Countershaft 35613-52 is same for 52 & 53. A 54 KHK stronger shaft came out with more mass, larger splined OD. Also at least 2 gears were updated. Stronger construction and larger ID to fit new shaft. The right side of the C/S Torrington Bearing is downsized .250" OD. So new bearing now, turns less distance being smaller. You can sleeve your new small bearing OD to fit bigger
hole in case. Bronze or Steel sleeve. Also need 2 New gears to fit larger ID. In 58 we do it again. More Beefy Shaft. Corresponding gears. Good set up now. These changes are listed it the Tech History. Erik K
