7.4 Manual transmission<br />
Testing<br />
5.8a Disconnect the wiring . . .<br />
1 Ensure the ignition switch is ‘OFF’.<br />
2 Unplug the wiring harness from the<br />
reversing lamp switch at the connector. The<br />
switch is threaded into the transmission<br />
casing, at the front of the unit on 085 5 speed<br />
transmissions, and at the rear of the unit on<br />
084 4 speed transmissions.<br />
3 Connect the probes of a continuity tester,<br />
or multimeter set to the resistance<br />
measurement function, across the terminals<br />
of the reverse lamp switch.<br />
4 The switch contacts are normally open, so<br />
with any gear other than reverse selected, the<br />
tester/meter should indicate an open circuit.<br />
When reverse gear is then selected, the<br />
switch contacts should close, causing the<br />
tester/meter to indicate a short circuit.<br />
5.8b . . . and remove the reversing light<br />
switch (4 speed transmission shown)<br />
5 If the switch appears to be constantly open<br />
or short circuit, or is intermittent in its<br />
operation, it should be renewed.<br />
Removal<br />
6 Ensure that the ignition switch is turned to<br />
the ‘OFF’ position.<br />
7 Unplug the wiring harness from the<br />
reversing lamp switch at the connector.<br />
8 Slacken the switch body using a ring<br />
spanner and withdraw it from the transmission.<br />
Recover the sealing ring. (see illustrations).<br />
Refitting<br />
9 Refitting is a reversal of removal.<br />
Removal<br />
1 Trace the speedometer drive cable back to<br />
the connection point on the differential<br />
6.2 Speedometer drive cable locknut<br />
(arrowed) at the differential casing<br />
housing, at the rear of the transmission<br />
casing.<br />
2 Unscrew the locknut and withdraw the end<br />
of the drive cable (see illustration). Where<br />
fitted, recover the washer.<br />
3 Using a ring spanner, unscrew and<br />
withdraw the speedometer drive guide sleeve.<br />
4 Remove the drive shaft and gear from the<br />
transmission casing.<br />
5 Clean the gear thoroughly and examine the<br />
teeth for signs of wear or damage. Renew the<br />
component if necessary, but bear in mind that<br />
the drive pinion inside the differential casing<br />
may be worn as well and this can only be<br />
renewed as part of a complete transmission<br />
overhaul.<br />
