The best way is remove spark plug number one turn the engine manually untill the piston is al the way up your timing mark should be at 0 if not turn untill its at 0 remove distributor cap and the rotor should point at the number 1 cylinder if not the distributor is at the wroung place 2 choise remove the distributor and put it so it polnt at the number 1 on the distributor cap or simply start your firing order to where the rotor point

Depends.
If you have tdc on the number one cylinder, and it is tdc on the compression stroke, then the rotor should be close to cyl one.
A four cycle engine has four up and down strokes, compression, power, exhaust, and so on.
Depending on the make model and year, the firing order could be 1-3-7-2-6-5-4-8 which would mean the timing chain or the distributor is one cylinder too far advanced if it is pointing to number 8.

IVE GOT TDC on #1 now do I put the distributer rotor pointing toward #1?


It depends which tdc ... Remember that the piston will be at TDC on both the compression and exhaust stroke.

If you turn a distributor to point the rotor rotor arm at no 1 terminal on the exhaust stroke, your timing is 180 degrees out.

Other wise yes, point the rotor arm at No1 terminal.

To check which TDC it is.. place your finger over the no 1 spark plug hole and get somebody to turn the engine for you. You'll feel the compression build up.

I'm working on a 99 blazer v6 4.3 L . It's out of time.I won't start how do I set the engine back on time and what's the sequence of such procedure?


Juan, you need to look for timing mark on crank shaft pully just below water pump,you will see a deep cut mark, turn over motor BY HAND disconnect battery,for safety , now remove # 1plug when you rotate motor you should feel compression , as piston comes up ,if you don't feel compression rotate motor 180 deg,as timing indecater alines with crankshaft timing mark, that should be (TDC) top dead center ,now set plug wires in firing order.make sure when starting that you have spark, if it wont start try resetting timing again, you may be 180 deg out . I hope this helped if it did let me know.

Replaced distributor and new one would not line up. Lined up rotor as best I could and tried to start. Ran rough and horn beeped twice!. Removed, put at TDC and lined up rotor with #1 plug. Now engine...


wow the engine timing is definatly off. first things first are you sure you have correct replacement distributor? you may have the timing 180 degrees off, the easiest way to set tdc is remove #1 spark plug insert long handle screw driver and then line up 0 degree timing mark on crank shaft pulley to timing cover while watching screwdriver to raising as high as possible, this is ensuring that the #1 piston is all the way up. now you are surely on tdc. at this point remove distributor cap and se what cylinder # the rotor is pointing to. the firing order is 1,5,3,6,2,4 with the rotor moving in a clockwise motion here is a picture to help.cables.jpg if the rotor is not pointing which i doubt it will be remove distributor and re install with rotor pointing towards cyl. #1. hopr this was helpful if so please rate positive.

Nissan ca20 e distributor replacement. How do I replace dizzy in correct timing to line up with tdc


if you take old dizzy out,wherever motor is stopped,just put new one in,taking note of position of rotor,to where the old rotor was pointing.pick a spot on the motor or bonnet when you first take cap off,to where rotor is pointing,then note where dizzy sitting in relation to clamp bolt.OR,get timing pulley on TDC,then note where rotor pointing

I have a 1972 Jeep CJ5, 304 V8 somebody decided to take my distributor. I have a replacement but don't know how to install from scratch wires and all. When they say rotor should point towards #1 cylinder...


Hi:
What they mean is that the rotor should point towards the spot on the distributor cap that the #1 spark plug wire attaches to.

So the basic process is this:

It is easiest to do with all your spark plugs out, but at least remove the #1 spark plug. rotate the engine till the #1 piston is fully up on the compression stroke( TDC or top dead center) and verify the timing mark on your crankshaft pulley is where it should be. Then install the distributor with the rotor pointing to where the #1 spark plug wire hooks up to the cap. This will get you close to the final spot, and that will work for you. Just be carefull not to get it off one tooth on the distributor gear, as you might still think it is close, but the distributor will have to be rotated to the extreme adjustment to get the timing close.

Hope you get it back together!

My cam shaft timming gear and my crank shaft timming gear dots line up and my harmonick balancer timming mark is on 0 which way should my rooter button face towards number 1 or towards rear of engine


The rotor should be pointing close to number 1, but keep in mind that the spark is actually supposed to happen before the piston gets to tdc so the rotor will be a little bit past the number 1 terminal when the crankshaft indicates that you're at tdc.

Double check your timing, you could be off 180 degrees. Remove the valvecover on the driver's side and watch the valves as the engine comes up on TDC. The intake should open first and as you pass TDC the exhaust should start to open. At that point your rotor button should be in the 5 o'clock position for #1 plug to fire. Firing order should be 1-8-4-3-6-5-7-2 and it goes clockwise from 5 o'clock. Hope this helps.
