Requirements
-
Pistons may not be in the upper TDC positions.
Note:
Instead of a hose spring sealing ring -1-, install a PTFE sealing ring (Teflon) -2-. This one has a wider sealing lip. PTFE sealing rings are
installed without oil or grease. An old style radial shaft seal (with a ring spring) maybe replaced by a PTFE sealing ring, however not the
other way around. If a PTFE sealing ring was used, then can only be used as a replacement part.
PTFE sealing rings
Note: Do not additionally oil or lubricate the sealing lip of the sealing ring.
