Automatic Transaxle - Overhaul (FS5A-EL): Other Mazda 3 BL

Cleaning Notes

1. Clean the transaxle exterior thoroughly with steam, cleaning solvents, or both, before disassembly. WARNING: Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air.
2. Clean the removed parts with cleaning solvent, and dry with compressed air. Clean out all holes and passages with compressed air, and verify that there are no obstructions.

General notes

1. The oil pan could contain small chips, shavings, and other particles which may be helpful in inspecting the condition of the transaxle and diagnosing certain problems. To ensure that all foreign particles stay in the oil pan, make sure that the transaxle is never tipped completely over while the oil pan is still installed. Disassemble the transaxle in a clean area (dustproof work space) to prevent entry of dust into the mechanisms. Inspect the individual transaxle components in accordance with the QUICK DIAGNOSIS CHART during disassembly. Use only plastic hammers when applying force to separate the light alloy case joints. Never use rags during disassembly; they may leave particles that can clog fluid passage. Several parts resemble one another; arrange them so that they do not get mixed up. Disassemble the control valve component and thoroughly clean it when the clutch or brake band has burned or when the ATF has degenerated. WARNING: Although the stand has a self-locking brake system, there is a possibility that the brake may not hold when the transaxle is held in a lopsided position on the stand. This would cause the transaxle to turn suddenly, causing serious injury. Never keep the transaxle tilted to one side. Always hold the rotating handle firmly when turning the transaxle.

5. Release the compressed air and read the dial gauge when the direct clutch piston is not operating.
6. Calculate the direct clutch clearance according to the following formula: step (4) value - step (5) value = direct clutch clearance.
7. 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. Direct clutch clearance Standard: 1.10-1.40 mm {0.043-0.055 in}
8. If not as specified, replace parts as necessary. (See «DIRECT CLUTCH DISASSEMBLY/ASSEMBLY»(ref-345239-S10232402322009102000000) .)

Scheme 914

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 brake operation by applying compressed air as shown. Air pressure 392 kPa {4.0 kgf/cm 2 , 57 psi} max.
3. If not as specified, replace parts as necessary. (See «REDUCTION BRAKE DISASSEMBLY/ASSEMBLY»(ref-345239-S35528019482009102000000) .)

Brake clearance

Measure the reduction brake clearance.

Scheme 915

Scheme 916

Scheme 917

1. Set the dial gauge to the reduction brake.
2. Set the measuring point of the dial gauge to the retaining plate.
3. Apply compressed air to the part indicated in the figure and let the reduction brake piston stroke three times. Air pressure 392 kPa {4.0 kgf/cm 2 , 57 psi} max.
4. Apply compressed air and operate the reduction brake piston. Read the value when the indicator of the dial gauge stops.
5. Release the compressed air and read the dial gauge when the reduction brake piston is not operating.
6. Calculate the reduction brake clearance according to the following formula: Step (4) value-Step (5) value= reduction brake clearance.
7. 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. Reduction brake clearance 1.50-1.80 mm {0.059-0.070 in}
8. If not as specified, replace parts as necessary. (See «REDUCTION BRAKE DISASSEMBLY/ASSEMBLY»(ref-345239-S35528019482009102000000) .)

Differential Preinspection Backlash

Scheme 918

1. Measure the backlash of the side gear. Differential backlash Standard: 0.05-0.15 mm {0.002-0.005 in} Maximum: 0.5 mm {0.020 in}
2. If not specified, replace the differential. (See «DIFFERENTIAL DISASSEMBLY/ ASSEMBLY»(ref-345239-S32641026962009102000000) .)
