Engine Core Plug for Perkins A4.236/A4.248/1004.4/1006.6 Engines – Massey Ferguson Multi-Series

Description

When you’re out in the field and notice coolant weeping from the back of your engine block, chances are you’ve got a core plug that’s given up the ghost. These little plugs seal critical openings in your engine’s coolant passages, and when they fail, you’ll lose coolant fast—something you definitely don’t need when there’s work to be done. This 50mm core plug seals the camshaft end on your Perkins engine, keeping coolant where it belongs and preventing expensive engine damage.

What You’re Getting

• Precision 1″ 31/32 (50mm) diameter for exact factory fit
• Heavy-duty construction that handles the freeze-thaw cycles and pressure changes in your cooling system
• Direct replacement for worn or corroded original plugs—no modifications needed
• OEM-quality materials that won’t crack or pop out under pressure

Built for Real Farm Work

This core plug fits the workhouse Perkins engines that power Massey Ferguson 100, 200, 500, and 600 Series tractors, along with many industrial applications. Whether you’re running heavy tillage, doing loader work, or pulling implements that really make your engine work, these engines need proper cooling to prevent costly damage. These are the tractors you’ll find on farms running everything from grain operations to cattle ranches, handling everything from mid-range work to heavy-duty commercial farming.

Made to Last

Farm equipment cooling systems deal with temperature swings, vibration, and the corrosive effects of antifreeze over time. This core plug is built to handle those conditions without the cracking or corrosion that sidelines equipment. The materials are engineered for demanding agricultural use, ensuring reliable sealing under all operating conditions.

Installation Notes

Before installing, clean the bore completely and check for any damage that might prevent a tight seal. A light coat of sealer helps ensure a permanent fix. Press the plug in flush with the block surface—don’t over-drive it or you’ll distort the sealing surface. If you’re dealing with multiple failed plugs, it’s worth checking your coolant condition and thermostat operation while you’re at it.
