Pre Season Check... Primary Clutch bolt

Check to see that the primary clutch bolt on your sled has not stretched and that the taper on the clutch bore and the PTO taper are in good shape before you run this year.

A stretched bolt will not reach torque spec.. It will have a slight hourglass shape to the part of the bolt that is the smallest diameter just above the threads.

This is especially true on the 900's that use a 96 ft lb spec and the new CFi sleds with an 80 lb torqe spec.

These instructions are for the 900 but, except for the torque rating, apply to all sleds.

Pre season attention in this area can help curb any downtime or catastophys during the season.

Now would also be the time to check/wash your belt, set the side clearance and belt deflection.

Good planning and maint. can give you a great season!!

I've been getting a lot of pms and emails lately about past posts.... so I'm moving them to the top of the pile.
Saves time searching
 
Also....Check your track clips. My 08 Dragon 800 with stock track had 4 clips that were about ready to come off, they were that loose. I tried to close them with a huge pair of channel locks and they didnt budge...tough suckers thats for sure. Need a special tool for it I would guess..
 
DD...

Call your dealer and talk to the MGR... tell them you are concerend about the saftey of those behind you and putting a hole in the cooler....

If one of those clips rockets off of there it could spear someone... Polaris should fix this or replace you track for free without a deductable since it is such a safety issue...

Use words like "limiting liability" any you should see quick results as Polaris and dealers generally want to do the right thing when it comes to safety.

The Polaris primarys are notorius for balance issues... Send yours into Power Addiction for a balance... His user-name on the forum here is 1200psi.

Good planning and maint. can give you a great season!!

I went to order this bolt ,and it came up, that it was over 15.00 to ship, sent them 3or4 emails and no one replys back, called them was put on hold for 8mins. and then when I talk to someone ,they said all orders are done online what's with that. anyone got a good used one mine does look like the hour glass.
 
If you have a dealer nearby... get it from them... tax, but no shipping.

If you don't... other options like Carls Cycles, Tri City Polaris, www.ronniesmailorder.com etc..

Shipping and packaging these days is getting expensive for business....

Locktight is really not necessary on the bolt... especially since it will keep you from getting accurate readings on re-torquing the bolt after the first ride as perscribed and at regular intervals during the season.
 
Good post seen a 900 loose a crank a few years back because of a worn out bolt.


Also if you have not sent in your used old clutch for a ballance job DO IT!!! Well worth the money some of the Polaris clutches are way off and it is worth every penny.

Not in any order here are some guys that do great work and I am sure I am missing some.

Carls Cycle also
 
And the 900 can be a lot of fun to get a primary off of also,bent a few pullers before using the "hydraulic theory".
Found it to work well on all sleds if primary has not been off in a while....
 
Busted Screw

Well the bolt or screw responsible for holding the clutch in is broke. Had the clutch off and set the torque wrench and got a bang before a click. Im screwed. It looks to be broke just before the threads inside the crank. Did I mention screwed.
Question is: What is the overall length of this one. part number 7518412. Im going to start drilling and would like to get an idea as when to stop. Going to try and drill and back it out but boy I dont know. And how do I keep the crank from turning while backing?
TIA and any suggestions are welcome and Happy New Year!

I have looked for an email and also sent myself a test email and neither has shown up.
I cant get a "screw" locally till next week and want to start drilling this weekend. Overall length of part #7518412 would really help me get an idea as to how far in I dare go.
TIA

Well I found a piece of pipe that fit around the "screw" so that I would not damage the crank while drilling. Used a larger drill to flatten the top of the busted screw and start a little pilot hole for the proper size drill bit for a #4 easy out which was bran new as my old number 4 had seen better days and I didnt want to screw this one up. Thinking I may have a shot at this I was holding the crank with my right hand, my hand please note, and started the easy out thingy that I had in a tap T handle. While holding the crank WITH MY HAND I started to screw in the easy out also with my hand and BANG!! 1/3 of the bolt backer is now broke off in the middle of the broke screw. Unfreakinbelievable.
Anyway it would appear that the Torque Master III has rocketed up the list of things Id like to do!
