Removal
[2.4L Engine only]
1. | Remove the timing chain. (Refer to timing system in this group)
2. | Install a set pin after compressing the balance shaft chain tensioner.
3. | Remove the balance shaft chain hydraulic tensioner (A).
4. | Remove the balance shaft chain tensioner arm (B).
5. | Remove the balance shaft chain guide (C).
6. | Remove the oil pump & balance shaft module (A) and balance shaft chain (B).
Do not disassemble the oil pump & balance shaft module.
[2.0L Engine only]
1. | Remove the timing chain. (Refer to timing system in this group)
2. | Remove the oil pump chain mechanical tensioner (B).
3. | Remove the oil pump chain guide (D).
4. | Remove the oil pump (A) and oil pump chain.
Installation
[2.4L Engine only]
1. | The key of crankshaft should be aligned with the mating face of main bearing cap. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.
2. | Confirm the balance shaft module timing mark. Timing marks to be visually aligned with centers of adjacent cast timing notches.
3. | Install balance shaft module that the timing mark of balance shaft module sprocket should be matched with the timing mark (color link) of balance shaft chain.
Tightening torque : 22.5~26.5N.m (2.3~2.7kgf.m, 16.1~19.5lb-ft) + (103~107°)
Bolting order
A. | Assemble the bolts in order number as shown with seating torque 25.5 N.m (2.6kgf.m, 18.8 lb-ft)
B. | Unfasten the bolts as reverse bolting order. (4-3-2-1)
C. | Assemble the bolts as specified bolting order in same increments as follows.
4. | Remove the balance shaft chain guide (C).
Tightening torque : 9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
5. | Install the balance shaft chain tensioner arm (B).
Tightening torque : 9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
6. | Install the balance shaft chain hydraulic tensioner (A) then remove the stopper pin.
Tightening torque : 9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
7. | Confirm the timing marks.
8. | Install the timing chain. (Refer to Timing system in this group)
[2.0L Engine only]
1. | The key of crankshaft should be aligned with the mating face of main bearing cap. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.
2. | Assemble the crankshaft sprocket on the crankshaft as the front mark on the crankshaft sprocket to be outward.
3. | Tighten the oil pump tensioner bolt(A) after placing the tensioner spring on the dowel pin located in ladder frame, and then insert stopper pin to fix the tensioner(B).
Tightening torque : 9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb.ft)
4. | Assemble the oil pump chain on the crankshaft sprocket.
5. | Assemble the oil pump assembly (C) on the ladder frame as placing oil pump sprocket in to oil pump.
Tightening torque : 7.8~11.8N.m (0.8~1.2kgf.m, 5.8~8.7lb.ft) + 17.7~21.6N.m (1.8~2.2kgf.m, 13.0~15.9lb.ft) + 27.5~31.4N.m (2.8~3.2kgf.m, 20.3~23.1lb.ft)
Bolting order
