ABSTRACT:
A bearing carrier puller tool has a central cylindrical body member that receives a threaded puller bolt. Disposed on each side of the central body member is a mounting member that receives a puller arm threaded therein. Each puller arm has a foot portion designed to interact with an area on the bearing carrier. In one version, the foot portion is generally square and sized so that the foot portion will pass through the space between the spokes on the bearing carrier. The upper end of the foot portion is wedged into contact with the underside of a flat ridge on the bearing carrier to securely hold the foot and thus the puller arm in contact with the bearing carrier. In another version, each puller arm has a J-shaped foot portion that hooks under a spoke on the bearing carrier to securely hold the foot portion and thus the puller arm in contact with the bearing carrier. The puller bolt is designed to act on the end of the propeller drive shaft and the puller bolt has a polygonal end section so that a wench can be applied to the puller bolt to cause rotation of the puller bolt. When the puller bolt is rotated, force is applied to the end of the propeller drive shaft and the central body member rotates about the threaded bolt. This causes the puller arms to pull on the bearing carrier and withdraw the bearing carrier from the housing.
