DCP00171.JPG (313906 bytes)We have started to take the loader off the Cat in preparation of putting in the garage this winter.  We have taken the bucket and dump arms off.  We have new rails and sprockets for it and have to dig into the Diesel engine and find out what is wrong with it.

DCP00262.JPG (283780 bytes)DCP00264.JPG (265540 bytes)The radiator and the fuel tank/seat are off.  There was 4 inches of water in the clutch compartment from the power washing we gave the Cat before we brought it inside.  There was also a gallon of water in the transmission from sitting outside for years.  We have discovered that the brake pads are work out, but have replacements ready in the wings.  There was an inch of gunk in the fuel filter housing when we tried to drain the housing.
