TIMING CHAIN SOLUTIONS
As engine woes with the BMW 1, 3 and 5 Series continue, BGA says its solution is the best option
In some cases, it is thought that the timing chain lasts the life of the engine, such as that in the BMW N47 Engine.
In this case, BMW’s engineers designed the engine so that the timing chain is located at the back, away from an easy service area, as it was expected to not need maintenance. BGA says though that also in this case, due to wear, the timing chain often begins to rattle between 40k-70k miles which indicates imminent failure.
When the timing chain does snap, as in most cases, this will cause catastrophic damage where the pistons hit the valves, causing them to bend as they collide with the rocker arms.
When this happens, the engine must be removed from the vehicle for repair and should this be the case, BGA says you need the BGA TC0900FK Timing Chain Kit, and you might need the valves and rocker arms too (BGA Part numbers: Inlet Valves V166200, Exhaust Valves V166211, Rocker Arms RA0615).
BGA explains that its TC0900FK kit for the BMW N47 includes uprated specification upper and lower Timing Chains, Oil pump chain, Tensioners, Guide Arms and Sprockets. BGA also includes the crankshaft oil seal and a new oil feed pipe too, which is something BGA says it does to ensure a completely comprehensive kit is supplied.
As with all of BGA’s Timing Chain Kits, they have been designed by BGA’s experienced Technical Engineering Team at their HQ in the heart of Wiltshire; and the company says this kit provides superior quality and installer peace of mind.
When you open the box, you will find specific kit instructions and also a reminder that the upgraded 94mm tensioner is included due to BMW’s design succession. BGA explains that it introduced kits to give the installer everything they need to complete the job including Gaskets, Seals and Feed Pipes where appropriate, allowing the installer to save time and money.
Its range covers more than 350 references for 7000+ relevant applications, which it says makes it one of the largest suppliers of Timing Chain Kits in Europe. All of BGA’s kits are engineered and Q.C Tested in house by its own automotive engineers and where possible, improve on the original, says BGA.
BGA states that when replacing components, it is best practice to replace all of the associated parts. By doing so, the condition of the timing components, which are so critical to the operation of the engine, will now be all uniform and wear together again, preventing premature wear and failure.
