Earlier tonight I got ready to install the flywheel and clutch. First the breathers needed to be installed. The lower breather bolt got new copper crush washers and the upper got a new gasket.
Everything had been cleaned up prior and I used the SD Tech clutch kit with new friction discs and intermediate plate and transmission gear. These use a 4mm spline rather than a 2mm spline as the original was, so they are much more durable.
First pick a cylinder and put it at TDC. There is an arrow on the flywheel that aligns with the TDC casting on the crankcase, doesn’t matter which side. This is important for later, the arrow isn’t lined up in the pic but it was adjusted for the important bit.
Install the flywheel with some blue loctite on the bolts and fold over the bendy tabs.
Springs next.
Followed by the pressure plate, this part has a dot on one of the splines that must be aligned with the arrow on the flywheel so that the springs seat properly with the reliefs in the back of the pressure plate.
Joe let me borrow his flywheel locking tool and homemade clutch alignment and assembly tool which is basically just a 4mm splined gear from a transmission output and a long bolt that threads into the crank, along with some spacers. Tighten it down and the pressure plate compresses the springs so the clutch can be assembled.
I forgot to take pics of the next step but the first friction disc goes in, then intermediate plate, then second friction disc, followed by the starter ring gear which holds everything together. Torqued down and now we have a new clutch assembly ready to roll.
