I am changing all the bearings and oil seals on my Vespa GS160 (1963).
The parts are from SIP scootershop (complete bearing and oil seal set).
My question is regarding the crankshaft bearing and oilseal.
First i fitted both the oilseal and bearing from the clutch side but was told by SIP scooters that the correct way is: bearing from clutch side and oil seal from crankshaft side. So i ordered a new oil seal and then did it the way SIP said was the correct way.
BUT BUT I just think that the SIP way looks wrong, the bearing is correct but the oil seal looks way off. It can only fit with the metal side thise way. Please see the way i fittet it first (last picture).
Please see the pictures and let me hear what you think.
This was my first fit before SIP corrected me. Both the oilseal and bearing mounted from the clutch side.
Hope you can help me out
