Putting new water pump in MF202

Caryc · Mar 27, 2020

Anybody know what's involved in doing this? My fan self ejected one of it's blades and of course screwed up my radiator.

I can take hold of the fan and wiggle it and the pulley assembly wiggles a bit with it. So, I went ahead and ordered a new pump assembly and a new pump pulley and fan. I'll see about getting the radiator repaired once I get it out.

So what all do I need to do to get the pump and radiator out? Hopefully I don't need to start disassembling the tractor from the rear and work my way forward !! Everything else has been a PIA on that tractor.

Caryc,

loosen the generator or alternator, move the belt and pull the 6 bolts i think? its pretty simple, we didnt really remove anything on the 202 my buddy has, we did it in about 30 minutes i think, seems like we pulled the fan off first, 4 bolts there, but really no disassembly of the tractor.

you have any 3pt issues with yours?

No 3pt issues here. When I first purchased the tractor, the three point would only go up and stay there when the the tractor was started. Owner didn't know what was wrong with it. I paid 2K for it. When I got it home, I pulled the left inspection plate and found the linkage to be bound up, I guess with rust. I stuck a pry bar in there and gently pried on it until it broke loose. That was it, 3PT back to working along with a fluid change.

I forgot to say, I will also have to pull the radiator out for repair and I'm wondering how much trouble that's going to be?

the left inspection plate? as your looking at the tractor or sitting on it? if your sitting on my buddies, the left side is a pto engage, and the controls for the 3 pt are on the right, again, as sitting on it.

I dont know much about those radiators, but on the old two cylinders of that era, i found it easier to just replace the core, but i dont know how those masseys are built so im not much help there. i do have an electronic service and operators manual for the 202, from massey, if you need, i need a parts manual

Sorry, I meant the right side plate when sitting on the tractor.

Remove the hood, side panels, and the fuel tank. The radiator should come right out the top.

Unbolt the fan shroud, and unbolt the radiator, it's held in with 2 nuts underneath. Shouldn't be too hard, also it's also probably going to be a lot cheaper to just buy a new radiator than to have a radiator shop fix it (that has been my experience with radiator shops).

I called Quin Company which is my source for Massey parts. They had three different part numbers for three different radiators for the MF202. It all depends on the tractors serial number. But, of course, my serial number plate is missing on my tractor.

Thank for the info. I'm glad to hear that I don't have to pull that heavy nose piece off to get the radiator out. Thanks for the pic.

The parts book shows 2 radiators for the 202 (the 3rd one is shown for the 204 work bull).

The part numbers are 186830M91 Tractor Serial No 306493 And Up, or 180291M1 Pre Serial No 306493.

Thanks so much for the pics. I'll see which one looks most like mine when I get it out.

ptfarmer · Mar 28, 2020

From the way the top of your radiator looks it looks like the 186830M91 (later production radiator).

tlock0331 · Mar 28, 2020

ptfarmer,

i asked a question yesterday on this thread

Massey 135 / 202 3pt

if you havent read it, can you? and any thoughts? i am kinda sure it outta be something simple, but i would rather get some advice from someone that has one....thanks!

Now I'm confused. Who are you speaking to here? I haven't shown a pic of the top of my radiator so, who are you referring to by this post?

Caryc · Mar 28, 2020

My radiator doesn't exactly match either pics that ptfarmer showed above. In the pic below of my radiator you can see that the top hose connection is an elbow so the hose is straight running down to the connection on the engine.

I don't see an elbow connection on either of those pictures, although the bottom one looks like it is angled down a bit.

Anyone with a 202 that has the elbow connection on the top of your radiator, would you please give me the serial number of your tractor since I don't have the serial number on mine? I can give you my email address if you'd rather not post your serial number here.

I did check by the number plate on the engine and found out that the engine was made in 1958 but that doesn't guarantee that 1958 was the year my tractor was produced.

Don't know why I thought that was a picture of your tractor LOL. Been stuck in the house too much lately.

The only other radiator they show for the workbull tractors is part number 189573M91 which was used on the 204 workbull from tractor serial number 342499 and up. I can't find a picture of a radiator with the 189573M91 part number.

You can tell if you have a tractor above or below SN 306493 by the length of the rod that can be seen in PTFARMERS picture (upper left side of radiator).
If the rod is 10 1/4" you have SN 306493 and up.
If the rod is 19 3/8" you have SN prior to 306493.

And my book also shows only 2 radiators for a gas MF202
186830M91 SN 306493 and pp, or
180291M1 pre SN 306493.

Did you perhaps mean 9 3/8" instead of 19 3/8"?

If you did, mine would be prior to 306493. That makes sense because my Continental engine was made in 1958.

Thanks for the great tip !!! Don't know what I would do without this place.

brooktre · Mar 29, 2020

My printed book and the online parts book both say 19 3/8". Both could be typos, it does seem like a large difference. My 1958 is SN 302xxx. I'll try and measure mine sometime tomorrow.

I have the big printed parts manual and mine says 19 3/8" also.

An extra ten inches would put a lot of space between the radiator and the engine. That's got to be a typo.

brooktre · Mar 30, 2020

I didn't get an exact measurement, but it is close enough to call it 9 3/8. I guess the parts books are wrong on the length of the radiator rod. The upper nozzle on my radiator looks just like yours Caryc, so I would go with the 180291M1. That is what my 58 would take.
