This is a source here in the US, likely very impractical for you, but it's got some info.

OEM gear puller and spanner socket.

Notice the very robust construction.
I leave the nut on the end of the crank, backed off a couple turns, to keep the puller and gear on the motor when the gear comes off the taper with a bang.
I paid a lot for that puller and don't want to get a ding in it when it leaps off and breaks my foot.

Thanks, Speeddog.

My buddy has one of those pullers, equally sturdy :-)

I´ll have to organize the socket, or maybe I´ll bring the whole motor to the nearest Ducati dealer. I don´t expect I´ll be needng the socket more than once ....

I've used that socket once, for sure, maybe twice.  Undecided

Puller looks overbuilt until seen in action.

Hello, all.

Today is uncacteristically a nice day here, so biking almost looks like an attractive activity ..... but quite a lot of work remains until the m80o will go anywhere. I got the cylinder heads and valves back from valve seat work the other fay, so they will going back together soon.

I still do not have a clutch, though. My buddy went to a dealer to get some motors he´d bought for parts, and I asked him to check for a 750 clutch. Due to me beeing rather unspecific, and my buddy beeing a bit over-enthusiastic, he came back with a scrap 750 motor as well. Unfortunately the old one with the releas mechnism in the cluct cover ....

I´ve tken it apart anyway in order to see if anything could be used, and it might possibly --- I gave up any activities when I found the drive ratio of the 750 is 31/62, a opposed to the m800´s 33/61. I do not want a clutch making the engne spin faster at a given speed.

I do not know the specifics of various clutches, and LArs has menioned several that will fit on the m800 motor. However, if I specify what I´m looking for as follows:

 ¤ No fancy spring damper arrangements;
 ¤ No slip / lock-up function (which I think the newer wet clutches have);
 ¤ 33/61 ratio

What would you recommend me to look for, provided there is something that fits these requirements?
If there isn´t, what´s the next best alternative?

I don´t know this kind of things, and looking into Duc spare parts lists is not much help. So I´m putting my faith in this forums knowledgeable members :-)

There seems to be 3 versions of the 'regular' clutch basket.

Appears that they all use the same plate set and hub.

You'll have to plow through this and cross reference to confirm.

This information source is ~99% reliable.

Each year and model owners manual will confirm the 33/61 gearing, so best to check that as well.

Sorry for the formatting and frequency of the word 'clutch'.

Speedog,
fantastic, thank you waytogo

I´ll go through this, should really help.

How important do you think a matched set of clutch/ primary gears is? I´ve been looking in ebay, a lot of clutch baskets but often without the crank gear.

Kind regards,
Torbjörn.

You’re going to really want to get a matched set.  A mis-matched set will work, but could start howling later on.  Generally, it’s always best practice to get a matched set.

I´ll see what I can find on ebay, hopefully I can find a complete set-up (and hope the potential seller ic an honest person ...).

Many years ago when I lived in Germany, I saw an ad for Yam XS650 parts. I went to see the guy, and he had lots of XS650 parts ..... all sorted in bins and shelves, all crankcase uppers in one shelf, the lowers in another, all  input shaft 1st gears in one bin, all the output shaft gears in another, and so on ..... it was like a goldmine, only it was not real gold.

Anyway, in order to run the motor without the cyl base gaskets, I had to machine the squish bands on the pistons:

20200121_213126 by torbjörn bergström, on Flickr

The squish area in the heads is at about 8° relstive the gasket surface, so I machined the pistons at 6.5° to 7° in order to not get a squish area that opens towards the cylinder wall. I just measured the vertical cylinder, and the clearance is 0.9mm at the piston edge, and 1.1 mm 9 mm in on the piston. I think I can get away with that.
II just hope the othe piston will be in the same area, both started at 1.2 mm with the 0.4 mm base gasket.

I´ll check compression once I have the heads assembled.

Hello, all.

I just bought a clutch unseen on the proision I could give it back if it was not what I was looking for (no-frills, no springs etc). I just took it from the box it came in:

20200221_180250 by torbjörn bergström, on Flickr

Presumably, with all tht stuff in the centre, it is the slip/grip clutch (don´t remember Ducatis acronym for it)?

If so, I´ll give it back, I want this to be as simple as possible.

Kind regards, and a nice weekend to all :-)
