I have a better option to remove the impeller to replace the drive belt on this Craftsman self propelled lawn vacuum. After removing the bottom shroud that concealed the impeller, you can completely access the impeller. I looked at tapping the impeller and using a puller, but noticed that the inside of the impeller hub is threaded at 7/16” x 20. The motor output shaft that it’s mounted on is threaded at 5/16” x 20. I figured that if I got a 7/16” bolt, I could thread that into the impeller hub, and when it bottomed out on the motor output shaft, by continuing to turn it, it would push the impeller off the shaft. The hard part was finding a 7/16” x 20 bolt with sufficient thread and bolt length to do the job-no easy task, as they don’t seem to sell them anywhere. So, after a lot of time spent banging my head, I came up with the idea to purchase a section of 7/16” x 20 “all thread” rod, heat it and bend one end to make a handle-no go, because it was hardened steel, So I came up with the idea to grind the threads flat on opposite sides of the threaded rod in a section as wide as my bench grinder wheel to make two flat surfaces upon which to mount a crescent wrench or vice grips. Once I did this and threaded the threaded rod into the hub, I clamped down in the flat spots with my vice grips, turned the rod two turns or so, and the impeller popped right off! I then had access to the motor mounting screws, because you have to remove the motor to replace the belt, there is only enough clearance in the deck for the output shaft to go through. After that, it’s very easy to replace the belt. I was stunned to find that one of the most consumable items on this vacuum, the rubber drive belt, required so much work to replace! Truly the Achilles Heel of this unit, and a damn poor design flaw on Sears’ (or I think, Troybilt’s) account. I hope you’ll include this procedure for impeller removal,as drilling/tapping the hub for a puller is not only time consuming, but unnecessary. The 7/16” x 20 threads on the inside of the impeller hub appear to be there for the very purpose I used them. The only problem was finding a suitable threaded bolt/rod to use. I can be reached at email@example.com. I took pictures of the rod I ground down, as welll as how it looked threaded into the impeller hub.
