Is This The Correct Pulley

[Wheel-N-It 2,971]

Guys, I'm trying to address as much of the mechanical details as possible on my little 701 so that I can bring it to the Big Show next year. Since adopting it from a Cub Cadet orphanage last year I've cleaned and set the points, cleaned and adjusted the carburetor replaced all the worn nuts and bolts with the good anodized stuff, replaced the S/G belts and engine to transmission belt, found a transmission belt cover at the Big Show this year as the old one was missing, replaced the left rear hub and the left axle seal, changed the transmission oil and engine oil, adjusted the slack out of the transmission shifter lever and replaced the dust cover, cleaned the original glass bowl fuel filter and shut off, and bought a nice set of AG tires already mounted to a set of wheels ( at the Big Show, where else ) and have them mounted up. The original front tires are in great shape and hold air like brand new, so I'm keeping them on. 

So anyway, I take it out and drive it a little every week or two to see if anything is going to break so I can make the necessary repairs well ahead of June 2017. A few days ago I was driving it and all of a sudden it stopped moving under its own power. Checking it over quickly I discovered the transmission input shaft was spinning inside its pulley. I thought the keyway was sheared but turns out it did not have a key, and was relying on the set screw to hold the pulley to the transmission shaft. I installed a new keyway and all is well now. 

OK, after the long introduction here is my question; Here is a picture of the pulley that mounts to the transmission input shaft. Is this the correct factory installed pulley or is this a replacement? It's the correct diameter and V-groove size but it looks a little out of place to me like it's not original. I have no Roundhood experience other than this tractor, so I've got to reach out to you fellows who are more in the know. 

BTW, it was you guys who inspired me to own a Roundhood Wheel Horse. I would see some of you really enjoying yourselves with the little ones and I didn't want to miss out on the fun.

I don't know for sure Van but it doesn't look like a factory pulley. I believe the correct one is cast iron while that one looks like a pot metal one.

[Retired Wrencher 5,651]

I agree with Mike on this Van every  pulley I have ever seen It was cast . But if you can put in a key. Try and see how it works going up hills the true test.

[jdleach 525]

Didn't post on this last night Van, was rather late when I got in from the Elnora tractor show.

 

Don't know much at all about the roundies, but given my experience with the Wheel Horses I have seen, that pulley should be cast iron, and not some white metal. Looks like it came of a Murray or Crapsman. My father had a round hood from the early 60s that I used to mow with when I was a kid, and literally everything on it was cast iron. The later WH tractors, such as my black hood and the 300-500 series went to a lot of stamped steel pulleys, but no white metal ones.

 

I would try to locate a cast one. If nothing else, for originalities sake. Too, cast white metal (pot metal) can vary tremendously in quality and durability. The cheapest grades of pot metal will self destruct by cracking, swelling, and flaking apart on their own after a number of years. This is due to the mixing of dissimilar metals which react to each other over time. Higher quality alloys that are carefully measured as to content, can be as durable as aluminum alloy parts. Still, whether a good grade of pot metal, or an decent aluminum alloy, it still isn't as strong or long lasting as a plain 'ole gray cast iron part.

 

As a little bit of instruction as to why WH, and so many other manufacturers used cast iron extensively, consider this. Even today, with all the plastic and cheap manufactured goods, cast iron is still employed in many critical components in a wide variety of manufactured goods. Engine blocks, gear housings and boxes, and most machine tools such as lathes, grinders, milling machines, etc., still use gray cast iron. One of the reasons is durability of course, but another important one, is stability. Unlike most other metals and alloys, cast iron once cured, doesn't move, warp, shift, swell, or otherwise change. This property is why you can cast a lathe bed, grind it to a given size of extremely close tolerances, and it will measure the same over literally decades. It won't change, except through wear or damage. Another property is that cast iron is an outstanding bearing material. Think of all the strokes a piston ring must make over a cylinder wall to finally wear it out. There is nothing more than a very thin film of oil to help protect the two parts. You can use aluminum to make a cylinder, but it has to be a special alloy, and often after boring, they "burnish" the bore before assembly. The burnishing effectively compresses the aluminum, making it denser and longer wearing. A cast iron cylinder needs only to be bored, then honed to size. With a proper break-in, it will last for years and years.

