Stator removal

[bdfinally]

Installing a new stator on a '00 M750 dark and am working from a scanned M750 shop manual that states

use puller 88713.1332 to take off the  inner  ring of  the bearing  (A)  from
the crankshaft and  fit  it  into  the
cover.

When I pulled the cover off the stator stayed w/cover and no "ring" was left on the crankshaft.



the only thing I see is a circlip holding bearings in place



am I missing something and how does that stator look to you guys?

As always thanks in advance.

Dunno WTF they were talking about with the inner ring.

Perhaps early bikes had an angular-contact bearing in the cover.
That'd be a really wacky thing to do.

Stator looks OK, but visual inspection of an electrical device isn't so reliable.

What AC voltages were you getting?

barely moves when I rev it up from whatever the battery contains after I charge it up. I installed a new R/R  last November and have had problems keeping it charged since. Thought maybe is was crappy connections, but I've tried several different ones and still the same, ride it for a few short trips and then not enough juice to turn it over. Anyway bit the bullet a bought a new Electrosport stator.

Anyone know offhand the torque specs for the stator bolts? Haynes say 8 to 10, but that seems awfully high.

When you measure stator output (AC) what are the numbers?  With the regulator disconnected, connect an AC colt meter (on a scale that will read over 70 volts) between two of the three stator wires.  Rev engine to 3K RPM.  Record reading.  Now take one of your leads and attach it to the third wire.  Record reading.

Without putting the bike together you can measure for winding opens or shorts.  With an ohmmeter measure resistance between the stator wires.  I don't know of an official Ducati spec, but a common spec is .5-2 ohms with little variation.  Now measure from each stator wire to a clean part of the engine case..  You should have more than 100 ohms.

Thanks Speeddog & Howie for suggestions and guidance.

Spent the week making sure every connection in the electrical system was good to go and a new battery to boot. Voltage at the battery never increased when running. This morning checked the new stator output and it increased as I revved her up (no tach) across all three yellow wires the same. Did a diode test  and R/R failed. Got readings outside the norm or readings that shouldn't have been at all. Anyone have a known issue with this one, http://www.electrosport.com/street-bikes/ducati/m750-monster-2/regulatorrectifier-605.html. Again it's a '00 M750 dark.

My two bad experiences with Electrosport are merely two data points, and not a trend, but I will never buy anything from them again. My opinion is they have good customer service, and marginal products.

Funny you should say that. The stator I just bought was off an ebay merchant and the seller had Electrosport drop ship it. Someone screwed the pooch and sent it to Kentucky to be shipped overseas. I have to give them credit tho, when the mistake was pointed out they got right on it and shipped another 2nd day across the country.

Installed a new R/R yesterday and output @ battery is 13.9 to just over 14 DCV revved up. Is that within tolerances? Thanks in advance

[Howie]

Yes.

Great, thanks Howie. Mobile just in time to see Jake Johnson take it to 'em down the road tomorrow!
