A few pointers on the chain rails.

1) On the 117 engine all long tails go down. Not sure on the 116 engine.

2) For the 117 engine the inner rail for the left is the same as the inner rail for the right (Long). On the 117 engine the short rail gose on the outer left head. I belive the 116 engine has all the same rails. You better check.

3) The left head outer rail is dificult to hold and I was afraid of droping it. Installation of this short rail can be done safely using a thin welding wire running through the lower hole. With the upper pin in place the welding wire can be pulled out and the lower pin can be installed. See photo.

The reason I was half done when I started this job is that I originally put the 2 long rails on the left head and figured it out when I got to the right head. They do fit but this is wrong.
