6. Using an Allen key and a wrench, remove the Lock Nut #11D and Bolt #11B that passes through the
Links #11A and the Fulcrum Assembly #9.
7. The Fulcrum Assembly #9 and Handle #10 are now detached from the Hydraulic Hand Pump. Turn the
Fulcrum Assembly #9 over and place on bench with the Stem and Knob #16A facing up.
8. Using a wrench, unscrew the Latch Screw #16B and slide the Stem and Knob #16A, Stem Spring #16C
and Retainer #16D out of the Fulcrum Assembly #9.
9. Hold the Stem and Knob #16A in one hand with the knob in the palm of your hand. Slide back to
compress the Stem Spring #16C and hold back with fingers from same hand.
The Stem Spring #16C needs only to be compressed enough to assist in the removal of the
Retainer #16D.
10. Remove the Retainer #16D and slide the Stem Spring #16C and Latch Screw #16B off the Stem and
Knob #16A.
To reassemble the Handle Latch Assembly #16, follow these instructions:
1. Inspect, repair or replace worm or defective parts as required.
2. Refer to the illustration on page twenty-nine (29) to properly orient the Latch Arm #16E positioning to the
Body #4A.
3. Slide Latch Sleeve #16G over the threads of Cap Screw #16H.
4. Place the Latch Arm #16E into the bent end of the Latch Spring #16F. The Latch Spring #16F should sit
flat against the Latch Arm #16E.
5. Position the Latch Spring #16E so it is centered over the lower hole of the Latch Arm #16E and slide the
Cap Screw #16H and Latch Sleeve #16G into the hole.
6. With the Hydraulic Hand Pump lying horizontally and the By-Pass Valve #7 towards you, position the
Latch Arm #16E against the Sealant Barrel #3 on the By-Pass Valve #7 side of the pump and the Cap
Screw #16H towards the threaded hole.
7. While in position, hold the parts together with one hand and use needle nose pliers to grab the straight
end of the Latch Spring #16F. Wind the Latch Spring #16F counter-clockwise until the end passes over
the top of Sealant Barrel #3.
CAUTION: take care not to bend the wire of the Latch Spring #16F.
8. While holding the assembly tight to the Sealant Barrel #3 slide it forward and thread Cap Screw #16H into
the hole and tighten.
The Latch Arm #16E should be snug and firm against the Sealant Barrel #3 by the Latch Spring
#16F.
9. Slide Latch Screw #16B, threaded end away from the stem knob onto Stem and Knob #16A.
10. Slide Stem Spring #16C onto Stem and Knob #16A.
11. Hold the Stem and Knob #16A in one hand with the knob in the palm of your hand. Slide back to
compress the Stem Spring #16C and hold back with fingers from same hand. Attach the Retainer #16D.
12. With the Handle #10 pointing away slide the Stem and Knob #16A into the Fulcrum Assembly #9 and
tighten Latch Screw #16B.
