How do you adjust the pinion rotating torque on the R22T steering rack?

Set gears to Neutral, loosen the lock nut, tighten the adjusting screw one or two times to 4.9 N·m (50 kg-cm, 43 in-lb), rotate the pinion to move the rack back and forth twice and return to Neutral, loosen and retighten the adjusting screw to 5.4 N·m (55 kg-cm, 48 in-lb), back the screw off 40° to 50°, then tighten the lock nut to specified torque while holding the adjusting screw.

What special tool is used for the R22T adjusting screw torque?

Tool ST3127S000 (See J25765-A) is shown for tightening the adjusting screw.

How is the average pinion rotating torque value calculated?

The chart shows: Average value = (Max. value + Min. value) x 0.5.

What should you watch for when installing the snap ring cap?

Pay attention to the direction of the snap ring cap — the diagram distinguishes the oil seal side from the snap ring side.

This is a page from a Nissan service manual covering assembly and adjustment of the R22T manual steering gear (rack and pinion) and linkage, page ST-9. It continues the assembly procedure: step 5 covers installing the snap ring, snap ring cap and oil seal, with a diagram showing correct orientation (oil seal side vs. snap ring side, illustration SST554A). Step 6 covers installing the retainer, retainer spring, adjusting screw and lock nut (SST555A). Step 7 details the pinion rotating torque adjustment: set gears to Neutral, loosen the lock nut, tighten the adjusting screw to 4.9 N·m (50 kg-cm, 43 in-lb) using tool ST3127S000 (see J25765-A), rotate the pinion to move the rack back and forth twice, retighten the adjusting screw to 5.4 N·m (55 kg-cm, 48 in-lb), back it off 40° to 50°, then tighten the lock nut while holding the adjusting screw. Step 8 gives pinion rotating torque specifications: average value 1.0-1.4 N·m (10-14 kg-cm, 8.7-12.2 in-lb), maximum allowable 1.5 N·m (15 kg-cm, 13 in-lb), minimum allowable 0.3 N·m (3 kg-cm, 2.6 in-lb), with a chart illustrating that average value equals (max + min) x 0.5.
