SEAL REMOVAL
Water Pump Mechanical Seal
Puller: (PN 2872105)
Replacement T- -Handle:
(PN 2872106)
CAUTION:
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 separa-
tion. 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.
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. (Ill. 1)
