Hi Max,
it must be the Toe Cutters that have a 17mm top seal the sidepulls are 20 mm top and bottom, just not sure when they changed it

VICTA OIL SEAL 20mm

FITS TOP AND BOTTOM OF CRANKCASE ON

125cc & 160cc MOTORS FROM 1973 ONWARDS

AND TOP SEAL ON ALL 125cc & 160cc MOTORS

EARLIER MOTORS NEED A 17mm BOTTOM SEAL

OEM PART No.HA25003A
