Bobcat T740 Less Power

[davisgravel]

T740 track loader, I had bad injectors, would miss under heavy load and eventually throw a fuel starvation code and die, I replaced entire fuel system, pump, injectors, rail, injector lines, filter. Now the machine runs fine, no codes no smoke no miss, BUT, it doesn't have as much power as it had before I changed everything. Before I changed I could run at less than full throttle and not bog engine down, had plenty of power till it threw the code and died. Now with all new fuel system it runs smooth, no codes no smoke, no misses, but it has considerably less power, you can feel engine bogging just climbing a grade, and you can bogg engine down by pushing into dirt pile. Have run it since last fall this way hoping it would learn new injectors and get better but no such luck, any ideas. The replacement fuel system came from Diesel Pro , online.

Power in engine or power on hydraulics ?

When it boggs down do you hear the engine lower rpms or does it stay the same ?

Another question......

Did you get your injectors programmed from bobcat after you replaced them ?

I'm assuming you did as you say there are no codes present

Hello. I have a 740 and I'm having same issue. It runs great and everything checked out at the dealer. New filters and all as well. But it just feels lower on power than when we 1st got it a few months ago. It just bogs down the rpms go down and it will stall if not easy until it revs back up. Very frustrating as it should have more power than this. Even a tl8 has same hp but feels like it's much stronger than this bobcat. So did you ever find out what your issue was please let me know if you can

Never figured out why it lost power, just running it as is

I forgot to mention, I did clean out the DPF filter, seem to help with slow throttle response a little bit, also if you figure out your issue I'd appreciate you letting me know what you found, Thanks
