Proceed as follows to set the axial clearance:

1.Un-tighten tap bolts (0040) crosswise and remove them.

2.Use two tap bolts (0040) in the threaded holes in the pump cover (4000) to push off the pump cover (4000)

3.Take idler (0600) complete with bearing bush off the idler pin.

4.Remove O-ring (8120), support ring (8110) and shim (8100) from the pump cover (4000).

5.Check that the contact faces and O-ring chamber are not damaged and free of dirt. Check the condition of O-ring (8120), in case of doubt replace the O-ring with a new one.

6.Measure the distances as indicated on the sketch below

7.Calculate the required thickness of the shim (8100) between pump cover (4000) and pump casing (0010).

S = A – B + C. Axial clearance C between rotor shaft (0701) and pump cover (4000) see table below.

TG MAG	Axial clearance C
	[mm]
15-50	0.120 – 0.200
23-65	0.125 – 0.215
58-80	0.150 – 0.250
86-100	0.165 – 0.275
185-125	0.190 - 0.320

8.Adjust the thickness of shim (8100) by peeling off the required number of layers

9.Place shim (8100), support ring (8110) and O-ring (8120) on the pump cover (4000).

10.Place idler (0600) complete with bearing bush on the idler pin.

11.Mount pump cover (4000) on the pump casing (0010).

12.Screw in tap bolts (0040) and tighten them crosswise to fix the pump cover (4000) on the pump casing (0010).
