245-555 Fluid Pump Service Information
IMPORTaNT: use of non-Titan manufactured service parts
may void warranty.
The 245 Series Pumps should receive routine servicing after
approximately 1000 hours of use or earlier if there is excessive
leakage from the top packing, or if the pump strokes become
faster on one stroke or the other. The use of Titan Piston Lube,
part # 314-480 is recommended as an upper packing lubricant.
DO NOT SuBSTITuTE OIL, WaTER OR SOLvENT
for an
upper packing lubricant.
Disassembly Procedure
1. Test pump before disassembly. Follow test procedure in
Troubleshooting Guide - Fluid Section.
2. Remove siphon hose assembly.
3. Remove stanchion nuts (19) and washers (20).
4. Remove set screw between the two flats on hydraulic
motor rod. Hold the hydraulic motor rod at the wrench
flats and unthread coupling nut (25) to separate pump
from hydraulic motor.
IMPORTaNT: Never use a pipe wrench, pliers, etc. on the
chrome part of hydraulic or fluid section rod.
5. Remove roll pin (23) or jam nut on connecting rod (24).
Remove connecting rod (24) from displacement rod (18).
6. Unthread and remove foot valve (15).
7. Remove
PTFE
O-ring (13), Buna O-ring (14), ball cage
retainer (17), ball cage (12) and ball (16).
8. Remove cylinder (6).
9. Remove displacement rod (18).
10. Place piston seat (11) in a vise and use a wrench on the
flats to remove the displacement rod (18) from the piston
seat (11).
11. Remove lower packing set (10), spring (9), spring retainer
(8) and ball (7).
12. Remove upper spring retainer (4), spring (3),
PTFE
O-ring
(5) and packing set (2).
13. Clean and inspect all parts. Inspect rod’s and cylinder’s
hard chrome for grooves, dents or worn areas. Replace if
hard chrome is damaged. Inspect valve seats and replace
if cracked or worn.
Reassembly Procedure
1. Insert new upper packing set (2) into pump block (1)
IMPORTaNT: Peak of “v” packings must point upwards on
reassembly.
2. Insert upper spring (3); small end of spring must go toward
the packing set.
3. Insert upper spring retainer (4) and new O-ring (5) into
pump block (1).
IMPORTaNT: Lubricate all O-rings before assembly.
4. Place new lower packing set (2) over piston seat (11).
IMPORTaNT: Peak of “v” must point downward on
reassembly.
5. Replace spring (9), spring retainer (8) and new ball (7) on
piston seat (11).
6. Thread piston seat back onto displacement rod (18).
IMPORTaNT: use Loctite on clean threads.
7. Insert displacement rod assembly through upper packing
set (2) in pump block (1).
8. Thread cylinder (6) back into into pump block (1).
9. Insert new ball (16), ball cage (12), ball cage retainer (17)
new Buna O-ring (14) and new
PTFE
O-ring (13).
IMPORTaNT: Lubricate all O-rings into foot valve (15).
NOTE: Ball cage pin (12a) to be in lower position unless
pump is to be used for heavy block filler or
roofing materials.
10. Thread foot valve (15) back into cylinder (6).
11. Place connecting rod (23) through coupling nut (24) and
thread connecting rod (23) into displacement rod (18).
12. Replace roll pin (23) into displacement rod (18).
NOTE: It is not necessary to overtighten foot valve and
cylinder into pump block. O-ring seals perform
sealing function without excessive tightening.
Full thread engagement is sufficient. The foot
valve (15) may be rotated back up to 1/2 turn from
full engagement for convenient hose position.
For siphon hose attachment, it is critically important that
the thread of the siphon hose fit snugly into the foot valve
with the hose assembly couplings
PTFE
-taped and sealed
to prevent air inlet leakage.
