I've managed to break everything in the garage trying to remove the crank pulley on a SUP-R-C. It's a 1952 one owner and has probably never been off!! Are there any experts that can help me out with this? I've broken a t-bar (new), a two arm 6" and a 3 arm 3or 4",I'll have to go buy one,so I need to know best kind to get. I've worked on this four half days already, Thanks guys Bobby

Hi Bob, Did you see the puller made by Keith-OR?
He removed the pulley on his Super C. Hal

Hey Hal, I"ve cut one piece today and hope to finish before the weeks out, I want to sincerely "thank you and the other guys very much for your help." I have "sometimers" sometimes I"m genius and sometimers I"m a fool. This time was the latter. THANKS Bobby

We all fall into that category every now and then.
You can burn those holes, but drilling or punching looks better. The metal shops here charge $35.00 to make those brackets from 3/4"
stock. Hal

I just went through the same thing rebuilding my Super A. I broke the first pulley using a jaw puller. The second one was from a crank already removed from the engine. With the use if a 20 ton press the second one slid off like butter. It's amazing how much easier it goes when you can apply the proper leverage. This may not be an option for you, as it sound as though you don't want to remove the engine but if it does break this may give you an option for a replacement.

Bob, the diameter of the hole in that plate is 2 11/16 I am going to make one tomorrow, drill a 2 3/4 hole in a piece of 3/4 X 8 X 8 plate then cut piece out so I can slide it in behind pully, I'm going to use porta power instead of a bottle jack.

A porta power is better, some hydraulic jacks won't work on their side. Hal

Hal, I can never get lucky enough to find a bottle jack that will work on its side. We are not quite ready to remove the front pully, but getting everything ready in advance. We finualy married the motor and rest of tractor Sunday. Since we are this far might as replace front seal also..... .

I read your posting on removing the pulley. Don't use force to reinstall it. Put it in oven and heat it to 225 degrees F. Check that pulley hub for any wear. Those old seals are known to wear a groove into the hub. It's easy to fix with a speedi-sleeve from Chicago- Rawhide. Send me an email I wanted to ask you few questions on the measurements. Hal

Those bottle jacks are designed to be used in the vertical plane. We had trouble using them in the horizontal plane and they would quit working, but fine when vertical. Porta Power will work either way. We were trying to get a piece of equipment to move that weighed 15 tons into the exact position from where it was removed. Porta
Power did the job. We used a mobile crane to
remove it from the building & to reset it back in the building. It was actually a test cell and it had a removable roof. When the crane went out
to make a lift they sent a rigger along too. Hal

I had to buy a large OTC bearing puller, to fit behind the pulley, and a 7 ton two jaw puller to get the pulley off my A. Once I got the right equipment and applied some heat it came off easily.

Here's a puller using a hydraulic jack. It was designed for a Cub, but measuring the pulley hub and the diameter of the pulley you can make one or have it made. You need to use a split bearing separator behind the pulley for the puller to press against so it doesn't break your pulley.
Some heat will help too. Make sure there's no set screws that need to be removed. I don't think there is any and the pulley is a pressed fit. Most metal shops can now punch 3/4 stock with 13/16" holes for the allthread. Hal

If you have a cutting torch you can make one pretty quick. You can get the 3/4 allthread from
Home Depot. Get the 36" and have them saw it in half. They have the flat washers and the hex nuts. When you get ready to reinstall the pulley, place it in your over at 225 degrees and let it get thoroughly hot. Use your welder's gloves to handle it. Be sure to clean the crankshaft where this pulley is installed too.
You need to have the bolts on the timing gear cover loose until you get the pulley installed.

You need to inspect the hub on the pulley to make sure it doesn't have a groove worn from the old oil seal. If it does Chicago-Rawhide has speedi sleeves and seals to repair this problem. Hal

Bob, take it to the shop. I know this is a headache and an extra expense but that pulley is beyond a doubt the worse part of rebuilding the engine. On my 100 (same engine) I had the shop take it off ($60) and then when I tried to put it back on after I rebuilt the engine, I broke it. There's those that will try to sell you a puller but you've still got to have the tools to make it work. This part was meant to be pressed on and pulled off at a machine shop which has the equipment to do it. The trouble is that you have to haul the motor to the shop twice--once to get it off and again to get it on. On some of the "how to" videos, they completely skip over this part of the rebuild--for good reason.

thanks for taking the time to answer, I haven't thought of a machine shop, we also have a good guy in our club that could do it,I was panicking and not thinking also I'm going to try to build the hydralic tool that Hal listed, thanks Bob

I just removed the one on my '52 SC. Though it was probably off once before, it wasn't too bad. I didn't even use an unusally big puller, but did use heat on the pulley. I am going to replace the seal anyway so wasn't overly concerned about getting it too hot, but heat applied under tension from the puller and she bagan to move before things got all that hot. I didn't even use a backer plate behind the pulley, though I'd reccommend it before putting a cheater pipe on a 3/4" breaker bar on the puller! By the way, aftermarket folks have new pulleys for about half what IH asks for them.

Thanks I hadn't thought of heating it either and I have a torch-wow-must be the cold GA mountain air. I,m armed with a bunch of ideas that I,m going to try tomorrow. thanks Bob

If it's anything like the one on a Cub you will need a good puller, preferably one using a hyd bottle jack. A regular heavy duty puller with a lot of heat may do it. You can't just pry it off.

Bobby, be thankful you haven't broken the pulley itself. I've never removed mine, but I hear they can be a bear to get off. Some of these guys have lots of experience with them and I'm sure they will sound in. It seems some heat might be in order.
