Digging into the Guzzi part III

Thanks to some found money, I opted out of fabricating my own special tools for the V700 and instead purchased some from MG Cycle. The flywheel/ring gear holder will obviously lock everything up to allow removal of the generator drive pulley, timing gears, and then ring gear, clutch, and flywheel removal. The other tool pulls the rear bearing carrier.

In action, using the 3-tooth part to hold the ring gear for the starter. The single tooth on the top is used later on, after the ring gear is removed, to hold the flywheel in place.

This pisses me off to no end. As mentioned previously, this bike had a lot of work done to it in the 70's. Apparently besides new cylinders, pistons, and a top end job, they also put in brand new clutch plates. What I don't get is, why the hell you wouldn't replace the transmission input seal while everything was apart. Because they didn't take that step, these brand new clutch parts are completely ruined by gear oil. Such an expensive waste...

Timing gears. You can just make out the scant timing markings between the cam gear (big) and the crank gear (small). These were wiping off when I put my finder on the gears, so I had to make my own new markings that were more obvious.

Took some white out for the time being, need to clean it up a little on the cam side, but it'd be hard to mess up alignment for timing now.

And this is where my work ended for today. Shockingly, I don't have a 26mm socket or box end wrench anywhere (in fact what I have goes up to 24mm, then skips to 27mm and up, so timing gear removal, and subsequent bottom end disassembly, will have to wait for another day.
