This ZZ80072 cylinder head assembly is a premium loaded cylinder head core pre-fitted with valves, springs, and guides, engineered for the 4-cylinder Perkins 4.236 (4.0L) naturally aspirated diesel engine. Cast from high-nickel grey cast iron, it fits perfectly on Perkins cylinder head applications like the Massey Ferguson 165 and Landini 6500.
Factory direct wholesale.
Our premium aftermarket Perkins 4.236 cylinder head assembly delivers the thermal stability and dimensional precision required by hard-working agricultural tractors, rough-terrain forklifts, and stationary industrial generator sets. Built in strict alignment with Perkins’ legendary off-highway standards—trusted worldwide as the heart of every great machine for agricultural tractor engine parts applications—our loaded head assemblies restore original engine torque. Optimized for the 4.0L naturally aspirated 4-cylinder engine, this block directly replaces the OEM Massey Ferguson 165 block and Massey Ferguson 175/185 series engines (MF 165 head assy). Whether overhauling an MF 265, MF 275, or MF 290 tractor, repairing a Manitou forklift, or maintaining early JCB 3CX backhoe loaders, our cylinder head preserves factory alignment.
Severe agricultural operations under intense seasonal loads subject engine heads to extreme thermal and physical stresses, causing catastrophic deck surface warpage and injector sleeve leakage. Furthermore, air bubbles and sand holes inside the casting can trigger coolant passage porosity, causing internal oil-coolant mixing. To eliminate these common off-highway failures, our Perkins cylinder head wholesale selection is cast from premium high-nickel grey cast iron. Finished with dynamic CNC deck surfacing and strict water pressure leak testing, our blocks resist thermal fatigue. Additionally, the induction hardened valve seats protect against seat recession, securing durable engine compression over decades of active farming.

As a premier industrial engine cylinder head manufacturer and direct alternative to a regional UK Perkins parts supplier, we provide micro-polished cast components built to extend classic tractor engine parts durability:
Deck surface warpage on Perkins 4.236 engines is typically triggered by severe thermal cycling under high agricultural loads. When a tractor operates at full load and is then shut down immediately, localized hotspots form, leading to thermal expansion and warping of the cast surface. Our loaded cylinder head is cast from high-nickel grey cast iron with added chromium to enhance thermal transfer. Additionally, our heads undergo meticulous stress relieving during casting, and are finished with precise CNC deck surfacing. This maintains deck flatness below 0.05 mm, ensuring a permanent head gasket seal and preventing compression bypass.
The Perkins 4.236 utilizes brass or copper sleeves to house the fuel injectors inside the coolant jacket. If the seating bore is poorly machined or experiences corrosion, coolant can seep past the sleeve seals, leading to injector sleeve leakage and internal coolant mixing. To prevent this, our blocks undergo high-precision CNC boring to secure a perfect interference fit for the sleeves. Every seat is mechanically rolled and verified to guarantee it remains flush and securely seated under high operating pressures.
Yes, the ZZ80072 and 3637397M91 cross reference models are directly interchangeable. They represent the same 4-cylinder loaded cylinder head configuration designed for the Perkins 4.236 and 4.248 naturally aspirated engines. Both share identical valve diameters, intake port orientations, and fuel injector seating profiles. Rebuilders can perform a seamless drop-in replacement on Massey Ferguson 165, MF 175, MF 185, and early JCB 3CX backhoes.
To guarantee absolute block-to-head seal and prevent oil-to-coolant mixing, all of our heads undergo rigorous quality checks. First, we perform CNC deck surfacing to maintain deck flatness below 0.05 mm, ensuring a perfect seal with multi-layer steel (MLS) head gaskets. Second, every casting undergoes wet pressure leak testing up to 4 bar to inspect for internal porosity or casting flaws. This double-stage verification ensures that our tractor engine parts perform flawlessly from day one under high operating temperatures.
