Looking to extend the fan on a Massey Ferguson 135 tractor water pump, Bought this tractor and someone put wrong water pump on it, fan does
not go inside shroud, it is trying to run hot, could someone give me info on a extender adapter
 
Diesel or Gasoline...?

Make and model of Engine........?

Is there a Thermostat installed in the engine...?

Is Thermostat operating properly..?

Is Thermostat installed properly...? as in flow / direction of coolant flow..

Have you pressure washed the radiator? It's surprising how much dirt can get stuck in there. When I did that to my tractor today the water ran brown for quite a while and there were pieces of leaves and grass that came out too.

Have you checked the fan belt. Tight enough? Glazed? Worn narrow? My tractor went from running hot to running cool just by changing the fan belt.
 
Where is the fan in relation to the end of the shroud? Completely out side? Outside by how much? Is it about half in and half out? How about a picture or two?

If you know it has the wrong water pump on it, it would seem that getting and installing the correct pump is the best point to repair the problem, rather than increasing the cob job by adding an adapter. JMHO
 
The fan is about 1 in out side of shroud, I didn't know nothing about a diesel tractor and thought the man was telling
the truth but boy was I wrong.Have had the injector pump worked on, replaced the temperature gauge, the power steering don't work and have a water leak some were close to the motor inlet hose,had to pay a good price for it so that is why i want to add a spacer for now. Also do you know the size of the hole where the temperature censor goes in,bought gauge and the adapters will not fit hole they were 1/4 npt 3/8 & 1/2 they all had the fitting that came on gauge but the fitting that came on gauge will screw in hole but won't tighten up to stop it from leaking,The instructions in paper said use one of the adapters but they don't fit. Thanks for any info

The fan is about 1 in outside the shroud, that is why i think it is wrong pump, the person that fixed the injector told me he thought it
was wrong pump. He said the water pump was supposed to have a plate on back to seal pump but it don't. Thanks for info
 
The tractor is diesel with Perkins engine,I haven't got around to cleaning radiator yet,just got a temperature gauge put in on it to make sure it is not running hot, haven't done any work with it yet.
 
The fan should have about 1/2 of the blade inside the shroud, 1/2 outside. That allows the air to spread, pulling more air. If the fan is totally inside the shroud, all it will do is turn the air instead of pulling it through the radiator. I just checked my MF135 Perkins gas and that's how it is set up.

1. The plate behind the water pump is an AGCO only part. Look at the online parts book and you can order it from an online vendor. I ordered from Lang Diesel in Kansas and had it in two days. My 1964 did NOT have this plate from factory. It was starting to wear through the timing cover after wearing through the 1964 paper gasket.
2.My fan is 1" outside the shroud as well. I'll post a picture if I can get one. I just ran the 135 pulling a 5' mower in heavy grass for 2 hours at 110 degrees outside temp and it stayed cool the entire time.
3.The original water pump on mine had so much slop in the bearing, I could never get my alternator belt tight. I did not realize it until I put the new water pump (purchased from this site) on and I was able to get it nice and tight.
4. I purchased a temp gauge from another site and it works fine. It came with 2 adapters. In order to get it not to leak, you need to clean the crud/scale out of wear the probe meats the capillary cable going to the gauge inside the block. If you bend the capillary tube it will not work.

I replaced my water pump, gasket, metal backing plate, fan (from this site as well), radiator, hoses, thermostat (from this site). You have to remove the gas tank to do this. The water pump, thermostat, gaskets, and AGCO backing plate are around $100 total. I would do all of those at once since you have to remove the gas tank.

I also replaced my radiator after I figured out it was overheating. It looks like someone patched it as I could only ever get 1.5 gallons after several radiator fluid flushes. The original thermostat was a rusty piece of metal that no longer worked. On your temp gauge you should see it heat up, then the needle moves quickly when the thermostat opens after warming up.

Remove your block drain and clean the rusty crud out of it as well. All of this is easy to fix as the tractor is easy to work on.
 
Here's some pics. I don't have a direct fan pic but this covers the cooling system. If you order a new radiator, look for the original part number stamp on the old one. There are a ton of different versions of the 135 even though they look the same.

Thanks for pictures, mine is 1/2 in out side if shroud do you think that would make it run hot, what is usably the temperature they run. I >haven't checked to see if it has a thermostat yet, will probably have to remove hood to do that. Again Thanks for info & pictures
 

Back to a basic diagnostic point, you posted it is "trying to run hot". What is your factual basis for this statement? What you see on the tractor gauge? Is it an original with just colored ranges on the face or a temperature gauge with degree markings? Do some checking with a non-contact temp gun/thermometer and compare to what the gauge reads. Check the area where the temp gauge probe goes in the engine, both sides of the thermostat and top and bottom of the radiator. The diesel specs in the service manual calls for a thermostat with an opening temp of 175 to 182 degrees F.

Is your fan completely 1" outside the shroud, completely 1/2" outside the shroud, or are the blades 1/2 the blade inside and 1/2 the blade outside the shroud? You have posted different dimensions.

Fix the coolant leaks and put a plate on the water pump if needed (that will also move the fan closer to the shroud. Look through the radiator from the front, with a light on the fan side. See if the fins are clear so air can pass through it. Make sure someone didn't put the fan on backwards (it happens).
 
I had the person that fixed the injector leak on it tell me that the fan was to for out of radiator to keep it from cooling the tractor, I
measured the fan from shroud again an it is 1/2 outside of shroud not any of fan is in shroud ,was checking the leak today and found the line
going to injector was not tight and fixed that. I will see tomorrow if tractor runs hot, need to bush hog tomorrow, will let you know how i
come out. Thanks for you info

Hello
Checked all you asked me to, everything were fine i even found the leak, it was dripping from a injector line,tightened it up and no more leaks, but need some info on power steering pump, how cam i tell if the pump is working have no power steering. The man i bought it from gave me a ticked where they had the hold steering assembly replaced.I bushed hogged about 1 acre and temperature stayed about 162 probably don't have a thermostate in it, but i want to get power steering going.
Thanks for any inf.
 
Hello Jim
In return to fan on tractor it must be ok, I bussed hogged about 1 acer of land and it did not run hot the
temperature out side was about 95 and it did not run hot, so i want to get started on power steering. How can
i check the power steering pump to see if it is working?
Thanks for any info

You are getting deeper into the workings of your tractor and it is much easier to properly help you if you have the manuals to guide you through the basics. Its time for you to invest in the service and operator's manuals for your tractor. The service manual has info on the whole steering system you will need to check out and repair it properly. I think the MF operator's manual publication number you need is 1448077M6. The service manual assembled in a binder is publication number 144813M92 and the same manual as a packet (you put the pages in your own binder) is # 144813M1.
You can find and purchase these at AGCOpubs.com. Most are available there as printed, download, or CD. If you look other places for used or reprint manuals look for these same publication numbers to get the right ones. This site's store sells a line of manuals you could check on. eBay often has used OEM manuals (OEM is better than the I&T brand manuals, although they can supplement each other if you get both.)

You can access the on line parts books at: https://apb.agcocorp.com/
