  • Front drive pulley bearing

    On my 2002 the bearing behind the front belt drive pulley is making some noise so I'd like to replace it. looking at the parts diagram it looks like you need to pull the shaft out in order to do this? Also the front belt pulley nut is no longer available, I thought you had to replace those nuts but maybe thats only the washer I'm thinking of. Has anybody done this job and have any tips?

    Are you sure the bearing is making noise and not the white rollers in the pulley housing?

      I took the rollers completely out and it still does it. Nut is tight and belt tension is good.

        That sucks. I never done that job but in reading from those that have it don't sound like it is too terrible of a job.

          Yeah, I'll order the parts and tackle it over the winter. It only squeaks sporadically, especially when you've been on the highway a while.

            Are you absolutely sure it is the bearing and not the belt? Belt squeak is common.

              Yea I had to replace that whole middle drive assembly on mine its not all that bad. Pretty much you'll have to remove the front drive pulley and and then take the covers off the right side so you can take the middle drive chain and the shaft and sprocket out to get at that bearing. The chain and both sprockets come off all as one, no tensioner of any kind in there. You just remove a nut that is identical to the belt pulley's and it all just slides right out shaft and all then just remove the bearing and seal and install your new one. Do watch for the spacer piece and o-ring on the shaft on the left side behind the belt pulley. You may want to check and make sure you have enough gear oil in there also if its dry that could be causing your squeak I suppose. Mine the nut came loose on the chain drive sprocket then got wedged between the chain and driven sprocket and broke the chain and cracked the case but that's how I got to buy it for $500 lol so I'm not complaining to much just make sure you lock down those nuts good and checkem every once in a while I hear those tab washers ain't worth a squat.

                I'm not 100 percent sure it's not the belt, it is very localized at the front pulley area. I'll do some more investigating this weekend. Thanks BabyCheese for the tips!

                  Wash the belt and pulleys with warm soapy water and a brush. Ride it while still wet to see if noise is still there. Don’t lube it, keep it dry. Adjust the belt with a belt adjust tool. Should be about a 1/2” deflection of the belt with 10 pounds of upward pressure at the mid point.
