Automatic Transaxle - Overhaul (FS5A-EL): Overview Mazda 3 BM

Low and Reverse Brake Preinspection Brake operation

1. Inspect the brake operation by applying compressed air as shown. Air pressure 392 kPa {4.0 kgf/cm 2 , 57 psi} max.
2. If not as specified, replace parts as necessary. (See «LOW AND REVERSE BRAKE AND ONE-WAY CLUTCH INNER RACE DISASSEMBLY/ASSEMBLY»(ref-345239-S07193115322009102000000) .)

1. Measure the low and reverse brake clearance. Set the dial gauge to the low and reverse brake. Set the measuring point of the dial gauge to the low and reverse brake piston. Apply compressed air to the part indicated in the figure and let the low and reverse brake piston stroke three times. Air pressure 98.1 kPa {1.0 kgf/cm 2 , 14 psi} Apply compressed air and operate the low and reverse brake piston. Read the value when the indicator of the dial gauge stops. Release the compressed air and read the dial gauge when the low and reverse brake piston is not operating. Calculate the low and reverse brake clearance according to the following formula: Step (4) value - Step (5) value = low and reverse brake clearance. Measure the clearances at four locations (90° apart) by following the steps from (3) to (6). Verify that the average value is within the specification below: Low and reverse brake clearance 2.20-2.50 mm {0.087-0.098 in}
2. If not as specified, replace parts as necessary. (See «LOW AND REVERSE BRAKE AND ONE-WAY CLUTCH INNER RACE DISASSEMBLY/ASSEMBLY»(ref-345239-S07193115322009102000000) .)

Scheme 20

1. Set the one-way clutch No.2 component and direct clutch to the transaxle case. Verify that the one-way clutch rotates smoothly when turned counterclockwise and locks when turned clockwise.
2. If not as specified, replace parts as necessary.

Scheme 21

1. Set the direct clutch drum onto the transaxle case. CAUTION: Applying compressed air to the assembled clutch pack for longer than 3 s at a time will damage the seal. Do not apply compressed air for more than the aforementioned time when testing the system.
2. Inspect the clutch operation by applying compressed air as shown. Air pressure 392-441 kPa {4.0-4.5 kgf/cm 2 , 57-63 psi}
3. If not as specified, replace parts as necessary. (See «DIRECT CLUTCH DISASSEMBLY/ASSEMBLY»(ref-345239-S10232402322009102000000) .)
