Reassemble the Pump
NOTE: Coat all non-thread sealed parts with ISO Pump
Oil before reassembly, to ease future disassembly.
1. Install the ball (16*) in the rod (1). Center the u-cup
(13*) on the rod (1). The lips of the u-cup must face
up. Use the piston (7) to evenly push the u-cup onto
the rod, then remove the piston. Slide the bushing
(14*) onto the rod (1). The wide end of the bushing
must face up, toward the u-cup.
NOTE: Sealing the patch on the piston threads is good
for four repackings. Use thread sealant on the piston
threads after four repackings� be sure none gets on the
ball.
2. Install the piston (7). Be careful not to damage the
sealing edges of the u-cup. Torque as specified
below.
3. Install the throat u-cup as follows:
a. Models 246831, 262647, 246832, 245971,
262648, 245972, 24Y174, 18D010, 25P857,
25P858, 25P944, and 24Y175: Grease the
u-cup (20*) and cylinder (2). Place the u-cup in
the cylinder with the lips facing down. Be
careful not to damage the sealing edges of the
u-cup. Install the packing nut (19) to properly
insert and align the u-cup, then remove the
packing nut.
b. Models 246830 and 245970: Grease the u-cup
(20*) and cylinder (2). Place the seal installation
tool (23*) in the cylinder. Place the u-cup in tool
with lips facing down. Be careful not to damage
the sealing edges of the u-cup. Press the u-cup
