Yes posted this on multiple forums.

I dropped off the pump on monday at a shop in town. I talked to them on wednesday and they gave me the bad news. Pump was seized and full of metal filings. So they are building me a new one.

That's never nice to see. You gonna get a stock rebuild or get a gov spring n fuel pin installed?

SaskW200 10-07-2011 10:20 PM

Well it will be "stock" with a M&H M2 pin, timing spacer and 4200 RPM spring.

Don't you think your going a little overkill on the RPM's? Just so you know anything over 3600RPM's on a cummins you need #60 valve springs or your valves will start to float.

I put a lot of thought into that.

I choose the 4200 spring for a couple of reasons

I only wanted to go into the pump once. I figured buy going that high no mater what I did in the future I wouldn't have to change the spring again.

I have read in several sources that the VE will not fuel the motor much past the 3500 point. So really once you go past that 4200 or 10000 rpm spring whats it matter?

I have never had any problem over reving my gas engine trucks and they don't have a rev limiter. So I fell confident with the tach I won't wind this motor to the moon.

If I could have found a good reliable and proven way to defeat the rev limiter portion of the governor altogether I would have.

I'm really looking forward to the new pump. I was never impressed with the millage of the truck or the power. It seemed weaker than my last cummins.

LOL thats to funny never over rev'ed your gas engine. You have a lot to learn if you think a diesel is anything like a gas engine :argh: And if you think it won't fuel above 3500 you are WRONG
