Ok had a couple of problems after replacing my timing belt last winter after it broke. 94 Escort 1.9

Car ran fine since Dec ,but developed a tapping/knocking noise .

A little searching (ok a lot) with a stethoscope led me to the balancer where I saw the keyway slot ruined so I ordered a new balancer.

My harmonic balancer was moving with the bolt tight and made a tapping noise as the engine ran.

Since the bolt was still tight I assumed that the bolt was bottomed and tight while not exerting pressure (squeezing) on the harmonic balancer and lower pully.

Took the belt back off and realized I put the lower timing pulley on backward.Flange side toward the block. Even though it said "front" right on it. A dumbass mistake.

My Question is..... Does the large washer with the key slot go on before the pulley toward the block or does it go between the lower timing pullet and the harmonic balancer?

The Ford dealer parts dept gave me the exploded drawing that shows it between the balancer and pulley.

Looking here no one mentions it.

This looks like it is next to the block.


Anyone know? The part # calls it a belt guide so that implies inside to me , but the picture shows outside. p/n E1FZ*6K297*B

P.S . I searched a ton already.

Here is the scan of the parts exploded diagram I got from Ford. The washer
in question is p/n 6K297 in the pic

The washer is called a "belt guide". The flange on the pulley guides the belt on the outside. Inside guide?

The photo from the "timing belt thread" seems to show the washer inside between the crank seal and the pulley.



Just looking to see if anyone can say ..yes it goes there....

Most of the instructions I looked at including Haynes and Autozone don't mention it.

It appears the Ford drawing is correct to me. If not what would the washer
spin againist? The Oil pump housing? I doubt it. If you look closely to the
front of the crankshaft SPROCKET you'll see a stained ring. See it? What
do you suppose put it there?

Anyway I can't definitively say myself where the washer goes. Others
here know. However, the Ford drawing is prettyt good evidence by itself.

Yes I see that stained ring. BTW the picture I posted is from a timing belt thread on this site not my car. My stuff is ruined and I am replacing the balancer, guide washer, and lower timing belt pulley w/ new parts. Expensive mistake.

The Harmonic Balancer keyway problem made a loud tapping sound that sounded a lot like a collapsed lifter. The Stethoscope told me no problem there though. Other guys that find a tapping sound after changing the timing belt should keep this mistake in mind.

Update: Put it back together as per exploded diagram from Ford and all is well.

Knocking noise gone . Several other improvements too. The new Harmonic Balancer from Ford is an updated p/n that is considerably heavier than the original. At least a pound ,maybe more. It is supposedly common w/ the later 2.0 liter engine.

Now the engine appears smoother at low speeds, particularly when the A/C compressor cycles when idling. No more feeling like the engine is being grabbed by the throat every time it cycles.

A heavier balancer is not a hi-po mod but drivability seems improved.

I later found out that Dorman makes a replacement balancer that is considerably cheaper.

After browsing the site for a while searching for a solution to my problem, I found the PCV elbow info.

Sure enough, mine was clogged and squeezing shut. I used a piece of tranny cooler hose with a clamp at the engine side to replace the elbow and now the engine idles smooth as glass.

That's it. Thanks for the help.
