The invention discloses a tooling and method for slantly lifting a piston assembly, comprising a pair of transverse plates, a piston rod grip ring group and an upper beam, wherein the piston rod grip ring group comprises a main pipe clamp, an auxiliary pipe clamp, two arc-shaped bushes, a plurality of struts and shackles, and chains with hooks; the arc-shaped bushes at the inner sides of the main pipe clamp and the auxiliary pipe clamp are used for clamping the upper part of a piston rod; when a piston assembly is slantly lifted, two ends of the upper beam are connected with the two ends of the main pipe clamp respectively by virtue of the chains with the hooks and the shackles; and a hook at the lower side of an engine-room crane is used for hooking the middle part of the upper beam. A method for slantly lifting the piston assembly disclosed by the invention comprises the steps that vertically lifting the piston assembly is vertically lifted and supported on the transverse plates, and the suspension center is dropped to the upper part of the piston rod, thus realizing the purpose of slantly lifting the piston assembly. The tooling disclosed by the invention is strong in universality, low in manufacture cost, simple and convenient to operate, and the problem that slant lifting needs of multiple diesel engine piston assemblies for ships are met through adoption of arc-shaped bushes of various specifications and struts is solved.
