Looking at the importance of making sure any system that includes a belt-in-oil (BIO) timing belt is serviced according to the manufacturer’s schedule, using the Ford 1.0-litre EcoBoost Fox engine as an example, Dayco’s National Sales Manager Steve Carolan said: “The timing belt must be replaced at 150,000 miles or every 10 years, whichever comes soonest. He continued: “When it comes to the Tourneo Connect and Courier however, the replacement mileage is slightly lower, at 140,000 miles.” The first thing technicians should do is to assess the condition of the oil: “Although the BIO innovation is a fantastic solution, the engine can be prone to oil contamination. Whenever carrying out a scheduled oil and filter change technicians should check for the smell of petrol fumes. If this is detected, further investigation must be made as the failure of the belt will have catastrophic consequences. A sensible starting point is to check the strainer the oil will have passed through when draining from the sump. It’s 44 AFTERMARKET JUNE 2023 CLUTCH AND TRANSMISSION www.aftermarketonline.net possible that fragments of the belt will be left behind. “If any evidence of debris is found, the next step is to remove the camshaft cover to examine the back, which will reveal whether the contaminated oil has begun to degrade the surface of the belt. Moderate increase in the width of the belt, commonly referred to as belt swell, is not an issue, unless of course it’s so excessive as to cause the belt to foul, but this will be evident if there is damage to its edges.” Steve added: “Should the belt need to be replaced, as the original equipment supplier for both the timing and oil pump drive systems for these engines, Dayco has replacement in its aftermarket range.” Dayco has produced an installation video, which is available via YouTube: https://youtu.be/fDkoaPwbfpg Best practice First Line, via its Borg and Beck brand, has launched a technical poster covering top tips for clutch fitment.
