It's apart, using Novak rebuild kit with Advance Adapter SYE sourced from Tom Wood. Borg Warner chain has been decreased in gas, sprayed off with brake cleaner and dried. I'm now soaking the chain in ATF fortified with high zinc engine assembly lube in a pan over kerosene heater. Purpose us to drive out air bubbles and have the zinc-rich ATF deep into the chain. I did this to engine timing chain, figured can't be a bad idea for any chain even though the xfwr case us way slower.
Figuring to notch outer race edges in two places 180-deg apart, fit this slice of mower blade to insert and rotate, and weld to a bolt that fits my slide puller.
