Piston & Pin Set for Massey Ferguson 375 (5-Ring)

This Piston & Pin Set (OEM # 1693921M93) is an authentic Massey Ferguson component engineered specifically for the MF 375 tractor engine. The piston is constructed from high-grade aluminum alloy, optimized for strength, thermal efficiency, and reduced weight. Its 5-ring configuration includes three compression rings and two oil control rings, ensuring superior sealing, reduced blow-by, and improved oil management. The precision-machined design guarantees exact fitment within the cylinder bore, maintaining optimal compression ratios and combustion efficiency for reliable power delivery in agricultural workloads.

The included wrist pin (piston pin) is crafted from case-hardened steel, providing exceptional shear strength and wear resistance to handle the high loads and stresses of diesel engine operation. The pin is precision-fitted to the piston and connecting rod, ensuring smooth articulation and minimizing friction. The piston’s crown and skirt are coated with anti-scuff materials to withstand high temperatures and reduce wear, even under prolonged heavy-duty use. This set is critical for maintaining engine performance, fuel efficiency, and longevity in the Massey Ferguson 375, a workhorse tractor known for its rugged reliability in farming and fieldwork.

OEM-certified and rigorously tested to meet Massey Ferguson’s strict specifications (part # 1693921M93), this piston and pin set ensures compatibility and performance identical to the original equipment. It is ideal for engine rebuilds, overhauls, or replacements in the MF 375, restoring factory power and reliability. The 5-ring design enhances sealing under varying loads, reducing oil consumption and emissions. Always verify compatibility using your tractor’s serial number or consult the service manual to confirm fitment. Trusted by farmers and technicians, this set delivers durability and precision for demanding agricultural applications.
