TM 9-2520-272-40 0056 CAUTION When you remove, handle, or install clutch packs, keep all clutch plates and plates in the same order and pointing in the same direction. Under heat and pressure, clutch plates can take on a conical shape, called coning. Each plate will be different in degree of coning. When coned plates are mixed or turned over, they cannot install properly against each other. This can prevent plates from making suff cient surface contact with each other for the clutch pack to operate effectively. When one clutch plate or plate needs to be replaced, replace the entire clutch pack. Individual clutch plates should not be replaced, because new plates will not have the surface contour of adjacent older plates, decreasing effectiveness of the clutch pack. 14.For f rst clutch pack, install one of f ve reaction plates (Figure 23, Item 52) into range pack bore. 15.Soak four friction plates (Figure 23, Item 53) in lubricating oil for two minutes prior to assembly. Install one of four friction plates (Figure 23, Item 53) onto reaction plate (Figure 23, Item 52). 16.Install internal gear (Figure 23, Item 38), shorter splines upward. 17.Install second of f ve reaction plates (Figure 23, Item 52), then second of four friction plates (Figure 23, Item 53) onto internal gear (Figure 23, Item 38) until all f ve reaction plates (Figure 23, Item 52) and all four friction plates (Figure 23, Item 53) have been installed. 0056‐16
