How do you check camshaft alignment?
Begin with the intake valve; slowly turn the crank clockwise until the lifter rises 0.050 inch. Stop turning the crank and read the degree wheel. This begins duration at 0.050 inch. If our cam card says the intake valve opens at 31 degrees BTDC, the degree wheel should show 31 degrees BTDC at this time.
Why wont my timing marks line up?
The reason the marks don’t line up after you turn over the engine is that the marks aren’t symmetrical. There are 211 teeth in the timing belt. From the bottom center mark, where the printing is, there are 75 teeth on the left side, and 77 on the right side, and 59 teeth between the top two marks.

What does the camshaft timing gear do?
The purpose of timing gears is to allow the camshaft and crankshaft to turn the timing chain. The crankshaft turns to move pistons up and down inside the cylinders. The camshaft turns to allow intake and exhaust valves on the cylinders to open and close. These components are important for proper engine timing.
How do I know if my cam timing is off?
If the engine timing of the cam is off, your car will either be running rough or not at all. If the ignition timing is the problem, it isn’t as easy to notice because it has four cycles: Intake valve sucks in air while fuel is delivered by the injectors. The fuel mixture is reduced.
Does cam timing affect ignition timing?
How does cam timing affect ignition timing? In a short, two word answer… it doesn’t. I get questions from people asking: “My cam is advanced 4 degrees, where should I set the ignition timing on my engine?” The complete answer is; Wherever your ignition timing is normally set at. Cam timing is VALVE timing.
What is the position of the camshaft when setting valve timing?
Timing in the Camshaft. Rotate the crankshaft clockwise to 90 degrees after TDC. This will make sure all the pistons are half way down the bore. Now position the dial gauge so that it can read the lift of the inlet valve of number 1 cylinder from the top of the valve retainer (see left).

How can I get TDC without timing marks?
Place a ratchet and socket on the large bolt in the center of the crankshaft. Place a finger over the spark plug hole and turn the crankshaft clockwise. When you feel pressure against your finger, the piston is coming up on the compression stroke.
How do I set the ignition timing without a timing light?
- Step 1: Get a vacuum pressure, dwell, and RPM (revolutions per minute) …
- Step 2: Loosen the bolt that holds the engine’s distributor. …
- Step 3: Rotate the distributor slowly. …
- Step 4: Adjust the carburetor.
How many revolutions until timing marks line up?
When rotating the crankshaft and turning the engine over, the camshafts will realign after the crankshaft has turned twice. Now, the marks on the timing chains will take around 15 rotations to line up on the timing marks on the sprockets.
What are two possible reasons why the camshafts would not line up?
The reason why horizontal lines on cam gears not lining up, is because there is no tension on the belt when cams are resting (engine turned off). To confirm that your timing belt is on correctly, just take (2) 14mm wrenches and apply 5-10 lbs of load on each cam gear.

What do adjustable cam sprockets do?
Adjustable camshaft gears allow you to tweak the conservative factory settings for increased power and driveability. Adjustable cam gears also give the user the ability to shift peak power throughout the rpm range, a big plus if you are a low-end city driver, mid-range autocrosser, or high-rpm drag racer.
What is the function of crankshaft sprocket?
A crank shaft sprocket is used to drive a clutch and gearbox with a chain or toothed belt, Many motorcycles have them including most Harleys but most modern designs use gears instead of a chain or belt for the purpose.
