Caution: It is important that only the tool, shown in (B), is used to fit the new coolant seal.
The coolant seal is an interference fit on the shaft and a tool will be necessary to fit the seal correctly.
The tool should be made of mild steel bar to the dimensions shown in (B), listed as follows:
A 44,0 mm (1.73 in)
B 40,0 mm (1.57 in)
C 11,6 mm (0.46 in)

The dimensions of the tool to fit the coolant seal, will ensure that the seal is the correct length after it is installed.
It will also prevent axial distortion of the seal when it is pressed onto the shaft.
Note: Do not lubricate the seal. It is important that the seal is not contaminated by oil or grease and if it is held
in the hand, it should be held by the edge of the flange. Do not damage the ring of green sealant applied to the
body of the coolant seal just behind the flange of the seal.
4 Ensure that there are no sharp edges on the edge of the shaft and put the seal into position on the end of
the shaft. Ensure that the ring of sealant is towards the bearing. Use the tool to press the seal onto the shaft
until the bottom of the seal flange is in complete contact with the pump body. Continue to apply force for
approximately ten seconds to ensure that the seal remains in position when the force is released.
