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
|
|
|
(i) 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.

-
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.
-
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.
(j) 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.
(k) Tighten the chain block assembly until it cannot be moved any further by hand.
*a
|
41 N*m (418 kgf*cm, 30 ft.*lbf) or more
|
-
When suspending the engine assembly with 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.

48. REMOVE CVT OIL PUMP TYPE T OIL SEAL
NOTICE:
-
Do not remove the front oil pump assembly from the CVT main body, as there is a possibility of the entry of dust and foreign matter.
-
Clean the work area, the tools to be used, and other equipment, etc. thoroughly before the operation, as there is the possibility that a CVT malfunction, which could prevent the vehicle from being able to be driven, could occur if dust or fine foreign matter enters the CVT.
-
Do not use cotton work gloves, cloths, or paper towels, etc. that may produce lint, dust or foreign matter.
-
Perform the operation as quickly as possible, as dust and foreign matter could enter the CVT while the torque converter assembly is removed.
-
Do not use an air gun until the torque converter assembly has been installed, as it could cause dust and foreign matter to be stirred up.
