Drivers

Drivers Instructions

1. Using your stock drivers as a guide, find the center of the drivers.  We will use the Polaris shaft for an example.  I measure from the end of the drive shaft to the center of the center driver.  The stock measurement is 9.1875".                                                                                                                           

2. When you are done installing the new drivers.  There should be 8” between the inside edges of the anti-ratchet points.  So 9.1875” plus 4” equals 13.1875”.  That’s the measurement for the right hand driver.  The left hand one is 5.1875”.

3. Be sure you support the middle of the drivers when pressing the shaft thru the drivers.  They can be warped, if installed incorrectly.  Also only put the second one on the shaft about .25” or so.  Place the drivers and shaft on a flat surface.  You might have to adjust the second driver slightly with a mallet to get rid of any rocking of the drivers.  When you are satisfied, put the second driver on.

* All Polaris model sleds have to shorten the front of the rails to make room for the conventional drivers.

 

This is a picture of a 2011 Pro with an anti-stab installed.  Notice the measurements.  There should be nothing ahead of the little wheels of the anti-stab kit.  Be sure to taper the leading edge of the hyfax a little. You will not have to re-install the rubber rail tips.  Notice that this sled has two limiter straps, we recommend that you add one.  Finally, make sure that the small wheels outside the rails miss the rubber drive bumps.  Depending on how your drivers are installed, the track can move left and right.  If the tracks move enough that the wheels contact the drive bumps, these wheels will be torn off.  

 

This is a quick video showing how to install drivers.
The picture on the left shows a Xp, XM, or T-3 drive shaft.  You have to install both drivers from the brake side.  Notice the white install tool on the end of the shaft.  It's purpose is to stretch the inside of the driver over the sharp edge of the shaft.  I have drawn a black line on the tool and on to the shaft.  It continues to a groove on the shaft as shown.  This will give you something to "aim" at as far as getting the drivers timed correctly. 
We are now ready to press the driver on.  I have put one of the points of the inside of the driver on the black line.
This picture show that the first has been put on and is in it's correct location.  The second driver is fully on the tool and about .25" of the driver has been pushed onto the shaft.  Now use this time to put the drivers on a flat surface.  You can rotate the driver slightly to make sure that the drivers don't rock and that they are aligned with each other.  When everything is correct you can finish pushing the second driver into place.
