clutch removal

Has anyone else had trouble removing the primary clutch retaining bolt.
I got a 2005 750 brute a few months ago.
I want to pull the primary clutch to install a new belt. Can't get the retaining bolt loose.
I'm turning the bolt clockwise like it says in the service manual to loosen the bolt (right hand threads on primary clutch)
I've tryed 3 differant 1/2" drive air impact guns and an electric 1/2" drive gun. Will not budge.
Any ideas or helpfull hints would be great

Its left hand threaded. That means it tightens to the left of 12:00 not right as is normal...hence the term for normal bolts.. righty-tighty...lefty-loosy. To confirm, Kawie puts arrows on the clutch face showing the direction to loosen it. Its torqued to 59ftlbs. Do not go over that as it will force the hub farther over the crank and may stretch or crack it.

You do have a puller for after you get the bolt out...right?

Sorry left hand threads.
The service manual says turn clockwise to loosen. The arrow on the clutch says the same thing. turn right/clockwise to loosen. That is what I have been doing and it will not budge.
I did order a clutch puller with the belt. But I need to get the retaining bolt out first.

Don't use an impact, use your torque wrench and tire-iron through the posts to hold it. Be sure to hold it with two posts not just one.

That worked better.
A 2' breaker bar spun it right out.
Still suprized my impact guns wouldn't loosen that bolt.
Thanks for the replys.

Well the deal is, its a long bolt that has pretty good torque on it. The distance between the head and the threads is enough to make an impact twist and flex the bolt between the head and threads that it acts a little springie and the impacts loose intencity by the time it gets to the threads. If the bolt was shorter it wouldn't be such a problem. Even with your breaker bar, the first inch or so movement at the end wasn't actualy moving threads yet, just twisting the bolt shaft.

It is very important to clean the crank with acetone and the hub..and touque to exactly 69 ftlbs when going back on.
