Timing Chain Replacement near Lilburn, Georgia

A vehicle with the above symptoms would be suspected of timing chain failure immediately, and a quick inspection can verify the diagnosis right away. This would involve removal of the timing chain inspection cover, and noting the observed condition of the timing chain. If the timing chain is found to be broken, or the camshaft position is too far out of specification, the timing chain will require replacement to restore the vehicle to operating condition.

Replacement involves removal of the timing cover, timing chain tensioner, timing chain, and timing chain guide rails. These are all replaced during a timing chain service. Timing 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. Once all 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.

Since this service requires removal of the timing cover, it is recommended to replace all timing components, water pump, and front seals at the same time, unless they have been recently serviced. This is much more cost effective than returning for the same service after a partial service interval has elapsed.

It may be necessary for the motor mounts to be removed from the vehicle, as well as engine cooling fans, the radiator, and all engine accessories. This may include components like the alternator, A/C compressor, mounting brackets, coolant or fuel lines, and any other component that interferes with access to the timing chain cover.

Since timing chain replacement necessitates much deconstruction and the removal of timing components, it is not recommended for the DIYer to attempt this task. A thorough knowledge of internal engine components, engine timing, additional systems, and several specialty tools are required to properly perform this repair. If there is any doubt surrounding accomplishing this task correctly, even the seasoned DIYer should leave this job to a professional.
