Timing Chain Replacement. Do you have a worn-out timing chain and you feel it has a need for replacement but you don’t know how to go about the replacement process? You don’t need to worry about anything concerning timing chain replacement because in the article we will be giving you the basic required information you need.
Except there is a specific fault, the timing chain is replaced between 80,000 and 120,000 miles. Chain problems are frequent in automobiles with increasing mileage. If you’re driving an older car or one with a lot of miles on it, Keep an eye out for signs that the timing chain is failing.
Timing Chain Replacement – Timing Chain
As is often the case with other high-performance vehicles, some parts of these vehicles are also prone to wear and tear. Such part is the timing chain tensioner. A timing chain is a metal chain that runs within the engine and is lubricated by the engine oil. This chain is kept under the right tension by a timing chain tensioner that is operated by oil or hydraulic pressure of a spring-loaded mechanism.
Now, what is the work of a timing chain? A timing chain brings the connection between the camshaft and the crankshaft and coordinates the rotating motion of these two parts. The timing chain tensioner ensures that the timing chain is on the right tension to enable the top and bottom parts of the engine to rotate in sync.
Signal of a Failing Timing Chain
If the timing chain fails, the engine will stall immediately. This is because the engine can no longer turn synchronously. It may lead to internal engine damage if the engine does not have valve reliefs built into the engine’s pistons.
The check engine light will illuminate on the dashboard in the event of total failure, and OBD trouble codes for misfires, crankshaft position, and camshaft position will be stored. In addition, when attempting to start the engine, it may have a different sound as usual.
How Often Should One Replace Their Timing Chains and Gearsets?
Timing chains and timing gears are meant to last the life of the vehicle, and typically never need a replacement for maintenance purposes. Chain failures tend to include the timing chain tensioner but the timing chain requires replacement only when broken or stretch too far to maintain proper camshaft timing. Timing chain gear sets require replacement in many cases when the timing chain is replaced, especially in the event of failure.
How to Replace Timing Chain and Gearsets
Replacement involves removal of the timing cover, timing chain tensioner, timing chain, timing gears, and timing chain guide rails. These are all replaced during a timing chain service. Chain guides are typically held in place by pins or fasteners, and one end will typically be left to pivot freely with the timing chain.
Timing gears may be unbolted and removed, but some require a gear puller to remove them from their driven components. Now if all the components are removed, the timing components can be installed onto the engine, and the engine will be tested for proper operation and timing before additional components are replaced.
Is it Good to Drive With a Bad Timing chain?
It is not recommended to drive a vehicle suspected of timing component damage. This can quickly result in complete engine failure as described above. If the timing chain has already broken, the engine will not start until the timing chain and gear have been replaced. A rating or slapping noise from the timing chain that does not stop within seconds of starting the engine requires immediate diagnosis as well.
What to look out for when dealing with Timing Chain Issues
It is necessary for the motor mounts to be removed from the vehicle, as well as an engine cooling fans, the radiator, and all engine accessories. This may include components like the alternator, A/C compressor, mounting brackets, the coolant of fuel lines, and any other component that interfaces with access to the timing chain cover.
Should I Replace the Accessory Drive Belt When Replacing a Timing Chain?
The timing chain is located inside the engine which needs several steps to get to the timing drive, making timing chain and timing drive component inspection and replacement difficult. When replacing the timing chain, it’s important that the accessory belt, tensioner, idler pulleys, and water pump are inspected as these components wear at a similar rate.
Timing Chain Replacement Cost
Timing Chain Replacement Cost is high but it can be afforded. The cost or range does not include taxes and fees and does not factor in your specific model year or unique location. The range is also based on the number and age of your vehicle.
