Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Anyone happen to have a pic you can post on the chute Doing a Restore... Not sure how the OEM setup is with the washer/wave washer.....and the parts lookup suggest even a small washer between the inner chute and outer.

Well, I think this is the correct OE config Bare nut on inside of the chute Between the inner/outer chute Large Washer (small ID) Wave Washer Small metal ~disc~ (not sure what roles this plays Put the *curved ends* that would scratch facing inside the chute against the larger washer Bolt through all of this Then the smaller fender washer and then the nut.

The wavy washer acts essentially like spring that provides constant clamping force on the chute and prevent unintended movement, but enough clamping friction to prevent it from rotating.  You can control the preload of this spring by how tight the nut is. 
I no longer have the wavy washer.  Instead, I use large nylon washers back up by metal fender washer.  The nylon washer allows the chute to pivot, but the does not scratch the metal chute.  Every once in a while, I have to adjust the nut tension as the nylon material wears away.  Its not an OEM setup, and requires periodic adjustment, but I prefer how this works.
