    Hydraulic oil additives

    I have heard that case IH uses certain additives in its oil that swells up orings and if you use any other oil they will shrink and start leaking. Is this true? Also, if you put some cheap oil in a case payloader and it started leaking, is there some sort of additive that might swell the o rings...

    Cat 345 vs deere 450

    I'm looking at getting a CAT 345B II or a deere 450c lc. Cat has 13k hrs and deere has 15k and are the same price. Which one is better? What do I look for in these machines? I'm used to deere equipment but I think I like a cat. It's going to be used in a pit for moving overburden and loading trucks.

    Samsung se450lc-2

    I'm looking at getting a Samsung se 450 for work in a gravel pit moving overburden, feeding screeners, and digging out of the water. What should I look out for? Is it a decent machine? Is this really just a volvo? How does it compare to a cat 345?

    Case 921 delay in bucket controls.

    I have an old, I belive 1994, case 921 loader. This is pre 921b. The loader controls seem to be delayed. Everything works but it takes maybe half a second or more before it responds. Works faster if I steer a little bit. Any idea what could be causing this?

    Hitachi pump kicks off

    I have a Hitachi ex 220 and it was always a strong machine with plenty of power then all of a sudden the pump kicks off whenever you move it. Does so in all directions and with tracks whenever you do anything. Wait for a couple seconds and it re-engages. Is there some sort of high pressure...

    220 pump disengages and re-engages

    My hitachi ex 220lc-3 has been acting up lately. When you first start it up, the main pump seems like it gets bogged way down and then kicks off. You let off the controls and it starts working again. If you move really slow, its just kind of jumpy or spongy feeling. I changed the high speed...

    Hitachi ex 220 lc-3 jumpy hydraulics

    The hydraulics on my hitachi ex 220 lc-3 keep shutting off. It acts like it strains and then the pump kicks off or something. It gets better after about a half hour but still kicks off whenever you try to use too much power at once. Is this really bad or could it just be some kind of valve I...
