Setup 312497P 5 Prefilling Lubricant Distributor Lines Follow the following procedure exactly as written, in the order written. Filling Secondary-t o-Lube Point Lines Refer to F IG . 4. when performing this procedure . 1. Remove port plugs or performance indicators from all of the indicator po rts on front of second ary divider valves.
Setup 6 312497P 4. Continue to stroke the pump until the lubricant purges all the air out of the internal pa ssages of th e secondary divide r valve and lubrican t flows freely from all indicator ports with no evidence of included air.
Repair 312497P 7 Repair General Repair Instructions • Before performing an y repair procedure s, relieve pressure , page 3 . • Pressure test distribution bloc ks yearly or every 8000 hours.
Repair 8 312497P Section 1: Purging Air fr om Secondary Divider Valv e Lube-to-Lube Point Lines Steps 1-6, refer to F IG . 7. 1. Install the line from the secondary divider valve to the lube point, but do not completely tighten the connection at the lube point.
Repair 312497P 9 Section 2: Purging Air fr om Master to Secondary Divider Valve Lube Lines Steps 1- 9, refer to F IG . 8. 1. Install the lines from the master divider valve to the secondary divid er valve, bu t do not co mpletely tighten the connection at the secon dary divider valve’s inlet.
Repair 10 312497P Section 3: Purging Air from Pump to Master Divider Valve Lines Steps 1-3, refer to F IG . 9. 1. Install the line from the system pump to the master divider valve, but do not comple tely tighten the con- nection at the master valve’s lube inlet.
Repair 312497P 11 Section 4: Purging Air After Adding or Replacing a Master Divider Valve Module Steps 1-7, refer to F IG . 10. 1. Install the new or replacement mod ule into the mas- ter divider valve assembly.
Repair 12 312497P Section 5: Purging Air Afte r Adding or Replacing a Seco ndary Divider Valve Module Steps 1-8, refer to F IG . 11. 1. Install the new or replacement mod ule to the sec- ondary divider valve assembly. Also connect the tubing or hoses to the a ppropriate lubrica tion point if the new/replacement module is a base section.
Repair 312497P 13 Locating and Repairing Blockages Blocks will cause a higher than normal pumping pres- sure. Depending on the applicatio n or system design, this blockage will usually re sult in a complete loss of lubricant flow into the tota l system and no bearing will be receiving lubrication.
Repair 14 312497P 4a. Master Divider Valve Equipped With Performance Indicator With manual pump co nnected to the m aster divider valve as outlined in Locating Blockages, Step 3, raise pressure to 2000 psi (14 M Pa, 138 bar). Th e indicators in the indicato r ports will signal the loca- tion of the blockage.
Repair 312497P 15 fitting and slowly operate manual pum p to verify location. If blockage is in this divider valve, go to step 7. 6. Install ma nual pump into each in dicator port o f sec- ondary divid er valve in t urn and slowly operate pump (F IG .
Repair 16 312497P d. Clean section s and piston s in suitable clean sol- vent until all lubricant has been removed. e. Use compressed air to dr y and blow out a ll ports thoroughly . A small metal probe should be used to make sure all passages are clean and open.
