Why is the timing chain important to an engine?
The timing chain is a crucial piece of equipment that, when working properly, causes the valves to open and close at very specific intervals in relation to the position of your pistons for optimum operation of your engine.
Do you need an owner’s manual to change a timing chain?
Locate your owner’s manual. You will most likely need it to disassemble and reassemble various parts. Also verify that your model is equipped with a timing chain and not a timing belt. These two parts perform the same task, but replacing them can be quite different. This procedure is only for replacing a timing chain.
What are the bright links on a timing chain?
Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
What should I do to tighten my timing chain?
Tighten the chain according to your car manual’s specifications. Some chains are tensioned by adjusting either the crankshaft gear or the camshaft gear, while others have an automatic tensioner. This will vary by make and model of your car. The important thing is to make sure that your timing belt is as tight as it should be.
How are gears connected to the timing chain?
Locate marks on your crankshaft and camshaft gears. These gears are connected by the timing chain so that the position of the piston (connected to the crankshaft) correlates directly to the opening of the fuel and exhaust valves (operated by the camshaft) to keep your engine running smoothly.

How do you change the timing chain on a water pump?
Remove the belt. Once tension is released, the belt should slide off of the other pulleys easily. Remove the heater hoses from the water pump. If your model has heater hoses attached to the water pump, loosen the hose clamps with a screwdriver and slide them back onto the hose. Wiggle the hose and pull it off of the water pump.
Why does a timing chain have a tensioner?
It ensures that the piston is close to or at top dead center at the moment of combustion. If a valve is open or the plugs don’t fire at the right time the air and fuel that have entered the combustion chamber are not going to ignite. Most timing chains use a tensioner to keep them tight and to keep them from jumping.
What happens to the timing of the piston and valve?
The precise timing of the piston and valves continues similarly through all four cycles. And this timing is closely calculated to provide efficient engine operation. If the cam loses valve timing just a few degrees, however, your customer will notice a severe power loss or a no-start condition. Engine damage may occur, as well.
Can a bad timing chain cause an engine to misfire?
Engine misfires. The timing chain method is more common with consumer vehicles and high performance engines. Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crank shaft. This results in the engine’s timing to fall out of calibration and often results in a misfire.
How are pistons installed in a clockwise rotation engine?
viewed from the front of the engine), rods are installed similar to a clockwise rotation engine, where the larger chamfer side of the big end faces the fillet. However, if the pistons feature an offset pin, the piston must be installed “backwards” relative to installation in a clockwise engine.
What kind of compression ratio does a Nissan KA24E have?
The compression ratio is 8.6:1 or 9.1:1 for early 1989 Nissan 240SX. The Nissan KA24E engine produced 143 PS (105 kW; 140 HP) at 5,600 rpm of horsepower and 206 Nm (21.0 kg·m; 152.0 ft·lb) at 4,400 rpm of torque. The Nissan KA24E motor has a cast-iron cylinder block, cast steel connecting rods, a half-counterweighted forged steel crankshaft.
How do you change the timing chain on a radiator?
Trace the radiator hoses from the radiator back to the engine. Squeeze the hose clamps with pliers and slide them back onto the hose. Wiggle the hose to break it free and move it out of the way. There is no need to remove the radiator.
What happens when the timing chain loosens on a Nissan?
When timing chains loosen it leads to engine rattles, issues with misfiring, problems accelerating and – eventually – bent valves or rods and catastrophic engine failure.
Where is the timing chain in an engine?
Every internal combustion engine has a timing chain or belt. It’s in the front of the engine attached to a set of gears and pulleys that power components like the crankshaft and camshaft. A properly tensioned chain is critical to maintaining the timing between the pistons and the valves.
Why do I need a tensioned timing chain?
A properly tensioned chain is critical to maintaining the timing between the pistons and the valves. When timing chains loosen it leads to engine rattles, issues with misfiring, problems accelerating and – eventually – bent valves or rods and catastrophic engine failure.
Why does my engine have low compression after a timing belt replacement?
If you know that you got low compression after a timing belt replacement, check the timing. Anyways, if you experience low compression on all cylinders, check the timing. These are found between the crankshaft and camshaft. Valves control the outflow of exhaust gases from the combustion chambers.
