Revision as of 21:52, 7 October 2017
Left-hand-drive (LHD) versions of the Datsun 1200 used a hydraulic clutch system. It is very nice, with a light, linear action.
Contents |
Daily Care
1972 USA Owners manual (Page 25 ... ):
Before driving or whenever you call at a gas-station, be sure to check ...
- Leakage and amount of fluid in brake and clutch master cylinders
- Clutch and brake operation
Observe the level of fluid visible through the plastic reservoir of the master cylinder (no need to remove the cap).
- If it is at or below the fill line, top up with DOT 3 Brake/Clutch fluid.
Overview
Stock pedal force is 10.8 kg (23.8 lb), a bit higher than the RHD mechnical clutch at 8.3 kg (18.3 lb). The slave cylinder diameter is 3/4 inch and the master cylinder is 5/8 inch.
- Extremely light clutch pedal effort, but with good feedback
Clutch slave cylinder bolted to transmission
Adjustment
This is for the 71-73 1200. The B210 (120Y) measurements are different.
- Adjust slave cylinder free play
- Adjust pedal pad height without stopper
- Adjust pedal stopper
Clutch Slave Cylinder
Stock clutch slave cylinder diameter is 3/4 inch.
Adjust the free play to 5/32".
Pedal Linkage
Before adjusting the pedal linkage, first adjust the clutch release arm under the car.
Slave cylinder: 1 to 2 mm play. Pull the release lever until it stops.
The pedal specs are:
- Pedal height: 5.57 in (141.5 mm)
- Pedal free play: 1.181 in (30 mm)
- Pedal stroke is 5.65 in (143.5 mm) with the adjustment stop (the switch in the diagram) backed off. Adjustment is made with shims for the cylinder on the firewall.
Adusting Shim
- 30611-27260 1.6 mm
- 30612-27260 0.8 mm
- 30613-27260 0.5 mm
Removable, Replacement and Bleeding
If the Master Cylinder runs dry, or when replacing it, be sure to bleed the Master Cylinder separately.
Remove the pipe & place a thumb over it for the return stroke of the pedal to prevent ingestion of air. Once the Master Cylinder is free of air you can bleed the whole system with confidence.
Part Numbers
Stock USA cylinders. "Repair Kits" are also available. These include all new rubber parts, and can be used if the aluminum body is not pitted. The bore is hand-honed. Often with aluminum a kit will leak, so we recommend a new unit rather than a kit. Cast-iron cylinders may have better success.
