    Lull 844 fuel tank rust

    thanks for the advice. I think the time to clean/weld and seal the tank will be less than replacing the entire tank. also, will be a lot cheaper as well. thanks

    Lull 844 fuel tank rust

    My lull 844 engine was bogging down. I drained the tank, changed the filters and it ran perfect. 2 weeks later, same thing again. The bottom of the tank has a pin hole rust leak. Is it worth trying to clean/repair or just get a new tank? Any ideas where ? Looking up online i could only find...

    Lull 844 - engine cycling

    Thanks, this is very helpful. I read about the accumulator in the manual and it sounds like it could be the culprit. I attached a pic of the model and serial.

    Lull 844 - engine cycling

    Please see the attached video (the website made me zip it) or here; The engine is making a cycling sound. I've had the machine for 3 years, and it always did this, but the cycle intervals was about 20-30 seconds. Now, it is every 1-2 seconds. It doesn't sound normal. I have no idea where to...

    Cat error mode reset?

    I got that info (Fuel Rail Pressure) from a google search - not very reliable I know. It was giving a similar error code a month ago. Catepillar came out, said nothing was wrong, charge me $$$ and now it has happened again.

    Cat error mode reset?

    Th417c.. I know it's a telehandler, which is a different section, but I got no responses there. I'm guessing all catepillar machines have a similar computer and engine. Has anyone heard of this crippled mode where it won't start?

    Cat error mode reset?

    Does anyone know how to reset a catepillar without a computer? I read online there is a pedal sequence to follow but it didn't work for me. The machine won't start, it just gives errors on the dash, the starter engages for a half second, then stops.

    engine not running right after powerwash

    I left it in the hot sun all day yesterday. Must have dried it out because last night it started up and ran perfect. The temp gauge light is also working correctly again.

    engine not running right after powerwash

    zero electronics, which is one of the reasons why I decided to get it. easier to work on. In fact, the key doesn't shut the engine off. I have to pull the throttle all the way back to shut it off. I have to do a full fluids/filters change anyways, so, maybe I'll do that first and see where it...

I powerwashed it out, along with a few other areas that needed to worked on. it started right up after spray down, but after a minute or so, I...

    Grinding noise left side, forward only

    I recently picked up a Skat Tak 1350. It hasn't had much use (farm use), and the biggest thing it needs is cleanup from sitting outside. The first thing I noticed is a loud grinding/growling noise from the left wheels. This loudest when spinning clockwise (left forward, right reverse). No noise...

    Komatsu Pc50 bucket size

    I have a Komatsu Pc50, it's around 11k lb machine. It had a 24" bucket that is pretty torn up. I found a nice 30" bucket, but not sure if that is going to be to big for the machine. Any advice? Thanks

    Komatsu PC50 Hydraulics Problem - dipper out, doesn't retract instead boom goes up

    all fixed! i must have been in super retardo mode yesterday. I had turned the aux valve, not the pattern changing valve (thinking it was the pattern valve). The pattern changing valve had vibrated to a middle position causing the f*ed up controls. I really appreciate the feedback, mobiltech...

    Komatsu PC50 Hydraulics Problem - dipper out, doesn't retract instead boom goes up

    yeah, that is a really good point. I wonder if I can re-plumb and by-pass the pattern changer to eliminate if that is the problem or not.

    I have a Komatsu PC50. This morning, the hydraulics started a problem. SAE configuration (hasn't been changed in years) I push the dipper stick out (left control stick forwards), then, when I pull the stick in (left control stick backwards) the boom goes up. To make the boom go back down, (and...

    keep the 742 or upgrade to 743, 753, or 773

    I have a Bobcat 742, gas powered with the mitsu engine. It's been ok and has served it's purpose for the cheap price I paid I can't do heavy or fast work with it. When I try to dig into a big pile or spin to fast, the engine will die and I have to let it recover. it does works for spreading...
