Is there anyway to turn up a 3054C DIT in a 420E backhoe?

I would think the only way to turn it up would be for the CAT dealer to plug their computer into it and turn it up.

I may have to call my dealer and see if he can send someone out and put a tune in it... LOL

When you do call them, please post back here and let us know whether or not they're willing to do that. The reason I ask is that my understanding has been that in the case of stuff like earthmoving equipment, you generally don't want to do that because engine power is normally set to work within the limits of the hydraulics. I've been told that turning one up often just results in pressure relief valves opening more often, accomplishing nothing except the consumption of more fuel and the generation of extra heat in the hydraulics. I guess that isn't necessarily true in all cases though.

The 3054C engine uses a Delphi DP200 injection pump (pump and nozzle system) there is no way of electronically turning it up. Also dealers don't touch those pumps they just remove them/replace them or send them out beacuase they themselves don't do the adjustments. Really the most common power adjustment done is on 3116's in the older 953 and 963s where you can adjust timing and max fuel so the engine doesn't bogg so much when going against a pile.

(actually there are alot of power adjustments you can make on machine engines but not really on backhoes whats the point) I would say if you want more digging power adjust compensator and load sensing (signal pressure) on the pumps.

Hey are there retaining rings on those injectors or just a pain to pull out?
