    Running a new CAT 305. Not sure I'm loving it....

    I'm running a 305 for a friend trying to do some finer grading type work. Machine is brand new. I might be 'speshal' but I just can't get use to it and curious if there are any hidden menus to optimize function controls? Are these even electric over hydraulic? My main gripes I guess are sort...

    Rebuilding boom cylinder. 322C

    Thank you very much! Now I guess I need to decide if I want to tackle this. I swear every time I do one, I say I am going to build a hydro bench....lol Does anyone know the 'proper' way to hold the rod eye when applying the "holy jezuz' torque to the piston nut? In past yrs we have just...

    Rebuilding boom cylinder. 322C

    I thought a plugged in HEK serial. Or I can find and email the whole serial?

    Rebuilding boom cylinder. 322C

    Hoping to get both some procedural data from SIS and/or possibly some opinions of approach on this one. I will be rebuilding one boom cylinder. I realize most would say "do both" but other one was done recent. Historically I have always rebuilt my cylinders and custom machined tools to do...

    Couple issues with the 322C. Grinding when starting and Itchy swing

    When I say "start solenoid", I should have said "start relay" that is mounted near the ECM. There were times when you would turn the key to start and get nothing. After testing with a meter, I determined that at random, sometimes that relay would certainly click, but have no continuity. I...

    Couple issues with the 322C. Grinding when starting and Itchy swing

    Two totally different issues, but combining simplicity. 1. I am dealing with a starter issue and I am trying to address it early. Last yr I got a couple grinds when trying to start, meaning the bendix did not slam the starter gear into the flywheel right. I found that the start solenoid...

    Can we talk about "value" mini excavators?

    Very interesting Doug! And a testament to thinking outside the box!

    Can we talk about "value" mini excavators?

    Thanks for the input guys! As mentioned, the 300.9 CAT was just a quick example. I am not even firm that a mini-X is what is needed here but here is the basic criteria. 1. On rubber tracks. Running on sand. Wheels just won't work. 2. Reasonable speed and turning 3. Hydraulics system...

    Can we talk about "value" mini excavators?

    Here is a brief rundown. Working in a container tree nursery where rows of trees are ganged together. To get the picture, basically containers are run about 100 long and wide, all touching each other. Between these ganged rows, there is only a 4ft walkway. The weight of each is roughly...

    CAT 3126 fuel system purging without primer?

    Thanks for the helpful CAT documents and advice. The machine lives again! After waiting for warmer temps, I was able to drain off about 1/2gal of water from the fuel tank as well as some rust debris. I then moved to the filters and found a little more water. I found a little water in the...

    Needing some fast help with lack of fuel, 322CL, no primer

    Thank you and I agree! I created another thread in the general section as the 3126B is used in many things. After inspection of the first fuel filter, I think we need to go down that road first but I was very frustrated that because the coolant burb tank and hydro oil was low, those warnings...

    CAT 3126 fuel system purging without primer?

    I did not really see any 'gel' so to speak, but viscosity of diesel will increase with temp decrease and if there was any Summer diesel still in the tank, that would make it worse. It poured basically like 5w motor oil. Obviously diesel is oil so not a huge shocker but I suspect the filter was...

    CAT 3126 fuel system purging without primer?

    All input here imo is on point and relevant. Fuel gel could have occurred. Tank is low and about 15 gal of known good winter fuel was added from the fuel truck just to do 30min worth of work only 4 days ago. It fired and ran at level 6 doing pud worth without any issue at all. The main thing...

    CAT 3126 fuel system purging without primer?

    Yes, I meant put this in the general as it is not really an EX specific issue.

    CAT 3126 fuel system purging without primer?

    Couple pics of the filter assy. HEK serial. CAT dealer indicated possibly bulletin REHS2598 is what I am looking for in SIS if someone has that? So far it sounds like there are some known issues with the filter housing/pump. I know the pump is doing 'something' as it certainly refilled the...

    CAT 3126 fuel system purging without primer?

    Would the lift pump not work to purge the fuel system? I noticed that it was working to refill the primary separator but I have no info to know if that pump should load the secondary and fuel line. I am pretty frustrated that the secondary drain lines are not working and I do not want any...

    CAT 3126 fuel system purging without primer?

    This engine is in an excavator, but used for everything. Machine fired for me in the cold, then started to stumble, surge die a couple times. I am confident it is a fueling issue. I removed the water separator (1st filter) and rusty crap dumped out of it. There are two drain lines on the...

    Needing some fast help with lack of fuel, 322CL, no primer

    I am still trying to sort out what is going on here. 322CL, HEK serial. Machine ran 2 days ago perfect. We got a cold snap down in the low teens but was up around 30F today. I fired it and it lit as normal, then started stumbling and it has never done that before, ever. It was very obvious...

    Odd question. Mixing wood mulch with sand? How?

    Gotcha, it sounds like making a single pile in a ratio is the basic method here? The hoe sitting there is my 322 so I can certainly just make of big pile and all components flow like water. Nice stuff! It is all sitting on the dirt so I want to try to minimize contamination, though some is...

    Odd question. Mixing wood mulch with sand? How?

    I have been asked to "figure out how" to mix a wood mulch substrate with a medium sand for certain horticulture products. This is probably a one time thing and about 125yds worth. Right now, the only equipment onsite is the excavator. I mean, all I can think of is mixing like you are in the...
