FLUID SECTION DISASSEMBLY
Thefollowing procedure is for the installation of Fluid Section Service Kit
parts. Refer to the view on page 5. The items with three digits are on
pages5, 6 and 7.
Thesteps shown below are for one side, repeat the steps 7 thru 12 to
servicethe other side.
1. Remove four (26) cap screws, releasing (36) top manifold.
2. Remove (22) balls, (19) “O” rings and (21) seats.
3. Remove four (26) cap screws, releasing (36) bottom manifold.
4. Remove (19) “O” rings, (21) seats and (22) balls.
5. Remove eight (29) nuts, releasing (32) brackets.
6. Remove one (15) fluid cap.
7. Using a plastic mallet, tap the (124) tie rods back flush into the auxil-
iarybody.
8. Remove two (158) cap screws, releasing (154 or 155) auxiliarybody
anddiaphragm assembly.
9. Remove (159) “O” ring and one (153) “O” ring.
SSERVICENOTE:The next few steps relate only to diaphragm disas-
sembly.Furtherdisassembly wouldnotnormally be required unless
thereis damage / wear found on the (148) piston or on the face of the
(152)cylinder.
10. Using a spanner wrench to hold the (149) adapter piston and a 3/4”
socketon the (14) bolt, remove the (14) bolt, releasing (9) washer, (3)
“O”ring, (6) diaphragm plate, (7) diaphragm, (5) plate and (3) “O” ring.
11. Remove the piston assembly and inspect the (151) nut, (148) piston
assembly,(150) “O” ring and (149) adapter piston. Do not disas-
semblefurther unless damage is evident.
12. Using an “O” ring pick, remove the (165) quad ring and two (164)
back-uprings from the (163) bushing.
SSERVICENOTE: Removal of the (163) bushing should not be nec-
essary,howeverit must be checked for sharp edges and removed to
preventpossible further damage.
FLUID SECTION REASSEMBLY
SClean all parts upon reassembly.Lubricate all replacement parts
andmetallic moving parts with Key-Lube grease upon reassembly.
SSERVICENOTE: PTFE “O” rings are not resilient and they should
alwaysbe replaced with new ones.
1. Install the (164) back-up ring by pulling it apart, twist or walk it down
intothe cavity bottom inside the (163) bushing.
2. Install the (165) quad ring on top of the spiral ring by folding it in half
allowingit to get past the bushing i.d. and into the cavity.
3. Install the second (164) back-up ring as in step 1. Locate it on top of
thequad ring. Lubricate and smooth out the set with your finger to
assuregood alignment.
4. Place the (9) washer onto the (14) bolt, with the chamfer against the
bolthead, place the (3) “O” ring onto the (14) bolt and insert these
threeparts thru the (6) plate.
5. Place the (7) diaphragm onto this assembly, (see assembly note,
page5).
6. Assemble the (150) “O” ring and (148) piston assembly to the (149)
adapterpiston, securing with the (151) nut.
7. Lubricate the (152) cylinder wall and insert the piston assembly into
thecylinder and through the bushing / quad seal.
8. Apply LoctiteR#271tto the inner threads of the (149) adapter pis-
ton.
9. Place the (3) “O” ring on the end of the (149) adapter piston and slide
the(5) plate over it.
10. Thread the piston assembly and diaphragm assembly together.
Hold the piston assembly with a spanner wrench, align the dia-
phragmwith the bolt holes and torque the (14) bolt to 49 - 52 ft lbs
(66.4- 70.5 Nm).
11. Install the (159) “O” ring and the (153) large “O” ring. Assembly hint:
Aliberal amount of Key-Lube grease will hold these in place tempo-
rarily.
12. Align the (154 or 155) auxiliary body with the (125) dowel pin and
(158)cap screws, and push together, securing with two (158) cap
screws.
SCAUTION:The tie rods can tear the diaphragm and ruin it. Hold the
diaphragmagainst the pump body with your fingers when pushing
eachrod end through.
13. Align the diaphragm with the proper holes in the body and push the
rodsthrough far enough to allow installation of the (15) fluid caps. Be
certainthe flow direction is oriented correctly.
14. Assemble four (29) nuts.
15. Install two (32) brackets, securing with four (29) nuts.
SNOTE:Tighten the fluid cap nuts in a cross pattern alternately and
evenly.Torque (29) nuts to 280 - 300 in. lbs (31.6 - 33.9 Nm).
16. Assemble (22) balls, (21) seats and (19) “O” rings into the cavity in
thebottom of (15) fluid caps.
17. Assemble (36) bottom manifold to fluid caps, securing with (26) cap
screws.NOTE: Torque (26) cap screws to 120 - 140 in. lbs (13.6 -
15.8Nm).
18. Assemble (21) seats, (19) “O” rings and (22) balls into the cavity in
thetop of (15) fluid caps.
19. Assemble (36) top manifold to fluid caps, securing with (26) cap
screws.NOTE: Torque (26) cap screws to 120 - 140 in. lbs (13.6 -
15.8Nm).
