4-Ball Lowers Cross Reference Chart 4-Ball Lowers Cross Reference Chart This chart cross references earlier styles of 4-ball lowers to the current lowers, which include the TSL pump and spring loaded packings. NOTE: Replacing an earlier lower with a current lower may require a retrofit connection kit, depending on the motor used on your pump. See connection kit manual 311876 to order the correct kit for your lower and motor, if required. Earlier Lower Part No. Current Lower Part No.
Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING WARNING PERSONAL PROTECTIVE EQUIPMENT You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited to: • Protective eyewear, and hearing protection. • Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
Changing the TSL Changing the TSL Check the condition of the TSL and the level in the reservoir every week, minimum. TSL should be changed at least every month. Part No. 206995 Throat Seal Liquid (TSL) carries residue from the pump rod into the reservoir. Discoloration of the TSL fluid is to be expected during normal operation. After some time the TSL will thicken and darken, and must be replaced. Thick, dirty TSL will not pump through the lines and will harden in the pump wet-cup.
Repair Repair Replace the Throat Packings Without Disconnecting the Lower NOTE: Throat packing kits are available. See page 28. Kit parts are marked with a symbol, for example (19†). For best results, install the TSL Pump Repair Kit 24F617 each time the throat packings are changed. NOTE: To replace the throat packings as part of a complete service of the lower, see page 11. NOTE: Tool Kit 24F494 is available as an accessory.
Repair TSL Pump Repair (if present) Table 1: TSL Pump Troubleshooting Problem TSL pump not pumping TSL fluid. Cause Solution Plugged manifold (48a). Clear the manifold. Verify that the manifold is clear by blowing compressed air through the opening. Plugged check valves (48c, 48d). Clear obstruction in check valves. Plugged inlet strainer (48c). Clear strainer mesh. Damaged TSL pump piston (46). Replace TSL pump piston. NOTE: TSL Pump Repair Kit 24F617 is available. See page 28.

NOTE: Throat packing kits are available. See page 28. Kit parts are marked with a symbol, for example (19†). For best results, install the TSL Pump Repair Kit 24F617 each time the throat packings are changed. NOTE: Tool Kit 24F494 is available as an accessory.
Repair NOTE: One inlet seat (6) includes a pressure relief valve. See FIG. 3. This seat must be located exactly where shown (the left side as viewed in FIG. 4). Use the text cast into the inlet housing as a guide. 18. Place the flats of the piston nut (12) in a vise. Unscrew the rod (17) from the nut. Remove the spacer (44). Disassemble the piston (10) and remove the seal (11). 16. Remove the balls (5), inlet seats (6 and 33), and gaskets (7). NOTE: The piston spacer (44) is not present on 750cc lowers.
