Recently purchased this machine and found #3 piston to be melted so now in the middle of an in-frame rebuild and need some help making sure I go back with correct parts.
The serial information on the bellhousing is:
DF0P1Z
4M22B
A430617
Engine:
4.4 NW
HH3 4 K 14
F0NN6015CB
Backhoe:
AB30617
ROPS:
Jan 1 1995
024156
I have read a bunch of prior posts on serial coding and the date code on the engine doesn't seem to match that on the ROPS so hoping someone can confirm the year and model. It was sold to me as a 1995 555D with a 256 Diesel engine.
Also, I pulled the following bearings out of this and they don't match the parts manual I have so curious if someone did a prior rebuild and didn't use the right parts or they have been superseded.
Crank Journal Thrust Bearing: F0NN6A339HA (STD, G, D, LX)
Journal Bearing: E9NN6A338AA (STD, G, D, MX)
Any and all help welcome so I get the right rebuild kit ordered for this machine.
Connecting Rod Bearing: E9NN6211AA (STD, G, D, LX)
