Caterpiller IAPV Disassembly and Cleaning UPDATE

Ultrasport

Thanks for the detailed explanation.

Since I have the same engine, I was interested, but was not sure what the IAPV was.

After a little research, I think you're talking about an Injector Actuation Pressure Control Valve which controls high pressure oil pump output pressure by dumping excess flow back to the oil sump. Is this correct?

I'll be saving your instructions for future.

Thanks again

Fred
