Not necessarily--- if there is a rubber bond in the harmonic balancer and pulley the it may indicate that the pulley is slipping on the rubber
The question to ask is --is the motor running and starting ok
if so then the timing is right so look else where for the fault and the balancer is a good place to start

I put the distributor in It it is Pointing at number one

Was number one piston on top dead center of the compression stroke? Was the timing mark on the harmonic balancer at 0, when it was at top dead center of the compression stroke? Try again.

TDC or 0 degrees timing advance will have #1 piston at the top of the cylinder. The timing mark on the harmonic balancer or crank pulley will be on the 0 reference mark.

When setting the ignition timing on a 1991 ford ranger 3.0 were dose the rotor need to point, after number one or before number one? the engine is on top dead center

The engine timing markers down on the harmonic balancer/crankshaft pulley should be aligned with the timing indicator on the engine block to "0" degrees when the engine is in the compression stroke for the #1 cylinder, and this is TDC or "Top Dead Center". When something blows out of the spark plug hole that only means that the piston is coming up on TDC, but the crankshaft will still have to be turned until the timing markers are at "0" degrees. You should be sure that you do know how to properly align the timing marks to "0" degrees, and the timing marks must be set at "0" degrees before the distributor can successfully be installed.

Be certain that the timing marks are set at "0" degrees and on the compression stroke for the #1 cylinder, or the timing will be 180 degrees off when you install the distributor. This has to be precise and guessing will not get the distributor properly clocked in so that the ignition timing can be correctly set.

Once you are certain that the timing is set to "0" degrees "TDC", then mark the distributor housing where the #1 position on the distributor cap will be when the cap is installed on the distributor, so that the distributor housing shows a reference mark where the #1 position is, then the distributor should be installed so that the ignition rotor is pointing directly at the #1 position on the distributor housing, or just before the #1 position mark according to the rotation of the ignition rotor. The distributor should be able to turn and point the ignition rotor on either side of the #1 position mark to provide plenty of timing advance or ****** so that the ignition timing can properly be adjusted to specifications after the engine has been started.

Be sure that you follow the proper timing procedure for that vehicle and remove any timing spout connectors that are described in the set timing procedures

Also, be certain that you are actually using the #1 cylinder to set the engine to TDC and to actually time the engine with a timing light. Here is a firing order diagram that should also help to assist you. Let me know if you require any further assistance.

Timing mark problem. 92 jimmy.

Get a piece of sand paper or a wire brush it wont ware the numbers off they are engraved/stamped on there.
If not you can try timing it by ear just loosen your distributor and make small adjustments after each adjustment take it for a drive you will know when you got it right.

Timing belt broke and jump timing how do i get

If you have the harmonic balancer still attached you can align the timing marks with 0 degree to get the main block aligned. With the head removed you can turn the cam shaft till the number 1 valves are both closed and the number 3 exhaust valve is open. Take the time to inspect the valves as well. This vehicle did not come with no contact valves so when the belt broke it is possible the valves made contact with a piston and bent. I highly recommend you get the Haynes Repair manual on this vehicle from the local auto parts store as it has detailed instructions on how to get back to TDC if this happens. It also has Pictures on this. Because this belt goes around 3 timing marks aligning those after you have the pistons at TDC if you align the timing marks on the different sprockets/pullies the timing for teh valves will be correct.

How do i set the timing on the balancing shaft(just replaced the belt) of a 1995 misubishi rvr 2.0L sports gear

1- Take off all spark plug so you can turn the crankshaft easily to align Top Dead Center (TDC) . 2- Take off the engine cover to see the notch mark on the cam shaft. 3- Turn the crankshaft until the mark on the pulley match with the 0 on the timing mark. At this point if the mark on the camshaft all align then you are good. If it is not then you have to take off the timing belt to do the correct alignment as following items # 4 to 7. 4- Turn the crankshaft until the Piston # 1 is at top. Put in a screw driver to make sure it is at the top. Make sure the Crank shaft at 0 mark. If not, keep turning until it is at desired position. 5- Turn the camshaft to align at the mark in the straight line with the crankshaft mark. 6- Make sure the camshaft lobe is not pressing to open the intake or exhaust valve for piston # 1. This is to ensure it is at ignition stage: Piston is up, all valves closed. 7- Once everything is aligned at TDC, put the timing belt on. Tighten the tension adjuster, then you are good to go.

