    i started to have overheating ack of power problems with my escort. i was under the car and I saw the harmonic balncer wobble around. i removed the holding bolt and it fell off with the woodruff key. both balancer and key are damaged and so it crank snout. I need a new key wihich i was gonna weld either jb or metal weld and put a new timing belt and water pump and drive it until it breaks and then scrap engine as it has 140k and a bet should last 60k every where ive gone does not have that key i have even checked dealer where do they sell them ive check crquest advantage autozone advanced i dont want to g bone yard for such a little peice

    New balancers usually come with a new key. Since you mentioned the balancer is damaged, I'd suggest just spending the money and buying a new balancer.

    When I bought my new balancer it didn't come with any key.

    Try NAPA or a hardware store and try to match up your old one.

    Must be just certain replacement balancers that come with new keys. The last balancer I bought was a Dorman balancer from RockAuto, and it had a new key in it. I just assumed that all new balancers came with a new key.

    If I needed a key I would either visit the NAPA outlet, or call an automotive machine shop - and if they dont have them, ask them where they get them when needed.

    I dont want to discourage you - but if the key slot in the crankshaft is damaged, I dont think JB weld is going to hold up very long. To make it last longer, I would avoid large throttle openings, especially at high rpm's.

    That toothed 'cog' gear on the crankshaft is called the 'crankshaft sprocket' I believe. I bought a new one from a local Ford dealership in Fairfax VA for $23. I was so happy at the low price that I bought an extra one in case the next next Escort I rebuild needs one. (I was changing my 91 Escort LX from the flat toothed belt of the very early 2nd gen. Escorts to the round toothed type of belt used from April 91 onward).
    I called several auto parts places, and the only one who said they had it were asking $70 to special order it; and they didnt have a picture of it in their computer. I didnt try to get one from the junkyards either, because they are pretty hard to get to when the car is sitting in the weeds minus its front tires: And once the junkyard has pulled the engine from the car & has it sitting in their shed, they usually wont sell parts off of it - only the entire engine.

    IF/When you try to pry that crankshaft sprocket off of the crank, remember that the outer rim will break VERY easily. Its almost like glass. Normally (with an undamaged keyway and no corrosion on the crankshaft or inside of the sprocket) that sprocket can be wiggled off the end of the crank by hand. Its not supposed to be a press fit but there isnt more than .001" clearance either. On one engine I worked on it came off by just wiggling it clockwise-counterclockwise with my large channel-lock pliers. On another engine I rebuilt, I spent hours prying it off by driving steel wedges down behind it. The engine would have to be on a bench in order to do this.


    Im assuming your Escort is a 92 or later. The fEscorts engines in the first part of 1991 (up through Apr. 1 92) used a timing belt with flat cogs - and the sprockets and water pump had to match. After that they went to the round toothed belt & matching sprockets - which seems to be less likely to lose teeth.

    If it's what I'm thinking of (little steel rectangle that fits in the slot in the crank) you can get them at lawn and garden shops since almost all mowers use them. They should stock various sizes and they usually sell it by the foot because its so cheap. Just cut it to length then with a dremel and de-burr the ends.

    Its a woodruff key so keystock won't work.

    I found a replacement key at an Auto parts store . An old school store, not a chain.

    They had a bunch of drawers that had different keys. I think the replacement key was a Dorman too.

    I think it was two bucks...........good luck
