Water Pump Mechanical Seal Removal
(Engine Installed)
Water Pump Mechanical Seal Puller:
(PN 2872105)
Replacement T-Handle:
(PN 2872106)
This tool allows a technician to replace the mechanical water
pump seal on EH50PL engines without removing the engine and
splitting the cases.
Improper or careless use of this tool or procedure
can result in a bent water pump shaft. Pump
shaft replacement requires engine removal and
crankcase separation. Use caution while
performing this procedure. Make sure that the
puller is parallel to the shaft at all times.
Do not place side loads on the water pump shaft
or strike the puller or shaft in any way.
1. After the coolant has been drained, remove the water pump
cover, impeller and the sealing washer.

and the remaining portion of the mechanical seal. Attach
the puller legs to the main puller body.
4. Ensure that the split between the puller legs is fully
supported by the main body of the tool.
5. Tighten the hex socket screws on the puller legs sufficiently
so the lip of the puller legs will grasp the mechanical seal.

cases. Pump shaft oil seal can also be replaced at this time
if necessary.

install the new mechanical seal. This tool is available
