What is the total turning torque specification for the transmission with a new bearing?

Total turning torque with a new bearing is 2.5 - 5.9 N·m (25 - 60 kg-cm, 22 - 52 in-lb). When an old bearing is reused, preload will be slightly lower; check that it is not far from the specified range.

How do you select the correct reverse check plunger?

Shift the gear position to 4th, measure the distance 'ℓ' between the transmission case and the striking interlock (neutral position), then select a suitable plunger. Refer to S.D.S. for reverse check plunger specifications.

What should be applied to the threads of the check plugs during reassembly?

Apply sealant to the threads of the plugs when installing the shift check, reverse check and 5th check component parts.

What special tool is used to measure total turning torque?

The illustration shows tool KV38106100 being used to measure total turning torque.

What is checked after the transmission is assembled?

After assembly, check that you can shift into each gear smoothly, then measure total turning torque.

This is page MT-25 from a Nissan factory service manual, covering the final steps (14–20) of manual transmission reassembly. Step 14 shows installation of the reverse bracket assembly and guide plate (illustration SMT930). Steps 15–16 cover installing the transmission case and position switch (SMT931). Step 17 covers installing the shift check, reverse check and 5th check component parts, noting to apply sealant to plug threads, with a note that certain parts are for 5-speed transmissions only (SMT882). Step 18 instructs shifting to 4th gear and measuring distance 'ℓ' between the transmission case and striking interlock (in neutral position) to select a suitable reverse check plunger, referring to S.D.S. for specifications (SMT963). Step 19 requires verifying smooth shifting into each gear after assembly. Step 20 covers measuring total turning torque using tool KV38106100 (SMT934), with a specification for new bearings of 2.5–5.9 N·m (25–60 kg-cm, 22–52 in-lb). A note explains that when an old bearing is reused, preload will be slightly lower and should be checked against the specified range.
