    Travel problem with a John Deere 110 backhoe

    Hey Folks, As always, thanks to all that mke me look smart. We have a JD 110 backhoe that travels fine when you go slow. As you increase the throttle, it starts to jerk (i.e., pull and then not pull) as if it is dropping hydrostatic pressure. Has any one ever heard of this? Thanks...

    Hey Folks, Yeah, it'se again, the guy that can't leave these 855s alone and get a life. I have another question on a Cummins 855 engine that has to do with injectors. We have 5 Autocars here where I work and each one has an 855 engine. The oldest one is a 1971 and the newest (if you...

    Setting injector travel on a Cummins 855

    One more note. Don't ever try setting top stop injectors using the travel method. I'm here to say that it does NOT work! It turns out that each injector is about two turns of the screw too tight and needed to be backed off these two turns. Now, that NTC-400 purs like a kitten (and still...

    How do you diagnose a miss in a Cummins 855 engine?

    One more thing. Don't think you can set top stop injectors using the travel method. I'm living proof that it does not work! It turns out that if you do it, then you have set the injectors about two turns too tight. I redid the injectors using the torque method and each one had to be backed...

    Setting injector travel on a Cummins 855

    Opps! Screwed up. Let me add a correction. For top stop injectors ONLY, you do the previous injector from the valve that you are adjusting just like you do for the travel method with the dial indictor. The only time you do the SAME injector as the valves is when you are: 1.) using the...

    How do you diagnose a miss in a Cummins 855 engine?

    If you folks are OK with it, I'd like to close this thread down and open up a new one that addresses only injector travel setting. I'm starting to better understand this Cummins 855 injector setting and I have a couple of questions. Thanks. Chris

    How do you diagnose a miss in a Cummins 855 engine?

    Folks, great advice thanks. This engine has does not have top stop injectors. It has the old style. We will give the pry bar on the injector a try. Thanks for the idea. Also, while I have you folks here. I get that there are two ways of setting the travel on these injectors. The one way...

    How do you diagnose a miss in a Cummins 855 engine?

    Hey Folks, thank you for the great feedback and ideas. We have a temp gun and found the 5th and 2nd cylinders running much colder. I like that idea about the pry bar on the injector but won't the pushrod fly out when you hold down the injector? Just wonderinbg how to prevent the pushrod from...

    How do you diagnose a miss in a Cummins 855 engine?

    Folks, as always, thanks for all the help with these Cummins engines. We have an 855 Cummins, 400 hp, and the engine developed a miss. We pulled the injectors and found a lot of metal to metal wear so we replaced them. Made no difference. We also purchased a compression test adapter for the...

    Got one for you Cummins 855 experts!

    Hey Folks, as always, thanks so much for making me look smart with the boss. Here's the story. I have a Cummins 855 NTA-370 (engine # 10417020) that I talked about in a previous post last year that had a serious smoking problem. (Yeah, I know. . . ). See we (foolishly) did a bunch of things...

    A smokin' Cummins - Help!!!!

    Hey Folks, I haven't updated this post in a while because, believe it or not, the motor stopped smoking. In fact, it is worse, it doesn't pull well at all. So, now I have the opposite problem. So, I went back through the motor and rechecked everything and made sure all was correct...

    Hey jey_c, thanks for the quick reply. Could bad pilot pressure affect upper carriage but not travel? Thanks!

    Komatsu PC300LC-3 has slow hydraulics

    Hey Folks, as always, thanks to all for making me look smart. I have a Komatsu PC300LC-3 who upper carriage hydraulics all run very slow. The machine walks perfectly but the upper hydrualics (boon, arm, bucket, swing) all operate very slowly. My first thought is that both pumps are fine...
