Claims6
A tool for alignment and assembly of cylinder heads to engine blocks wherein the block is provided with a plurality of holes and the head is provided with a plurality of holes, the tool to be inserted in said holes and which comprises
- a central body,
- a longitudinal threaded bore in said central body,
- an inclined passageway in said body intersecting said bore,
- at least two balls carried in said passageway,
- a shoulder in said passageway retaining said balls therein but permitting partial exit of one ball outside of said body, wherein the ball is adapted to support said head above said block prior to its engagement with said block,
- nose piece means in threaded engagement in said central body, rotation of which in one direction permits said balls to move into said passageway and rotation in the other direction forces a portion of one ball to be partially outside said body,
- an extension connected to said central body and engaged in said holes in said block, and
- handle means for engagement of said nose piece and rotation thereof for ball movement and tool withdrawal.
