MF 135 hydraulic oil filter?

[Dry Rot]

I have taken the hydraulic oil filter out of my 135 and it is the one on the left in the photo. I was careful to take the whole thing out in one. The 'mountings' are on the right hand side along with the new filter.

Looking at the photos on the internet, the filters and housings do seem to vary. But the filter I took out has two thick rubber washers,obe on the top and one on the bottom. There is a cup shaped cap on the top and a slightly domed and perforated plate on the bottom, as in illustrations. Also, that rubber washer is on only one end of the new filter when logic seems to suggest there ought to be two, one on each end.

Am I right? Does anyone know? I've done a pretty thorough search and I am still none the wiser.

The filter I got from the dealer is going back. Wrong one. Agco is the best source.

But the one I removed is apparently cleanable and will be going back in the tractor. I am amazed there are no clear instructions on the internet about these filters. The best piece of advice I found was to strip a piece of household wiring to get wire to secure the cap on the filter. It's copper and pliable. The cap had been screwed on so tightly, I had to make a tool for getting it off. (It's meant to be finger tight). Basically, a mower plug spanner with a slot cut across it.

Edit, clean with brake cleaner and dab of grease to hold bottom ring in place

Filter all washed with petrol now and blown dry.

Just thinking how to wash out the crud left inside. Put it all back together, then 1/2 gallon of diesel, stick a pipe from the compressor in the fill hole to stir it all up, then let it out the drain hole?

I suspect that filter has been in since new. I see I bought it in 1983 from the origina; owners who got it in 1971, probably new. As I recall, it had done 1,500 hours. Around 4,800 on it now but that would only be doing 10 acres of hay a year. It is a good tractor.

Or kerosene, both flammable eh

Forget trying to clean it out, you never will do any good, just run it and clean filter bit more often than 40 years, something like yearly

Replaced filter on 148 few weeks back, last done in the 90's we were guessing, tried washing it but could not seem to get it clean, new one wasn't dear. Lift had slowed but back to full go now.
It was replaceable by removing a plate at bottom of backend, assume this is a newer incarnation from the wire ones?

Is therre anywhere I can read up about that? The filter mounting is cup shaped on the top but a domed peforated plate on the bottom. On the left of the photo below is the old blocked filter. On the right, the new (wrong) one supplied by the dealer with top mounting and the bottom one off the tractor. (Photo is upside down!). Seemed to fit OK with the blocked filter now cleaned.

The domed perforated plate on bottom seals filter bottom but allows oil through the holes into the pump, the cup shape top seals the top of filter, yet the upturned cup allows a taller filter to be used, but the skirt is to lower the oil level before drawing air into the hydraulic pump, with no skirt and saying tipping a trailer, the pump would draw air once oil level dropped below filter top, the skirt lowers the filter top oil level.

Thanks for that. There seemto be a lot of different types. Glad I got it on the right way!

Well, that's the hydraulics all back together. It works! Thanks TFF.
