1979 Puch Magnum Project Part 10 - Cranks and Chains

Installing the Pedals onto the Cranks, the Cranks onto the Bike and then sizing and installing the Drive/Pedal chains.
The cranks moved from side to side when I got the bike and had even taken a gouge out of the original ZA50's clutch cover because of it.
I do not know if they had one originally, but I made sure the chain line matched and then made a small spacer from Acetal on my Lathe so stop any side to side play of the crankshaft.
The plastic cog on the original Pedal chain tensioner had worn teeth so I took one from a 10-speed derailleur I had laying around and used new 5mm hardware to attach it.

What's the best way to remove the cotter?

[@n1bpd]

sheldonbrown.com/cotters.html has a variety of different ways. I generally just use a hammer and a pin punch and if that doesn't work I'll use a hydraulic press assuming I'm able to remove the crank.

[@durrellwilliams39]

How did you get the right side off ??

[@n1bpd]

I think I ended up cutting it off with a grinder.

[@maxmoreirabhmg5896]
