Mazda 3 Camshaft
The Mazda 3 Camshaft times the breathing of the engine so that the engine can breathe at the highly opportune times, providing it with smooth power and efficiency. The lobes are made of cast iron or hardened steel, and they ride on journals and force the valves open while the springs make them close, and the shaft turns at half crankshaft speed via a timing belt or chain that ensures that the movement of the pistons and the valves are perfectly synchronized. The first and second generations of the Mazda mini engine applied a block-mounted design, which was shared with overhead valve engines, with the lifters, pushrods, and rocker arms transmitting the motion upwards. Subsequent Mazda powerplants switched to single overhead cam design with a single shaft running above the head, and the present 3 uses double overhead cam design, which separates the intake and exhaust functions into two shafts with faster high-rpm reaction. The primary distinction between these styles is the number of components and the direction the lobe lift follows to the valves, which ranges from long pushrods in OHV engines to direct bucket followers in DOHC engines. Newer engine models have variable valve timing that can change the Camshaft timing to either advance or retard, providing a wider range of torque without additional fuel consumption. In spite of material strength, lack of oil may cause lobes to be wiped and misuse of valves to misfire; therefore Mazda suggests that timely lubrication be applied to ensure that the Camshaft spins freely and the four-stroke cycle hums.

Mazda 3 Camshaft Parts and Q&A
- Q: How should camshafts and valve lifters be removed and reinstalled during a procedure on Mazda 3?A:At any time that the cams are to be pulled to perform a procedure, it is recommended to verify the valve clearance prior to breaking them down so that any new lifters necessary are available to be ordered out of a dealership. Start by taking out the Timing Chain, marking the location of the no.1 cylinder cam lobes and locations of the slots in the ends of the camshafts to line up with the slot during reassembly. Then, taken-out the camshaft sprockets and label the camshaft phaser/sprocket on the intake camshaft to be installed in the correct position. The Variable Valve Timing models have various camshaft sprocket bolts that are required to be aware of, with appropriate washers being used as necessary. The camshaft carrying caps are numbered and should be returned to their original place, the side with the number face upwards. Relax the camshaft bearing cap bolts gradually, then pull the caps off taking note of their markings, and take out the camshafts. Store lifters in small containers and do not mix them. Look at the camshafts and lifters, and then feel their wear and roundness, and take the outside diameter of all lifters and see whether they have any appreciable differences. Inspect the camshaft lobes visually and inspect the bearing journals visually. Measure the diameter of each journal and measure the degree of running clearance of the bearing journal with Plastigage. In case one of the bearings becomes worn out of service, it may be required to replace a camshaft. In order to measure camshaft endplay, check with a dial indicator with the bearing surfaces cleaned. To install, make sure that the crankshaft is at TDC, lubricate the lifter bores and camshaft bearing surfaces, and then place the lifters and camshafts in place using care to ensure that they fit in their original position. Clean all mating surfaces and oil the camshaft journals and lobes and then put the bearing caps into their normal positions. Install the sprockers to the camshafts, in sequence to the required setting of camshaft bearing cap bolts, and when installing the camshaft bearing cap bolts, it is important to install the various washers as necessary. Install the Valve Cover after finishing the reassembly process which consists of replacing the timing chain and adjusting the valve timing, and the valve clearance.
