1953 TO35 Water pump

[hrbburn]

I seen an earlier post on here with my same issue but not 100 sure of the solution. I also have the water pump off but can't figure how to get the shaft out of the pulley assembly. The previous post said to press it out.
When I look down the long pulley extension it looks like to me it is all one piece. On the end with the small diameter piece where the fan bolts too, is that the actual water pump shaft I see inside? It appears to me to be one piece but maybe it is just rusted to that point. I just don't want to press something and just break the pump. I have the new pump but can't get the pulley assembly apart from the pump.
Thanks in advance for any help.

take it to a proper machine shop

Well I figure they are going to ask me how it comes apart, and tell me if they break it is isn't there problem. I am sure there is someone on here with experience with the same type of assembly. I just need to be clear where to press it out. I have the manual with the parts blow up but you can't tell from it where to press it apart.

I've pressed three pulleys off the water pump shaft. Used the same method on all three,heat with oxy/acetaline and a hyd. press. Two came apart fine one didn't,no rhyme or reason to it.
Be extra careful because the pulley is cast iron
and will not take any abuse. It's an expensive
mistake when you break a pulley. The engineering on the pump and pulley must have been done at Continental Engine and not by Ferguson.

been there done that,

take it to a machine shop of good report.

take a few measurements before you have them press it off so when they press the pulley onto the new pump shaft they get the pulley in the same place on the shaft.

if not your belt may not run true.

yes they will tell you that if it breaks its yours. so be prepared to buy a new pulley.

my experience, pulley came off and new one press on with no problem, shop did a good job.

Check the archives on this issue. I sent it to a reputable shop and the casting shattered. If I remember correctly, it didn't come apart the way you described. Yeah, I bought it. Had a machine shop makeup a special pulley replacement/spacer. Works like a champ. Haven!t had to replace that pump in 20 years-NAPA Dealer. Good Luck!

I've done two with your basic garage tools. Just tell him if you whant it broken i can do that my self. I'm sure anyone with a shop has done 1 or 2 and knows how brittle cast can be

Well I got the pulley separated. We had about 3000 lbs on it in the press and a torch but it wouldn't budge. We then drilled 1/2" hole down through the shaft from the top of the pulley. We drilled to the depth that the shaft was in the pulley. Then we went back to the press and it pushed out. All back together and done.
Love it when a plan comes together.

I have a MF 35 Deluxe with a Continental gas engine and the water pump is shot. I ordered a new pump and on inspection it is different from the pump on the tractor ie the old one has the pulley and fan blades attached. I have examined the new pump and there is no apparent way to attach the pulley assembly. I came to the conclusion that it is pressed on. I was planning on heating the pulley and then attempting to press it off. Would this be correct given this is a MF35 and not a TO35 (my understanding is they are the same basic tractor).

I have not removed the old pump/pulley assembly from the tractor yet, however, it would appear to me that I can not remove the pump/pulley without first removing the radiator. If anyone has a MF Shop Manual I would appreciate it if you could email me a copy of the section that deals with removing and replacing the water pump.


Thanks,
Rocky

I don't know if the tractors are the same or not but can only tell you about my experience with the TO35. I was able to take the 4 metal screws out of the shroud on each side and remove the schroud and the fan with the pump all at one time. Then when I put it back together I just slid it all back in. This saved me having to cut the radiator hoses and all the work of getting the radiator out.
As I mentioned in the ealier post I had to drill the shaft from the fan end down to about the distance that was in the fan extension. Then heated with a torch and pressed it out. I believe the shaft is 5/8 or 3/4 I forget but we drilled it with a 1/2 drill. Before drilling it we had about 4000 pounds of presure on it with the press and it wasn't coming loose.
Good luck.
