Walt 339 #1 Posted September 20, 2016 I am in the process of modifying a snow thrower originally made for a vertical shaft motor to operate with a horizontal shaft. This morning Garry gave me the info on the first issue I came across of auger rotating in reverse. After mowing the lawns today I played around with the snow thrower and found that with the addition of the 2 idler sprockets I can run my chain in much the same way while maintaining full use of the tensioner sprocket. The information I need now is locations of the 2 idler sprockets that are forward of, and above and bellow the auger. Here are pictures of pulley setup ( may need to tweek it for more tension ) and the left side of thrower were I need to locate the additional sprockets.

Walt 339 #2 Posted September 21, 2016 Today I took two idler sprockets and a piece of chain and used them to try to figure out locations I need to install the idlers. I started by running the chain around auger sprocket then around the two idlers. Then I proceeded moving the idlers until clearances appeared adequate to keep the chain and 3 sprockets from being located were with chain stretch I would have any issues. Once I had my locations figured out I took a can of spray paint and shot it in centers of idlers to mark locations. The paint left me 2 perfect circles allowing me find exact center of each location of the idlers I'm adding. I came up with measurement of 2 1/8" from bend were the plate extension mounts for both and 2 1/8" from bottom for the lower mounting hole and 10" from bottom for the top hole. I'm posting a picture of 2 nuts in locations on outside of my blower were they will be when idlers are installed. I would appreciate if someone could check my measurements against were the nuts are located on the side of their snowthrower. Share this post Link to post Share on other sites
