Disassembly
Pull out connectors and the flexible shaft, and then detach wires connected with the electronic tachometer before
removing the instrument panel assembly.
1.Remove the speedometer after detaching 3 tapping screw.
2.Pull out bulb when turning the bulb holder counter clockwise to make it aligned with the notch.
3.The voltage drop resistors of small meters are also tightened by tapping screws so that they can be removed.
4.The wire connectors of the speedometer are connected to the big case by the tapping screws and they can be
pulled out after removing the bulb holder and loosening screws. When assembling, fit lamps by passing
through the circuit board or by removing all the warning lamps first, connect wires and fit the lamps.
5.The circuit board is riveted to the case, so pull it out by force when detaching.
6.After removing the big case, the pattern pieces can be removed because they are stuck with glue which will not
dry. But they should be put in appropriate positions when assembling.
7.Remove meters after loosening screws at the back of the big case. Fit it carefully when assembling to avoid the
bad fit between transition connecting parts and the big case.
8.Take out the circuit board only after all the bulbs and screws are removed.
Instruments replacing
The speedometer and tachometer can be replaced directly after disassembling according to the above
method. The three small meters can be replaced after the transition connecting parts have been removed which
should be fit and tightened after the meters are replaced.
Reassembly and check
Reassemble the removed parts in the reverse order of removal and tighten screws when reassembling. Check
if there is any part assembled wrongly or any scratches, damages and so on. Then attach the connectors, the
tachometer wires and the flexible shaft of the speedometer. Assemble the instrument panel assembly and operate
it for a while to see if the meters work normally.
Notice
Attach connectors A and B appropriately and note if the voltage of the electric system is connected.
Stop the vehicle to check immediately if the warning indicator illuminated and something troubled
happened.
The light spring washer and washer of the small meters should be copper plated or galvanized.
Meters on the instrument panel should be matched with appropriately specified sensors.
The speedometer assembly and the big case are connected with panel by tapping screws, so please be careful
when assembling and disassembling in order to avoid damages of the tapping thread and result in loose
connecting.
