Well i've got my truck back together with new main/rod bearings, clutch, harmonic balancer, and some other stuff. Now it might just be that i'm looking for anything to go wrong but if I bring the idle up slowly in neutral there is a little vibration through the whole truck. Once it is above about 1500rpms it smooths out. Its almost like one injector isn't working at idle/low rpms. The injectors are brand new 190's.

It could be that this vibration has always been there and its been so long since i've driven the truck that I just never noticed. I just don't know. What do you guys think? Should I be worried?

Thanks, Aaron

 

Where did you get the 190's? They may not be balanced real well.

How does it run under load?

 

The 190's came from Piers so they better be balanced perfect.

Runs perfect under load.

 

I wouldn't sweat it. I noticed after the 3200 RPM spring that sort of a shimmy was there on mine too. Load it and it smooths right out. I think it's the governor surging a little.

 

Is it possible the clutch pressure plate assembly isn't the way it came out (original position)? And if you replaced it, is it truly in balance? I've had new assemblies that combined, weren't.
