Unfortunately, it is becoming increasingly common to find worn threads, damaged mounting faces and poor previous repairs on older engine cases.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eDuring engine disassembly, the idler posts are often subjected to impact or leverage which can bruise or distort the aluminium mounting face. Even a small amount of damage can prevent the idler from seating perfectly flat, causing it to run out of alignment. The result is incorrect timing belt tracking, premature belt wear and, in the worst cases, complete timing belt derailment leading to catastrophic engine failure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eRather than simply repairing the damaged thread, RCM restores the entire mounting point using precision machining techniques.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eEach engine case is securely mounted on our precision milling machine where the idler post is carefully indicated to ensure absolute accuracy. The mounting face is then lightly machined to restore a perfectly flat seating surface before the original thread is removed and replaced with a motorsport-grade Time-Sert® solid steel thread insert.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eBecause the machining is carried out on the milling machine—not by hand—the new thread is installed perfectly perpendicular to the mounting face. This guarantees the idler pulley sits perfectly square against the engine case, allowing the timing belt to track exactly as Subaru intended.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe finished result is stronger than the original aluminium thread, providing a permanent engineering solution that is ideally suited to standard road cars, fast road builds and high-performance motorsport engines alike.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eFeatures \u0026amp; Benefits\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003ePrecision restoration of damaged timing belt idler mounting posts.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCorrects bruised, distorted or uneven idler mounting faces.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePrecision machined on a milling machine for absolute accuracy.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMotorsport-grade Time-Sert® solid steel thread insert.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSteel thread provides significantly greater durability than the original aluminium thread.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEnsures the idler pulley sits perfectly square to the engine case.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMaintains correct timing belt tracking.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReduces the risk of premature belt wear and catastrophic timing belt failure.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eA permanent, professional engineering solution.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRecommended during every quality EJ engine rebuild where damage or wear is present.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eAt Roger Clark Motorsport, we don't believe in temporary repairs.
