pulley/flywheel size

Can someone tell me the TEAC capstan motor pulley size, capstan 2 speed motor rpm, flywheel diameter, and capstan diameter for the A 2300 and similar and for the 4010 and similar. The 2300 used either a 2 step pulley or single diameter pulley, one flywheel, and a single capstan shaft. Both capstan motors were AC 2 speed, NOT  DC motors. This design goes back to the early days of TEAC. most 7 inch decks of this type  would have similar  sized parts. I need the EXACT diameters of the capstan and flywheel, and the capstan motor rpm(s). None of this is published. Thanks.
