New 1000 Series
5 A tool (A) can be made to press the coolant seal
into position. The tool should be made of a suitable
material to the dimensions listed below:
A 44,0 mm (1.73 in)
B 40,0 mm (1.57 in)
C 11,6 mm (0.46 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.
6 Turn the pump over and support the drive end of the
body. Do not lubricate the coolant seal (B4). 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. 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.
7 Hold the pump with the drive end of the shaft on a
suitable support. With the use of a suitable distance
piece and a flat bar, press the new impeller (B3) onto
the shaft until the front face of the impeller is 6,7/7,0
mm (0.26/0.28 in) below the front face of the pump
body (B1). Remove the flat bar and distance piece
and ensure that the shaft is free to rotate.
8 Clean the threads in the front face of the pump
body. Fit a new joint (B6) and the cover (B5). Fit the
setscrews and tighten them to 9 Nm (6 lbf ft) 0,9 kgf
m. If the setscrews are new, a sealant will have been
applied to the threads by the manufacturer. If the
original setscrews are to be used again, the threads
should be cleaned and a POWERPART Nutlock
applied.
9 Fit a new "O" ring (B2) to the body of the pump.
