Why does the cat 3126 have one solenoid?
The CAT design only has one solenoid where the Later Navistar design in the video has two. engine oil consumption via leaking piston sealing inside injectors. low power, oil breaks down and cannot be pressurized any more or is aerated. injector o-ring failure, causing cross contamation of fuel and oil, usually oil ends up in the fuel tank.
Why does my cat 3126 have low power?
Connect a clear plastic hose to the return to fuel tank hose on discharge end of fuel pressure regulator for clear stream of fuel coming from engine while engine at idle and high idle. If you have lot of air or foam in fuel clear line returning to fuel tank than that would cause low power.
Where does the oil go in a cat 3126 engine?
Cliff note version; engine oil is pressurized to around 3000 psi and sent to the fuel injectors (via HEUI pump) it uses that high pressure oil to push a piston inside the fuel injector (oil on top, fuel on bottom of piston) to atomize the fuel, the injectors are controlled by a solenoid on top of each.
What are the codes on a cat 3126?
The intake heater relay energizes when it is supposed to and I can feel the intake get a little warm to the touch after a couple of cycles so I believe it is probably ok. The cruise/rpm switch method revealed 2 codes. #39 and #38. I don’t have access to a code reader.
What should the fuel pressure be on a cat 3126?
It should read 60 psi after briefly cranking the engine.If you get 60 PSI QUIT CRANKING. – the fuel pressure regulator is on the rear of the head.
What happens when you hit the brakes on a 2001 cat 3126B?
My 2001 3126B shuts down when I hit the brakes hard. It has done this at 35 MPH and at a coast in the shop. Feels like an electrical/electronic shutdown as it is instantaneous. Does not loose power it just shuts down. Starts right back up and runs fine but don’t give it a hard brake because it will shutdown.
