Description
Overview:
This crank seal is a flywheel-side oil seal for Petter single- and twin-cylinder diesel engines, manufactured to match the JC5 specification. It is a non-genuine aftermarket part made from durable, oil-resistant materials to keep lubricant inside the crankcase and contaminants out. The seal helps maintain engine efficiency and reduce wear by providing a reliable barrier at the flywheel end of the crankshaft. Sized for a precise housing fit with an outer diameter of 76.5 mm (3 inches), it is suitable for common Petter applications including PH1 and PH2, as well as AVA1 and AVA2 engines. Ideal for routine servicing or full rebuilds, it offers a practical, cost-effective replacement where the original seal has hardened, leaked, or been damaged during disassembly.
