when i crank this machine, it has a slight skipping sound. As if...an injector is a little off. it warms up a little, it gets smooth. a quarter way up the rpm range, it has a very slight skip. but not always....
wide open throttle....or basically half to wide open..its perfect and stout.
in average operation....i use the decelerator pedal as a clutch....feathering slowly when shifting or forward to reverse...controlling track spin.....it isnt noticeable. but when i power wayyyy down....it is (sometimes) making a skip sound.
I have changed both fuel filters over and over...but it still persists.
the machine has 7000 range original hours. i have never had a fuel issue with the dozer since we purchased it low hours.
the fuel pressure gauge that is mounted on the side of the injector pump is foggy. cannot be read. i will replace....do i have to buy this from cat? or is there a good quality aftermarket choice? i prefer to buy a lot from NAPA, heavyquip, etc.... what guage would be best for outdoor/weatherproof application? just a green to red indictor or a specific PSI range?
how does the fuel pump system work on this model dozer? is it gravity from the tank to the injector pump and then it suctions?
on this particular job....my fuel supplier has been bringing me less than clean fuel. I have replaced fuel filters each week on two machines. When i pour out the filter to inspect...its usually rusty fuel.
any help would be appreciated. thoughts or ideas?
Thanks for the help guys....
