98 aprilla pegaso cam timing

It's on TDC so align marks on cam shaft and crank shaft with center of cam & crank shafts and the ECM will go from there. so you will have to change the timing chain if its loose or worn out.

The timing marks are at 12 o'clock on the cam shaft pulley and at 6 o'clock on the crank shaft .

• You want to align the Crank and Cam gears timing mark with the corresponding mark on the engine itself.

• Camshaft Mark ---

• Crankshaft Marks.

• Here is your firing order

• Hope this helps.

You have to adjust the cam or cams depending on rather or not its a dual over head or single cam motor, with the marks on the crank shaft and oil pump pulley. You can get the timing mark diagrams from a chiltons book or off of Mitchell online. The only problem with mitchell is you have to subscribe to it. The timing cover must come off, the crank pulley also has to come off. When you get to where you can see the timing belt and gears you put the bolt for the crank pulley back in the crack shaft and turn the motor over manually with a ratchet and socket about 5 times until the marks on the cam or cams line up with the mark on the crank shaft and oil pump. If your car is not vtec then the oil pump pulley will not have a mark on it. This is something that probably needs to be done by a shop with technicians who have done it before. It can be a little confusing trying to do it yourself if you have never tried before. I hope this helps. What makes you think the car is out of time?

There should be a mark on your crank somewhere. TDC is usually 12 o'clock. Straight dead center up top in the middle. You can also check by pulling your number one spark plug out. Put a piece of wood into the shaft. When it goes up to its highest point, your on TDC. You have to make sure it is on its compression stroke and not the exhaust stroke. It is much easier to just align the marks on the crankshaft. There should be a mark on the teeth of your timing belt. You will have to remove the cover to tell. You have to align the mark on the crank with the mark that is at 12 o'clock.

Here is the trick. Align marks. Put the timing belt on the crank shaft pulley first, and after on the overhead cam pulley. Release tensioner and rotate the crank shaft till the timing belt makes two full circles. Try to align marks, you will be at least one tooth off. Align the crank shaft on the mark, and find out how many teeth you are off at the cam shaft pulley. Count the teeth. Remove the timing belt from cam shaft pulley only. Move cam shaft pulley in reverse according to the number of teeth you counted. Make sure the crank shaft pulley is on the mark. Mount the belt at cam shaft pulley.Rotate the belt two circles and check the marks. Repeate this procedure til after releasing the tensioner, and rotating the timing belt two full circles, the mars will be align.

You should really look in a book for this because timing marks are critical. you can damage the engine

You must find the cam lock bar and crank lock pin to do this job properly, otherwise you can bend some valves and that becomes expensive..the front crank damper has a mark to line up with a mark on the timing cover for #1 TDC, but the cam lock bar is what aligns the cams into position. The crank lock pin is helpful but not 100% necessary...

I aligned the crank shaft,,water pump pulley. and the cam shaft marks up and recheck the origninal marks I made to save time....one of the cam shafts had slipped enough to cause it to be "off time" and the computer could not correct for it...realignment of the marks and making sure nouthing changes was the solution..

You could be 180 degrees out of synch the crank pully goes around twice when the Cam shaft pully goes once.
