Mounting inductive proximity switch
Sequence:
1. Mount the inductive proximity switch Pos. 1 (see Fig.6), with
the connector on the cable end, to the side frame Pos. 4 of
the splash guard housing.
2. The two other inductive proximity switches Pos. 2 should be
mounted on the upper longitudinal member Pos. 3. To this
end use a suitable toothed disk and hexagon nut.
3. In order to ensure that the inductive proximity switches
function perfectly, they must be configured before the faste-
ning nuts are tightened.
To do so connect the splash guard doors and set the
inductive proximity switches such that the air gap X (see
Fig. 6) between the head of the proximity switch and the
contact screws (hexagon bolts) on the splash guard doors is
1.5mm (or 0.6inch). A gage block or feeler gage can be used
to help.
4. Following this, tighten the fastening nuts of the inductive
proximity switches.
! ! ! ! ! Do not overtighten the fastening nuts as this could
damage the proximity switch.

5. Mount the distributor box Pos.5 (see Fig. 7) to the angle
bracket Pos.6. To do so, remove the lid and fasten the
distributor box to the locating panel using two screws.
6. Mount the distributor box with the angle bracket to the longitu-
dinal member Pos. 3 and then connect the proximity switches
as described in Chapter 4.2 and then fit the lid back on.

Installation of overflow control valve
3.4.1 Set bore for overflow control valve
Sequence:
1. Remove side covers from the test bench.
2. Cover test-oil tank carefully. This is to ensure that no metal
filings can fall into the tank.
3. Mark the bore positions on the test bench using the following
drawing.

4. Use a hand-held power drill and suitable drill bit to bore the
d1 and d2 holes in the test bench frame.
! ! ! ! ! Make sure that when you break through with a twist drill
or center bit that the hydraulic hoses are not damaged.
5. Deburr the bores.
6. Carefully remove any metal filings left over from the test
bench.
