My PC75UU2 wants some attention.
Saturday, my PC75UU2 had one of those days it did not feel like going to work.
I'm just puttering at this point, as my
L39 is out of commission due to fire. I was going to move some large rocks with the excavator and do a little finish work around the pond.
I should know better not warming the hydraulic oil up first. My thumb uses the same hoses the previous owner used on the wrist, i.e. # 6 lines. The bucket hoses are #12.
A heavy hand will overwhelm the cushion valve on the thumb. The cushion valve is a cheapo Prince 1500-3000psi adjustable 2 way relief valve. Excavators put out more pressure at the main pump.
Put some load with cold oil or full force with the bucket, the valve goes POP!
I lost about 2 gallons of fluid on that incident. I got on my computer to
Surplus Center and ordered another valve and a spare, then used a ratchet tie down to hold the thumb out of the way and decided I was going to continue working dressing up the with some rocks around the edge of the pond.
I was just about ready to shut the machine down and finish doing the little stuff by hand. I was pushing a small rock into place forcing it into the ground with the bucket teeth and oil started spraying all over.
The retract hose on the bucket cylinder let go, unrelated to the earlier problem. Stuff just happens with a 15 year old machine. I must have lost another 3-4 gallons of oil. The entire machine needs to be pressure washed. YuK!
I walked the machine to a shady spot, and got my wife to help me get the hose out of the tube bundle through the boom. (She must have been in a good mood)
I am for the most part finished with the pond. At 65' long x +40' wide x+8' deep it is big enough. ( I've nicknamed it "The Grotto") The water in the other two pond is crystal clear, and in time so will this pond. It will make a nice swimming hole.
I will use the two remaining dirt/rock piles to help fill and grade the remaining part of the field plus finish a rock wall up by the driveway.
To grade the rest of the field, I will clear the scrub, dig up the rotted stump piles to harvest whatever loam I can find, fill it the holes and low spots with pond spoils, grade, fill and, rock pick, finally spreading out whatever crap loam I have, picking out the sticks and rocks and York raking before I seed.
I will need both the
L39 and the PC75UU2 for that.
Now I am down to a Kubota
B7200 with a worn out hydraulic oil pump, and the RTV900. For the time being time to find another project around the house.
On an aside, I am looking for an experienced welder who has a truck with his equipment to do some on site weld repair in central NH, north of Concord. I'd appreciate any recomendations.
