Have a ring & pinion set 8-33 teeth. Ratio of 4 1/8 or 4.125 slightly smaller than what fits a 4106 but still V drive.
Ring stamped 2229123. Does any one have info as to what this fits. Thanks in adv 06 Bill.
Hi, Bill.
As far as I know, 4.125:1 is stock on PD4106, PD4107 and PD4108 coaches. 4.375:1 is stock in PD4903 and PD4905 coaches. Perhaps someone else can give you the part numbers.
Good luck.
