Figure 22 Adjust the axial play
BC-0053-A
1. Put the pump in the horizontal posion on the foam.
2. Insert the 13 mm he
x socket wrench. Insert the T-bar through the wrench into the
headless screw of the axial limiter.
3. Hold the socket wrench and turn the T-bar clockwise. Every full turn clockwise
reduces the axial play by 0.5 mm.
4. Turn the T-bar carefully and check the axial play several mes to a
void pushing the
headless screw on block. Put the pump each me in the upright posion when you
check the axial play.
The bearing is embedded in O-rings. Therefore the axial play must be measured in
upright posion. The axial play must be in the range of
- 0.04 to 0.06 mm for the nEXT730/930D or
- 0.035 to 0.055 mm for the nEXT1230H.
