Now what?

[Tinker]

The next issue is sprag clutch seems to be on its way out. Twice today the starter has span up without turning over the motor. Does anyone know a generic part number for one? Thanks

The exploded view in the workshop manual only shows & states a 'complete clutch'.
The code is M1614030. No 9 on the list.
Maybe a start in the right direction?

It is item 20 freewheel that I think is the issue

I have not had a chance to have a proper look but it could be using a similar cam shaped roller bearing as Ducati, that only grip one way and slips the other. When I have had problems with Ducatis I have always shortened the spring which works every time, just guessing here, if anyone knows better, I would be interested to know.

[Tinker]

Ah cool i did see a video when someone did the same and shortened the spring. But I want to make sure it’s ok. I have ordered a flywheel puller. Has anyone got a sketch of the tool to hold the generator rotor flywheel thingy?

[ogr1]

According to the manual....

[Tinker]

Thanks I have bought one of those it’s the other bit that goes inside the rotor to hold it while loosening or tightening the securing bolt

Hi Tinker,

You can find a picture of the original tool in the parts' list M00100006400. Here are two pictures of a homemade version.

Great thank you Robert do you have the rough dimensions? I will get one made

Hi Tinker,

I am currently travelling and can only send them when I'll be back home on Thursday. The former importer März in Germany sells the original tool for about Euro70, but I don"t know whether they ship to the UK.

Regards
Robert

Thanks Robert that is awesome I will get the welder out!

No problem. A piece of plastic tube (see photo) between tool and flywheel centers the tool and helps to overcome magnetic attraction
