According to the head of Henschel's design office in 1945, the 40 12 16 B version in the [[Tiger II]] "needed a minor modification from the earlier model: it only required the removal of an auxiliary drive gear [apparently for the turret traverse drive] from inside the transmission housing to work satisfactorily."{{sfn|Jentz|Doyle|1997b|p=64}} The Tiger II's turret drive was like the Panther's, directly driven off the main driveshaft in the central circular housing below the turret basket. Thus the Olvar's aux. driveshaft that powered the Tiger I's turret drive was apparently retained in the B version in the Tiger II, but it seems to have been internally disconnected. Koch, ''Motoren Und Getriebe'' {{harv|Koch|2000|p=35}} shows a pic of of a Tiger II gearbox left in the open for 40 years without the cover, which definitely shows the splined turret auxiliary drive stub, but this would have been hidden behind the sheet metal cover which covered the whole gearbox when installed. |
