TIMING BELT & CHAIN REPLACEMENT PROCEDURE FOR ACCENT ALPHA DOHC ENGINE
This TSB supersedes TSB # 97-20-010
DESCRIPTION:
This bulletin describes the valve timing procedures necessary when installing a timing belt or transfer drive chain on 1995-1997 Accent models. Improper valve timing may result in driveability conditions such as loss of power, poor idle quality, and, in severe cases, stalling and cylinder head damage.
SERVICE PROCEDURE:
Overview of the Alpha DOHC engine valve timing system:
Timing Belt and Drive Chain Installation:
CAUTION:
If the cylinder head was removed, the camshafts must be set to TDC BEFORE installing the head.
If the removal of camshaft(s) was necessary, follow steps 1-5. If camshafts were not removed, proceed to step 6.
1. Install transfer drive chain onto transfer gears.
Note:
Align timing marks to the bronze colored or punch-marked links on the chain.
2. Apply lubrication to assembly and install camshafts.
3. Install bearing caps, checking the marks on bearing caps for proper location.
4. Using Special Service Tool, P/N 09221-21000, install the camshaft oil seal.
Note:
Prior to installation, apply a light coat of motor oil to internal and external surface of the seal.
5. Install the camshaft sprocket.
Tightening torque: 59-74 lb.ft. (80-100 Nm.)
6. Align mark on the crankshaft sprocket to protrusion on front case.
7. Align the camshaft sprocket so that the hole in the sprocket web is on the top.
Note:
Mark on bearing cap must be visible through hole in sprocket.
8. Install the timing belt. Tension the belt so that it deflects 4-6 mm (.16-24 in.) under a force of 2 kg (4.4 lbs.).
9. Using a suitable wrench, rotate the engine several complete revolutions, then recheck the timing marks and the belt tension.
