Its a roller ball bearing, no taper. It cost me over 2 Benjamins. I could just keep it for another time i guess. I have no specs on the amount of play allowed. the haynes manual says .01 mm but that may in and out play i have only up and down.
From my Technical Data Passenger Cars -- Edition January 1980 (the official Mercedes-Benz data book from that time):

For the 716.XXX trannies (4-speeds)
Quote:
End play of drive shaft between radial ball bearing and front housing cover: 0.00-0.05

End play of main shaft between radial ball bearing and holding ring: 0.00

End play of countershaft measured at front transmission housing cover: 0.07-0.15
Does any of this help you?
