Selecting Timing Gear Case and Flywheel Housing
Front and rear crankshaft oil seals and the housing or cover gaskets are distinct entries. Identify which end of the engine is being repaired and quote the full part number rather than ordering by the word seal or cover alone.
Catalog reference: Hitachi EX120-3. Confirm the engine serial number, machine details and complete existing part number before ordering. Different part numbers sharing one diagram position must not be assumed to be interchangeable.
