    i had the same problem when i bought my 94 max iv new, the brackets that hold the idler at the t-20 drilled holes
    were to far apart causing the idler to hit the t-20 sprocket when chain was adjusted, R.I. had to make me
    some new brackets that were shorter with the holes closer together.

    It's probably been run loose or very loose chains. Rear frame is usually worn in the slots or bent down or both. The best way I've repaired them and placed the transmission back into the proper place is to install a frame upgrade kit that used to be available from RI. The parts weld in and reinforce the frame area around the transmission bringing the frame up to 2008 specs. Look at the upright part of your frame that passes on either side of the t20. If it is bent below the mount bolt holes it's to low. When this happens the rear chain adjusters hit the sprockets before the chains are tight. There are pics posted of one of the worse frames I ever repaired. Can't get them to paste here tonite. Good luck I'm going to have some parts fabricated in the future as I'm out of the kits.

    max4 no longer eats idlers

    Just finished frame repair,thanks to all who helped with prints,photos,and good advise. I used 3/16 x3" flat steel to reinforce side frame and cross tube,also shortened idler brackets by 3/16" center to center look and seems to work great,only problem,starter motor pucked go figure,the only thing I didn't work on.

    Seems like Murphy put the engine frame on top of the ground strap,after a good wire brushing and rearangeing every thing works great,happy, happy, happy!!
