Converting MTD FNR transaxle for racing

Details on how I convert the MTD FNR transaxle and make it usable for mower racing.
Parts list:
3/4" keyed axle shaft
5/8" keyed axle shaft
3/4" shaft lock collars (2)
5/8" shaft lock collar
1203 12 2RS bearings (2)
1/4" keyway stock
#40 sprockets w/ 3/4" and 5/8" hubs
#40 chain w/ master link
3/4" and 5/8" thrust washers

Note* THIS REAR IS A "717" MODEL, WHICH HAS THE SPOT CUT OUT FOR THE BEARINGS, THE OTHER FNR MODELS LIKE THE "719" ARE THE SAME EXCEPT THEY DO NOT HAVE THE CUT OUT FOR BEARINGS. THERE ARE SONE DIFFERENCES IN INPUT SHAFTS ON SOME MODELS AS WELL. BUT OTHERWISE CAN BE BUILT THE SAME.
