New control valve groups are now used. The new control valve groups help to provide more adequate flow of hydraulic oil. This will eliminate loss of pressure in the return oil passage. Refer to Table 2 for a list of new parts and former parts for your machine. Table 1 shows the effectivity of the improved control valve groups. The 335-0418 Control Valve Spool Gp is available for field fix.
