Because the timing pointers are rarely accurate and that timing chains vary in stretch or lack of it, we adjust that cam by ear. It's a bottom end cam, probably the best grind ever for a truck or even a car stoplight to stoplight, which has a low rpm, smooth idle. You'll know when it is right if you listen. Our final adjustment is the highest idle RPM at which it will still bump start. You can find this in a few tries with someone in it who can keep test starting it. If it starts with just a bump of the starter and idles good, advance it a bit more until it balks and back it up to the last place it started instantly. You're closer than a light will typically get you. To verify start at 10deg BTDC and do the procedure. Once your ear and the starter is satisfied check to see where the timing ended up and note it, maybe with chalk or some other marker on the indicator. It could land anywhere from 14 before to 9 before. But timing indicators aren't precision, so if it runs and starts right, it is right. Once marked you can use a light next time, unless there are a lot more miles on it and the timing chain stretches some, which is predicitable. good luck Duntov
Melling Chase was created in 1991.
Does the 1991 2.5 s10 have a timing chain or a belt or just mesh gears and how do you replace them The camshaft is gear driven off the crankshaft. The camshaft gear is pressed onto the camshaft. The camshaft must be removed from the engine to change the camshaft timing gear. The timing gears should last the life of the engine. Next time, please don't answer your question with another question.
On the 3.1L & 3.8L engines, the CMP sensor is located on the timing cover, behind the water pump, near the camshaft sprocket.
The 1991 Mitsubishi Mighty Max with a 2.4L engine features a timing diagram that indicates the timing marks for the crankshaft and camshaft alignment. Typically, the crankshaft should be aligned to the "T" mark on the timing cover at top dead center (TDC) for cylinder 1, while the camshaft timing mark should align with the corresponding mark on the cylinder head. It's essential to ensure proper alignment during timing belt installation to maintain engine performance and prevent damage. Always refer to the vehicle's service manual for specific details and illustrations.
On the V6 its in the block between the two heads and right behind the timing chain
getting the marks aligned correctly is important to insure the amount of power you will have.
Yes it is
The camshaft position sensor on a 1991 Acura Legend is located at the back of the camshaft, near the rear bearing cap. It monitors the rotation of the camshaft and relays this information to the vehicle's computer.
The top cam sprocket is aligned with the notch on the head. The bottom camshaft crank pulley is aligned with the notch on the oil pump.
To replace the timing belt on a 1991 Plymouth Acclaim with a 2.5L 4-cylinder engine, first align the timing marks on the crankshaft and camshaft. The crankshaft timing mark should align with the 0-degree mark on the timing cover, while the camshaft sprocket should have its mark pointing straight up or aligned with the mark on the cylinder head. Ensure that the tensioner is properly set before installing the new belt. Always refer to a repair manual for specific details and torque specifications.
Yes, A 1991 civic uses a timing belt, not a timing chain.
To change the timing belt on a 1991 Eagle Talon, first, disconnect the battery and remove any components obstructing access to the timing cover, such as the air intake or engine accessories. Then, align the timing marks on the crankshaft and camshaft, remove the old belt, and inspect the pulleys and tensioner for wear. Install the new timing belt, ensuring it's properly tensioned and aligned with the timing marks, then reassemble the components you removed and reconnect the battery. Finally, start the engine to check for proper operation.
