I finally got some wrench time this afternoon. I had pulled the shroud off of the engine last night. It's cracked all along the head :doah: I put up an ad, but if anyone has a 1970 Shroud, I could certainly use it.
The flywheel was really stuck. Most of the time, you can get them off by tapping the shaft with a block of wood. I ended up putting a puller on it and even then it still wouldn't budge. The impact gun got it off of there though. I was really afraid it was going to crack the flywheel, but after soaking for 16 hours, if it wasn't going to come off, then there wasn't much I could do about it.
This is what I found.
The engine wasn't producing a spark and I'm pretty sure it was the corrosion on the points. Oddly enough, everything inside the housing was really clean, but I had already picked up a new set of points, a condenser and a coil. I swapped them all out and set the points. While I had the stator off, I cleaned the old paint and grime off the block.
Once I got that done, I started on the other side. I still hadn't removed the TC driver. I was dreading it because the last time I tried pulling one of these it snapped in half. After some careful soaking and removal of the other pieces, the rear driver half just slid right off. I danced for a few minutes to celebrate. Then I realized it didn't matter and I needed a new rear half anyway. Apparently, this bike was ridden A LOT. The previous owner(s) wore the rear plate all the way through to the back bracing. I would never have believed it if I hadn't seen it myself. So, it looks like I'll be on the hunt for that part. The rest of the driven looks like it's in surprisingly good shape with little to no wear or corrosion.
Another thing I noticed -- there are hairline fissures all over the crank case cover. I'm hoping they don't go through, and it doesn't appear they do. Are they defects from the cast?
I attempted to remove the crank case cover, but it's not budging. I got it gapped about 1/8" and it stopped. I have a feeling it's just binding up. I might put a puller on it and give it a hand-tighten turn and see if that helps.
Hopefully, I'll have this thing done this time tomorrow. I've never worked on an engine's internals before, so this should be an adventure to say the least. I did pick up a new piston, rings, seals and gaskets. After looking at the valves, I might order a set of those as well. They looked pretty rough.
