well it's torqued to 76 ft. lbs so your gonna have to turn it hard if you don't have an impact...........but it comes off easy.........also a regular right handed thread not left, so loosen like most nuts....

 

ee

It will not come off easily...I am afraid I broke someting...Anyone has other opinnions or experience...Martinec ???

 

I used an impact on mine...

There is really no reason to take that off though. I took mine off just to see what in the hell was back there and ended up getting the little gears out of line. It was a beyotch to get back in.

 

well

Sorry my limited english...Is an impact key a tool which turn when hitting it by hammer ???

I yes...I am afraid that it is too violent to clutch axle bearing....

 

The Yamaha manual says that there is no need to pull all of that off unless you are getting an excessive amount of clutch "chatter". An impact wrench is air driven and can put a ton of torque on a nut instantly.
Good Luck!

PEACE!!!

 

well

The reason I am asking...

I am installing the STM slipper clutch now!!!

OK...I dont have pressurised air and I have already ordered the special clutch tool---I orderred it from germany and the price was around 25 EUR....ORIGINAL YAMAHA TOOL PRICE WAS 100 EUR more....shit !!!

I would not recommend this tool. I have one and have damaged a few things using it. It is good for small things but I would be leary of beating the hell out of your clutch. If you need an impact driver there are some good electric ones. I have one made by Dewalt. Perhaps you could rent one for the weekend from some place that rents tools etc.

 

tool

This is the tool I have already ordered...over 100 € more cheap than Yamaha tool...

 

well

There is a shortage of good tips...It seems that only very rare persons have opened this 2004 R1 nut ???

 

OK, I had to pull that nut off my 99 and what I did was use a piece of 2x4 wood and then place it through the rear wheel and swingarm. Then I place the bike in 1st gear. Finally I used the socket wrench and removed the nut....VOILA....simple and effective....

 

BTW, the clutch basket is identical to my 99, here's a pic!!!

 

at work I have seen the McQuay service tech just feed the strap from a strap wrench into the gears (same as clutcth and crank primary set)to lock them so the impeller can be removed. This impeller turns 33.000 rpm and the chiller cost $200,000 so it should'nt be a problem on a lowly yamaha.

 

Do like it says above, 1sts gear, rear brake applied. It works, I have done it on numerous street bikes, MX bikes, and quads. By all means do not be afraid to put some leverage (pipe, large wrench, etc) on the ratchet to make it easier. The only thing that tool will do is grab the teeth on the basket, which are more brittle than 1st gear, with rear brake applied. The tool is not going to make the nut loosen any easier. You can even take a mallot or hammer, and tap the ratchet to break the nut loose initially.

There are plenty of good suggestion above, you just have to try them :dunno

-Brake and 1st gear
-2X4 between rim and swingarm
-Straps

No matter what you do you still have to break the nut loose, so either man up and get it done, use leverage, or tap the ratchet. It is really not that hard.

 

Lespaul66.... Sears is a large store here in the US, for your info.

Hopefully you get your clutch installed well- Good Luck
xDx

 

The best option above has to be the 2X4 wood through swingarm and wheel. works every time as long as the bike is in gear.

Worked 4 me dood...

 

Iv'e seen a guy use a piece of plywood with several holes drilled for the friction plate mounts and a larger diameter hole in the center. He mounted te plywood to theclutch boss. When you turn it the plywood will make contact with the basket and lock the clutch boss in place allowing you to turn the nut. Installation is just as easy. Personally I use an impact wrenceh. It doesn't do any damage either.

 

finally

Finally I got the tool...and how easily the nut can be opened...

This tool is more for removing the soft screws that hold rotors inplace on cars or something that will take the impact of a 5.b sledge. NOT for something like a clutch!!!

 

easy

Easy with right tool...possibility to damage something when using wrong methods....
