Bought a backhoe couple weeks ago. It's a 1984 555A with 4n1 loader bucket, 15ft extendable, 24" heavy duty hoe bucket. Tach says 5242 hrs but if it's accurate they have been extremely hard hours.
The extendable dipper has been broken at the elbow joint. The repair appears rather old with no reoccurring cracks/breaks.
The hoe bucket has had cracks repaired. They too appear to be old and holding.
The 4n1 appears to have been used open at a high rate of speed. The dozer edge is bent backwards at each end.
I believe this use is how the subframe got cracked. It's cracked on both sides where the loader lift cylinders fasten. The repair is old and holding. Plated on the outside of the frame in addition to welding the cracks.
It appears the latest damage was getting a large rock or stump under the belly on the left side, near the battery box. This destroyed the torque convertor dump valve, bent the bracket holding the trans filter, then sheared the bolts that hold the brake linkage swivel shaft. This left the hoe without the ability to dump the torque converter, an oil leak at the dump valve and no brakes.
Had to put a kit in one of the loader lift cylinders and one of the 4n1 cylinders ($100). The boom cylinder and dipper cylinder seep but I'm gonna run em that way for awhile to see what else pops up.
Replaced the front axle kingpins ($300).
Repaired the brake linkage bracket.
Replaced the torque converter dump valve ($580).
Built a skid plate to protect the dump valve, trans filter and brake linkage.
The engine sounds good, starts right up, no abnormal exhaust smoke or blow-by. The trans/torque converter work great. Brakes work great. Diff lock works great. Hydraulics have very good power, appears pump has been replaced not too long ago. All the glass is in the cab. Heater works great. Rear tires are very good. Fronts are solid but old.
I paid $6500 for the machine. Have spent an additional $1300 so far. Will spend an addional $200 adding a block heater and replacing the hoe bucket teeth. Then I'm ready for warm weather to try it out.
