AT-86 AUTOMATIC TRANSMISSION — Component Parts (Direct Clutch) [DIAGRAM: SST tool with direct clutch assembly - D4822] (b) Using SST and a dial indicator, measure the direct clutch piston stroke applying and releasing the compressed air (4 — 8 kg/cm², 57 — 114 psi or 392 — 785 kPa) as shown. SST 09350-30020 (09350-06120) Piston stroke: 1.37 — 1.60 mm (0.0539 — 0.0630 in.) If the piston stroke is less than the limit, parts may have been assembled incorrectly, check and reassemble again. If the piston stroke is nonstandard, select another flange. HINT: There are eight different thicknesses for the flange. Flange thickness mm (in.) No. Thickness No. Thickness 33 3.0 (0.118) 29 3.4 (0.134) 32 3.1 (0.122) 28 3.5 (0.138) 31 3.2 (0.126) 27 3.6 (0.142) 30 3.3 (0.130) 26 3.7 (0.146) 5. INSTALL CLUTCH DRUM THRUST WASHER Coat the thrust washer with petroleum jelly and install it onto the direct clutch. HINT: Make sure that the lug shapes match the cutout portions on the direct clutch. [DIAGRAM: Thrust washer installation - AT1153] 6. INSTALL DIRECT CLUTCH ASSEMBLY TO FORWARD CLUTCH ASSEMBLY (a) Align the flukes of discs in the direct clutch. (b) Install the direct clutch assembly onto the forward clutch assembly. [DIAGRAM: Installing direct clutch to forward clutch - D4825] (c) Check that the distance from the direct clutch end to the forward clutch end is 71.2 mm (2.803 in.). If the distance is less than the above value, parts may have been assembled incorrectly, check and reassemble again. [DIAGRAM: Measurement of 71.2 mm distance - D4843]
