Revision as of 03:09, 22 March 2009
Left-hand-drive (LHD) versions of the Datsun 1200 used a hydraulic clutch system. It is very nice, with a light, linear action. 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.

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.
The 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.
Master Cylinder
Clutch Master Cylinder - 5/8"
- 30610-24900 (superceded by 30610-24910). $111 USD
- RHINO PAC M0600 $35.79
Slave Cylinder
Clutch Slave Cylinder - 3/4"
-
- Left: Original Style 30620-H1601 (superceded by 30620-H1600) $59 USD
- Right: Replacement Style 30620-H1600
Clutch Slave Cylinder
- RAYBESTOS SC37495 $12.44
- ACDELCO 18F19 $14.56
- RHINO PAC S0600 $15.92
B210
B210
- Clutch Master Cylinder: 5/8 inch
- Clutch Slave Cylinder: 11/16 inch
- Comparo: B110 and B210 are both 5/8" Master Cylinders
Beck Arnley part number 072-6489
HYDRAULIC HOSE
The hose is difficult to find in USA, except on eBay. Alternatives: lot of the brake hoses from cars with a solid rear axel will work also:
- Beck/Arnley 073-0879 (rear brake hose)
- BRAKEWARE #77001 $12 at Autozone. It's about 1.5-2 inches longer then the original, does not hang too low and bolts right up
RHD Hydraulic Conversion
Hydraulic Clutch Master
- Girling "claypipe" master cylinder, available in 5/8" and 3/4" bores (about $70 AUD). Threads are 3/8 unc for pipe outlet and 7/16 unc for fluid in
- Nissan Urvan remote-fill tops
- A simple 90-degree bracket is needed to be made up to mount this master cylinder
Nissan Sentra Clutch Master Cylinder
- Fluid reservoir is connected to the cylinder via a rubber hose.
Remote Clutch Master Cylinder
A remote clutch cylinder may also be useful
