Supersedes Service Instruction No. 1324B

May 26, 2009

MODELS AFFECTED

All direct drive series engines.

TIME OF COMPLIANCE

At anytime the front crankshaft oil seal is replaced.

The two crankcase front bearing oil seals used in Lycoming direct drive engines are the split seal and the solid ring stretch seal. The split seal is open to permit assembly around the crankshaft. The solid seal is made from a highly elastic material that allows the seal to be stretched over the crankshaft propeller flange during assembly.
