An universal clutch alignment tool is provided. A tool rod is assembled with a connecting mechanism, and the connecting mechanism is then assembled with a positioning pipe, thereby forming a tool for assembling/disassembling a clutch. The connecting mechanism includes a sleeve, a driving rod, and connecting blocks. The sleeve is made into a hollow pipe in which a driving head at one end of the driving rod is disposed. The surface of the sleeve is formed with slots respectively arranged at an angular interval in which the connecting blocks are received. The outer surface of the driving head is formed with a conical driving slope. The middle section of each driving block is provided with a V-shaped notch. The inner walls on both sides of the notch are formed with two connecting slopes symmetrical to each other. The outer edge of the driving head is inserted into the notches of the connecting blocks, so that the tool rod drives the connecting blocks via the driving rod to generate a radial expansion or retraction, thereby allowing various kinds of clutches to be assembled or disassembled.
