Title: CLUTCH: CLUTCH UNIT (for EC65): INSTALLATION; 2023 MY Corolla Corolla Hatchback [09/2022 - 11/2022]

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.

Temporarily Tighten

(b) Following the procedure shown in the illustration, tighten the 6 bolts in order, starting with the bolt located near the knock pin at the top.

SST: 09301-00210

Torque:

19.1 N·m {195 kgf·cm, 14 ft·lbf}

HINT:

  • Following the order in the illustration, tighten the bolts evenly one at a time.
  • Move SST up and down, right and left lightly after checking that the clutch disc assembly is in the center, and tighten the bolts.

3. INSPECT AND ADJUST CLUTCH COVER ASSEMBLY

(a) Using a dial indicator with a roller instrument, check the diaphragm spring tip alignment.

Maximum Non-alignment:

0.5 mm (0.0197 in.)

(b) If the alignment is not as specified, using SST, adjust the diaphragm spring tip alignment.

SST: 09333-00013

4. INSTALL CLUTCH RELEASE CYLINDER WITH BEARING ASSEMBLY

(a) Temporarily tighten the clutch release cylinder to bleeder tube to a new clutch release cylinder with bearing assembly.

NOTICE:

Do not allow any foreign matter such as dirt or dust to enter the clutch release cylinder to bleeder tube from the connecting part.

(b) Clean and degrease all installation surfaces for the clutch release cylinder with bearing assembly.

(c) Install the clutch release cylinder with bearing assembly with 3 new bolts.

Torque:

22.5 N·m {229 kgf·cm, 17 ft·lbf}

NOTICE:

  • The clutch release cylinder with bearing assembly and installation bolts cannot be reused and must be replaced with new ones.
  • Clean and degrease all installation surfaces and make sure that the clutch release cylinder with bearing assembly fits securely with the manual transaxle assembly during installation. The first bolt should be tightened by hand while holding the clutch release cylinder with bearing assembly.
  • Ensure that none of the clutch spline grease adheres to the clutch release cylinder with bearing assembly.
  • The clutch release cylinder with bearing assembly cannot be disassembled.

(d) Install the clutch tube boot onto the manual transaxle assembly.

(e) Temporarily tighten the clutch release cylinder to bleeder tube to the clutch release bleeder sub-assembly.

(f) Temporarily tighten the 2 bolts and install the clutch release bleeder sub-assembly.

(g) Using a 10 mm union nut wrench, install the clutch release cylinder to bleeder tube to the clutch release cylinder with bearing assembly.

Torque:

Specified Tightening Torque :

15.2 N·m {155 kgf·cm, 11 ft·lbf}

NOTICE:

Do not kink or damage the clutch release cylinder to bleeder tube.
