    Caterpillar 246D, misfire, and acceleration.

    Dear Sirs, I am encountering a problem with a CAT 246D skid steer loader; it has difficulty starting in the morning and accelerates on its own.

    CAT 320D WITH SLOW HYDRAULIC MOVEMENTS A8F02378

    I hope you are well. I installed the speed sensor, and when calibrating the PRV, the pressure is constant, above 4000 kPa, and moving the calibration dial doesn't change the pressure. I noticed that the voltage reaching the PRV is the same as the alternator's 27V.

    CAT 320D WITH SLOW HYDRAULIC MOVEMENTS A8F02378

    Dear all, I hope you are well. I have this 320D with sluggish movements, but the diesel engine runs perfectly. Could it be a lack of calibration of the PRV (Power Steering Valve)? I tried to calibrate it, but I couldn't because the speed sensor is faulty. The pressure of pump 1 is 3848 kPa...

    PS54810 CAT 120K prefix: JAP

    Good afternoon everyone, in short, the transmission is practically dead, or at least clutch packs 6 and 8. I removed the transmission filter and found a lot of dirt (pieces that looked like plastic), which I understood to be remnants of friction discs. I also noticed that the transmission...

    PS54810 CAT 120K prefix: JAP

    Good morning, I only checked the coil resistances, but it seems the gears are sticking. When I engage the problematic gears, the machine tries to move and then stops. It works perfectly in the other gears. I'm not sure where to connect a pressure gauge.

    PS54810 CAT 120K prefix: JAP

    Dear all, I hope you are well. I'd like to know if anyone has the service card PS54810, as it's no longer available in the SIS system. I'd like to know specifically what the problem was, as I have a motor grader with the prefix in the title, and the forward gears 2, 6, and 7, and reverse gear...

    TEREX FINALY 694T SUPERTRAK

    Good afternoon, I'm having several problems with a Terex 694 screen. The right track barely moves, and I can't deploy the conveyor belts. I also found a hydraulic leak in a pump attached to the motor. I don't have any manuals to troubleshoot the problem, and I couldn't find any online.

    Cylinder head torque and valve clearance for JCB 416 wheel loader

    Good morning, dear colleagues. I need to install a cylinder head gasket on a JCB 416 wheel loader, as coolant is leaking into the oil. I have no information on the cylinder head torque or valve clearance. And I couldn't find the serial number plate for the equipment.

    CAT Main Harness Part Number 336D

    That's correct, the engine harness is relatively inexpensive; in my country, it costs around $500, and it's the original CAT harness. The harness we mentioned is the main harness for the machine. It's not the engine harness.

    CAT Main Harness Part Number 336D

    Thank you very much for the information shared. I suspect two things that I will rule out: 1) The wiring from the PRV to the ECM is in poor condition: My plan is to run both PRV wires externally to verify that the original harness wires are not causing the problem. 2) The backup EPR valve...

    DISPLAY FAILURE 584-5631, IN DIFFERENT CATERPILLAR MODELS.

    Dear community, I'm curious about your experiences with display failures on various Caterpillar equipment. I've replaced five displays on 320GX, 323, 320GC, and 336 excavators, all new-generation excavator models, with service letter PS55190. Last week, I had this same problem on a 120 motor...

    CAT 226B Parking Brake Indicator and Armrest Indicator Are Flashing

    Hello, it seems to be normal for the retaining coil to fail. Lately, my clients don't replace them; we simply leave them disconnected, so we can work without any problems. Besides, they're not cheap to buy every time they fail.

    CAT Main Harness Part Number 336D

    Hello dear friends, I hope you are all well. I repaired the damaged cables. It worked fine for 30 hours, but then experienced a fault. When I tried to activate two movements at once, the motor tended to stall. I connected my communicator and found two active codes: -6 for the PRV and the fan...

    CS54B prefix M5B, produces intense humming when compacting.

    Hello dear friends, I hope you're all well. I saw your post, and my machine did have bearing problems. We installed new bearings and the problem was solved. In my country, those bearings are quite expensive; I hope they last longer than the ones that failed. Greetings from Uruguay!

    CS54B prefix M5B, produces intense humming when compacting.

    Hello everyone, I hope you're all doing well! This time, I'm sharing a situation with a CS54B compactor. The machine emits a loud humming noise only when it's compacting, but when it's moving normally, without vibrating, it doesn't make any noise. I think it's the large bearings inside the drum...

    CAT Main Harness Part Number 336D

    Correct, the cables looked like this. Perhaps the heat, combined with the oil contamination, caused them to become that way on my machine. The problem is only in the area of the hydraulic pumps and filters. I believe repairing the damaged area would keep it working properly.

    CAT Main Harness Part Number 336D

    I don't have any photos of the damage, but it was a short circuit in the wires of the hydraulic pump's sensors and valves. The insulation was so badly damaged that the slightest contact would strip the wires, exposing the copper. I couldn't get the car running because I'd blow a fuse. I made a...
