Abstract

An engine piston wrist pin installation tool, kit and method provide the ability to install a piston in an engine block while the corresponding piston rod is assembled to the crankshaft. The wrist pin aperture is first aligned with an access hole provided on the engine block, which may be performed by using a tapered alignment tool provided in the tool kit. A mounting flange configured for bolting to preformed holes in the engine block is first attached over the access hole, the alignment performed, and a tool including a cylindrical sheath that holds a wrist pin clip compressed and a rod that holds the wrist pin and clip is slid through a locking collar of the flange and secured in place. The rod is then pressed through the sheath to extend the wrist pin and wrist pin clip into the piston until the wrist pin clip snaps into place.
