Piston & Pin Massey Ferguson 385 (4-Ring)

This Piston & Pin Set (OEM # 1693921M93) is an authentic Massey Ferguson component engineered for the MF 385 tractor engine. The piston is forged from high-strength aluminum alloy, balancing lightweight construction with exceptional durability to withstand high combustion pressures and thermal stress. Its 4-ring design includes two compression rings and two oil control rings, ensuring effective sealing, minimized blow-by, and efficient oil management. Precision-machined to exact OEM specifications, this piston maintains proper cylinder clearances and compression ratios, delivering reliable power and fuel efficiency for demanding agricultural tasks.

The included wrist pin (piston pin) is crafted from hardened steel, offering superior shear strength and wear resistance to endure the rigorous demands of diesel engine operation. The pin is precision-fitted to ensure smooth articulation between the piston and connecting rod, reducing friction and extending component lifespan. The piston’s skirt features anti-scuff coatings to prevent wear during cold starts or high-load conditions, while the reinforced crown design enhances resistance to thermal deformation. This set is critical for maintaining the performance and longevity of the Massey Ferguson 385, a tractor renowned for its reliability in heavy-duty farming operations.

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 4-ring configuration optimizes sealing under varying loads, reducing oil consumption and emissions while improving engine responsiveness. Ideal for engine rebuilds or replacements, this set restores factory power and reliability to the MF 385. Always verify compatibility using your tractor’s serial number or consult the service manual to confirm fitment. Trusted by farmers and technicians, this set ensures durability and precision for critical agricultural applications.
