WINDSCREEN WIPERS AND WASHERS
Assemble
Note that the following lubricants are used during
assembly:
Shell Turbo 41 oil
Ragosine Listate grease
18. Position the brush assembly and limit switch unit
joined together by the wires. Secure with five screws.
19. Lubricate the cover bearing and saturate the cover
bearing felt washer with Shell Turbo 41 oil. Position
the armature to the cover against .he action of the
permanent magnet.
20. Lubricate the self aligning bearing with Shell Turbo
41 oil. Carefully insert the armature shaft through the
bearing. Ensure that the brushes are not
contaminated with lubricant. Push the three brushes
back to clear the commutator.
21. Seat the cover against the gearbox. Tum the cover to
align the marks shown. Fit the through bolts.
22. Fit the thrust screw or the thrust screw and locknut
as fitted.
23.
If a non-adjustable thrust screw is fitted check the
armature end-float as follows:
Position a feeler gauge between the armature shaft
and the thrust screw.
Push the armature towards the cover. End-float
should be 0·002 to 0·008 in.
In the unlikely event of adjustment being required
end-float may be increased by fitting shim
washer/washers under .the thrust screw head or
reduced by mounting the thrust screw in a lathe and
removing metal from the underside of the head.
24. If an adjustable thrust screw and locknut is fitted,
adjust the armature end-float as follows:
Slacken the locknut. Screw the thrust screw in until
resistance is felt. Screw the thrust screw out a quarter
of a turn - maintain in this position and tighten the
locknut.
25. Note that the final gear is serviced only as an
assembly. Normally the crankpin mounting plate is
not separated from the moulded gearwheel. If they
should become parted assemble so that the
relationship of the crankpin to the cam is as shown.
26. Lubricate the final gear bushes with Shell Turbo 41
oil. Lubricate the final gear cam with Ragosine
Listate grease. Fit the dished washer with its concave
surface facing the final gear. Insert the shaft. Fit the
washer. Fit the spring clip by inserting sideways.
27. Pack Ragosine Listate grease around the worm gear,
final gear and into the crosshead guide channel.
28. Perform 84.15.12 instructions 12 to 18.
