secondary adjustment

my wife has a zl 800 esr and the belt slips when under load at take off. i put a new 020 arctic cat belt on it and still slips. the top of the belt is flush with the top of the secondary. would this make the belt to loose for the clutch to grab the belt? if so how do i adjust the secondary? thanks-chris

Did you clean the release compound off the new belt?
Try cleaning the clutch face with 200 grit sandpaper.

How does the inside sheaves of the primary look? Is there a black ring where the belt is riding? If so, clean that before you do anything else. Scuff the faces of the primary sheaves with a scotch-brite pad and take a brush to the sides of the new belt, as well.

Slipping in a belt is caused by lack of friction between the belt and the clutch. You are trying to maximize that friction by making sure there is no old belt residue on the clutch (the black ring) and scrubbing the new belt to make sure there is no mould release compound still on the sides. The scotch brite pad will rough up the surface and give a better grip, as well.

Adjusting the secondary will help eliminate any bog, and can help some with slippage, but start with the other two things first.

And RJ beat me to it by 4 minutes

thanks for the help. the in side of the primary is clean, if any thing there is a smooth area where the belt rides. im still going to scuf the inside of the primary and the belt to eliminate any issues that might cause slipping. i have always been told that the belt should stick up past the secondary 1/8 to 1/4 inch. the only time i had to do this was on a old 97 ultra and it seemed simple, but looking at this secondary i cant figure out what to do. i did notice to day that if i just pull up on the belt the secondary opens up really easy, every othe sled i have ever had i had to spin the back part of the secondary to get the belt off and on and it was still a slight pain to get the belt off, with this one one quick yank up the secondary opens right up (and with not much effort) if any one has any insight into my problem please let me know. thank for your time- chris

Possible that the spring needs replacing, it should not be that easy to open. Although the roller secondary is a bit different than the older button style, you should still need to give the sheave a turn to be able to get the belt off.

Start by mesureing your center to centers of the clutches! You want them to be 12 1/4" and then chech with a carpenters square that the engine is just forword of sqaure if anything! Look close at the torque stop behind the clutch! I broke mine and WOW does that motor move around!
