Caution: Do not lubricate the coolant seal (A4). 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.
14 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.
15 A tool (B) 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)
E 16,1 mm (0.63 in)
F 1,00 mm (0.04 in) at 45°
G 2,00 mm (0.08 in) at 45°
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.
16 Ensure that the drive end of the shaft has support.
Use a suitable distance piece and a flat bar to press
the impeller (A3) 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 (A5). This dimension will
ensure an impeller clearance (A1) of 0,44/1,06
(0.017/0.042in). Rotate the impeller to ensure free
movement.
17 Put a bead of POWERPART Flange sealant,
currently Loctite 290, on the contact surface of the
pressed steel cover (A2). 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.
18 Fit the two studs to the pump.
