Re: rotor reverse threaded? 1975 860GT

Yeah, I got the first one out by punching from the backside into the small hole, and it eventually came out, but the second one refused, so I drilled and dremeled it out. used about 6 pin punches and one Dremel tungsten carbide cutter. Phew! Judging by the 860GT parts manual, the crankshaft gear, fl...

Re: rotor reverse threaded? 1975 860GT

Finally had to resort to drilling and Dremeling the last stubborn pin out.
Even though the parts manual shows it as a pin, it seems like it is welded in.
Biggest challenge will be to grind enough out to maintain a fairly good balance on the gear.

Anyone else had this issue?

Re: rotor reverse threaded? 1975 860GT

Yeah, no surprise at that. The hex holes in the heads were damaged, either from the factory or by the dealer that replaced a bad stator many years ago. I was able to get the durned things loose by pushing hard on the hex wrench whilst applying brute force counter-clockwise. I consider myself lucky (...

Re: rotor reverse threaded? 1975 860GT

Thanks for the reply; after further review, I found three replacement screws in the Sachse ignition kit, and had I had any forethought I would have found them, and seen that they are "regular" threads. Getting new ones with the kit is great, as the original ones are seriously "hogged" to where the h...

rotor reverse threaded? 1975 860GT

After getting the ignition rotor/gear assembly off of the crankshaft, it appears that the six flat head hex screws holding the assembly together are revers threaded, looking from the backside; not easy to tell.

Anyone been here?

Thanks in advance.

Regards,
Richard

Fork stop repair

1975 Ducati 860GT: One fork stop "pin" is bent from the one time I dropped the bike. Question: any recommendations, short of welding to repair to a normal height, so the fork assembly no longer contacts the fuel tank? Any advice is appreciated. Thanks in advance.

Clutch nut removal

I have been unsuccessful in trying to loosen the clutch nut, 1975 860GT, as spragging and trying to hold the clutch basket from spinning is beyond my limited intelligence. Washer is straightened up, impact driver has not helped, having trouble holding the basket and spur gear from spinning; any grea...

860GT stator alignment

Hi All, Another semi-ignorant question: On the alternator stator mounting on the case, do the triangular tabs, when installed snug against the shoulder of the stator assembly, give the stator proper alignment and clearance to the rotor, so as to not be rubbed by the rotor when re-mounted on the case...

Hi Steve,

Thanks kindly for the info.

One question still remains:

Shallow or deep dimples on the rims?

Re: 860GT headlamp relay

Thanks for the reply. To update matters, I am rewiring the bike with new wire and connectors, and adding relays for all circuits (to get the big current out of the switches, and into relay contacts), and am replacing the standard Early 1975 Ducati ignition with a Sachse unit. Given that, the kill ci...
