CAUTION

Do not lubricate Teflon seal lip or outside of

crankshaft before seal installation. Teflon lip

seals must be installed dry to allow transfer

of Teflon to crankshaft for proper sealing.

Seals are designed for use on either

right-hand or left-hand rotating engines.

on seal case. Failure to install correct

rotation seal will result in seal damage and

oil leaks.
