Caution: Do not lubricate the coolant seal (E4). It is important that it is not contaminated with oil or grease and,
if it is held in the hand, it should be held by the edge of the outside flange. Do not damage the ring of green
sealant applied to the body of the coolant seal just behind the flange.
8 With the widest end of the coolant seal towards the oil seal, push the seal onto the shaft until it is in contact
with the coolant seal counterbore. Ensure that the seal is square with the bore and press the seal into the
counterbore, with a suitable adaptor, until the outer flange is in contact with the pump body. The adaptor must
apply force only to the outer flange of the seal. Continue to apply force for approximately ten seconds to ensure
that the seal remains in position.
A tool (F) can be made to press the new seal into position. The tool should be made of a suitable material to
the dimensions shown below:
A 44,0 mm (1.73 in)
B 40,0 mm (1.57 in)
C 12,2 mm (0.48 in)
D 35,8 mm (1.41 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.
9 Ensure that the drive end of the shaft has support. Use a suitable distance piece and a flat bar to press the
impeller (E3) onto the shaft until the front face of the impeller is 10,35/10,48 mm (0.41/0.40 in) from the front
face of the pump body (E5). This dimension will ensure an impeller clearance (E1) of 0,44/1,06 (0.017/0.042in).
Rotate the impeller to ensure free movement.
10 Put a bead of POWERPART Gasket and flange sealant on the contact surface of the pressed steel cover
(E2). Ensure that the cover is square with the body of the pump and use a suitable adaptor to press the cover
until the edge of the cover is fully onto the flange of the coolant pump body.
11 Fit the two studs to the pump.
