-	= Speedometer Calibration =	+	For calibration, the MPH speedo is marked in KPH ranges on the very edge, which are partly visible when installed.
-	There are two basic reasons for speedos reading fast or slow:	+	<br>{{Album|13742}}
-	# Factory speedometer tolerance is usually 5% fast to 10% slow (this is in general, I don't know what Nissan's specs are)	+
-	#: [http://datsun1200.com/modules/newbb/viewtopic.php?topic_id=13971&forum=1 1200 Top Speed] discusses this. One magazine test noted the 1200 speedometer in the test car was 7% slow. My 1200s have been between 7.5% - 10% slow (with stock running gear include tire size). Also see [http://datsun1200.com/modules/myalbum/photo.php?lid=2028 speedo off]	+
-	# Different size tires than original, changed diff ratio or transmission	+
-	For the latter, there is a mechanical solution of changing to the appropriate speedo-drive gear at the back of the transmission:	+	[[Meter_Part_Numbers#USA|24850-H1816]] 100MPH w/o tripmeter (AUS/USA standard equipment)

-	Before messing with the mechanism, make sure the odometer (distance counter) is correct. If it is not, different transmission-to-speedometer cable pinion gears are called for.	+	<br>{{PhotoPost|1300060168_177086830_11-DATSUN-SADO-.jpg|393690|Datsun%201200/1200AX}}
-	Get on the highway and drive. As you pass the mile markers note the indicated milage. A 10 mile drive is good for accuracy. If the odometer reads 10.0 miles it is perfect. But if it read 11.0 mile it is running 10% off.	+	160 kph

-	== Changing Scale ==	+	Take the face plate and scan it on the flatbad scanner, then modify it. Finally, print a new one out with the photo printer. You can modify the font, colors, etc. You might think you can simply bolt it to the speedo using the standard screws, but it will not lay flat. Adhesive paper (sticker paper) will work
-	You can easily change the scale to make it read correctly, or to make a 180 kph scale. The downside is that the odometer (distance counter) will be inaccurate.	+	<br>{{Album|15393}}

-	* Scale Adjusted for low gearing, looks good printed on photo paper and bolted to speedometer.	+	It is normal for the speedometer '''to read fast'''. The specified tolerance is +5% -10%. So at actual 60mph it can read 57 to 66 and still be acceptable. But you can blueprint the speedometer to be closer to the actual speed.
-	* Use a light, removable contact cement. Otherwise if you just tack the edges or a places, the photo will eventually buckle and warp and interfere with the needle movement.	+
-	* I modified mine to change the scale since I didn't want to get under the car and change the plastic speedo gears.	+

-	Given that stock is a 17 tooth pinion, moving to one more or less tooth is about 6% change. So by changing the pinion you can only get it to ±3 mph accurate. For example, at 100 mph, within 3 mph. Or at the standard 50 mph rating, a reading between 1½ mph (48½ to 51½) is the best you can hope for. For finer tuning the speedometer itself needs calibration. Or you could fit different diameter rear tires.	+	350Z speedometer looks a similar size.
		+	<br>{{Album|14499}}
-	EXAMPLE: If you are reading say 60 when you are really going 50 then the speedo cable needs to slow down by about 20% to read more accurately. If the speedo drive has a 17 tooth cog in it try to find a cog that reduces by 20%. 17 X .20 = 3.4 teeth... 17 + 3.4 = 20.4 teeth, the closest is a 20 tooth cog.	+	== Electronic Speedometer ==
		+	Yes, you can fit an electronic speedometer into a 1200.

Current revision

Speedometers were either in kilometers or miles. Australia started with mph and then switched to kph via sticker overlays. Some speedometers had a trip meter.

Variations

STD bar gauge

STD speedometer was a rectangular type (GL & GX used round gauges as did all coupes). DX varied: Mostly rectangular, but USA Deluxe had round gauges.

Facelift GX

Gauges changed for the 1972 minor facelift in Japan. As before the GX speedometer went to 180km/h instead of the regular 160km/h. As with all 1972s it had the speed warning sensor.

Metric-Imperial Conversion

Sometimes on eBay Australia you can get the vintage conversion stickers.
Album 923 Album 5362

OR

print this on plain paper at 125%, for a test fit. If you like it, print on sticker stock then apply to the speedometer
Album 1101

OR

Take the face plate and scan it on the flatbad scanner, then modify it. Finally, print a new one out with the photo printer. You can modify the font, colors, etc. You might think you can simply bolt it to the speedo using the standard screws, but it will not lay flat. Adhesive paper (sticker paper) will work
Album 15393

Speedometer Calibration

It is normal for the speedometer to read fast. The specified tolerance is +5% -10%. So at actual 60mph it can read 57 to 66 and still be acceptable. But you can blueprint the speedometer to be closer to the actual speed.

Speed Buzzer

Starting in 1972, all JDM speedometer came with speed switch for warning of excess velocity.

Amplifier Speed Switch

1972 Japan, Australia late utes and 1973 USA used a speed switch.

Custom Faces

Z Speedometer

280Z speedometer fits in the 1200 dash cluster.

1. Swap the mounting cups as the 280Z unit is deeper
2. Drill a hole for the trip meter shaft through the back
3. The face is to large for the opening in the 1200 housing, so carefully reduce the diameter by 1/8 inch

350Z speedometer looks a similar size.

Electronic Speedometer

Yes, you can fit an electronic speedometer into a 1200.
