Category: Propeller Shaft And Differential Carrier

Datsun 1200 used two types of Propeller Shaft, the early type with replaceable U-joints and the later version with non-replaceable joints. The propeller shaft is commonly called the "driveshaft" or "tailshaft".

Top: Flange end, which bolts to the differential. Nissan calls this the "Flange Yoke"

Bottom: Sleeve Yoke end (aka Slip Yoke), which slips into the tail of the transmission

Datsun 1200 used two types of Propeller Shaft:

If your tailshaft has snap rings (C-shaped circlips) holding the U-joints in, they may or may not be "replaceable". Special U-joints are available for "non-replaceable" shafts.

Automatic driveshaft/tailshaft assembly differs from Manual Transmission. Automatic transmissions are 15mm shorter than a standard transmission, so the automatic shaft slip yoke is 15mm longer. The slip yoke is the part that is different. The shaft and rear flange are identical for the two different length shafts.

Interchange

* B210 with H145 Differential uses the same tailshaft
* B210 with H150 diff use different shaft
* B120 with H165 differential (PB210) 
  *may* be same as B310 two-piece shaft (?)
* Longbed Trucks use a 2-piece tailshaft

Dimensions

Removal

It will help to park the car on a slight downhill slope. This will prevent gearbox oil from leaking out when the shaft is removed. Or you could obtain a plug ahead of time.

Use a 12mm ring spanner on the nuts. Jam a long screwdriver in the u-joint to keep it from turning.

If necessary, use a length of pipe over the spanner to give it more leverage. It will come loose. Or you could do this using two combo wrenches interlocked to get more leverage:

Once the fasteners have been removed, use a screwdriver to work it off the differential flange. Grab the driveshaft with both hands, and pull it straight out of the transmission. Be sure to support the shaft: dropping it can unbalance it, and letting it hang off the end of the gearbox can damage the gearbox seal.

Replacement

When reinstalling, do not overtighten the nuts. They are just little M8 nuts, so a little torque is all that is required.

The Haynes Repair manual says:

The propeller shaft is carefully balanced to fine limits and it is important that it is replaced in exactly the same position it was prior to removal. Scratch marks on the propeller shaft and rear axle flanges to ensure accurate mating when the time comes for reassembly.

This is stock wording that's in all the Haynes manuals, even though Datsun already have a precision balanced shaft.
