MF 202 PS filter

(quoted from post at 22:34:06 09/01/17) I have a MF 202 (1963-ish) with power steering. Looks like the system is cobbled together off of another tractor...probably a MF50 or MF 65 because that's what he had for "parts tractors."

Anyway, the PS works great, but it does leak. I ordered a filter off of this site, and it is clearly of a different design than what is in there. The new filter will fit inside the reservoir, but it is smaller than the one that's in there. I can't imagine that being an issue at all.

I was planning on dumping a quart of Lucas PS stop leak into the system, but I doubt it will stop the leak...which appears to be where the unit mounts to the block. If the PS system leaks, and I am continually dumping fluid in, is there really any reason to even have a filter in there? My MF 135 has a different PS system, but I think it was ran for years and years with no filter.

If the system leaks I would think the junk is finding its way out as well. And adding fluid makes a mess with the filter splashing fluid when I dump it in. Plus, it would hold more fluid and I could probably avoid adding as often.

Any problem (like flow rate, etc) that I'm over looking here? I'll drop this filter in since I have it, but in the future I'll probably just run without unless there is some other reason besides "filtering" the fluid that's leaking out anyway.

Yours being a later production 202, you likely just ordered the wrong filter. I ordered a filter off this site for mine (a 35 utility, but functionally the same as your machine with the same parts), and had the same issue.

There was a change in pumps somewhere along the line, can't remember what year. The short fat filter you have is for the older style pumps, known as the Barnes pump. The pump on your machine is likely a Cessna like mine, and takes a taller, slightly skinnier filter in order to reach the top of the reservoir and seal properly.

If your power steering leaks out the shaft seal (fairly common) you could try what I did- I removed the seal, which is still available from a Massey dealer, grabbed a new one, shaved it down just a touch and voila, it no longer rides in the groove the old seal wore into the shaft, and no longer leaks out the nose of the pump (and down into your engine oil, because that's where its likely going)

If it's leaking from between the pump body, it's pretty easy to disassemble and apply some anaerobic gasket material to the mating surfaces to stop seepage.

The Lucas stop leak probably wont work, either, and if the shaft seal is leaking on the pump snout, I wouldn't want that stuff mixing with my engine oil.

Try filter #1023057M91, make sure you still have the spring and washer to to hold the filter in place.
