Easiest way to remove the nut on rear pulley/clutch

I found a very simple way to remove the nut on the rear pulley the other day since I had no luck with a socket to use an impact gun. I took the entire assembly out of my bike and used a large adjustable wrench on the nut and held the wrench on the nut and with my other hand kept a firm grip on the pulley. I hit the wrench against the ground until the nut freed up and I put the adjustable wrench on the ground and placed the nut in the claws and proceeded to turn the clutch until the nut was off and the clutch and pulley separated.

To reinstall I used both feet to push the clutch back onto the rear pulley, spun the nut back on until snug and used the wrench again to tap on the ground until it was tight.

It is very easy and the spring had much less tension than I thought it would have.

I may do a video of this later.

Edit: added video.

I can't figure out what you're saying. I keep picturing you wrestling with a tranny on a Twister game mat.

Wait... that didn't sound right.

Maybe this can clear it up.

Holding the rear pulley and clutch with both hands(one side on the nut, other hand on the back side of pulley), put the adjustable wrench on the nut and reintroduce your hand over the nut side of the assembly(so wrench doesn't fall off). Hold firmly on the pulley side and hit the wrench on the ground allowing it to spin the nut. Wrench should be at a 45ish degree angle.

I will see about doing a video.

You can grind out the inside surfaces on a 6 sided 1 1/2" socket (if memory serves) by a small amount (less than 1mm per side) with a metal grinding bit on a Dremmel and then you'll have a socket that fits. I did this so that I could stand on the pulley assembly to keep it from flying in my face. The spring has enough force to send the 2-3lb clutch flying across your room/yard (probably aimed at your face).

That's hawt...sorta.

Wait, perhaps I'm sharing a bit too much.

Some added advice if you're using a non-torque wrench (I use a big-ass stillson while holding the whole clutch assembly in a soft-jawed vise). Before removing the nut, scribe a witness mark or two between the nut and the plate behind it. Re-align the marks when re-assembling and you should be pretty much spot-on with the recommended torque. Might even want to tweak it a hair or two more.

You guys are sick

...tranny wrestling...

I am just upset you got to it before I did...Me? I really couldn't relate 'cause I usually just blow the nut off with my big 1/2" GUN...WORKS EASIER AS LONG AS YOU HOLD IT CAREFUL IN YOUR HAND WHEN YOU DO IT, OTHERWISE YOU CAN HURT YOUR WRIST ...

Should this thread be renamed - with [NSFW] in the title?

A picture is worth a thousand words so the video should be worth a few more. Added to the OP.

Good trick.

Once the nut is loosened an easy way I found to compress the contra spring (instead of having to use your feet) was to drill a hole in a piece of scrap plywood. The larger surface area of the plywood allowed me to use my knees to compress the spring which gave me better control vs. sitting in a seat bent over while pushing down with my feet. I used a 2.5" hole and 3/8" plywood.