Timing setting

No it should not make a differance considering the engine will be constantly rotating, because the engine must be on and at normal operating temperature to set the timing.

I have a 1985 motorhome with a big block 454 chevy. the timing is way off the 4 degree mark & was told by my smog tech the balancer had slipped. replaced the balancer but still can't set the...

Helicoils will not harm the balancer. So, forget that. First, I recommend that you determine true top dead center by placing a drinking straw into the #1 plug hole and turning the engine by hand till the straw is at the top of the piston stroke, then back off a short distance, remove the straw, and insert a bolt several inches long, the exact thread size and diameter as the ones on the sparkplug, down into the plug hole, far enough so that it contacts the piston, then back off a bit (using fingers only) then, turn the engine slowly by hand till the piston again contacts the bolt. Use a crayon and make a mark on the balancer using 0 on the timing tab as a reference point. Spray some paint on the exposed bolt threads so it can be re-installed at the exact same depth again. Remove the bolt and turn the engine backwards by hand and again insert the straw. when it nears TDC again, put the bolt back in, using the paint on the threads as a guide as when to stop, and continue turning the engine till the piston again rests against the bolt. Make another reference mark as you did before. The two marks will be about an inch or so apart. Exactly half way between those marks is true TDC. If it is anywhere other than where the factory mark is, use a hacksaw to cut a permanent line into the balancer and use white paint to mark it. You can now time the engine using the new mark as an exact reference.
I actually have made a tool for this by breaking off the ground strap and electrode also removing the entire porcelan top as well, from an old spark plug and tapping a screw thread into the empty shell, then placing a bolt into the shell rounding off the top so it is less likely to mark the piston top. Never turn the engine by any means besides normal hand/wench method and never force anything. The entire operation actually takes longer to write than it does to do.

Need to know to line the notches up and time the car

First you need to remove the number one cylider spark plug and find out when the piston is at the top of its stroke on the compression stroke. This is callled top dead centre (TDC). The timing mark on the harmonic balancer should be at 0. Then you need to follow the number one spark plug wire to the distributor and that is where the rotor should line up when you put the ditributor in the engine. This will result in 0 degrees of advance. The car should run and using a timing light, you should be able to set the timing to the factory specs.

I have a 1995 jeep grand cherokee. we put a new motor in it but i can't seem to get the distribtor timed with the timing marks

Which engine? Just a generic answer is that the damper on the front of the engine may be your problem...Sometimes the outer ring moves on the inner rubber insert. If this happens and you need to establish timing, there still is a way...use a bolt with the exact same thread as your spark plugs have, dress the end so it is rounded on the end.Turn the engine by hand till you can see the piston. Install the bolt into #1 spark plug hole,so it extends into the combustion chamber. Turn the engine by hand till the #1 piston touches it. make a mark on the damper exactly at the "0" mark on the scale.Remove the bolt and turn the engine backwards till the piston is again visible, install bolt again and turn till it touches the bolt again. Make another mark, again at "0".. Remove the bolt. Measure the distance between the two marks you made, divide it exactly in half and this is exact top dead center. Make a mark there and use it to time the engine.
WARNING: Do not turn the engine using the starter, or use any excessive force when turning the engine or you will do damage to either the piston or valves.It is best to install the bolt after you are visually close to top of piston travel (look through plug hole till you see the piston) to avoid valve contact.
You can "save" a pulley with a migrating ring by drilling and tapping
a 1/4" hole 180 degrees apart, through the outer and inner rings
You need to use exactly the same length threaded rod installed into both holes to keep ring from moving again. Use loctite to prevent the rod from working loose.The balancer is balanced...using different length rod will throw off that balance. I cut a scredriver slot into end of rod to aid in installing. Holes must be exactly at 180 to retain balance as well. You may also have the distributor a tooth off, so make sure that's correct as well.
Good luck!
