315-555 Fluid Pump Service Information
The 315 Series Pump should receive a routine servicing after
approximately 1000 hours of use. The appropriate Minor Service
Kit should be installed at this time. It is recommended that one
Major Service Kit be kept on hand of normal maintenance and
emergency repairs.
Packing life will be extended by the use of Piston Lube, Titan part
# 314-480 permanent solvent. Fill to 1/4” level in pump block (2).
Do not use oil or thinners as lubricant. Use Piston Lube for upper
packings only - DO NOT USE IN MOTOR OR HYDRAULIC
SYSTEM.
Disassembly Procedure
1. Disconnect coupling nut (32).
2. Remove the stanchion nuts (26) for disassembly from tank
only.
3. Unthread foot valve (18), lock ring (7) and cylinder (8).
4. Drop spring retainer (5).
5. Remove displacement rod (1) by sliding it downward.
6. Remove packing spring (4) and packing set (3).
7. To loosen piston seat (17) and displacement rod:
a. Hold piston seat in vise.
b. Insert 1/2” bar into uid holes in displacement rod (1)
and turn.
8. Remove packing set (12) and spring retainer (10).
9. Remove lock nuts (24) to diassemble foot valve and
remove plate (22) and ball (19).
Reassembly Procedure
1. Replace new packing set (3) into pump block (2). Peak of
packings should point toward motor as illustrated.
2. Replace packing spring retainer (5). Replace new O-ring
(6) into pump block (2).
3. Replace new ball (16) in piston seat (17) and replace
spring retainer (10), spring (11), retainer (12) and new
packing set (3).
4. Tighten displacement rod (1) on to piston seat.
5. Insert displacement rod (1) through pump block (2) slowly
to avoid damaging packing set (3).
6. Replace new O-ring (6) in pump block (2).
7. Replace new ball (19) and new O-rings (20 & 21) in foot
valve (18).
8. Thread cylinder (8) into pump block (2) locking in spring
retainer (5).
9. Tighten lock ring (7).
10. Replace foot valve (18) in cylinder.
11. Connect upper connecting rod (31) to motor by threading
coupling nut (32) into piston rod of hydraulic motor.
IMPORTANT: It is necessary to grease the surface of
all O-rings to avoid the possibility of cutting them on
