Truck arrived under its own power.
Does not look too bad in appearance.
A little over 10,000 hours on the clock.
Noticed right off that number 4 cylinder has a spark plug "slightly hissing compression" and I will need to get beyond the COP to see what the damage is there. Possibly someone simply "under torqued" the spark plug, but I've a feeling this may be a case where threads were galled and damaged by the earlier style spark plugs before Nissan went with an extended unthreaded ending to the metal plug casing.
Also noted is a leaking front crankshaft seal.
Looking at the beast it appears that the least cumbersome way to access that is going to be by removing the counterweight and radiator to reach it from behind the truck.
Anybody done one of the seals in this model using a different approach?
The steer axle front trunnion bushing steel shell has apparently shattered as I can see pieces of broken metal (consistent with steel that forms the bushing shell) hanging out of the trunnion pocket.
That looks like a pretty straight forward job of dropping out the axle assembly and then removing the bushings.

On another note, the Nikki regulator/vaporizer on this truck appears to be same one used on our Komatsu trucks with the K-21 engine. I haven't had a chance yet to confirm this so does anyone know that the regulator is identical on this MCFA application.........to what is on the Komatsu trucks.........or not identical?
Our Komatsu dealer is literally 1 block over from our shop, but the Mitsi dealer is way cross town.
