Toyota Yaris: Clutch Unit / Installation
INSTALLATION
CAUTION / NOTICE / HINT
NOTICE:
When the manual transaxle assembly is removed, be sure to use a new clutch release cylinder with bearing assembly and new installation bolts. Removal of the manual transaxle assembly allows the compressed clutch release cylinder with bearing assembly to return to its original position. Dust from the moving section may damage the seal of the clutch release cylinder with bearing assembly, possibly causing clutch fluid leaks.

4. INSTALL CLUTCH RELEASE BEARING PLATE
| (a) Install a new clutch release bearing plate to the clutch release cylinder with bearing assembly. NOTICE: After installing the clutch release bearing plate to the clutch release cylinder with bearing assembly, check that there are no gaps. |
|
5. REMOVE CLUTCH RELEASE BLEEDER SUB-ASSEMBLY
(a) Disconnect the clutch release cylinder to bleeder tube from the clutch release bleeder sub-assembly.
(b) Remove the bolt and clutch release bleeder sub-assembly from the manual transaxle assembly.
6. INSPECT CLUTCH PIPE LINE
| (a) Using SST, apply pressure of 100 kPa (1.0 kgf/cm2, 15 psi) to the clutch pipe location shown in the illustration and confirm that pressure is maintained for 15 seconds or more. SST: 09992-00242 If the pressure drops, replace the clutch release cylinder to bleeder tube. |
|
7. INSTALL CLUTCH RELEASE BLEEDER SUB-ASSEMBLY
| (a) Temporarily tighten the clutch release cylinder to bleeder tube to the clutch release bleeder sub-assembly. |

Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested. Fuel spray is released when there is pressure in the fuel tank and the fuel-filler cap is removed too quickly.
