(a) Place the direct clutch assembly onto the O/D support assembly.

SST

AT8493

(b) Using SST and a dial indicator, measure the direct clutch pack clearance while applying and releasing compressed air (186-206 kPa, 1.9-2.1 kgf/cm2, 27-30 psi).
SST 09350-30020 (09350-06120)
Pack clearance:
0.50 - 0.80 mm (0.0197 - 0.0315 in.)
If the pack clearance is less than the limit, parts may have been assembled incorrectly, so check and reassemble again.
If the pack clearance is non-standard, select another flange.
HINT: There are 9 different flange thicknesses.
