crownwheel to pinion setup

Stuart makes a good point- the 1 1/8" bore  roller bearing CRL 9 is 1/8" narrower than the  1" bore ball bearing RMS 8.

Check the pair of angular contacts have narrow outer rings and are mounted back to back with the outer rings touching.

A browse through several threads may prove useful although will introduce red herrings

The term banjo is often used. I am only familiar with the later 2 piece and torque tube assemblies. I presume the term refers to the central drum of 4 piece assemblies although it seems barely related?

Hoping to have time tomorrow to strip them out and inspect

I agree, I looked through some and I felt like I was developing more questions than answers.  I'll keep going with it and hopefully come with a few definitive comments to post once we get it all sorted.
