Kia Sorento (XM, 2011-2015) Service Manual / Engine Mechanical System / Lubrication System / Balance Shaft & Oil Pump Installation

BSM(Balance Shaft Module) Chain System

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.
Insert a stopper pin (A) on the BSM to hold the sprocket at the reference position with the timing mark (B) aligned with the timing notch (C).

  
New BSM has already been installed with a stopper pin at the reference position.
3.
Install the BSM (Balance Shaft Module).
(1)
Tighten the bolts with seating torque 29.4 N.m (3.0kgf.m, 21.7 lb-ft) and then loosen the bolts.
(2)
Using the SST (Torque Angle Adapter, 09221-4A000), tighten the bolts with specified tightening torgue and angle.
Tightening torque
Bolts (A) (M9x181.5) : 22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 88° ~ 92°
Bolts (B) (M9x100) : 22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 43° ~ 47°
  
Do not reuse the BSM bolts.

 

 
4.
Install the balance shaft chain (E).
  
The timing marks of BSM sprocket and crankshaft sprocket should be matched with the timing marks (color link) of balance shaft chain.
5.
Install the balance shaft chain guide (D).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
6.
Install the balance shaft chain tensioner arm (C).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
7.
Install the balance shaft chain tensioner (B) then remove the stopper pin (A).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

8.
Remove the stopper pin (A) of balance shaft module.
9.
After rotating crankshaft 2 revolutions in regular direction (clockwise viewed from front), confirm that the timing mark and notch are aligned at the reference position.
10.
Install the other parts in the reverse order of removal.

BSM (Balance Shaft Module)

1.
Insert a stopper pin (A) on the BSM to hold the sprocket at the reference position with the timing mark (B) aligned with the timing notch (C).

  
New BSM has already been installed with a stopper pin at the reference position.
2.
Install the BSM (Balance Shaft Module) (A).

  
The timing mark of BSM sprocket should be matched with the paint-marked link of the timing chain.

3.
Install the BSM mounting bolts.
(1)
Tighten the bolts with seating torque 29.4 N.m (3.0kgf.m, 21.7 lb-ft) and then loosen the bolts.
(2)
Using the SST (Torque Angle Adapter, 09221-4A000), tighten the bolts with specified tightening torgue and angle.
Tightening torque
Bolts (A) (M9x181.5) : 22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 88° ~ 92°
Bolts (B) (M9x100) : 22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 43° ~ 47°
  
Do not reuse the BSM bolts.

4.
Remove the stopper pin (A) from the BSM.
5.
Remove the stopper pin (A) from the tensioner.
6.
Confirm the BSM timing mark.
(1)
Turn the crankshaft pulley and align its groove with the timing mark "T" of the timing chain cover.
(2)
Confirm that the sprocket timing mark (A) is visually aligned with center of adjacent cast timing notch (B).
7.
Install the oil pan.
(1)
Using a gasket scraper, remove all the old sealant material from the gasket surfaces.
(2)
Before assembling the oil pan, liquid sealant Loctite 5900H, Threebond 1217H or equivalent should be applied on oil pan.
The part must be assembled within 5 minutes after sealant was applied.
Bead width : 2.5 mm (0.10 in.)

 

  
•
When applying sealant gasket, sealant must not be protruded into the inside of oil pan.
•
To prevent leakage of oil, apply sealant gasket on the inner threads of the bolt holes.
(3)
Install the oil pan (A). Uniformly tighten the bolts in several passes.
Tightening torque
Bolts B (M9) : 26.5 ~ 30.4 N.m (2.7 ~ 3.1 kgf.m, 19.5 ~ 22.4 lb-ft)
Bolts C (M6) : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

  
•
After assembly, wait at least 30 minutes before filling the engine with oil.
•
Always use a new drain plug gasket.
8.
Install the A/C compressor bracket (A).
Tightening torque :
19.6 ~ 23.5 N.m (2.0 ~ 2.4 kgf.m, 14.5 ~ 17.4 lb-ft)

9.
Remove the A/C compressor lower mounting bolts (A).
Tightening torque :
19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m , 14.5 ~ 18.1 Ib-ft)

10.
Refill with engine oil.
11.
Install the RH front wheel.
12.
Install the under cover.
