To assemble
1 Ensure that the shaft and the seal counter bore in the pump housing are clean.
2 Fit the bearing (A1), the spacer if relevant, and the second bearing (A2) to the shaft (A16).
3 Fit the retainer (A7) and gear (A8) to the shaft assembly. Fit the second retainer (A3) and the bolt (A4).
4 Fit a new lip-type seal (A12) into the housing (A10). The seal must be fitted with the lip toward the inside of
the housing. Apply a small amount of clean engine oil to the lip of the seal.
5 Fit a new 'O' ring seal (A9) to the housing.
6 Install the gear and shaft assembly in the housing. Fit the bolts (A6) which hold the retainer (A7) to the
housing.
Caution: Do not allow grease or oil to contact the faces of the seal. Do not stretch the seal during installation.
Note: The carbon seal assembly (A13) must rotate with the coolant pump shaft when it is installed. Use clean
water as a lubricant for assistance during installation.
7 Separate the spring from the seal assembly (A13). Use hand pressure to install the seal on the shaft (A16).
Push the seal onto the shaft until the seal faces make light contact. Fit the spring to the shaft.
8 Fit the impeller (A11) to the shaft and retain with the washer (A14) and bolt (A15). Tighten the bolt to a torque
of 39 +/- 3 Nm (28 +/- 2 lbf ft).
