Timing a 4 stroke Discussion in ' The Workshop ' started by kylespeedfightFeb 9, Messages: Rides: New Gilera Runner Hi, found out that my scooters timing is out as it has no compression to start after i undone the camchain tensioner and bolts on the sprocket, was wondering how to time it back up?

And if possible, do so while the engine is still in the frame? Messages: Engine has timing marks, line them up, you should have lined them up to start off with really mate before you pulled it apart. Todi-CorsaFeb 9, Least ya will remember for next time As a rule on most yes mate, what engine is it? Messages: 2, Rides: Piaggio Typhoon.

You have one timing mark, an arrow on the flywheel pointing to a mark on the engine case when the piston is at TDC top dead centre. Take cam chain adjuster out the barrel.

On the cam gear the there is also mark's pointing to another mark on the head. Sometimes there's two holes deg apart in the cam gear like on chinese engines and these are set then the holes are parallel with the top edge of the head.

And sometimes on honda engines the bolt fixing holes are off set so it will only go on one way. SO 1, TDC piston, 2, valves off the cam, at this time holes should be about in line on the cam so loosely bolt up, back off and re-fit cam chain adjuster.

Once all together turn the engine over by hand and check all timing mark's, then check again. If your happy then tighten it all up. And what would 1 and 2 stand for? And it is a honda engine.

I checked spark and its got a very good spark but plug is dry, i put my thumb over the spark plug hole and turned it over, and its got low compression. All gaskets are good and as far as i know the timings fine.

If its not one thing its another with this stupid scooter! Put a probe thin screwdriver down the spark plug hole and turn the engine over slowly until the piston touches it, it's a case of feeling it. Turn it over tdc and the probe will move down, turn it back, probe up then look at flywheel, the arrow will be pointing to mark on engine case. Alway's turn the engine over by hand first to check it's all correct.

If the plug's wet, get some petrol down it. Yes they could, if you have feeler gauges set them to 0. You must log in or sign up to reply here. Show Ignored Content. Share This Page Tweet.Top Dead Center refers to the piston being at the very top of its travel in the cylinder. This position is important when installing a new camshaft, because the cam must be set with the crankshaft at TDC.

If the camshaft is off by a tooth, the engine will lack power and risks damage to the piston and valves. Rotate the crankshaft so the T line is aligned with the index on the crankcase as pictured. Rotate the camshaft so that the two hash marks and smaller holes are exactly aligned with the edge of the cylinder head.

In this case, make sure that the large hole of your cam is visible and rotated away from the engine, shown in the red area box below.

Reinstall your timing chain and rotate the crankshaft a few times, double checking the flywheel-to-index and hashes-to-head alignments.

Barry and Travis You have been so very helpful to me. I know I have asked a miilion questions but you have been so helpful and patient. I really really appreciate all your help. You both are so knowledgable on the GY6 engine and Crossfire Thanks a million!!! It helped me so much! What if by chance a person removed the timing gear from the cam to replace a beating and did not pay attention to the way it came off and put it on all wrong.

Then what would this person do to time it. Getting it back on correctly is a feat not often seen. The easiest fix would be to buy a new camshaft at this point. New cams are reasonably inexpensive.

This can be done with a degree disk or a dial gauge. This method shows the degree disk which involves less specialized tools. The first step is to remove the right hand side engine cowl to gain access to the motor. Remove the 4 flathead screws that hold the sheet metal flywheel cover to the main casing. Once the flywheel cover is gone, remove the plastic cap over the central nut.

I always use a magnet to hold the degree disk in place, and since aluminum isn't magnetic, I use one on to the end of the crank shaft. With the degree disk in place you can now start the process to find top dead center TDC. You may need to cut some access holes in the degree disk face so that you can reach the inspection hole in the flywheel.

Next you need to make a pointer. An easy way to do this is cut about a " length of wire or an old coat hanger and bend it a hoop in one end. Bend the other end so that when it is mounted to the casing with a fan cowl screw, it will point accurately to the timing disk see above. Remove the spark plug and fit the TDC tool carefully.

Fully torque it down as if it were the actual spark plug. Depending on where your piston is in the bore, the flywheel may move slightly as you install the tool.

The idea behind this tool is that as you rotate the flywheel by handthe piston will not be able to reach TDC because of the bolt in the tool.

Once it hits, if you back it off until it hits again you will know the total amount of degrees between the two points which can give you TDC with a simple calculation.Why don't fictional characters say "goodbye" when they hang up a phone?
