Total End Play Measurement/Adjustment
TOTAL END PLAY MEASUREMENT/ADJUSTMENTCAUTION:
- The total end play is the play (gap) in the axial direction of each planetary gear.
- If the total end play adjustment is not performed, it may cause damage to the thrust needle bearing between each planetary gear or other parts. Accurately perform the following servicing.
Preparation Before Servicing
1. Print out the measurement/adjustment value input sheet. (See MEASUREMENT/ADJUSTMENT VALUE INPUT SHEET.)
NOTE:
- When performing the measurement/adjustment, input the measured and calculated values into the measurement/adjustment value input sheet.
- When performing the other measurements/adjustments, if the measurement/adjustment value input sheet has been printed out, use the printed sheet.
Total End Play Measurement/Adjustment
1. Rotate and adjust the rotation handle of the engine stand so that the end cover side is facing upward.
CAUTION: To reduce error during the total end play measurement, adjust so that the alignment surface of the transaxle case with the end cover is level.
2. Remove any remaining old sealant on the contact surfaces of the transaxle case and end cover.
3. Assemble the shim (FZ01 19 2L1) for the total end play measurement/adjustment.
4. Assemble the end cover component.
NOTE: Adjust the oil pipe and assemble the end cover component so that the oil pipe is assembled to the end cover oil passage.
A : End cover oil passage
B : Oil pipe
5. Place a 98-196 N {10.0-19.9 kgf, 23.0-44.0 lbf} weight on the end cover.
A : Weight (V-block)
NOTE:
- Use a V-block as a weight.
- To reduce error during the total end play measurement, place the weight near the center of the end cover.
6. Measure the total end play adjustment value using the following procedure:
NOTE:
- The total end play adjustment value is the gap between the transaxle case and end cover with the shim (FZ01 19 2L1) for the total end play measurement/adjustment assembled.
- Recommended measuring instrument: Thickness gauge
1. Measure the total end play adjustment value (gap between the transaxle case and end cover) in four locations (each separated by 90°) and calculate the average of the total end play adjustment value.
A : Total end play adjustment value
B : End cover end (alignment surface with transaxle case)
C : Transaxle case end (alignment surface with end cover)
2. Input the measured total end play adjustment value and calculated average of the total end play adjustment value into the measurement/adjustment value sheet.
7. Remove the weight on the end cover.
A : Weight (V-block)
8. Remove the end cover component.
9. Remove the shim (FZ01 19 2L1) for the total end play measurement/adjustment.
10. Measure the thickness of the removed shim (FZ01 19 2L1) for the total end play measurement/adjustment.
NOTE: Recommended measuring instrument: Micrometer
11. Input the measured shim thickness into the measurement/adjustment value sheet.
12. Select the appropriate shim from the following table.
Range = B + C
B : Average adjustment of total end play
C : Thickness of shim (FZ01 19 2L1) for total end play measurement/adjustment
Note
Example
B : If the average of total end play adjustment value is 0.115 mm {0.00453 in}
C : If the thickness of the shim (FZ01 19 2L1) for the total end play measurement/adjustment is 3.010 mm {0.11850 in}
Range = 0.115 mm {0.00453 in} + 3.010 mm {0.11850 in} = 3.125 mm {0.12303 in}, the selected shim has a thickness of 2.5 mm {0.098 in}.
