darrenjlobb's Rolling Road Chassis Dyno Project

Mini update,

Got a load of parts together, various bearings, springs, spring cups, rubber bellows and ceramic faces:



Got the center cartridges back together today.

Started by fitting new bearings to the main shaft to test before packing with grease:



But after fitting found the new bearings I had were to wide on the shoulder, and meant the shaft didnt protrude quite the same which would have caused issues with rotor / stator clearance down the line.

To tore it apart again and raided the local bearing store for some, and finally found exactly what I was after:



So packed the tube with grease and fitted the shaft / locking collar, and then began work on the ceramic seal. After my international search I gave up trying to find a replacement, so went about changing it to accept a modern seal. which has involved basically using loads of parts from different seals (hence so many boxs) to make one that works, along with machining down the oem collar.

First step is to fit the stationary ring in the housing:



And then fit the bellows, mating face, spring, seat and modified collar:



And the two center cartridges all together / ready to accept the statr housings, which I'm still working on:
