- This is the inner bearing spacer that fits between the two driveside main bearings on International 30/40 and CS1/CSJ aluminium-crankcases engines - they are the correct width to ensure the inner roller race of the innermost bearing should just be held off the lipped outer roller bearing race and should be used in conjunction with the corresponding outer spacer - Item 0663

These spacers are machined from high tensile EN24 steel and CNC machined 

When fitted in conjunction with item 0663 (bearing outer spacer oil ring) I have measured and can tell you that with normal RHP lipped C3 roller beairng (standard fitment and the type we have been selling for 10 years) these two inner bearings spacers will hold the inner roller bearing 15 thousandth of an inch from touching the lip of the outer bearing.  I believe this lip was provided as a safety measure, in case the left hand mainshaft nut came loose and the crankshaft started forcing against the drive side bearing . . . but better not to be touching against the lip if you dont need to!  In addition, providing items 0663 and 06664 are fitted as a matching pair in aluminium crankcases .. . it means you could probably use non-lipped bearings instead of the much harder to find lipped variety .  . .  which is a consideration as the original bearings get increasingly difficult to find
