That is not uncommon even with a plunge gauge. When putting it under load and checking at different amounts of the load the numbers can bounce from right to left bias quite often, where they end up at whatever load amount you choose is somewhat  random.
The big benefit in temp is the offset


I only would believe the numbers once I had some consistency and repeatability. Biggest advice I can give to anyone doing this is be methodical and consistent. If you don't you'll be guessimg on the variation between numbers.

I mentioned plunge gauge for the reason of keeping the measurement tool completely perpendicular. Would atleast minimize one variable. Thanks to everyone else who posted..was a big help in reading before doing this.

Quick question on this...after shimming the secondary what is the torque specs on the bolt inside chain case? (Used c&t tool) and also the torque spec for the primary clutch bolt where you attach the alignment tool to? Finishing up my alignment and want to make sure all is good!!

Believe top gear bolt is 35 ft lbs, primary clutch bolt specs are on your clutch guard. But, 85-92 ft lbs comes to mind.

Align the friggen thing with the gnr kit. Ski doo doesn’t know what they are doing with these bandaid updates.

After aligning mine and shimming the secondary I’ve noticed a big difference in clutch temps. Sled seems to mph a bit better too.

The reduction in belt dust is the BIGGEST improvement. That tells you something without a even measuring temps.

I've ordered the GnR alignment tool, polly stopper, 1 shim kit, 2ndary gear tool, primary holder tool and a 30 pack of PBR! :Cheers  Held off on QRS shim until I know their needed.  I have not had a belt go yet but I do have a significant amount of belt dust.  1050 (easier) :blush_old:  trail miles on original 391. 

 

Out of curiosity, how many have needed to shim the rear PTO mount?

Qrs shim will probably be the 1st thing you need and the cheapest.

Being an engineer you know you don't mean that when you make that last half of your first statement.   As has been discussed many times before, one has to look at the history where sled clutch belt alignment has come from.   When they basically took it out of the hands of dealers and mechanics with the Rev followed by the XP and subsequently XS and XM.... they use one 4 way and two way locators such that the belts are essentially non adjusable.  I am sure they had much more favorable belt life and fewer issues with this system over the years.   As they went to the bigger longer stroked 850 they floated it a bit more and came up with the clever offset balance clutch.   And they are learning.. and reacting as quick as a large corporation can. 

 

But I agree, one should be proactive.. if he enjoys sleds and has a modicum of knowledge.    I suspect that the tools and parts that Grip and Rip have come up with are the best way to handle the tolerance stack up of the current Gen 4 drive system for a person with some skills.   By the same token I doubt Ski-Doo as a corporation wants to go back to a mechanic adjusted belt alignment for the long term.  Although in this case the tolerance stackups may force them that way.   

 

By the same token Tim and Carey are sharp people.. and work with some more sharp people.   When and where there is a need, they have stepped in and filled that need.  

 

Alignment, belt strength/durabilty and ventilation/cooling ... have always been needed since the first CVT sled was sold and it still is today - amazing huh?    I floated, shimmed and vented my 2017 when I got it 3 years ago and have yet to have a belt issue.  

 

I take my hat off to Ski-Doo for the most enjoyable sled I have ever had and I doff it to the Grip and Rip team too.  They make a super product for those that are at the extremes of the doo tolerances.   :righton

After aligning with gnr I got almost 1000 miles out of a belt.  Before was 1500.  The issue, lots of drags, lots of hill climbs.  When I blew I was breaking trail in 2ft of powder and lots of drifts using lots of on off throttle. Couple hours of abuse.  The primary was scalding hot secondary just warm.  NOt the alignment just no cool air and not letting things cool down.

So it got worse with alignment?

 I did for this belt life.  Will see when the next belt goes.  I was abusing it bad how ever.
