1975 Viscount Rebuild
The Viscount I have been working on is back from the paint shop and is ready to re-assemble. I've attached a before and after (of essentially the bare frame) to let you see how things progress. Recall this is a frame I decided to salvage because it is essentially a strong chrome moly frame and I need a bike to commute. The components needed a refresh and I have found some sales on last year pieces so it is now time to put things back together.
First issue was the bottom bracket. After some discussion last fall, we decided I had a standard English BB meaning many upgrades would fit. I found a Ultegra triple and an Ultegra BB cheap so why not.... Before the BB would slide through however, I needed to take a die grinder and clean up the inside of the BB tub. When the frame was built the ends of the down tube, etc were allowed to run slightly into the BB tube. For the original BB this didn't cause a problem but the Ultegra require more side clearance so I had to do a little grinding. It took about 10 minutes or so with an air die grinder. Piece of cake.
So with the BB and the head assembly in place, I set out to install the crank arms. This seems rather obvious, line up the slots in the arms to the teeth on the shaft, lub the threads on the retaining cap screws and torque in place. The arms, obviously, are install 180 degrees apart. I am wondering about what appears to be a lock nut. See attached picture. I have set the lock nut and washer on the crank. It appears the flat washer would go in first followed by the lock nut. The nut has an open center and two detents I assume to be used to tighted the nut using a punch or drift. It is aluminum on aluminum so I'm wondering about lubricant as well. Can anyone provide some insight? Thanks.
I may need to come back as I continue through this re-build. I'm going to go slow and ask questions because I don't want to screw it up and have to re-do anything. As always, thanks for your patience and your support.
