No.
Both, cranshaft to camshaft sprocket, belt, camshaft sprocket to cams, chain.
Camshaft Sensor is used to adjust the timing to to belt stretch
The camshaft is turned by the timing chain or belt.
if you mean locking,as in the fitting of timing belt,it is a round hole,inside elongated hole,nearest the bulkhead
No the timing belt drives the camshaft. A serpentine belt drives accessories such as alternator, power steering and ac.
Its has a timing belt (2.0l 16 valve dual cam ) and a timing chain in rear of camshaft.
The valve timing on a 156 is set by finding TDC on #1 cylinder with a dial gauge and then locking the cams with the camshaft locking blocks (on #2 inlet and #3 exhaust). Loosen the 4 screws on the inlet cam sprocket and fit the timing belt. Adjust the timing belt tensioner so the pointer points to the hole and then re-tighten the inlet cam sprocket screws. You have done the valve timing.
To replace the camshaft seals on a 2004 Volvo XC70, first ensure the engine is cool and disconnect the battery. Remove the timing belt cover and loosen the timing belt to access the camshaft gears. Carefully remove the old seals using a seal puller or a flat tool, then install the new seals, ensuring they sit flush. Reassemble the timing belt and cover, and reconnect the battery before starting the engine to check for leaks.
The timing belt of a vehicle is responsible for linking the activities of the crankshaft and camshaft. A damaged timing belt could be responsible for a faulty engine.
The timing belt effects your camshaft timing, and in some engines your ignition timing (if the distributor or crank trigger runs off a pulley driven by your timing belt). Directly, your timing belt has no effect on your shifting. However, variances in camshaft timing will make your engine run differently and that MAY effect at what point the transmission shifts.
To change the timing belt on a 1995 Buick Riviera, first disconnect the battery and remove any components obstructing access to the timing belt cover. Then, remove the timing belt cover, ensuring you align the timing marks on the crankshaft and camshaft to maintain proper timing. Next, loosen the tensioner and remove the old timing belt, replacing it with a new one while ensuring proper tension. Finally, reassemble the components, recheck the timing, and reconnect the battery.
disconnect negative battery cable rotate the engine in the normal direction of rotation(clockwise)until the no.1 is TDC remove the accessory drivebelt loosen the water pump pulley bolts and then remove the water pump pulley using a chain wrench or a strap wrench to hold the crankshaft pulley,loosen the crank pulley bolt and then remove the pulley bolt and the crank pulley.Make sure that you dont move the No.1 cylinder from TDC while loosening the crank pulley bolt.After removing the crankshaft pulley remove the timing belt retainer/guide flange remove the 4 upper timing belt cover bolts and then remove the upper timing belt cover.Remove the lower timing belt cover bolts make sure that the timing belt camshaft sprocket timing marks are aligned with the top of the cylinder head if your planning to re-use the timing belt put a directional arrow indicating the normal clockwise direction of rotation on the belt remove the timing belt tensioner pulley bolt and then remove the tensioner pulley remove the timing belt remove the timing belt idler pulley bolt and then remove the idler pulley if the camshaft sprocket is damaged or must be removed to replace the camshaft seal or to strip the cylinder head for overhaul use a wrench to hold the cramshaft in place and then remove the sprocket retaining bolt.Then remove the camshaft sprocket from the end of the camshaft remove the crankshaft tioming belt sprocket
