Abstract
A hand tool for engagement with a partially disassembled engine connecting rod with the tool having a handle-shaped base having a channel within which angular arm members are slidably and lockably mounted. Each arm member includes an extension defining a socket for reception of a connecting rod bolt. The sockets are off-center to provide variable spacing of the sockets upon rotational positioning of the extension on its supporting arm member. A modified base of the tool provides a concave surface against which an engine crankshaft may be biased to utilize the crankshaft in a piston and connecting rod removing operation. Arm members diverge slightly for purposes of providing inherent biased engagement with connecting rod bolts.
Claims7
A tool for removing a piston and partially disassembled connecting rod with connecting rod bolts from an engine block, said tool comprising,
- a base including a handgrip and arm mounting structure defining an upwardly opening channel extending normal to said handgrip,
- right angular arm members having channel insertable segments adjustably mounted in said channel,
- means locking said arms top an adjusted laterally spaced apart position to said base whereby spaced segments of said arm members are substantially parallel with one another,
- arm extensions one each carried by said arm members and each defining a socket for the reception of an end segment of a connecting rod bolt,
- said right angular arm members each having a manually displaceable upright arm segment with the upright arm segments normally being in slightly outwardly diverging relationship with one another and adapted for manual displacement into parallel relationship for engagement with parallel connecting rod bolts with subsequent manual release of the upright arm segments permitting same to laterally engage said bolts, and
- coupling means removably coupling each of said extensions to an upright arm segment.
