    Cat manufacturing

    All I can see is the first one was built in 10/10/2012 and the second was built in 7/16/2013. Doesn’t show location or anything else. Most likely built outside of the US

    Cat 320 NOx conversion

    As yeah in your case then I’d pull it and clean. Still take a PSR just so we can check what is happening when the problem is active.

    Cat 320 NOx conversion

    and you have run the aftertreatment functionality test? All you need to use when cleaning is water. The crystallized def fluid becomes soft when water soaks on it. I usually use a leaf blower after to blow as much water out, then put it back on and run the machine at idle for 30 mins and it...

    Cat 320 NOx conversion

    When it failed, was there any build up on the tip? You are sure it’s clean in the mixing chamber? So that particular code is one of the hardest to clear. CAT tells you to run the aftertreatment recovery procedure multiple times to try and burn off everything. I personally just pull the scr...

    bobcat excavator with AC leak - where to start looking

    Hire an ac tech to come find the leak. First off you need a gauge. You should have low side pressure at 25-40 psi and it should be cold. Then you can soap and water spray all the ac lines and valves and condenser. If you cannot find the leak, it might be the evaporator (but you should smell...

    Coolant going into oil pan with fresh head gasket, Cummins 4B, case 580e.

    Even if the head was warped, no way it drips that fast. You probably have something cracked. You are gonna pull the head regardless. And send it to a machine shop. If they don’t find a crack, check all the cylinders and see where it’s cracked. If you drop the pan and pressure test, you will see...

    Cat 420F2 aftertreatment issues

    You can have the dealer come out and delete the code. As long as the fault isn’t active, they just need a password.

    Cat C6.6 Acert 930H Engine Noise when Warm

    Soooo. When cat came out, was the engine hot making the ticking sound? And cutting out each cylinder did not make the ticking sound less? You can run the test the way the dealer teaches you and it runs thru each cylinder for a few seconds, or you can toggle the cylinders individually. I...

    Cat C6.6 Acert 930H Engine Noise when Warm

    The tick only happened after the injectors were changed? Or was it there before?

    What service tool is used for cat/mitsubishi forklift?

    There is no 9 pin adapter. It’s only cat branded, but everything is identical with the Mitsubishi ones. We have the adapter for truck tool, but apparently no one can get us a username and password.

    What service tool is used for cat/mitsubishi forklift?

    So we take care of a bunch of cat and Mitsubishi forklifts (same exact models just different brand). We were told to use truck tool for our diagnostic tool. We got the adapter and truck tool downloaded. We cannot get a login. We have tried to sign up with multiple email accounts, always...

    CAT 420 Fuel system issues (Gas in fuel tank)

    With the key on, can you hear the electric feed pump hum? Also are you having any white smoke? How does it sound at idle? You can pull off the bottom pipe of the muffler before the dpf, or the clamp at the turbo. So we can see if the muffler is so blocked it is causing the machine to almost...

    Cat 420F no throttle response with 2 active codes

    Check if it’s fuel pressure sensor codes for the circuit or for the actual pressure. Because if it’s the fuel rail pressure high and low codes, you can change the filter in the tank. It gets dirty and can also collapse on its self and cause a restriction. Also the electric feed pump can become...

    Cat 420F no throttle response with 2 active codes

    Yeah you can take the floor boards off with a couple of torx bits. Thats the platform harness that goes from the cluster and fuse panel down to the accelerator pedal, machine ecu and up the steering column. Check the wiring from the pedal backwards for chaffing. Also take a pic of the pins for...

    Cat 272D2 Fault Codes

    So the majority of cat machines that I work on, circuit high and voltage above normal will mean that the circuit is open. Most likely to a wiring fault or connecter unplugged. Also can be from a component failing but not shorted. Current/voltage below normal can be from the fuse popping, sensor...
