1980 B2 Rebuild

Was able to get the water pump drive shaft removed with some lock jaw pliers. A bit of stripping from the wrench but otherwise in good condition.

Moving on the the drive shaft, I can't seem to figure out how to get the bolts removed on the engine side with the boot in the way. Any suggestions here, as I don't see anything for this in the manual?

I can remember it being a bit of a challenge. The boot tends to get hard and not very pliable which adds to the issue. I found that wiping the boot with wintergreen oil will soften up the boot which is a good thing.Let the wintergreen oil work on the boot for a day before  reafing on it or you'll likely split it. I fixed up 3 splits in my boot with Loctite Black Max, which is a superglue used in fabricating custom o-rings.  Also, as I remember it, if you remove both bands, you can slip the engine side more inbound towards the crankcase giving a bit more room to work on the bolts.. I found that a block of wood across the swingarm and between the spokes of the wheel was needed to hold the driveshaft while breaking free the 4 coupling bolts. They're torqued to 54 lbs/ft plus likely blue locktite.
