Genuine Crankcase Partner 400 chainsaw 506010301

The part is from Partner 400 which was made in 1984. The part is used. Cleaned.

Part number is 506 01 03-01.

Please note: this crankcase is a early version and may be incompatible with some Partner 400, 410, 450, 460, 490, and 510 models, especially late production versions. 

Key differences include the position of the lower starter mounting hole (located below the oil fill opening). On late-production versions, this hole is positioned lower, whereas on this crankcase it is located higher. The oil and fuel tank caps are the same size, and there is no Air Injection (Air Jet) nozzle mounting.

These are the main observed differences; however, additional variations may exist. Before purchasing, please carefully check the manufacturing year of your chainsaw and verify compatibility using the official parts catalog and part numbers (PN).
