Have a clutch puller but no impact any advice ? I know its probably a dumb question but dont want to mess anything up.
 
get it as tight as you can and hit the end of puller with hammer and a block of wood and it will usually pop rite off
 
slid a piece of wood,etc in through the primary so it wont spin and is solid,with a good puller oil the threads then just lay into it with a 1/2 drive breaker bar,she'll go.
 
fill the hole in the primary with some grease first, then thread in the puller, it acts like a hydraulic press with the grease and it will pop right off.

Have heard of this before but I'm saving this for a "last resort" clutch. I have heard it makes a H#!! of a mess when it popp's off.

...Mark.
 
it worksgood i had to do it on my 97 with a cat primary and on my viper both. had impacts too and no go. it makes a small mess, but better than heating them like some do Maxdlx
 
you guy's shouldn't be using impacts or hitting the end of the crank with a hammer, puts a lot of side load on bearings that weren't deisiged for that. Use a clutch holder & breaker bar, grease if it's really tight.
 
Nothing wrong with using impacts,thats all i use, couple hammers and she's off.

most times i use one hand to hold the clutch and the other to pull the trigger
 
If you are making a mess with the grease, you are using too much grease. You only need enough to work as a hydraulic press. Usually only 1 squirt with a grease gun.

The pullers work on threads in the primary with the end of the puller pressing against the bottom of the hole in the crank. The grease helps lube the contact point and spreads the pressure out to the point the puller doesn't really bottom (metal on metal).

Using the clutch bolt, the bolt threads engage the threads in the crank. So there isn't any pressure applied to the clutch. I don't see how this would get the clutch off.

I would not use a hammer on the puller to "pop" it loose. As mentioned above the side load on the bearings is undesireable. However an impact wrench used within reason will only put rotational (axial) shock on the crank. This is not too much unlike the forces applied when each cylinder fires. Racers for years have been using impact guns taking the clutches off dozens of times without issue. I use an impact wrench myself.

As also already mentioned above, you can get usually get them loose with a breaker bar as long as you can securely hold the clutch from spinning. I use a tool made specifically for the job, but there are other ways of holding the clutch without damaging it.

I also used an impact for years and have never hurt a Yamaha by doing so. But one thing I have not seen mentioned is what happens to counter weights and other things attached to the flywheel.

After ratteling a counter weight off a friend's flywheel by using an impact, I would not recommend using one.

A manly strap wrench, the proper puller and breaker bar is all I use anymore.

X2!! I do agree with this and the flywheel damage. I'm a doo man for now but my clutch is a real pita and the best trick I've used is teflon tape on the puller threads lean the sled up on its side boil some water and pour it in the bolt hole, thread your puller in and the tape seals the water in the heat of the water helps things loosen and the hydraulic pressure of compressing the water will make the clutch pop right off. I did it on my mach and my buddies srx, clutch was on for 2 years+, and I held it with my hand and with a 1/2 in drive ratchet popped off easier than any clutch ever. And sorry ding but you're wrong the grease is for hydraulic pressure not really to lube it. That's just a side benefit. And the water is a whole lot less messy than the grease!! Just my 0.02. Actually I should get some change back as it's more like half a cent.
