• Order one of the "No Bore" couplings for machining a custom shaft size
• Note that "No Bore" solid couplings have no pilot hole
• In the accompanying Specification Table, these are the codes for transmission types: A=Allison, B/W=Borg Warner, C=Capitol, H=Hurth, N=Newage, P=Paragon, TD=Twin Disc, VP=Volvo Penta, Y=Yanmar, ZF=ZF
• Note: in the table, the easiest way to locate the coupling you need is to start with the flange diameter, then shaft diameter, then pilot, etc.
