181-556 Fluid Pump Service Informationimportant: Use of non-Titan manufactured service partsmay void warranty.The 181 Series Pump should receive a routine servicing afterapproximately 1000 hours of use or earlier if there is excessiveleakage from the top packing, or if pump strokes become fasteron one stroke or another. The use of Titan Lubrisolv Part #310-200 is recommended as an upper packing lubricant. donot substitute oil, water or solvent for an upper packinglubricant.Disassembly Procedure1. Test pump before disassembly. Follow test procedure inTroubleshooting Guide - Fluid Section.2. Remove siphon hose assembly.3. Remove stanchion nuts (20) and washers (21).4. If the fluid section is connected to an air motor, hold the airmotor piston rod at the wrench flats and unthread couplingnut (25) to separate pump from motor.If the motor is connected to a hydraulic motor, removeallen set screw between the two flats on hydraulic motorrod. Hold the hydraulic motor rod at the wrench flatsand unthread coupling nut (25) to separate pump fromhydraulic motor.important: Never use a pipe wrench, pliers, etc. on thechrome part of hydraulic, air or fluid section rod.5. Remove roll pin (1) on connecting rod (24). Removeconnecting rod from displacement rod (2).6. Unthread and remove foot valve (16).7. Remove Teflon O-ring (18), Buna O-ring (17), ball stopring (13), ball cage (14) and ball (15).8. Remove cylinder (12).9. Remove displacement rod (2).10. Place piston seat (11) in a vise and use a wrench on theflats to remove the displacement rod (2) from the pistonseat (11).11. Remove lower packing set (10), spring (9), spring retainer(8) and ball (19).12. Remove upper packing spring (5), O-ring (7) and packingset (4) from pump block (3).13. Clean and inspect all parts. Inspect rod or pump tube’shard chrome for grooves, dents or worn areas. Replace ifhard chrome is damaged. Inspect valve seats and replaceif cracked or worn.8. Insert ball (15), ball cage (14), ball stop retainer ring (13),Buna O-ring (17) and Teflon O-ring (18) into foot valve.important: Lubricate all O-rings.9. Thread foot valve (16) back into cylinder (12).NOTE: It is not necessary to overtighten foot valve andcylinder into pump block. O-ring seals performsealing function without excessive tightening.Full thread engagement is sufficient. The footvalve (16) may be rotated back up to 3/4 turn fromfull engagement for convenient hose position.10. Insert coupling nut (25) back onto connecting rod (24) andthread connecting rod (24) back onto displacement rod(2).Service KitsItemNo.Pump service kit, minor (Part # 182-050)PartNo.DescriptionQTY.4 175-001 Packing set, leather 17 182-007 O-ring, Teflon 110 180-002 Packing set, leather 115 178-700 Ball 117 742-223 O-ring 118 174-001 O-ring, Teflon 119 920-103 Ball 1ItemNo.Pump service kit, major (Part # 182-520)PartNo.DescriptionQTY.182-050 Pump service kit, minor 12 185-984 Rod, displacement 111 182-921 Seat, piston 112 182-932 Cylinder 1Reassembly Procedure1. Insert upper packing set (4) into pump block (7)important: Peak of “V” packings must point upwards onreassembly.2. Insert upper spring (5); small end of spring must go towardthe packing set.3. Place packing set (10) over piston seat (11).important: Peak of “V” packings must point downwardon reassembly.4. Replace spring (9), spring retainer (8) and ball on pistonseat (11).5. Thread seat back onto displacement rod (2).important: Use Loctite on clean threads.6. Insert displacement rod (2) assembly through upperpacking set (4) in pump block (3).7. Place O-ring (7) on end of cylinder (12) and thread backinto pump block (3).important: Lubricate all O-rings before assembly.© Titan Tool Inc. All rights reserved. 21
