Section 3 - Maintenance For Models: JGH:E:K:T Blow-Out Fittings, Rupture Disks, and Tubing Use a rupture disk that matches the blow-out fitting type and application pressure. Generally, use a rupture disk rated about 1000 psig (70 bar g ) greater than the highest MAWP cylinder. See Table A-3 in Appendix A or ER-63 for blow-out fitting cap torque. Do not over tighten cap or blow-out pressure may decrease. Fitting Rupture Disk Lincoln Fitting Lubriquip Fitting FIGURE 3-6 Blow-Out Fitting Assemblies PAGE 3-16 3/11 Cap 1/4 in. (6 mm) Dia.

Viton O-rings (90 Durometer) seal between the divider valves and baseplate and between baseplate segments. Check valves are installed at all lube port outlets. Divider valves contain metering pistons that discharge a predetermined amount of oil with each cycle in a single line, progressive lubrication system. Single or twin valves may be externally singled or cross-ported. Plug unused outlets when singling or cross-porting. Use a bypass block in any position on the baseplate. A bypass block allows addition or deletion of lubrication points without disturbing existing tubing. Plug both outlets under a bypass block. The baseplate contains the divider valve inlet and outlet connections, interrelated passageways, and built-in check valves. All lubricant piping to and from the distribution block connects to the baseplate. The baseplate consists of one inlet block, three to eight intermediate blocks, one end block, and three tie rods. The number of baseplate intermediate blocks determines the number of divider valves allowed. Each distribution block requires a minimum of three divider valves.
For Models: JGH:E:K:T Section 3 - Maintenance Distribution Block Assembly NOTE: See specific frame Parts Book for available divider valve assembly drawings, parts lists, and repair kits. 1. Thread three tie rods into inlet block until the ends flush with the top surface of the block. 2. Slide Intermediate blocks onto tie rods. Verify all o-rings are installed and discharge ports are off center toward the inlet block. 3. Slide end block onto tie rods. 4. Lay baseplate assembly on a flat surface. Use the torquing procedure in Appendix A to tighten the tie rod nuts to the torque value in Table A-3. 5. Mount the divider valves with o-rings onto the baseplate. Use the torquing recommdations in Appendix A to tighten valve screws to the torque listed in Table A-3. Piston Valve Screw Divider Valve Inlet Crossport Plate Tie Rod FIGURE 3-7 Distribution Block - Typical Inlet Block O-Rings Check Valve Intermediate Blocks Discharge Port (Outlet) Correct port position is off-center toward Inlet Block. End Block Tie Rod Nut Divider Valve Bypass Pressure Test Lubricant can leak (by-pass) from a divider valve when the divider valve piston becomes worn. Pressure test or replace all divider valves every twelve months. Testing verifies the piston fits tightly enough in the divider valve bore for adequate pressure to force oil into the injection point. The supplier pressure tests all new <strong>Ariel</strong> divider valves. To test distribution blocks for valve by-passing requires a manual purge gun with a pressure gauge capable of developing 5000 psig (350 barg ). <strong>Ariel</strong> offers an optional force feed lubrication hand purge gun with a pressure gauge (see Tools section in technical manual). Pressure test each divider valve one at a time, complete with pin indicators installed.
