MF 399T steering goes heavy.

[Dowler78]

OK so today I've noticed that after an hour or so the steering on my 399T becomes very heavy to turn when the engine is on tick over or not under load.

A slight increase in revs and it goes light again.

I'm assuming it's an oil supply issue and wondered if maybe the pump may need an over haul or replacing?

If this is the case am I right in thinking the pump is located below the alternator

Any help or advice is as always much appreciated.

What about changing the filters first,including the internal one behind the rh back wheel,behind a square plate that's held on with 4 bolts?

Jack up the axle and check the bottom steering hub bearings
