Piston & Pin Massey Ferguson 240 (5-Ring)

This Piston & Pin Set (OEM # 1693921M93) is an authentic Massey Ferguson component engineered specifically for the MF 240 tractor engine. The piston is constructed from high-strength aluminum alloy, optimized for lightweight performance and resistance to thermal stress. Its 5-ring design includes three compression rings and two oil control rings, ensuring effective sealing, reduced blow-by, and efficient oil management. Precision-machined to exact OEM specifications, this piston maintains optimal cylinder clearances and combustion efficiency, delivering reliable power for agricultural tasks such as plowing, tilling, and hauling.

The included hardened steel wrist pin (piston pin) is designed to endure high shear forces and cyclic loads, ensuring smooth articulation between the piston and connecting rod. The pin’s precision fit minimizes friction and wear, while the piston’s anti-scuff skirt coating enhances durability during cold starts and high-load operations. The reinforced crown design improves resistance to heat deformation, critical for maintaining performance in diesel engines under prolonged use. This set is essential for restoring or maintaining the MF 240’s engine integrity, a tractor valued for its versatility in small to mid-scale farming.

Certified to meet Massey Ferguson’s OEM standards (part # 1693921M93), this piston and pin set guarantees compatibility and performance identical to the original equipment. The 5-ring configuration enhances compression sealing and oil control, reducing emissions and oil consumption while improving fuel efficiency. Ideal for engine rebuilds or replacements, this set ensures the MF 240 operates at peak performance. Always verify compatibility using your tractor’s serial number or consult the service manual to confirm fitment. Trusted by farmers and technicians, this OEM-grade set ensures long-lasting reliability in demanding agricultural conditions.
