Front 60K question

There is a metal washer that goes with the Timing Sprocket. My question is, does the concave part of the washer face the block (inward) or does it go towards the sprocket?

:thankyou:

out. towards the balancer, or else it would cut the belt.

Yes, out. Its function is to keep the belt on the sprockets.

I must have things all messed up...Does the Washer go between the block and the sprocket or between the sprocket and the balancer?

Judging by the answers I got from my first question, I believe I know the answer. I just want to bounce this off the pro's just in case....

It goes between the sprocket and the lower timing cover.

Oil pump -> sprocket -> washer -> lower timing cover -> crank damper

Sweet. Thanks for the info. Now I just have to get the rest of it back together. It's really not as bad as I thought it would be.

I had someone help me take it apart (actually, he did the work and I just watched). Now I'm getting back to assembling everything back to together.

I couldn't remember for the life of me how that washer went. Can't want to get it back together and hear it fire back up. Hopefully, I won't have any issues once it's all back together. It would suck to have to take it all back apart again right after getting it all back together :banghd:

Thanks again for all the help!!!

If you forget to put the washer on, you won't hear anything out of the ordinary... until a while down the road when you start hearing an odd squeaking noise, then look down there to discover that the timing belt has cut a perfect belt-shaped hole into the lower and middle timing covers. I believe somebody posted a thread on here a while back with pictures of exactly that happening. It was pretty funny!

Yea it was the guy who had this...

That "washer" is the outboard timing belt guide. The inboard guide being the shutter vane attached to the timing belt sprocket. With this knowledge, it should be clear that the outer guide must be slipped on the crankshaft after the timing belt is installed and before the lower timing belt cover and damper are installed.

Taking a close look at the "washer," you will see that the smooth side has the "shadow" of the sprocket teeth near the central hole. This is a clue that the smooth face must touch the sprocket. The outer face of the guide has a more uniform contact patch where the inboard radius of the crankshaft damper presses against it from the tightening force of the damper bolt.

I have serviced SHOs where these guides were left off by shops that didn't know or care where they go. Another reason why car repair shops can get such a bad reputation.

Thats exactally how I figured it out when I did mine for the first time. Maybe some people are just afraid to think for themselves.
