Crankshaft runout for '09

[Josey Wales]

There were some posts here and another forum about the possibility of the moco fixing the flywheels and adding a timken bearing. Well here is what they did do!

Left side flywheel – Shallower counter bore

Change to ALL Flywheels
END PLAY SPECIFICATION
.003” - .013”Starting in 09MY the flywheel will be able to
use either the long or short bolt. Long bolts will
be used up in production before the short bolt
becomes common for both. New flywheels will
retrofit.

There you have it, The Great fix.....Increased Runout specs that should fix it!

anyone suprised?

Unbelievable.

And people think the new Indian Motorcycle company isn't going to make it.

When I did my geardrive cams on my 04 Ultra 1550 I had crank runout of .004. It was beyond original spec but IMO the .003 was unrealistic anyway. 40k miles later, no problems and perfect oil pressure.

That is pretty good. I had .0033 runout and we couldn't make it fit, even with the undersize pinion gear. a gear drive takes much tighter tolerance than a chain drive and if the crank has a problem(a small shift) the gear drive units won't work and the chain might. I don't have problens with oil pressure or oil puking either, but I had to stay with the original chain drive system as the new system wasn't being retrofitted at the time.

andrews says .004 maximum for gear drive. its easy to get away with more runout with the new hydraulic tensioners. INITIALLY. you will still whip out the oil pump, more runout, quicker the pump goes.

And its suppose to retrofit? Just because they upped the specs doesnt mean they will see that spec.Putting the spec in print kinda covers their butts esp with early builds.Hd seemed to answer most complaints owners of older models had this yr.Again its up to you to open the checkbook.

End play has nothing to do with runout. The .003 is good, but the .013 is getting sloppy. Should be capped at .010 max in a real world. End play is the amount the shaft will go side to side and is completely seperate from shaft or pinion runouts.
Last year it was .012 which is a disaster in the making and only a matter of time for pump destruction. Personally I have .007 on the sprocket, but don't know about the pinion side and don't care any more. Mo Co in my view really look like fools coming up with a .012 runout figure.

Where is the 09 shallower counter bore area that has changed with the bottom end setup this yr?

motor sprocket side. but they say they will use all the existing longer bolts before they use shorter bolts in production. got that? wuts it mean? anyone have a problem with sprocket shaft bolts shearing?


nope!!!!!!!!!!!!!problenm is on the other side of the motor HD!!!!!!! dumbfux.

[rbabos]

How true

[pittguy]

Havent heard of many bolts shearing either,could see that the depth of counterbore may be a factor of shaft end wobble on that side of engine.
