Crankshaft of M900

[Dmitry]

Hi forum! My Ducati Monster 900 is 1997 year. What crankshaft suitable for my Monster? Only 1997 year?
Thanks!

1992 up to 1997 will be a single phase alternator (same as yours).  1998 & later had a 3 phase alternator and therefore a different crankshaft.

Look at the photos please:


The first photo is my crankshaft. This crankshaft suitable for 1993 up to 1997 year inclusively.
And the second photo is crankshaft for 1998 & later.
I am right?

All I can say for sure is there is a difference between 3 phase crankshafts and single phase crankshafts.

your crankshaft part number 14620351A, 1997 monster 900.

looking at the parts fiche http://www.millwaysparesonline.com.au/partFinder/fiche/85726 this looks like your image, with the longer skinny section on the right side.

the 98+ part number 14610511A, your 2nd pic looks to match the parts fiche, with a shorter thicker taper. http://www.millwaysparesonline.com.au/partFinder/fiche/87012

hope this helps

you just know when my alternator is a two or three son, after it is very easy to know.

There are 'long' and 'short' versions of the single phase cranks.

More details here, about halfway down in the 'notes':

there are in fact two types of crankshaft, the short that was fitted on the 900 to 92 and then up the long end 97 with two alternator son.

Probably to accommodate the early 300W and later 350W single phase alternators?
