1987 Chevrolet Monte Carlo LS, 4.3 ZSECTION Intermediate Band Apply Pin Selection
- Install Band Apply Pin Selection Gauge (J-25014-2) in intermediate servo bore and retain with servo cover retaining ring, aligning ring with gap at case slot. Install Selection Gauge Tapered Pin (J-25014-1) into gauge. See Fig 1 .
- Ensure tapered pin end is properly located against band apply lug and band anchor pin is properly located in case and band anchor lug. If band selection tapered pin does not register between high and low limits, look for possible problem with intermediate band, direct clutch housing or transmission case.
- Install dial indicator and position indicator point on top of selection gauge post. Set indicator to zero. Ensure selection gauge is squarely seated against servo retaining ring and stepped side of tapered pin is aligned with torquing arm of gauge.
- Using torque wrench, apply 100 INCH Lbs (12 N.m.) to selection gauge torque arm. Slide dial indicator over tapered pin. Read dial indicator and see INTERMEDIATE BAND APPLY PIN SELECTION for proper pin.
NOTE:
Dial indicator travel is reversed, making indicator readings backwards. On an indicator that ranges from 0-100, a .020" (.51 mm) travel will read .080" (2.03 mm), a .060" (1.52 mm) travel will read .040" (1.02 mm).
