and installed it in the 123 housing with the 3.69 ring and pinion. Just a test fit, but preliminary measurements suggest it will fit just fine. After taking it all apart we were looking at how the carrier is shimmed in the housing to get perfect meshing on the pinion bearing and my favorite machinist said Viola' or words to that effect and measured the rather large circlips the hold the bearings in the housing and said "these circlips are used to center it....they are different thicknesses." ....and so we measured the ones from the 123 rear and they were 54 and 62 (thousands?) and the ones from the 190 diff were 56 and 60....so both pairs added up to 106. He said ......"they must have pairs of these and pick them in varying thicknesses to center the carrier."

So after christmas he will disassemble the clutches and measure them so I will know what clutches to order. We feel the bearings and races will be fine and so I will be ordering seals and shims (clutches) and that is it.

He was just chortling at the end. He has never had a benz rear apart before but he was duly impressed with the robust nature of its construction.

Hooooohaaaaaa!
