Massey Ferguson 5445 parts for cooling, aircon and cab

Is your Massey Ferguson 5445 running hot under heavy work, or has the air conditioning stopped blowing cold? The cause is often at the front of the engine bay. This page holds more than 400 parts for the 5445, with fan clutches and aircon compressors for cooling and climate, alongside plenty of parts for the cab, the PTO and the hitch.

How to test a fan clutch

A viscous fan clutch drives the fan harder as the engine warms up. With the engine cold and stopped, it is easy to check: turn the fan by hand. It should rotate with slight resistance. If it spins freely with no drag, or will not move at all, the clutch needs replacing. Look for oil traces around the hub as well, since a leaking clutch loses its grip. With an aircon compressor, compare the pulley and the connections with the old unit.

Swapping an aircon compressor is not a quick yard job. The refrigerant has to be recovered with proper equipment first, and after fitting the system is evacuated and recharged. Ask how much compressor oil the new unit already holds, so the system ends up with neither too much nor too little. A dry start can damage a new compressor straight away.

What else is here for the 5445

Mirrors, reference numbers and related models

A shaking mirror makes reversing with a trailer hard work. When replacing one, check the mirror arm and clamps too, because any play there will make a new mirror vibrate just the same. Adjust it from your normal seating position with the trailer straight behind, so the rear edge of the trailer is just in view.
