There are 32 spiral locks on the piston pins. It takes me about 20 min. to put in four (4), or one piston. The first one took over an hour because I put the rod on backwards. I spent 15-20 minutes . trying to figure out how the piston on #1 cylinder should be oriented. then I precoded to put the rod on wrong. Those spiral locks are twice as hard to get off as they are to put on. I have completed two and 1/2 pistons so far.
I did not have any trouble with the crank. It slipped right in and rotates with ease. I even remembered to put the two piece seal in this time!
Tomorrow I will complete the pistons and determine what head gasket I need. I have not file fitted the rings yet. Another time consuming job.
