One item that used to perplex me was reinstalling the K-FLEX   form the new thicker rotorbrake (R/B) disc up front, it became a little tighter getting the shaft to drop in.


However, when Bell increased the size of the transmission         persuasion. That was until a fellow wrench, Kevin H., showed me the light.

Second, do not install the R/B disc on the free wheel unit 

Cradle the R/B disc in one hand, lifting it up toward the engine compressor housing. The important thing is to position the top  

Jiggle the disc around while repeatedly stabbing the engine side of the shaft and lowering the transmission side. Sometimes engine oil lines, especially the #1 bearing scavenge line, will limit the vertical height you can lift the disc.
