Im glad FWF is here! Do everything he says as he is the resident expert on Komatsu stuff. JohnC. is good info also!My pressure seems to be about 15 psi below minimum, is there a way to check the relief valve or will whole pump need to be removed.
Just to chime in...……...is there any current active fault codes on the monitor? It sounds like something else may be going on.Did you ever resolve this issue? We were lead to replace a turbo assembly on the machine and issue is still present, checked oil drive and control pressure. Have 160-180 psi, the vgt is constantly cycling back and forth and the pressure fluctuates. All engine sensors have good readings through Insite. Im leaning toward the EPC for the KVGT but am looking for some input before I continue.
Any and all input will be greatly appreciated.
Oh no, not even close, I'm just a fill in when John C is busyIm glad FWF is here! Do everything he says as he is the resident expert on Komatsu stuff. JohnC. is good info also!
my pc210-10 just threw this code. Disassembled turbo and all looks good. Going to try to find screens tomorrow. I've had low boost pressure as long as I've owned it. Komatsu says I should hit 31psi and 26 is best I've seen, normally varies from 15 to 21. I had intercooler pressure tested.you guys are good, typically the screen in the bottom of the rgr housing plugs easily, if its clean and good pressure from the boost oil pump, pull off the epc for vgt control and clean it well, and iirc correctly there is 2 screens under the block with the oil feed line on the tubro, the 125/140 engines plug them all the time. if no change change the turbo, ive changed a few for the helicopter noise your hearing.
yes, just chosing the custom monitoring in the screen. On the predetermined monitoring I noticed oil switch is off! Is thT for oil pressure or level? How can I turn it back on?What are you using to measure boost pressure? The onboard electronics?
