MF40 Industrial Tractor

[gardner crawley]

I have a MF40 industrial tractor 1979 fitted with a Cameron Gardner Foreloda. The loader hydraulics are powered by a pump fitted onto the fan-belt pulley at the front of the engine.

The hydraulics have failed suddenly, probably caused by a breakage in the pump engine coupling.

Can anyone help with identifying the coupling and how to repair it without dismantling the front end of the tractor?

Easy enough dismantle to get what’s left of the coupling out.

any good Agri parts or hydraulic factors may stock or will easily source new coupling

You meen the pump is running directly of the crankshaft which your fan belt pully is fitted to, was it lifting fine before with plenty of lifting power ? then suddenly went to nothing ? first thing first is there oil in the resaviour ? when was the filter last changed ? is the pump shaft still rotating when engine running ? if all above all OK ,  get in there with a spanner or 2 Your not going to repair it with out doing something, get pump off and connector check connector, check pump shaft is rotating but not to freely, there should be some resistance,, personally i dont think a new connector and pump would break the bank for that, whitehouse products would be well worth a call for new pump,
