Checking Secondary Shaft Clearances — 1990-91 Accord, 1988-91 Prelude (Honda Accord 3)

Before disassembling the secondary shaft, the following measurements should be taken. If any dimensions are outside the tolerance limits, the entire unit should be disassembled and the non-compliant parts replaced.

If all dimensions comply with tolerances, then the secondary shaft should be disassembled only in the event of mechanical damage to any of its parts.

1. Clamp the secondary shaft assembly into the chuck, placing 2 wooden sticks to protect the shaft surface.

2. Tighten the lock nut to 110 Nm, loosen it and tighten it again to 110 Nm.

3. Measure the clearance between the 1st gear pinion and the thrust washer. The tolerance is 0.04-0.18 mm. If the tolerance is not met, then the secondary shaft unit should be disassembled and a thrust washer should be selected so that the clearance satisfies the tolerance.

4. Measure the clearance between the 3rd and 2nd gears. The tolerance is 0.03-0.18 mm. If the tolerance is not met, then the secondary shaft unit should be disassembled and a bushing-gasket should be selected so that the clearance satisfies the tolerance.
