is it a factory pump with the screw turned all the way up? if so a pump shop told me that it will cut its self back. but yes sending the pump off to have it benched will make a world of diffrence may thing about having a quick rate cam installed to

If you are running a stock flywheel and get your pump turned up to 3000 RPM, practice pulling your legs back real fast if you hear a loud boom coming from the flywheel area. I have seen them cut a tractor in half!

Yes, I have also seen the aftermath of a broken flywheel.In the remining pieces of the flywheel you could see the heat cracks everywhere.For a thirty year old stock flywheel I can see what caused its failure. What makes you think that 3000 rpms is the magic number a diesel engine flywheel will explode. There are tens of thousands diesel engines in trucks spinning over 3000 rpm every day.There should be flywheel shrapnel littering the highways if all diesel flywheels come apart at 3000rpm....

And you think that all trucks have CAST FLYWHEELS? Idiots deserve what they get BUT they usually hurt innocent folks with them

Where are all these thousands of Trucks turning over 3000 rpms? I have been in a helluva lot of different trucks and engine mfg's and have yet to see one spinning that fast. Pickups yes, but not trucks, besides most of those are Automatics, no big flywheel.

Its not the higher RPM that makes flywheels come apart its the heat from slipping the clutch. I've seen one blow in person and several on video and everytime the clutch has not held or been slipped for a longs way out of the hole before it explodes. Steel flywheels look expensive until you see one explode.

I own several trucks (3 Petes and 1 Freightliner currently) You statement of "most are automatics" ...............No not so much.

Its good advice to put a steel flywheel and SFI clutch in

Ran a JD 3000 rpm for 4 yrs with stock style clutch and stock flywheel no issue
Have seen the catastrophic failure you are talking about once
And it was turning closer to 3500 than 3000

Backer,. I meant Pickups with Automatics not Big Trucks. Never driven Big Truck Auto, no desire to either.

the pump was set up on a test bench .I just did not know if it was worth pulling the pump back off to have the governor set for 3000 or not and yes I am running a steel flywheel in farm stock class

definitely. 600 rpm makes a big difference in farm stock. believe me its worth it.
