This sucks!!! Thispast weekend I was dropping in a set on 255 cams in my 07 ultra. While in thereI went ahead and checked the run out on the crankshaft. I didn’t expect it tobe perfect but to my surprise it was 0.028. I didn’t believe it at first so Isetup the dial indicator differently and tried it again and got the samereading. The motor only has 29,000 miles and before this cam change it wasbasically a stock motor except for a stage 1.

The funny thing is its not vibrating excessively and notsumping oil. I inspected the oil pump and brass bushing and they are notshowing any wear. It looks like there is some wear on the end of the crank, butit’s very very minimal.
Being I don’t have the time or money right now to pull thecrank and have it reconditioned I put everything back together and decided torun it like it is for now. I will pay close attention for an increase invibration, a loss of oil pressure and watch for sumping.
Hopefully it makes itthrough this summer and I can tear it down and have it reconditioned nextwinter. I will open it up half way thru summer and inspect everything and recheckthe run out to see if it gets worse. Has anyone else continued to use theirbike with this much run out?

 

.028 and no visible wear on cam plate bushing or oil pump gerotors. . .? That seems suspect I'd want to verify with another caliper. My .006 runout at 16k miles had chewed into one of the oil pump gerotors enough to warrant replacing.

 

Watch this.

Patroit HD of Fairfax, VA Built my 103 motor using a stroker crank that had. 019 runout. At about 35K on the motor the head gasket blew and I took it to an indy to fix. He discovered the runout problem along with the destroyed oil pump, cam bearings, cam faces and everything else. The Patriot Service rep told me it was probably because I didn't service the bike properly.

 

Check your gauge...

Make sure it isn't metric...
0.028mm = 0.0011"

 

That's their go-to excuse for everything. The bike could be brand new off the floor and they would say its your fault.

the only reason theyre still in business is because they service all the rich yuppies in fairfax and loudoun and are a meeting place for Rolling Thunder

and like def_mute said, check to make sure the reading was in inches and not milimeters

 

It's my understanding that the MOCO says up to 0.012 is acceptable (which I think is B.S) so 0.028 sounds way out there.

 

does anyone in here actually know what .012 looks and feels like?

Is it acceptable, ***** no. Thats a **** poor excuse to not have good QC

Question is, what does that .012 runout do under crank pressure?. It gets checked under normal revolution's not when be loaded with cylinder pressure and explosion, coupled with possibility of detonation, primary chain slack and other driveline load.

 

I would check your gauge.

 

Exactly! I see a lot guys here putting gear drives in and I often wonder if they even checked the run out on the shaft or have any idea what they are setting themselves up for down the road? Max run out for a set of gear drives should be no more than 0.003" (if memory serves) and I'll bet ya a dollar to a doughnut not very many fall into that tolerance.
