starter sprag bearing

[GONZALO]

Hello eveybody
Ca anyone help me?
I need to know if the the starter sprag bearing (free weel or ruota libera) of the PASO 750 it´s the same of PASO engines 906.
I know that PANTAH, PASO 750, and bevels fits the same, part 0799.50.195. BUT, is it the same in 906?

Hi Gonzalo,
When I had the 906, the free wheel broken.
I can't remember its number, but I don't think it's the same of 750.
The 906's engine is very different by the 750 and very similar to the 907 one.
The 907's free wheel has the number 70140011A.
I think it would be the same of 906, but I can't be sure.
Good luck.

Gonzalo,

There is a Tech FAQ in the 750 forum at the top of the page. In the FAQ there is a discussion on how to fix the sprag with a spring. Take a look at this before buying a new part.

I have seen 2 different modells, but cant help with numbers...

the 906 Paso, 900ss, Pantah engine starter sprag clutch is the same as an LC4 Freewheel bearing (KTM Part No.58440026000), avaliable from your local KTM dealer. I just fitted one of these to my 906 Paso. It is identical to the original ducati part and it cost less than half the price.

In my ST4S free clutch went broken(year ago) and i bought KTM part(cant remember now ordering number), but i had to use ONLY those "friction pieces"(and spring) from new KTM OEM part, cause they "holder"(frame) was different, but that is only in my ST4S. Remembering, that KTM part will fit to older modell Ducatis, but not "direct" to newer modells. Anyway my "friction pieces" went too bad condition and also that spring was totally too loose, so KTM part helped me enough... Ps. remembering, that KTM part was something about 60€....

i have read since posting the original article that instead of replacing the bearing, simply shortening the spring may work. unscrew the spring apart, cut about 25mm off the tail of it (the thick end) screw it back together, and refit it (don't try to pull the ends apart or you will loose the tension on the spring). oh well... i'll just have to wait until this one fails, then give that a try.

Shortening spring work. Think I shortened mine like 3 times, like 40-50mm in total.
I also machined the little knobs the spring holds together to make them smoother after wear.
I`m replacing it know after 130 000 km`s. But still works on my Monster!

Regarding interchangeability, a 600 freewheel don`t fit a 900.

Cut off thin end, not thick end as this is where you screw thin end into.

if you cut off the thin end (tapered end), both ends of the spring will be thick, and you will be left with nothing to screw in with.

My wrong. Youre right, has been several years since i did this and forgot exactly how it was set up.
