Quick question, does anyone know the socket size to use on the nut for the drive pulley? | ||
| Ourdee |
I "think" it is 1 7/8" with left hand threads. WARNING: I am not positive as my info is from posts about tubers on here. | ||

crescent | ||

... I'd have to measure it, but around 2 inches sounds right | ||
| Nillaice |
and reverse threaded IIRC | ||

1-7/8. you need a special holding tool to help insure you don't damage the transmission. it really helps to have the correct socket as well and it really hold the nut tight and makes using a tq wrench easier. this is the tool i bought. https://www.ebay.com/itm/232901023976 | ||

You can make a tool for holding the pulley if you have part of a broken belt. That tool on ebay is the bee's knees. | ||

Thanks guys, I was checking my spare sockets and found one that had been ground flush on the end. It happened to be 1 7/8 inch so I guess that’s a positive ID. Usually I’ll grind a socket like that if it has to fully engage a thin nut or bolt head, and the pulley nut is fairly thin. Already been there once, but it’s been too damn cold out to go outside and remove the belt guard just to check the size since I forgot what it was. I had also made a tool to hold the pulley out of a piece of scrap steel and two cut-off bolts. I just cut a crescent out of the steel to fit the pulley diameter and welded the bolts to the inside to match the cogs in the pulley. It grips the pulley well and I let it rest against the idler studs. Not really doing anything to the bike, I just retired and was selling off some of my tools. Sold my 3/4 set to one of the younger bucks at work, but wanted to be sure I still had what I might need for the bike. The socket happened to be a spare one of fine bone china, which usually work well in a pinch and you don’t mind grinding or cutting one up as much as you would a Snap-On. | ||

Usually I’ll grind a socket like that if it has to fully engage a thin nut or bolt head, and the pulley nut is fairly thin. I do the same. On a Harley the clutch shaft sticks way out so you have to use a very deep well socket. I took a regular socket and squared the end like you did and then parted the socket in half and welded some heavy pipe between the two. The Buell is so much easier! | ||

The absolute best tool is from Kevin Drum, KD Fab. Used it today, while never easy, a bit of heat from a propane torch and a 4’ pipe and it came right off. Reverse is correct. Not sure of the size because I have a special socket off eBay. Kevin makes a great tool and it’s quite reasonable. | ||
| Griffmeister |
And a 4’ pipe... Like everyone says, piece of cake. | ||

I made a sprocket lock and used only a three foot pipe! | ||
| Tootal |
Hmmm, equal amounts of torque yet your pipe is a foot shorter. What can we assume from this equation??  | ||

Gravity is worth 25% more there. Lump of Tungsten under his house? | ||
| Ourdee |
Different pipe diameter? | ||
| Etennuly |
Gravity.....you calling me fat? Lol What if I was pulling it up? Some times it is not the length of the pipe, but rather, how you use it!  | ||

| Natexlh1000 |
So you're saying you were pulling your shorter length pipe? Kidding aside, I didn't find my countershaft nut to be too tight. I used a standard breakerbar. (I took mine off because I thought my bearings were crapping out. Turned out my tires were terrible) | ||
| Etennuly |
I have a 6 foot pipe. But to bring that out for such a small nut job..... | ||
| Griffmeister |
Push-pull, repeat as necessary. | ||

my dad has a pneumatic 3/4 impact gun, but my air compressor doesn't have the volume to run it so I went and picked up a 3/4 to 1/2 drive adapter from HFT and ran the electric impact on it for seemingly for-ever, but it worked! | ||
| Etennuly |
Not to brag, but I have a 1" impact and plenty of air pressure from my 7.5 hp compressor to run it, I just cannot lift it to run it. I have to hire people to run it or hang its mass from the tractor bucket. It has some serious torque. Does big truck lug nuts with ease Ok..... I may be bragging a bit. | ||

I wonder if an impact driver, banging on the transmission, is such a good idea...? | ||
| Griffmeister |
I used a one inch electric impact driver to loosen the nut when I last did it. Yes, I did think it was a bad idea at the time, but the whole reason for doing it was because the transmission was already bad and I was taking everything apart. The nut is installed with high strength loctite so maybe heat would have helped. Going back together I made a tool to lock the pulley so that I could use a torque wrench, should be able to use it again if I ever have to take the nut off again. | ||
| Shoggin |
Yes. Using an impact to put massive shock loads on the trans gears is a terrible, terrible, idea. A little heat for the Loctite. a locking bar, a good socket, and a 24"' breaker bar. You should be willing to purchase those tools, if you are willing to do that job. | ||
| Ourdee |
The heat? I prefer an electric heat gun. Very controllable. |
