire enters the fan is facing upwards and age damages the grommet leading to water in the fan motor. The TSB recommends gooping the grommet with silicone. If this fan is shorted, there will be intermittent electrical short on the high amp fuse that serves the electrical system at the rear of the truck. It will only blow when the cooling fan thermal switch is on which only happens when the hydraulics are being worked. I made up an adaptor plate out of a sheet of aluminum for the fans I had sitting around so its not particularly stock but until I source an OEM fan at a reasonable price they work well.
The cooling system seems to be very effective on the engine. I work it hard with the throttle cranked up for hours with the switch at the backhoe and the temp is still mid range even on warm days.
Hearing protection is definitely mandatory when using the backhoe, I am considering pulling out my super ear muffs I use on gas turbines
