ABSTRACT:
Disclosed is an improved puller especially adapted for removing pulleys from the shafts of engines such as lawn mower engines, small tractor engines, etc. The puller comprises generally a box-like member of heavy steel plates with one open wall. A jack screw is threadedly associated with one wall and a pulley, mounted on the shaft, is adapted to be received in position for operative thrust engagement with an opposite wall. Running in on the jack screw forces the hub or central portion of the pulley into operative thrust contact with the opposite wall, whereby the shaft is moved axially of the pulley, thus effectively removing the pulley without damage.
