Hyundai Genesis: Timing System / Timing Chain Repair procedures

Removal

1.

Set No.1 cylinder to top dead center (TDC)/compression. (1) Turn the crankshaft pulley clockwise and align its groove with the timing mark "T" of the lower timing chain cover. (2) Check that the mark (A) of the camshaft timing sprockets is in the straight line on the cylinder head surface as shown in the illustration. If not, turn the crankshaft clockwise, making one revolution (360°). Do not rotate engine counterclockwise.

2.	Remove the timing chain cover. (Refer to Timing System - "Timing Chain Cover") Before removing the timing chain, mark the RH/LH timing chain with an identification based on the location of the sprocket because the identification mark on the chain for TDC can be erased.

3.	Lower the tensioner link (A), compress the piston of the RH timing chain tensioner, and fix the tensioner with a fixing pin.

4.	Remove the RH timing chain cam to cam guide (A).

5.	Remove the RH timing chain auto tensioner (A) and the RH timing chain tensioner arm (B).

6.	Remove the RH timing chain guide (A).

7.	Remove the RH timing chain (A).

8.	Remove the oil pump chain tensioner assembly (A).

9.	Remove the RH crankshaft chain sprocket (A).

10.	Remove the oil pump chain sprocket (A) and oil pump chain (B).

11.	Remove the crankshaft sprocket (A). (O/P & RH camshaft drive)

12.	Install a set pin after compressing the LH timing chain tensioner.

13.	Remove the LH timing chain cam to cam guide (A).

14.	Remove the LH timing chain auto tensioner (A) and LH timing chain tensioner arm (B).

15.	Remove the LH timing chain guide (A).

16.	Remove the LH timing chain (A).

17.	Remove the crankshaft sprocket (A). (LH camshaft drive)

18.	Remove the timing chain auto tensioner assembly adapter (A).

Inspection

1.	Check the camshaft sprocket and crankshaft sprocket for abnormal wear, cracks, or damage. Replace as necessary

2.	Inspect the tensioner arm and chain guide for abnormal wear, cracks, or damage. Replace as necessary.

3.	Check that the chain tensioner piston moves smoothly and that the ratchet operates normally. Replace as necessary.

Installation

1.	The key (A) of crankshaft should be aligned with the timing mark (B) of timing chain cover. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.

2.	Install the timing chain auto tensioner assembly adapter (A).

3.	Install the crankshaft sprocket (A). (LH camshaft drive).

4.

Install the LH timing chain (A). To install the timing chain with no slack between each shaft (cam, crank), follow the procedure below. Crankshaft sprocket >Exhaust camshaft sprocket > Intake camshaft sprocket. The timing mark of each sprocket should be matched with timing mark (color link) of timing chain when installing timing chain.

5.	Install the LH timing chain guide (A). Tightening torque : 19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~ 18.1 lb-ft)

6.	Install the LH timing chain tensioner arm (B) and LH timing chain auto tensioner (A). Tightening torque : A : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft) B : 18.6 ~ 21.6 N.m (1.9 ~ 2.2 kgf.m, 13.7 ~ 15.9 lb-ft)

7.	Install the timing chain cam to cam guide (A). Tightening torque : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

8.	Remove the LH timing chain auto tensioner stopper pin (A).

9.	Install the crankshaft sprocket (A).

10.	Install the oil pump chain sprocket (A) and oil pump chain (B). Tightening torque : 19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~ 18.1 lb-ft)

11.	Install the oil pump chain tensioner assembly (A). Tightening torque : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

12.

Install the RH timing chain (A). To install the timing chain with no slack between each shaft (cam, crank), follow the procedure below. Crankshaft sprocket >Intake camshaft sprocket > Exhaust camshaft sprocket. The timing mark of each sprocket should be matched with timing mark (color link) of timing chain when installing timing chain.

13.	Install the RH timing chain guide (A). Tightening torque : 19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~ 18.1 lb-ft)

14.	Install the RH timing chain auto tensioner (A) and the RH timing chain tensioner arm (B). Tightening torque A : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft) B : 18.6 ~ 21.6 N.m (1.9 ~ 2.2 kgf.m, 13.7 ~ 15.9 lb-ft)

15.	Install the RH timing chain cam to cam guide (A). Tightening torque : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

16.	Remove the RH timing chain auto tensioner stopper pin (A).

17.

After rotating the crankshaft two times in regular direction (clockwise viewed from front), confirm the timing mark. Always turn the crankshaft clockwise. Turning the crankshaft counter clockwise before building up oil pressure in the hydraulic timing chain tensioner may result in the chain disengaging from the sprocket teeth.

18.	Install the timing chain cover. (Refer to Timing System - "Timing Chain Cover")

• Refill engine oil. • Clean the battery posts and cable terminals with sandpaper. Assemble and then apply grease to prevent corrosion. • Inspect for fuel leakage. - After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and that the fuel line is pressurized. - Repeat this operation two or three times, then check for fuel leakage at any point in the fuel lines. • Refill radiator and reservoir tank with engine coolant. • Bleed air from the cooling system. - Start engine and let it run until it warms up. (Until the radiator fan operates 3 or 4 times.) - Turn Off the engine. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system. - Put radiator cap on tightly, then run the engine again and check for leaks.
