FOR MODELS: JGZ AND JGU SECTION 4 LUBRICATION Divider Valve Block Assembly Instructions 1. Screw three tie rods into inlet block until ends are flush with surface of block. Reference Figure 4-2: on page 4-32. 2. Slide intermediate blocks onto tie rods being sure that all O-rings are installed, and the discharge ports are off center toward the inlet block. 3. Slide end block onto tie rods. 4. Lay base plate assembly on flat surface and tighten nuts to the torque value given in Section 1. 5. Mount divider valves with O-rings onto base plate and tightening mounting cap screws to the torque value given in Section 1, in alternating steps. Operation - (see Figure 4-3: and Figure 4-4:) The inlet passageway is connected to all piston bores at all times with only one piston free to move at any one time. All outlets are provided with check valves. As section 3 piston moves to the right, to position all pistons at the far right, lubricant flows to Outlet 6, see illustration 1. In this position, high pressure lubricant from the inlet through interconnecting passages flows against the right end of the section 1 piston. Lubricant flow shifts section 1 piston from right to left dispensing lubricant to Outlet 1 (see illustrations 2 & 3). Section 1 piston shift directs lubricant flow against the right side of section 2 piston (see illustration 3). Lubricant flow shifts section 2 piston from right to left dispensing lubricant to Outlet 2 (see illustrations 4 & 5). Section 2 piston shift directs lubricant flow against the right side of section 3 piston (see illustration 5) Lubricant flow shifts section 3 piston from right to left dispensing lube to Outlet 3 (see illustrations 6 & 7). Section 3 piston shift directs lubricant flow against the left side of section 1 piston (see illustration 7). Lubricant flow against left side of section 1 piston begins the second half-cycle which shifts pistons from left to right dispensing lubricant through Outlets 4, 5 and 6 of the divider valve (see illustrations 8 through 12 and illustration 1). If pistons refuse to move, bleed off pressure on divider block and check for air lock in one or more valve ports by manually shifting a piston from right to left. Remove end plug and push piston with a clean soft rod that will not damage the bore. 7/09 PAGE 4 - 33
