Forums Technical Two Stroke: Help needed TS250/1 crank oil seals Reply To: TS250/1 crank oil seals


Hi Stuart, thanks for the info. My confusion is because as I stripped the engine, both seal lip springs were on the bearing side, and the metal discs were between the oil seal and circlip.
I have a copy of the original 1977 MZ manual which state that ‘The sealing lips of the radial seal rings at dynamo and clutch side point to the left’. Indeed, watching the factory videos on YouTube for the ETZ engine rebuild, shows the left-hand oil seal with the spring towards the clutch….I release that the TS250/1 may be different from the ETZ, hence my confusion.
Thanks again
