Type of thread/ pipe for mf200 loader

[Eazycheeze]

Hey guys just curious if anyone knows the type of threads / pipe used for the old mf200 pump and filter. For the inlet and outlet. Not familiar with pipe thread
I need to adjust the sizing so it can fit behind my grill.
Thanks

I don't see your picture.

From the parts book it appears that 3 or 4 different pumps and plumbing arrangements were used. Some pipe fittings were used, and it looks like some O-Ring Boss Adapters were used. Also, if your pump has been replaced it might not even be one of the ones in the parts book. I can guess the suction may be 3/4'' or 1'' NPT, if it is pipe thread. The pressure side may be an ORB adapter, since replacement O-rings are shown next to the fittings/connectors. You can scroll through the parts book to find the filter and its plumbing. Here is a link to the page of pumps and their plumbing in the 200 parts book.

You can generally measure the OD of a pipe and find its size using a pipe chart. The schedule of the pipe is determined by the wall thickness. Measure the OD of your existing pipe and find it on the chart. Best if you can measure a non-threaded area. Here is a link to a chart.

Thanks Jim. Weird its showing the pictures for me. Computers
are gods gift and also a pain in his butt.



Anywho, thanks for the pipe chart. I have managed too track it
down to npt. The suction line bottom of pump ( original pump
not sure which one ) is 3/4 npt which then upsizes to 1 to
connect too the filter container. Sort of weird as too why the
pump is 3/4 and the filter housing is 1, makes me wonder if its
not original. Also the feed line to the spool off the top of pump
is 5/8 jic orb? Something special of the sorts to 3/4 jic orb on
bottom of spool. Again I aint no pro with these types of
connectors.



After some measuring and replumbing I found the sweet spot
which Ill take a picture when I have it together tomorrow. Had
too use some 45 degree 1 connectors and a street elbow and
then a few nipples and upsizing( 3/4 to 1). Luckily my local
hardware store had more options then Home Depot!



Anywho glad this is going together great! I did have to get new
hoses made; totally forgot how pricey crimp on connectors are
for hydraulics cost more then the hoses.



Side question: havent had a moment too check the loader
reservoir but if there isnt a drain on the very bottom underside,
whats the best way too clean it?



Side question 2( I lied theres more ): the breather at the top (
which still has the dip stick luckily!) the paper element under
the cap is falling apart / destroyed. Is there any mods too
replace the paper or perhaps get some vacuum filter foam and
shove it inside under the cap?



For the fluid I concluded that my princessauto brand hydraulic
fluid : TGH hydraulic fluid 36 was the cheapest with the spec
c4 too replace the original type a atf. There is so much
controversy that its hard to choose. Figure almost any fluid
would work in a standalone hydraulic system however this fluid
is a 5w-30 engine oil viscosity but designed for
transmission/gears etc. it should be great for winter..



Thanks!

Here are the pictures. Didn t have time to mount the loader so tomorrow I will.

On my MF 102 loader the drain is at the bottom of the reservoir below the fill hole. On one side of the reservoir is the fitting to the suction hose of the pump and directly opposite is another 1 inch NPT threaded hole that is plugged. Remove the plug to drain the oil. I think I can see that plug in your 3rd picture.

I added some foam to the breather cap, but later I just replaced with a new breather cap. Mine didn t have the dipstick, never did, there is a small plug about half way up the reservoir that you remove and fill until it comes out that hole. I just recently added some tubing as a sight glass so it is a little cleaner to add oil.

I tried type a trans fluid about 10 years ago, but my pump was a little noisy so I was using universal tractor fluid.

I just finished replacing the original pump (it seized) and now I am using straight hydraulic fluid in the loader reservoir ISO 46. I don t plan on using it in cold weather, and if I did I would use ISO 32.

Thanks brook. Ya I was hoping more for a drain on the complete
underside too clean well. Ended up just pouring my new stuff it
and over time itll filter out the crap and the old oil with flushing.



I will have to get foam or a new breather element but for now I
used a muscle shirt in four layers soaked in hydraulic oil so
basically a oil filter bath.



I did not notice this flag I used the breather hole but that
breather is a pain to turn off so Ill have to look for that plug
tonight.



Using this tgh fluid for the first time and either this pump is
noisy or this fluid is too light because she screams but the
hydraulics work very well for the little I tried it. Between all the
leak corrections and tipping up tractor fluids before I mounted
everything on .



I was going to use iso however it has way to high of a pour point
for our Canadian winter compared to some hvi or tgh oil which
is rated for about -43 to -50 pour point.!



Thanks again



By chance do you know what battery group and cca these mf
202 require?

Your pump looks similar to my old one. It was a Cessna and was noisy. Eventually it seized and I just replaced it with a Permco P124 pump. Much quieter.

Massey now calls for a 30E battery with 700cca. A 24 battery will fit and should work.
