TM 9-2520-272-40 0020 INSTALL BRAKE COOLANT VALVE ASSEMBLY COMPONENTS NOTE Make sure that the right cover assembly is turned so that the internal side points up. Early models of the X200-4A Transmission have a two-piece brake coolant valve that has a brake coolant valve stem (Figure 2, Item 7) and a coolant valve (Figure 2, Item 8). Later models of the X200-4A Transmission have a product-improved, one-piece brake coolant valve (Figure 2, Item 5). Each time a two-piece conf guration is found (Figure 2, Item 7) and (Figure 2, Item 8), you must replace it with the newer one-piece brake coolant valve conf guration (Figure 2, Item 5). 1. Install new packing retainer (Figure 3, Item 6) on one-piece brake coolant valve (Figure 3, Item 5). 2. Apply petrolatum on packing retainer (Figure 3, Item 6). 3. Install one-piece brake coolant valve (Figure 3, Item 5) in bore (Figure 3, Item 9) of end cover housing, packing retainer end f rst. Push brake coolant valve until it touches the bottom of the bore. 4. Install large spring (Figure 3, Item 4) on one-piece brake coolant valve (Figure 3, Item 5). Figure 3.
