AT-130 AUTOMATIC TRANSMISSION — Installation of Component Parts (c) Using vernier calipers, measure the distance between the sun gear input drum and direct clutch drum as shown in the figure. Height: 9.8 — 11.8 mm (0.386 — 0.465 in.) If the values are nonstandard, check for an improper installation. (d) Coat the assembled bearing and race with petroleum jelly and install it onto the forward clutch. HINT: Assembled bearing and race diameter mm (in.) Inside Outside Bearing and Race 33.7 (1.327) 47.6 (1.874) 18. INSTALL SECOND COAST BRAKE COVER, PISTON ASSEMBLY AND SPRING (a) Coat two new O-rings with ATF and install them to the cover.

CHECK PISTON ROD STROKE OF SECOND COAST BRAKE (a) Place a mark on the second coast brake piston rod as shown in the figure. (b) Using SST, measure the stroke applying the compressed air (4 — 8 kg/cm², 57 — 114 psi or 392 — 785 kPa) as shown in the figure. SST 09240-00020 Piston rod stroke: 1.5 — 3.0 mm (0.059 — 0.118 in.) If it is still more than standard value, replace the brake band with a new one.
