-The B110 uses a steering gearbox integral (one unit) with the steering column. Optionally available was a collapsible-column unit for safety in case of a crash. The collapsible column was standard for USA models. The gearbox is a relatively fast 15:1 ratio with only 3.3 turns lock to lock, and used a quality recirculating-ball type system. The only problem was a bit of play, as is common to boxes of this type, but as the years have gone by many boxes are worn out. Unfortunately no other gearbox fits and new ones are no longer available.+The B110 uses a steering gearbox integral (one unit) with the steering column.

The B210 and B310 units both have a seperate gearbox and column, joined by a flexible coupling. But these gearboxes will not bolt to the B110 subframe connection.

 +Datsun 1200 uses RB41N (Recirculating Ball) steering gear, a type which is also known as '''Worm and Sector'''. RB type is still used by fullsize cars and trucks as it is stronger/more durable than rack & pinion gearboxes.

-** Shaft Size=0.984" +<br>Datsun 1200 uses 60 ball bearings (7/32 in. size). 38 are rolling in the ball nut at any given time, while the other 22 are moving in the ball nut tubes. Ball grades 10 (best) to 50 (OK) are probably acceptible, with Grade 25 being recommended (these are about $5 per 100). Maximum axial play is 0.0031 inch -- if greater play is measured then oversize balls should be fitted.

Current revision

The B110 uses a steering gearbox integral (one unit) with the steering column. Optionally available was a collapsible-column unit for safety in case of a crash. The collapsible column was standard for USA models. The gearbox is a relatively fast 15:1 ratio with only 3.3 turns lock to lock, and used a quality recirculating-ball type system. The only problem was a bit of play, as is common to boxes of this type, but as the years have gone by many boxes are worn out. Unfortunately no other gearbox fits. New ones may be available from Nissan South Africa.

21937.jpgAlbum 21937 25282b.jpg

The B210 and B310 units both have a seperate gearbox and column, joined by a flexible coupling. But these gearboxes will not bolt to the B110 subframe connection.

  • B120: Type RB41N, 15.0:1 3.3 turns
    • Available in standard or collapsible column types
  • B210: 15.0:1 3.38+ turns
  • B310 A12: Type RB43N 16.4:1 3.5 turns
  • B310 A14/A15: Type BR45L 15.0:1 3.2 turns
  • B310 Australia uses 16.4:1 model for all engine (per Gregory's)

The steering arm is fastened to the gear by an M16 nut, with 24mm hex.

LHD vs RHD

LHD uses a mirror-image version of the RHD gearbox. The chassis side rails (front side members) appear to be drilled on both sides.

Gear

Datsun 1200 uses RB41N (Recirculating Ball) steering gear, a type which is also known as Worm and Sector. RB type is still used by fullsize cars and trucks as it is stronger/more durable than rack & pinion gearboxes.

Generic recirculating ball diagram
400px-RecirculatingBall.pngWIKI go to Wikipedia

Datsun 1200 RB gearbox. Normally the ball-nut block is not removed from the shaft.
25283.jpgAlbum 25283
Datsun 1200 uses 60 ball bearings (7/32 in. size). 38 are rolling in the ball nut at any given time, while the other 22 are moving in the ball nut tubes. Ball grades 10 (best) to 50 (OK) are probably acceptible, with Grade 25 being recommended (these are about $5 per 100). Maximum axial play is 0.0031 inch -- if greater play is measured then oversize balls should be fitted.

Interchange

Only Datsun 1200 gearbox interchanges. Made in Japan through 1994, and in South Africa through 2007.

B110 mounts with one front bolt, two rear bolts. PB110, B210, B310, 510 mount with two front bolts, single rear bolt. Cherry uses Rack & Pinion, so it does not interchange.

20920.jpgAlbum 20920

Some parts inside the gearbox, including seal and bearings, interchange between B110 RB41N and the smaller B210 (early RHD) box and the smaller B310 box -- type RB43N. B210/B310 BR45L boxes share zero parts with the B110 box.

23421.jpgAlbum 23421

Up to 1" play is normal and does not indicate a worn box. Check to see if it is worn out. Wiggle the steering wheel back and forth with your pinky. Look under the car at the same time to ensure the steering box gear arm is not moving -- if it is then you are applying too much force to the wheel for this test.

17660.jpgAlbum 17660

If the steering wheel moves up/down, that is the column bushing, easily replaceable new from Nissan.

If the steering wheel moves in/out it indicates the Steering Wheel needs to be tightened down.

Steering Column

The steering column is integrated with the gearbox; they do not come apart.

U-joints

Datsun 1200 does not use a separate steering column; it has the column as one piece (integral) with the steering gearbox.

B210 and B310 use a separate column with a rag joint.
