    Adjustment
    Note: Big Dog models have two types of axle adjusters: locking nut and hex head bolt adjuster;
    and allen socket bolt adjuster and allen lock screw. On models with the locking nut and hex head
    bolt adjuster, the chrome cover located on the end of the swingarm must be removed to gain
    access to the rear axle nut and axle adjusters.
    A misaligned rear wheel and or brake caliper could cause the rear
    brake disc to bind, resulting in severe damage and/or personal
    injury.
    1. Loosen the lock nut or allen screw securing the axle adjuster.
    2. Loosen the rear axle nylock nut.
    3. Check to insure the integrity of the nylock nut has not been compromised. If there is any
    question about the reliability of the nylock nut, it must be replaced.
    4. Turn the axle adjusters as necessary to move the axle and correctly adjust the belt tension.
    5. Turn each adjuster an equal number of turns to keep the wheel aligned.
    6. Tighten the nylock axle nut to 60 ft-lbs torque.
    7. Check rear brake caliper position on the rear disc. Disc should run true within the brake
    caliper.
    8. Check drive belt tension.
    9. Check rear wheel alignment.

    This is straight out of the manual. The set screws that push on the axle, have two set screws on each side. The first one locks the inner one, so remove the outer one first.

    The manual states 1/4 to 1/2 inch deflection at 10lbs force with riders weight for belt tension. Myself personally run mine about 1/2 inch deflection without rider on bike. Just make sure after setting belt tension to rotate your tire clockwise and see that the belt is centered on the rear pully.

    I run mine a little looser. I had my rear pulley done by SuperMax about 3 years ago and they told me that most of these belts are running to tight. I've had no problems with the looser belt. Anyway that's what I am doing.

    I had to tighten mine up. At 1/2 the wheel would shift around too much when accelerating or on decel.

    Was going to tighten my loose belt and the nut was all crushed in and deformed.

    Is this a standard part or a Big Dog Specific nut?

    I just mounted the rear and I checked the manual and it says 3/16" deflection, rider weight not required. they must be high when they wrote that.

    I'm gonna try 1" of total deflection, 1/2" up and down with rear off the ground (k9) and see what happens.

    Start with simple. Rub a bar of soap on both inner and outer edges of the belt. If it stops, you have the dreaded belt squeek......lol. If thats the case its just a matter or doin an alignment on your belt, OR you may have a worn pulley? Do some site searching on belt squeek.

    The damn things wear out, too. Mine was noisy as hell and it's easy to see why. I had a pesky oil leak for quite a few miles, and I think the oil getting on my belt attracted dirt and grit that kept abrading the pulley and produced abnormal wear. The fins on the pulley were sharp.....

    Fortunately I had another pulley, so I sent it off and got it chromed and will keep it cleaner.

    Also it's not as much of a squeak as it is a noisy rub or something hard to explain but I will try to soap
