    2000 CAT314cLCR breaking rod that holds Swivel in place

    I have a 314 Cat that has been breaking the rod that holds the swivel in place #7 in this diagram. I have broken 2 in the last 500 hrs and noticed when I replaced the first one it had broken on a previous owner who used a bolt instead of the rod from Cat. I’m an owner op that tries to treat the...

    Ex100 dp sensor problem

    I’m still not 100% sure what the problem actually was but I changed about every sensor on it as well as the wiring connections. And it came back to life and has been running great until a recent stepper motor issue. Lol what do the codes say?

    Ex 100-2 stepper motor swap

    Hello has anyone ever replaced a stepper motor on Ex 100–2. I can’t seem to get mine to come off the bracket. There is a snap ring that I removed and a key way slot but I can’t seem to get the shaft to come apart. Any tricks? Thanks in advance

    Advice needed removing counterweight CAT 314C LCR

    I found this very helpful. Thank you for sharing! I actually ordered these eye bolts they should work well and a lot less than through CAT. Funny story, I went to replace my fan belts and previous owner replaced exhaust header with aftermarket one which sticks out farther than OEM and won't...

    @heymccall, hope you’re having a nice weekend I’ve had a chance to put some hours on my 314 and I had a few questions I was hoping you could help me with. Where is the water separator? I have the manual but still can’t seem to find it. I’m wondering if a previous owner removed it. Also what...

    This is the interface tool number from hitachi /deere 4476512 that will have the four pin plug on it. JD can get you one in a few days. If your close to Corinth you could use mine.

    Hitachi ex120-2 drzx connection problem

    I purchase a Dr Zx and it would not connect to my 1996 Ex100-2. I ended up downloading the MPDr buying the interface cable and that worked just fine. Good luck!

    2003 Cat 314c lcr serial number check

    Thanks heymccall, I may have to pick your brain some in the future. I’ve read some of your posts on here some pretty good stuff! I’m going to have to pop the counter weight off sometime in the near future as the belts are squealing and it drives me crazy. While it’s off I may look into having...

    Hitachi Ex 100-2 very slow hydraulics

    It's been a bit but I wanted to conclude the prognosis of this machine. I ended up hauling it into the dealer hoping they would have better news but unfortunately they did not. They started by going over all the electrical which I had already done thanks to help on HEF. They told me the...

    Hitachi Ex 100-2 very slow hydraulics

    When I rotated the angle sensor it did make the machine a bit fast(still not near as fast as it should be) but it didn’t stall out. Although very slow it does seem there is some load on the engine. I noticed when multifunctioning it seemed to come out of it and want to act normal. I adjusted...
