How do you prime a 3406b?
The best way to prime is to remove the fuel line that runs from the back of the head where it connects to the housing. Then operate the hand primer. By removing the line you will not have to fight the regulator. Once a good flow of fuel is coming out.
How much fuel pressure should a 3406b have?
cranking fuel pressure is 38-42psi minimum.
Is a 3406B cat a good engine?
Thanks. 3406B one of the best cat engines ever made, should be at least 350 on up to 425hp, a true million mile motor. Not a fan of gmc/white, they can be a little different, although I’ve never had one personally. Have 4 3406B’s and drivers will chose them over a cummins any day.
How much can you turn up a 3406B cat engine?
Could take it to Cat as well. Subject: RE: 3406B more power? You could easily turn it up to 425hp and it be safe. Like you said alot of them came factory at 425 hp and I’ve seen those turned up further as well.
What was the timing of the 3406b injection pump?
Timing has lowered through the years for emissions reasons. The early 3406’s had 26 to 28 degree timing. Along about 1987-88 timing dropped to 18 to 24 degrees, and finally the last 3406B’s had 14-16 degrees.
Why is there no fuel in the injectors?
The tractor in question has not been started for three years. It is quite common for the components of a stood injection pump to seize. Inside the injection pump there is a rack which engages with pinion teeth on the elements, rotating the elements which adjusts the amount of fuel delivered from zero to full depending on the engine requirement.
What kind of advance does a 3406 engine have?
All 3406 engines have variable timing advances. The early (7FB) advances were more prone to problems than the later (4MG) engines. A wore or faulty timing advance will greatly affect performance. You need to look and see what type of advance it has to indeed prove it is a 7FB series.
How does the fuel pump injector system work?
Inside the injection pump there is a rack which engages with pinion teeth on the elements, rotating the elements which adjusts the amount of fuel delivered from zero to full depending on the engine requirement.
