How does this pack match the original equipment specification?

That ensures proper sealing, torque characteristics, and media fit in approved housings. Use the listed part numbers to confirm interchangeability with your engine’s recommended filter.

• Part size: D68XL65 for correct fit and sealing
• Cross-reference: replaces YANMAR 119305-35151
• Sold as two filters for back-to-back service needs

What should I check before installation?

Before fitting a replacement filter, clean the filter mounting surface and inspect the housing threads and gasket area. Hand-tighten to the manufacturer’s recommended torque and use fresh engine oil to coat the gasket for a proper seal. After installation, run the engine briefly and check for leaks and correct oil pressure before returning to normal operation.

• Confirm engine model and OEM part number
• Clean mounting surface and lubricate gasket
• Check for leaks and correct oil pressure after start-up

Why buy the two-pack instead of a single filter?

A twin-pack gives you an immediate spare for the next scheduled service, which is handy for seagoing or remote operations where a replacement may not be available. It also simplifies routine maintenance planning and reduces the risk of using an incorrect aftermarket substitute in an emergency. Buying two at once can be more economical than purchasing single filters separately.

• Keeps a ready spare for next oil change
• Useful for remote or marine applications
• Cost-effective compared with separate single purchases

Who is this for? Technicians, boat owners, fleet managers and DIY mechanics who maintain YANMAR small diesel engines will find this pack helpful. It’s intended for anyone who needs an OEM-spec replacement oil filter in the D68XL65 size—especially those running compatible GM, YM, 3JH and related models and who prefer having a spare on hand for scheduled maintenance.
