How to align the timing chain on a Kia Forte?

[Gwen]

Forte timing chain alignment procedure is as follows: 1. Align the timing mark of the crankshaft sprocket with the upper surface of the cylinder head, then install the chain tensioner arm. 2. Rotate the crankshaft to align the vehicle transmission and flywheel. 3. Rotate the camshaft. Align the timing gear mark on the camshaft with the base of the valve chamber. 4. Align the rectangular projection on the drive end of the engine oil pump shaft with the crankshaft direction. 5. Insert the distributor assembly into the mounting hole and align the distributor rotor with the mark on the housing. 6. Install the distributor cover, then connect the spark plug wires and various internal components. 7. Install the timing belt and start the engine for testing. More about the Forte: The Forte is a compact car produced by Dongfeng Yueda Kia. In terms of power, the Forte is equipped with a 1.6-liter naturally aspirated engine with a maximum horsepower of 123. In terms of transmission, the Forte offers a 6-speed manual or a 6-speed automatic transmission. For suspension, the front suspension is a MacPherson independent suspension, and the rear suspension is a torsion beam non-independent suspension.

Removing the timing chain indeed requires meticulous operation. Having done it several times, I'll share the steps. First, remove the valve cover and timing chain cover, locate the crankshaft pulley, and use a wrench to rotate it to the top dead center position of cylinder one. The groove mark on the crankshaft gear must align with the protrusion on the oil pump housing. For the camshafts, the dot mark on the intake camshaft gear should face upward, while the oval mark on the exhaust camshaft gear should face downward, and both marks must be horizontally aligned. There are three yellow links on the chain, corresponding to the triangular mark on the crankshaft gear and the notch marks on the two camshaft gears. After alignment, install the chain guide and tensioner, manually rotate the crankshaft two turns to recheck the alignment. Throughout the process, ensure the camshafts do not rotate on their own—it's advisable to use special tools to secure them. Finally, remember to replace the sealing gasket with a new one.

The most dreaded scenario during calibration is mistiming the camshaft, a mistake I've personally experienced. First, ensure the engine is cold. When removing the outer cover, mark the positions of all screws. Crankshaft positioning is critical: use a 19mm socket to turn the crankshaft pulley bolt, observe through the oil dipstick hole, and stop when the first cylinder's piston reaches its highest point. At this moment, check the crankshaft gear—the inner triangular mark should align with the ridge of the oil pan joint surface. Adjust the camshaft using an adjustable wrench on its hex section; the notches at the rear ends of the intake and exhaust camshafts should form a horizontal line. The colored links of the new chain should fit into the crankshaft's triangular groove and the camshaft's positioning groove. After installing the hydraulic tensioner, make sure to remove the limit pin. It's best to have two people cooperate during the entire process. Finally, apply a circle of sealant before reinstalling the front cover.

My understanding of the timing principle is: to precisely transmit the crankshaft position to the camshaft via the chain. There are five key operational points: rotate the crankshaft to the top dead center of the first cylinder, align the golden mark on the chain with the crankshaft keyway; ensure the dotted marks on the two camshaft gears form a horizontal line; pre-compress the hydraulic tensioner with a zip tie before installation; replace the chain together with the guide rail; finally, manually rotate the crankshaft two turns to check if the marks reset correctly. The most error-prone step is fixing the camshaft, which can be secured by using two 24mm wrenches to clamp the journal to prevent rotation. It is recommended to purchase a timing repair kit, which includes gaskets and locating pins.
