Ok so my 94 2.3L Ranger broke down on the way to work this morning. I got towed back the house and and discovered my timing belt broke. I got the link on here for replacing it, but my question is, how do I verify that my piston #1 is at TDC?
Any other helpful coment would be greatly appreciated as well. Thanks in advance.
Welcome to FTE junkstan95. Im glad you chose the best site on the net for Ford-Trucks! See you around the boards!!
you can turn the motor over with the starter. have someone bump it and put your thumb over the spark hole. when it gushes and pushes your thumb off you should be on tdc when you align the timing marks on the dampener. this will get you to the correct stroke

Since he is re-timing the cam, the stroke doesn't matter on the crank, just TDC. Matter of fact, without the timing belt on it, he probably won't get compression on #1 anyhow.....
You will have the crankshaft pulley off anyway. The key that holds the pulley in place is called a Woodruff key. You want the slot that holds this key to be straight up. That will get the piston very close to TDC, close enough for timing purposes. jd
I always moved the crank to TDC before I removed the pulley and cover. There is a pointer on the cover. And yes the Key Points straight up. Also it cannot be off 180 degrees if the timing belt is broke. Tdc is tdc it can only be off 180 if the timing belt is on. Compression tdc or exhaust tdc is determined by Cam position.
Align all the marks and make sure nothing moves when you let the tensioner tighten and you should be good to go. I would advise replacing that tensioner.
i dont mean 180 degrees i mean one cycle off.. if its on the top it can be on tdc or one cycle off

Matt, the cam turns 1 revolution to the crank turning 2 revolutions. But, in this case, you are aligning the cam to the crank, so you can't be on the wrong stroke (or cycle as you put it).
ok guys while your on the topic, Is there a mark on the timing belt cover for the mark on the aux sprocket to line up with on an 89 ranger 2.3???? I cant find one, Should it be on tdc along with the crank pulley mark. Does the aux have a shaft that turns another sensor?

if the belt broke that means the cam wont turn, if you go turning the crank the valves arent opening and closing like they normaly would with the cycle, if you not carefull you can damage a piston.
