Mechanical Seal Removal and Installation
(Engine Assembled)
The Water Pump Mechanical Seal Puller allows a technician to
replace the seal on ES50PL engines without removing the
engine and splitting the cases.
NOTE: This removal process dismantles the seal,
making it unusable for reinstallation.
1. After the coolant has been drained, remove the water pump
cover, impeller and the sealing washer.
2. Slide the main puller body over the outer portion of the
mechanical seal as shown in (Figure 3-45)and turn T–
Handle clockwise until it contacts water pump shaft.
Continue rotating until outer portion of mechanical seal is
separated from the metal seal body.
3. Insert the puller legs between the water pump drive shaft
and the remaining portion of the mechanical seal. Attach
the puller legs to the main puller body. (Figure 3-46)
4. Ensure that the split between the puller legs are fully
supported by the main body of the tool (Figure 3-46).
5. Tighten the hex socket screws on the puller legs sufficiently
so the lip of the puller legs will grasp the mechanical seal
(Figure 3-47).
