Crank Pulley Problem...Help Please

By tatan1106eg
- Mon Mar 21, 2011 6:39 pm #245242 Ok, I had my timing belt and water pump replaced like a month ago and last friday when I was coming home on the high way I heard a weird noise from the tire ( that's what I thought) and my alternator light came on, also my power steering stopped working. When I got out of the highway, the temp went up a little more than normal and the RPMs were going up and down from 1000 to 15000 when I stopped at a light.
So when I got home I opened the hood and the alternator belt was missing and my power steering belt was loose. I looked down the engine and the Crank Pulley was hitting against something and it wasn't rotating straight. Also, my idle RPMs were like at 1100.
Today I tried to take the Pulley out and it was so loose I took it out with a regular wrench, but some of the small (teeth) in the inside were broken and the pin was missing. I am going to replace it and would like to know if this will solve all those symptoms?
any other thing that can be bad?
Also, when I started the car today It started to surge between 1500-2000 Rpms. And after I took the Pulley out I started it and It had some clicking coming from te engine.
What can It be?

Since the teeth on the bottom sprocket are missing you need a new one along with the Woof Ruff Key from HONDA... a new bolt to hold the pulley down and new alternator and power steering belts since they might have been twisted all sorts of weird ways. Since you said you can see the Crank pulley moving in a weird NOT STRAIGHT motion. your timing belt might have skipped a few teeth, giving you that weird idle and of course the clicking noise from the engine..

who did the work for you. they did a bad job and it should be held upon them. if a shop did it..

That crank pulley bolt is supposed to be tightened to 134 Ft/LBS which is pretty damn tight...

- Mon Mar 21, 2011 10:14 pm #245287 Yes, I know that, when the guy who did that for me got the bolt off, he had to use a compressor and I wasn't there when he put it back. . He is kinda my friend but I will never go back to him. So, I will have to buy both belts (alternator/ power steering), the key from Honda and the pulley. Anything else I would have to buy?
And besides putting the belt back on time, anything else I should do?
THanks alot

What engine is it that you have? Just have to make sure everything is at TDC when you put everything back on.. the crank pulley should only be able to go on one way because of the placement of that little wood ruff key..

And if I run the car without the pulley, will the timing belt break, go out of place?

- Wed Mar 23, 2011 8:03 am #245614 Wait ... what? You want to run the car without the crank pulley. Please explain what black magic you will be using, because that would be a nice bit of weight savings on the rotating assembly.

- Wed Mar 23, 2011 1:21 pm #245649 no, read the post. The thing is that my pulley broke, and I need to get the car to the mechanic to replace it. I'm just asking if its possible to run the car without it.

- Wed Mar 23, 2011 1:44 pm #245650 With no pulley you won't have power steering and no alternator charging your battery. So you might make it 10 miles before you totally drain your battery and your car dies.

- Wed Mar 23, 2011 4:00 pm #245664 If we are in fact talking about running the car without the crank pulley ... it is impossible. The timing belt also attaches to the crank pulley ... which makes the cam spin. You have to have the pulley on the crankshaft for the car to run.

- Wed Mar 23, 2011 4:31 pm #245667 Ok, thanks.
I went today to get a pulley from a guy. The one he had for the 1.5 engine was only for two belts, so I did not buy it because I need A/c. However, he had one from a 1.6 engine which was for the three belts but it did not have the holes that mine has and it had a Huge Hex around where the bolt goes.
Will that pulley work for my d15b7?

The pulley with the holes is the old style and I've never seen that on a 92+. The one with the hex is the correct one.

The timing belt isn't attached to the crank pulley. It's attached to a sprocket behind the crank pulley. You could probably put the crank bolt on to hold the timing belt guide and limp the car. I've never even considered doing that but off the top of my head I can't think of any reason why not. Although as teal said, you wont get very far w/out an alternator belt.

- Wed Mar 23, 2011 4:43 pm #245678 Thanks alot. So I should probably buy that one then.
I wish I could make my "friend" pay for it but I just barely talk to him anymore and I just dont want more problems than the ones my car has given me.

Not true, the timing belt runs on a separate cog pulley behind the timing cover. The crank pulley is on the outside of the timing cover :thumb:

The crank pulley serves as a balancer and drives the belts to the accessories.

I speak from experience... many years ago when I first got into hondas, I put my motor back together after changing the water belt/water pump and remember finding this tiny piece of rectangle metal on the floor under the jack stand.
I had no clue it was the woodruff key, or what that even meant.
Fast forward to 6-12 months later, I was driving on a 4 lane rt. and my car started vibrating. I looked at the dash and my battery light was on. I started looking fr a place to pull over and "bam clunk ding" I saw something in my rear view rolling off the road.
I shut the engine off and coasted over and popped my hood to see all my belts just chilling hanging in place but no crank pulley! I never found it in the ditch so I figured I'd see how much closer I could get to home or even a friend's house before the battery died since I was 15-20 miles away.
Driving with the radio off, I made it pretty far. About 1 mile from home the gauges quit working... ended up pulling into the driveway with the car starting to run rough (weak spark I assume). The battery was DEAD!

That's how I learned about the woodruff key... the same way the mechanic in this thread did. :lol:
