MF40 Where Does The Steer Pump Filter Go?

[burgs]

Hi
The steering pump on my MF40 has a kidney shape cover on the back of it and I am wondering if the filter fits inside of it somehow?
See photos, not much room it has an after market remote header tank, not much use having a filter in it though, a strainer would be ok though?
I haven't taken the cover off yet as I don't feel making new gaskets if needed.
Any clues greatly appreciated?

Best Regards

It's inside the pump, it uses a o-ring to seal the two halves together. If the tractor serial number is before 9A143879 use seal kit 888744M93, after tractor serial number 9A143879 use seal kit 888744M92.

Hi PTF
Thanks for that I will try the later of the two and see how I go.

You may try to find the Plessey # on the pump somewhere.

Hi
Removed the steering pump tank and out popped a spring, filter was blown apart also.
Spring looks as though it is out of bigger tank model, filter also has a bigger hole than the spigot cast into the pump.
Ordered seal kit 888744M92.
The new seal fitted the spigot, but I measured the distance to the tank cover and it looked like it was touch and go as to whether the filter would stay on the spigot, so made up a spacer to put a light load on the filter when the tank was fitted.
Fitted two new steer cylinders as the other two were leaking and chrome had rusted on the rods, the steering was very heavy and wanted to turn right easier than to the left.
While changing the steer cylinder I checked to see if the hoses were connected correctly and found left cylinder to be connected wrong, the piston seals were also shot on the right cylinder :shock: go figure?.
Blew out all the hoses and left rest of emulsified oil to drain over night.
Readjusted the steering valve as per the manual and now have nice light steering, that works equally good both left and right, compared with the previous Armstrong system .
Happy with that lot.
