...I have read through most of this and have a couple of suggestions.
1. The 'Shift-Box' (at the ZF) Should Never be DRY!! The Fact is, ALL Sliding/Moving Assemblies should be PACKED with Grease. Especially the 'Ball' Joint! The Box should practically be Near Filled with grease. All Metal to Metal contact Must have Lubrication. In the case of the 'Dry Box', after a good greasing, a Much Smoother, Easier Shifting will be Realized. Plus, the Parts will wear slower.
2. To remove a Steel Needle Bearing from it's Carrier...provided the Plan is to Never re-use the Bearing Again! First clean all grease out with a solvent. Clean solvent out and dry. With a Torch heat the Outer Race of the Bearing, And ONLY the Bearing. You are NOT trying to Expand the Carrier, You want to Heat the Bearing to Expand it! Since the Thermal Dynamics of Steel, dictate "Contraction Is Greater than Expansion", after letting the assembly Air-Cool, the Bearing can be pulled out easily. It may even Fall Out. We do this Every Day at the LFW Machine Shop. Heating the Carrier to Expand it, may Not work...as Both Bearing and Carrier, are Expanding at the same Rate.
3. One does NOT, just change-Over and re-use a Flywheel, from One Engine to Another. Flywheels Must be Re-Balanced ALONG with ALL of the 'Rotating Assembly'...Even the Bearings are Included in a Professional Balancing. Just Bolt it On a New Engine...You'll wonder Why the Rearview Mirror Vibrates!
For What it's Worth,
