Title: EC65 (MANUAL TRANSMISSION / TRANSAXLE): MANUAL TRANSAXLE ASSEMBLY: REMOVAL; 2023 MY Corolla Corolla Hatchback [09/2022 - 11/2022]

REMOVAL

CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during manual transaxle assembly removal/installation are shown below.

Necessary Procedures After Parts Removed/Installed/Replaced

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
*1: w/o Smart Key System
Replacement of ECM	Vehicle Identification Number (VIN) registration	MIL comes on
Replacement of ECM	ECU communication ID registration (Immobiliser system)	Engine start function
Gas leak from exhaust system is repaired	Inspection after repair	Poor idle, etc. Engine start function, etc.
Replacement of ECM*1	Code registration (Immobiliser system)	Engine start Telematics System

CAUTION:

To prevent burns, do not touch the engine, exhaust pipe or other high temperature components while the engine is hot.

The manual transaxle assembly is very heavy. Be sure to follow the procedure described in the repair manual, or the transmission jack may suddenly drop.

*a	An Object Exceeding Weight Limit of Transmission Jack

If work is not performed according to the procedures described in the repair manual, there is a danger that the transmission jack could drop and components could fall down.

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.

HINT:

When the cable is disconnected / reconnected to the battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

Learning completes when vehicle is driven

(b) Remove the 2 bolts to separate the No. 3 radiator hose from the fan shroud.

*a	Support Shaft	*b	Front Side Member
*c	Nut	*d	Cloth

SST: 09940-10020

CAUTION:

Make sure that no oil or grease is on the front side member, and set the support shaft on the level surface of the front side member.

*a	Support Shaft
*b	Front Side Member

The engine support bridge may fall off if any oil or grease is still on or it is installed on the unlevel surface.

NOTICE:

Prevent SST from contacting the vehicle body exterior and windshield glass.
To prevent damage to the engine hood, place pieces of cloth between the engine hood and SST.
Lightly shake SST by hand to make sure it is securely installed before performing work.

(d) Turn the threaded portion of each support shaft to adjust its height until the sub beams are parallel to the ground.

*a	Support Shaft
*b	Sub Beam
*c	Front Side Member
*d	Threaded Portion

(e) Install the chain block assembly to the sling bracket.

*a	Chain Block Assembly	*b	Sling Bracket
*c	Fuse Shackle	-	-

(f) Install the division bar to the chain block assembly with the shackle (A).

CAUTION:

Make sure the fuse shackle is on the chain block assembly side and the shackle (A) is on the division bar side as shown in the illustration so that the fuse bolt is visible and can be checked for deformation easily.

*a	Fuse Shackle
*b	Shackle (A)

If the fuse shackle is installed upside down, deformation of the fuse bolt will not be visible and cannot be used to tell if the load capacity of the engine support bridge has been exceeded. If the load capacity is exceeded, it may cause the engine support bridge to damage the vehicle and the engine assembly with transaxle assembly may fall.

Make sure that the fuse bolt of the fuse shackle is free of damage, such as deformation or cracks. If damaged, replace the fuse shackle.

*a	Fuse Shackle
*b	Fuse Bolt

If a deformed fuse bolt is used, it cannot be used to tell if the load capacity of the engine support bridge has been exceeded. If the load capacity is exceeded, it may cause the engine support bridge to damage the vehicle and the engine assembly with transaxle assembly may fall.

(g) Connect the division bar to the No. 1 engine hanger with the shackle (B).

*1	No. 1 Engine Hanger	*2	No. 2 Engine Hanger
*a	Division Bar	*b	Shackle (B)
*c	Chain	*d	Shackle (A)

(h) Connect the division bar to the No. 2 engine hanger with the shackle (A) and chain.

NOTICE:

Connect the 2nd link of the chain to the No. 2 engine hanger.

(i) Make sure the distance between the chain block assembly and suspension ring is 120 mm (4.72 in.) or more.

HINT:

If the suspension height is less than 120 mm, adjust the links of the chain which connect the division bar and engine hanger.

*a	120 mm (4.72 in.) or more

(j) Adjust the positions of the chain block assembly, support brackets and main beam so that the chain of the chain block assembly is perpendicular to the main beam and the length of the main beam on the outer side of the support bracket LH and RH is the same as shown in the illustration.

*a	Chain Block Assembly	*b	Main Beam
*c	Dimension (A)	*d	Dimension (B)
*e	Right to Left Adjustment	*f	Front to Rear Adjustment

CAUTION:

To prevent the engine assembly with transaxle assembly from falling, make sure that the length of dimension (A) and dimension (B) are equal.

*a	Main Beam
*b	Sub Beam
*c	Dimension (A)
*d	Dimension (B)

Do not perform any procedures if the length of dimension (A) and dimension (B) are not equal.
Performing any procedure when the length of dimension (A) and dimension (B) are not equal may cause the engine assembly with transaxle assembly and engine support bridge to fall, possibly causing serious injury.

NOTICE:

Do not perform any procedures if the chain of the chain block assembly is not straight.
When removing the engine mount, if the chain of the chain block assembly is not straight, the engine assembly or transaxle assembly may contact the vehicle body.

(k) Confirm the appropriate installation state of the engine support bridge and tighten the 6 wing bolts and 2 bolts.

Torque:

Bolt :

30 N·m {306 kgf·cm, 22 ft·lbf}

CAUTION:

Do not perform any procedures before tightening the bolts to the specified torque.
Performing procedures without tightening the bolts to the specified torque, may cause the engine support bridge to fall.

(l) Tighten the chain block assembly until it cannot be moved any further by hand.

Turn

*a	41 Nm (418 kgfcm, 30 ft.*lbf) or more

When suspending the engine with automatic transaxle assembly, do not tighten the chain block assembly more than 41 N*m (418 kgf*cm, 30 ft.*lbf).
Tightening the chain block assembly more than 41 N*m (418 kgf*cm, 30 ft.*lbf) will cause the load capacity (400 kg (881.8 lb)) to be exceeded and may cause damage to the engine support bridge and vehicle body.
