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).
