Secondary Shaft 2nd Gear Clearance Inspection

NOTE: The illustration shows the K20A4 and K20A5 engine models; the K24A1 engine model is similar.

1.Install the thrust needle bearing (A), needle bearing (B), 2nd gear (C), thrust needle bearing (D), 37 x 58 mm thrust washer (E), and 2nd clutch (F) on the secondary shaft (G), then secure them with the snap ring (H).

 

2.Measure the clearance between the snap ring (A) and the 2nd clutch guide (B) with a feeler gauge (C), in at least three places. Use the average as the actual clearance.

STANDARD:  0.04-0.12 mm (0.002-0.005 in.) 

 

 

3.If the clearance is out of standard, remove the 37 x 58 mm thrust washer and measure its thickness.

4.Select and install a new thrust washer, then recheck.