 

Lastly, if you cannot find an original pulley, you can no doubt find a modern one of the proper diameter and width, and likely with the same bore, in cast iron or stamped steel from McMaster-Carr, or some such other industrial supply house. Although they specialize in gears, Boston Gear also makes pulleys I believe.

You can also get cast iron pulleys at a electric motor supply outfit.

You are absolutely correct Mike. I shoulda known, but fergot.

I think you need one like this. 

It came off an old 3 lug hub era trans, looks the same as the common 3 speed used throughout the sixties 

[stevasaurus 23,089]

Van, the pulley you have came from ACE or TSC.  The one you want is #1611.  It is like the one Bert is holding, and if you scroll down in that link that Oliver2-44 gave you...you will see he has a box marked #1611 there.  I think all the pulleys this guy has are NOS.

Thank you all so much Gents! I would have been back to you much sooner but i had to get up at 6, do a few chores then get on the Harley and go for a 200 mile ride to unwind from the work week. Steve, I will check out the above link and hopefully give that person some business. 

You all are terrific !!!

I agree 1611 is the one needed but I wasn't holding that one. 

Notice the painted finger nails? 

Thats not my style  

this is 

[stevasaurus 23,089]

Van, I just got done helping a couple of guys get one of those this year.  They are getting hard to come by...just so you know.  $20 is about the going rate.

Thank you Steve for the good info. $20 to be back original is money well spent in this case. I have no more than $550 in the tractor now including the AG's, so another $20 to make it right is ok with me. The engine runs good and the transmission shifts good and does not make unwanted noise.

[stevasaurus 23,089]

I missed the nails Bert...watching games as I was looking on RS, but now that I go back and look at that picture...that is a pretty sexy shot.    That pulley could be worth a lot more then $20. 

[squonk 42,614]

Personally I would have gone for white tip nails!  Unwind with a 200 mi run?  I unwound finding out I can't use my front mount mower carrier with a RD deck  I tried to unwind at the Steam Show yesterday but they kept calling me with problems. Should have turned off the phone but I needed it's camera! 

[stevasaurus 23,089]

I'm going to use that picture as my deck top Mike.  Turn on the computer, make a bloody Mary and unwind. 

 

Bert, how did you get her to hold that pulley??

It was simple, I asked her too 

shes got her eye on my herd and is currently looking to buy herself a no name 14 auto with hydro lift 

[stevasaurus 23,089]

Very cool Bert and Mrs.  I would think that you guys started something for selling RED stuff in the Classifieds.  How cool is that???

Thanks Steve, I have considered selling parts as I am in possession of more than I have space for or need.

however I work full time and keep up the homestead, the better half works full time and has gone back to school full time as well. It would be difficult to ship parts in a timely manner.

Steve thank you and Oliver 2-44 for the help. I have been in contact with the seller and I'm happily sending a money order to him tomorrow. 

Wow you guys amaze me when I least expect it

You guys really are pretty amazing !

Not only did you correctly confirm to me that indeed the transmission pulley on my little 701was not original, you posted a pic of what it should look like, and gave me the part number, and found someone who had a NOS one for sale, and gave me that person's contact information. How blessed I am to have crossed paths with you !!! 

When I got home from work today there was a package in the mailbox. Guess what was inside ? 

I want to sincerely thank each and every one of you! It would have taken me ten years to have found this on my own ! You guys got one in my hand in ten days !

Edited September 20, 2016 by Wheel-N-It

[stevasaurus 23,089]

That's it !!!  You are not going to take a picture of the other side of that pulley??  Dang Van !!  That is NOS...let's see the other side.
