Thomas has been good for me getting work done on #20. Repaired the link end blocks and trued the hanger trunnion and back side. Will be a couple weeks until I get another chance to work, when I will grind the link halves on the side to accept the trunnion without distorting the links.
I suspect that one of the halves on the right side is from another engine since the rear halve is worn more heavily and is still 0.040" thicker than the front half. Noticed the trunnion is from #25.
Grinding the trunnion.
