What should fuel pressure be on a 3406b?
That primary seems to be a little restrictive on my vac gauge? 92 3406B 3zj-05461 with the big rods-7E-5888 pump-36psi turbo boost is summer, up to 40psi in cooler temp, BW turbo i bought at 4-states of the shelf added a few more psi and kwik boost. Click to expand… Toss that Cat primary on the frame and use a Fleetgard FS-1023.
How does the fuel rack work on a PEEC engine?
The rack mechanism on a PEEC engine is very similar to a mechanical 3406B engine. The fuel injection pump is nearly identical; the rack is moved by a servo valve which receives oil pressure from the fuel injection pump.
What kind of engine is a PEEC diesel?
The 3406B PEEC Diesel Truck Engine is an electronically-controlled 3406B. The Electronic Control Module (ECM) for the engine controls fuel rate and timing electronically instead of using the flyweights and linkages of a mechanical governor.
How is fuel rate controlled in a caterpillar PEEC engine?
The Electronic Control Module (ECM) for the engine controls fuel rate and timing electronically instead of using the flyweights and linkages of a mechanical governor. The electronics also replace the mechanical fuel-air ratio control, torque control group, and various adjustment screws.
What are the fuel filters on a Baldwin 3406E?
The fuel filters on it when I bought it were a Baldwin BF7587 (secondary) and a BF1259 (primary). I want to use Cat filters instead, and want to confirm that I am using the right part numbers.
What is the correct 3406 cat oil and fuel filter number?
There is no charge for this service, but standard message and data rates may apply. 1R-0749 is right on one of the fuel filters. The other fuel filter number 256-8753 looks right also. The oil filter numbers are right. All my trucks have 3406’s.
Can a fleetgard fs-1023 be used for low fuel pressure?
Click to expand… Toss that Cat primary on the frame and use a Fleetgard FS-1023. Using high efficiency Cat filters in both places creates a restriction. Leave the 749 on the engine and try that 1023. You’ll like it.
What happens when your gas gauge is not working?
The gas gauge tells you how much fuel is in your gas tank and alerts you when it’s time to refuel. If your gas gauge is not working, the inaccurate information it provides may cause you to run out of gas unexpectedly.
What happens when an ECM loses ignition power?
If it losing ignition (or key) power the key on/off counter will increase. It helps to further diagnose power problems. Most ECMs have more than one power wire.
Where does the power come from in a cat engine?
A CAT Engine takes three different 12 volt power supply wires to the ECM. 1) keyed from the ignition switch to pin 70, 2) 12 volt battery power to pin 52, 3) 12volt battery power pin 53 Usually pin 52 and 53 are feed power from the battery on one wire that splits before the two pins at the ECM.
Why does my ECM keep blowing out on my truck?
Driver went in pick up the truck it was running fine, after he was hooked to the trailer, truck stalled again, they took him back in the shop and came back telling me that ECM is blown because of corroded wire. my question is, why would truck start at and runs fine for the first time when he just fixed it with fuses and partial power wire to ECM.

Why does my caterpillar 3406b have low power?
One other problem, maybe the timing advance is slipping internally causing the timing to not advance properly. This should be chacked by someone who knows to to check, repair and retime the engine. Having lots of black smoke and high idle is usually a good indicator that you have a leak. Replace the boots you have coming and time the motor.
Is it OK to have low fuel pressure?
Still kinda wonder about new intake valve on pump. But overall, 42-47 lbs at1000 rpm and 38 or better at 2000 no load seems ok when fuel level is high. I mean the obvious is higher tank level, less lift re quired and less air sloshed into fuel- so maybe pump is weak?

How to check the CAC on a caterpillar 3406b?
You want to check the CAC you pressurize it to 35 lbs, start by putting the plug in the right side and pressurizing the system, check the intake manifold, the boots, also the boost guage, and the AFC cover. Plug it at the left side and test the CAC put in 35 lbs air in the right side and read it on the left side.
What’s the problem with my caterpillar 3406b low boost?
My problem is according to the boost gauge it wont get over 15 psi and feels like a 370 detroit in the power dept. just falls on its face once 15 psi is reached. sitting still the engine revs very quick (fastest cat i’ve ever revved) when pulling off it has lots of black smoke just weak as hell.
Can you use high efficiency cat filters on both engines?
Using high efficiency Cat filters in both places creates a restriction. Leave the 749 on the engine and try that 1023. You’ll like it. Ok cool, Ill try that, I know this is going to sound dumb but I have a FF-185 fleet guard on the primary right now that frightliner crossed with that cat 1752949.
