.0030 is three thousandths. .030 is thirty. Do you mean thirty? That sounds like a lot of runout.

THREE thousandths...My bad. ( Thats what I get for watching the Colts come back at the same time!)

 

I am frankly surprised that your oil pumps haven't self destructed at run out numbers that severe.

 

you are right I mean .0045 and .0040

 

That's OK, we've all got the "Typos" goin' on tonight!

 

You know I am not 1 to bash the moco but you would think they would have tighter specs from the factory and send the new bikes out with gear drive that would eliminate a ton of the current down falls I know it would probably have some new fall out but seems like they would be better built as much as we pay for them.

 

When they were trying to refine the TwinCam they ran the forged crank with Timken bearing. That required shimming each crankshaft prior to install. That was expensive, but bulletproof. So they started cutting corners and the Timken Lefty bearing was replaced by a cheap slap together roller bearing in '03 followed by cast cranks in '05. When they stroked the motor in '07 (96") they lost all control of runout tolerance so they changed the spec instead of fixing the problem. You can't run gear drives that loose.

If they did fix the problem, you still couldn't run gear drives because of the additional noise ( for EPA purposes,) or so I'm told. My gear drives are silent going down the road but do "tick" at idle.

 

and if they was still bullet proof they wouldnt sell as many parts or bikes ah well nothing can be perfect.

 

It does not matter what year crank you have if it is a 99 dyna or a 2000 up anything else the crank is pressed together and can slip. I am glad some of these people think they have a better crank in certain year bike but they all will twist. I got .007 run out with the cam plate off and .003 with it in place. You know i don't think any harley on the road will run with out the cam plate in place. Oh ya i will let you all know when my .007 give me some trouble plan on going way over a 100,000 no problems. You probably want see much over .003 with the cam plate installed and like i said your bike will not go down the road with out one so if .003 is what the want to run gear drive my .007 W/O came plate and .003 W/cam plate will be just fine. Oh and cams running in aluminium has been going on for ever in metric cars and bikes and all the Triton V-8's and V-10's Fords the cams are running in aluminium and go way over 100,00 miles. Rule 1 believe 1/2 of what you see and NONE of what you hear unless you have plenty of money to waist. I like to keep my money in my pocket and not give it to people that tell me what i need i know what i need.

 

Well, I wouldn't mess with geardrive on a 96/103. The newer Hyd chain setup works fine for 95/99% of street motors. Check the shoes every 40k or so and go. Take that money and have the heads done or get a proper tuner+tune. On my '09 the crank was at .003 but I never even considered gears. I checked it to see I needed to have the crank trued/welded. I think somewhere around .0035-.004 or 110+hp would be my call on that to save the oil pump/cam plate?
