How accurate does the center to center distance have to be?

The reason I ask is when installing my torque/push arms, I of course wanted to verify the alignment first. Turns out my center to center distance is about 1/8 " too much. (roughly 11 5/8 instead of 11 1/2). The problem is there is no movement on the front mounts.

Also when I first took the primary off the sled the clutch fell off as I was threading in the puller. I put it back on, torqued it to 96 ft/lbs then took it off again. It took very little effort to take off. Looking at the "witness marks" inside the clutch it appears I am only contacting the crank at the very end of the taper. Hopefully reaming the clutch will solve that (assuming it is the clutch with the problem and not the crank).

On my 05 I had neither of these issues. center to center was dead nuts and the clutch tapers seemed good. I blew zero belts in 4300+ miles and had very little vibration. I feel without addressing these two issues on my 06, I will have a vibrating belt blower on my hands.

I think all you 06 owners (both 700 & 900) might want to check these two things before the snow flies.

Thanks for the heads-up. Has IT (problems with the 06's) already started????.............. :banghead:

The center to center distance is critical on any Polaris model,do u have the proper tool to measure this?My 2006 Fusion 600 HO was off a little,but that was the offset on mine the center to center was good.I have had to shim the motor mounts before to correct this,but usually from factory u can move the engine enough to get the proper off set and center to center distance.

Yes Brock, I have the proper tool to check center to center...if you look at how the engine is mounted in the 700 & 900's you will see there is no adjustment. You basically have to pull the motor and shim the mounts.

As for the clutch, the taper is NFG. New clutch on order.

Did the dealer try using the reamer to correct the taper in the clutch?

Excusion...

Yes he did, it seemed as though the material at the very bottom of the taper was harder than the rest and the reamer would not touch it...He just ordered another clutch. I took the wieghts and spring out last night and noticed the wieghts are hitting the spyder. The motor has only been run once and already there is a couple deep gouges. I was under the impression Polaris had that problem solved.

The center to center distance is what concerns me the most as it is a huge job to correct it. What are your thoughts on that?

I am curious to see how many other sleds have the same problem. Has anyone else checked thiers?

Thanks, Paul

Is a 1/8 going to make that much diff? just asking couldnt u take that up with belt deflection adjustment?

You can probably adjust the belt tension for 1/8" CD too long. It will give you a lower first gear, and possibly less overdrive in top gear, if you have enough gearing/power/clutch setup to get into overdrive.

You should probably have the dealer ask tech support for how they want the excessive CD dealt with.

It does sound like you got one of the older clutches with too much metal in the spider by the hub. Many '05s were fixed with grinding/relieving the hub, would also recommend rebalancing as well.

I was thinking that also, I just worried that will change my final drive ratio and I will lose top end.

Yes, I've been told to adjust my belt deflection by Polaris. If I have poor top end I will have to shim the motor back.

As for the clutch, we are not gonna screw around with it, just installing a new one.

Like I said before, I wonder how many other sleds have similar issues.

Thanks for your comments, Paul

Adjusting the belt deflection for a C to C that is 1/8" too long should result in a higher first gear.

Correct, I was inside out, thinking of longer belt, this acts like a shorter belt.

You have to pull the motor reguardless of 600 conventional style or 700 & 900 lay down style to shim the motor mounts.You have to pull the motor to shim any c to c distance.

Well Brock I know on all my Edge chassis sleds or on the gen2 you can undo the mounts and tip the motor up, then slide in a slotted out shim. A far cry from what is needed on the fuse.

well i guess u no.

Nice to see Polaris is still screwing with there customers. I guess your sled got a returned clutch from the two I went through last year.
For your sake I hope this is not the start of the '05 model year all over again .... just with new graphics !!!!!
