The engine produces 162 lb-ft @ 4000 rpm. The 5 speed transaxle Cruiser has a final drive of 3.94! The first ratio is 3.50, second is 1.96, third is 1.36, fourth is .97 and fifth is .81. I hope you can actually see this is really is a 3 speed with two overdrive ratios. The engine really doen't produce power until it hits 4000 RPM.
A coupling nut is typically a metal fastener which is threaded on the inside. It is designed to secure two parts together by screwing the coupling nut onto the outside of another part, often a threaded rod. The outside of a coupling nut is usually hex shaped so that a wrench can tighten or loosen it.n additional type of coupling nut contains something called a sight hole. This is a hole in the outside of the nut which travels all the way through the material.
When the female and male ends are joined, the nut seals the joint by pressing the two ends tightly together. Unions are a type of very compact flange connector. Dielectric unions, with dielectric insulation, separate dissimilar metals (such as copper and galvanized steel) to prevent galvanic corrosion. When two dissimilar metals are in contact with an electrically conductive solution (ordinary tap water is conductive), they form an electrochemical couple which generates a voltage by electrolysis.
