The part Gear transfers rotational force from the crankshaft to The part, ensuring precise valve timing. Made from hardened steel with precision-cut teeth, it meshes with the idler gears to maintain synchronization. The gear features a keyway for positive alignment and is designed to withstand the high torque of engine operation.
The part Pulse Disc provides position feedback to the engine control unit, enabling precise fuel injection and ignition timing. It features a series of machined teeth and windows that are read by The part position sensor. This Camshaft component is critical for proper engine management and emission control.
These M8 flange bolts secure the pulse disc and other components to The part. Grade 10.9 with a zinc-nickel coating, they provide reliable clamping force and corrosion resistance, ensuring secure attachment in The part assembly.
This idler gear assembly transfers drive from the crankshaft gear to The part gear. Mounted in the cylinder head, it includes a precision-ground gear and a needle bearing for smooth, quiet operation. In The part system, it ensures accurate timing between the crankshaft and camshaft.
This hardened steel shaft supports the small idler gear. It is precisely ground to ensure accurate gear alignment and minimal wear. In The part assembly, it provides a durable pivot point for the idler gear, maintaining correct tooth engagement.
These socket head cap screws secure the idler gear assemblies to the engine block. Grade 10.9 with a zinc-nickel coating, they provide high clamping force and are resistant to loosening in The part system.
This idler gear assembly is mounted in the crankcase and transfers power from the crankshaft to the cylinder head idler gears. In The part system, it is a critical link in the timing chain, ensuring accurate synchronization across the entire valve train.
This additional idler gear assembly provides an intermediate drive between the crankcase idler and The part gear. It is identical in construction to the other idler gears, ensuring consistent timing and load distribution throughout The part drive system.
The Large Idler Shaft supports the larger idler gear in the timing train. Made from case-hardened steel with a ground bearing surface, it provides a robust pivot for the high-torque idler gear in The part assembly.
These heavy-duty M14 flange bolts secure the main idler gear assemblies to the engine block. Grade 10.9 with a zinc-nickel coating, they provide exceptional clamping force and vibration resistance in The part system.
The part is engineered with precision-ground lobes and accurate timing marks, ensuring that the intake and exhaust valves open and close at the exact moment for maximum engine efficiency. This results in improved power output, better fuel economy, and reduced emissions.
