What is the function of governor in fuel injection pump?
The governor maintains all speeds automatically including idling and minimum speed. Governors are often included in the design of the fuel injection pump.
How much can you turn up a 3406B?
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 is pump governor?
A governor is a system that is used to maintain the mean speed of an engine, within certain limits, under fluctuating load conditions. It does this by regulating and controlling the amount of fuel supplied to the engine.
How does the governor control speed?
To control engine speed, a mechanical governor uses gears and flyweights inside the crankcase to detect changes in the load and adjusts the throttle accordingly.
Is the 3406B a good engine?
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 many thermostats does a 3406B cat have?
190 thermostats are common and 205 fan switches… so it’s going to creep up there until the fan gets under way. My N14 runs about the same range. I forgot to mention he did the thermostat already, cleaned up the housing (removed the corrosion, but might not have been the thing to do vs.

How do you adjust a Briggs governor?
First, loosen the arm until it is moving freely. Next, open the throttle to full capacity while making a note of which direction the arm moves in when the throttle moves through it. Once the throttle is fully opened, move the governor shaft in the same direction the governor arm traveled.
What happened to the cat 3406b?
Around 1991 Cat changed the injection pumps and went to bigger cam bearings and plungers. This can be noticed by 7E-5888 cast in the housing, while 3406B pumps had 7W-3906 cast in the pump. Timing also dropped to 9.5-11 degrees on the later pumps.
How many degrees of timing on a 3406?
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. Look for the serial number on the block of the engine. It should be either 7FB or 4MG prefix.
