Bearing A- stock bearing- 9x22x7mm.- no milling required
Bearing B- lower pinion bearing-8x12x3.5- mill out 3.5mm with 12mm bit
Bearing C- inside main gear bearing(same size as 706) 8x16x5
Beacause this bearing replaces a flanged bushing(flange measures .5mm.) mill out only 4.5mm. with 16mm. bit to compensate for the flange.
Bearing D- outer main gear bearing 8x12x3.5mm. flanged.- mill out 3mm. with 12mm. bit.
Beacause there are no bearing retainers being used the bearings should snuggly fit in place and should not fall out by themselves. Split ring pliers should be used to change the bearings out. Good Luck!
