2. The O-ring fits into a groove on the seal housing. With the
hook on the tool facing down (facing the groove), slide the
tool between the O-ring and the groove to dislodge the O-
ring.
3. Then twist the tool so the hook faces the opposite direction
(toward the shaft), and pull the O-ring out of the seal housing.
4. Discard the used O-ring.
Remove Pump Body
1. Remove the two body retaining cap screws.
2. Remove the body from the gear case. If needed, use a plastic
mallet to tap the body away from the gear case, until the
dowel pins are dislodged from the bushings.
3. Slide the body straight off the body studs to prevent
damaging the mechanical seal parts.
To lift the body of a 130, 180, 210, 220, or 320-U3, use a lifting
strap threaded through the ports on either side of the body.
4. Place the body on a protected surface with the seals facing
up to protect the seals.
