    I'll be replacing the water pump and timing belt before Winter sets in. I hope. :?

    I have good air tools, just not had 'em long enough to really get the feel of 'em. Been using nothing but hand wrenches and elbow grease all my life.

    Anyway, I know I'll have no trouble spinning the pulley's bolt out, but what about the reinstall?

    Foul the motor and use a torque wrench or just hammer on it with the impact? LOL

    Best way to foul it with an ATX?

    Pics?

    The more I learn about my Escort, the better prepared I am to go back in time and buy it again for the first time. 8O

    If you are going to replace only the belt, water pump, etc. -- but not replace the crankshaft sprocket, or the large crankshaft pulley, or use a different bolt; then you might want to make a mark on the bolt - and on the pulley, so you know where they are set now. When you reinstall the pulley, just make sure you only tighten the bolt to the same location as when you loosened it.
    I havent heard of other people doing this, but I have used this technique a quite a few times; though using hand tools; a length of pipe slid over the end of my half-inch drive breaker bar. I also use only a 6 point 19mm socket. My air impact wrench isnt useful, as my air compressor died.
    Another way I do it on 1.9L Escorts: The pulley has 'teeth' around its rim, to provide the signal for the crankshaft position sensor. And there is a 'lip' on the bottom of the aluminum housing (oil pump) at the passenger side of the block. I have a piece of flat steel 'strap stock', about 1/4" thick by 1-1/4" wide and two feet long. I hold this so its end is resting on the lip on the aluminum housing, with its side edge in between two of the teeth on that 'tone ring'. While my wife holds that in place, I torque the bolt to about 90 ft-lbs. I have done this with each of the four Escorts I have worked on, and havent broken off a tooth yet. However I do have an extra crankshaft damper pulley in case I did break a tooth.

    That is some really good info!!!!! :cheers:

    I have no problem using torque wrenches but I'm always nervous as a cat when trying to figure a way to stop something big from turning.

    iv never met anyone who has used a tq wrence on a pulley bolt. iv always used breaker bars or impact. weather u use a bar or your impact ull be fine. i hvae only seen one bolt break ever and that was from being rusted in the crank and using a 3/4 ingersol 1500lb impact on it for 10 min.

    Y'all got me thinking on having a spare, so, I went out at lunch and picked one up. Dorman 594-033 and it HAS THE KEY!!!!!

    And, on putting just a drop of red Loctite on the bolt, this will allow it to come out again without any crazy procedure like heating or anything? One more, where on the bolt should the drop go? Leading? Trailing? Middle?

    I feel like such a noob. :wave:

    I havent used any threadlocker on mine, but putting it on the middle of the threaded portion is what I do when I use any. It will only make it a little harder to unscrew, not a big deal. Dont over-torque it. The Service manual calls for only 81-96 ft-lbs.


    And thanks for the Dorman part # for the pulley.
