Hi guys, Need a little guidance here. My neighbor has a Sears craftsman model 247.885680 tracked snow thrower. He had a problem once before where the rear track drive wheels needed replacement. He had the work done and when he took it out in the middle of the recent N.E. Blizzard BOTH tracks came off the machine. Since he has heart condition I did the property and then had to manhandle the machine back to the garage for him. Here is the question. Both the tracks seem to be okay ( no missing teeth, etc.). The sprocket wheels seem to be right ( replacements weren't available so he had his machinist make new ones) and the replaced spocket wheels seem to be proper. I believe that the tracks and wheels were not tensioned properly, because the machine literally drove out of them . NO where can I find the retensioning instructions for the tracks. Anyone know the procedure or where I can find the instructions? He has the original owners booklet and it doesn't appear to have anything. Any help appreciated.

I have a Noma Snowking snow blower model E278-4000. When the item was shipped from the factory, a “Klik Pin” was installed in the innermost hole in the left tire hub. The manual instructs the owner to remove the pin from this hole and put it in the outer most hole in the axle to allow easier mobility. By doing this, the drive train goes form posi to single wheel drive. The manual does not give any instruction how to reinstall the pin into the original hole. I have tried to reinstall the pin in the innermost hole, but the thru hole is no longer visible. I have held the right wheel stationary and rotated the left wheel, but did not see where the thru hole is in the bearing or the axle. Has anyone been able to reinsert this “Klik Pin” back into the innermost hole after removing it? Thank you.
