At the back of the pump housing, position the
(new) bearing in the bore. Place a suitable bush
(A) against the outer ring (B) of the bearing. The
outer diameter of the bush (A) must be 109 ±1
mm (4.29 ±0.04 in). Use a plastic hammer to
gently drive in the bearing, until it is in its end
position against the edge in the pump housing.

From the back side of the pump housing, use
circlip pliers to install the circlip (A) in the groove
of the pump housing (B).

Slightly grease the sealing lip of the (new)
dynamic seal (A). Do not grease the outside
surface of the dynamic seal. Fit the dynamic
seal from the front side in the pump housing,
using good engineering practices. The seal ring
must be fitted in the correct orientation. Make
sure that the open side points towards the pump
cover.

Slightly lubricate the contact surface of the inner
ring of the bearing (A) and the pump shaft (B).
