Model T Ford Forum: Forum 2014: Ring noise at front of engine
Top of pagePrevious messageNext messageBottom of page Link to this message  By Gordon Drisko on Wednesday, July 30, 2014 - 09:23 am:

My 23 T started making a noise at idle, (both spark and gas retarded all the way), like a little bell at the front of the engine yesterday. I removed the fan belt and still have the noise.Took the timer off and back on, still have the noise. As I advance the spark the noise goes away.
Any thoughts. Help
Thank You

I recently had this problem also. I looked all over for what sounded like ding of a bell. The ding was slow and not rapid. I generally heard it when the engine was idling, but some times I heard on the road when the windows were open. After eliminating all the external items that could produce the ring. The one that I had thought was the problem was the crank pulley. You could strike the pulley and you could get a similar sound, but that was not it. I completely removed the crank pulley and the ding was still there. I then removed the crankcase inspection cover. I wanted to check the bearings anyway and after looking around I saw that the large timing gear teeth were full of aluminum chips. This can't be good. The front engine cover came off and more chips were found. I found that the large timing gear would make the same ding when struck. At this point I was almost certain this was the problem, but why was the gear being eaten up? The gear was removed and the cam pulled out. The front cam bearing was OK, but the bore in the block were the cam bearing fit was over sized. It didn't look like it was worn, but it was more than 0.025" over size and this allowed the cam gear to move away from the crank gear. I figure that since the cam loading is not continuous, the cam gear would pull away from the crank gear when it was pushing on a valve and then snap back against the crank gear when the valve load was relieved. This is just my theory of what was happening. I installed a steel shim around the cam bearing and a new aluminum cam gear and the ding is gone. I can't argue with success. This is not to say that you don't have an external ding. You should look as much as you can. In my investigation I found that my ignition and door keys, when hanging in the ignition lock, would vibrate and also make a ding sound. Anyway this is my 2, good luck in finding it. Isn't it amazing the sounds you can hear even over all the noise the T makes?
Mike

Loose crank pulley like Hal said. I thought it was a normal sound coming from the Anderson timer. Eventually, your pulley pin will fall out and get bent and destroy the pulley.I found out too late when my crank pulley broke. If that's the problem, find someone with and old crank with the pulley still attached and remove the pulley. Pull your rad and then install the new pulley on your crank. It is a very easy job.

I had a "Tinkle - Tinkle" sound from time-to-time coming from the front of my '19. I suspected all kinds of bad things, and pulled the radiator to find the problem in the front of the engine.
As I sat the radiator down, I heard the "Tinkle - Tinkle." It turned out to be the top, horizontal baffle inside the radiator that had broken loose - no leak - just that annoying "Tinkle - Tinkle."

I had the same ting - ting noise and found the pulley pin was loose and sliding back and forth.

One ting was produced every time the crankshaft went halfway around.

The fix was simple, I took the pin out and flattened it a little bit in the center area.

The cotter pin hole has to be aligned crosswise first and then the pin can be tapped in again.

Then the cotter pin can be replaced.

Gordon, here is a link to when I had that problem only weeks ago if you haven't seen it already.

Thanks for all the help guys! The problem is a loose crank pulley pin. I reached in and could slide the pin up and down with my finger. At low rpm it rang like a little bell on every half turn, like James said. At higher rpm it may have stayed out in one direction,or more probably the rest of the engine noise masked it! I'm going back out now to pull the radiator and fix the pin.
Thanks Again,
Gordon

gordon - Thanks for letting us know what was causing the ringing at the front of your T

You saved me from making a fool out of myself (again) by asking if you had looked to see if someone had installed a cow bell on the front of your car

"I'm going back out now to pull the radiator and fix the pin"

Why are you pulling the rad? It doesn't need to come out to fix the pin.

It makes the job really easy when you can see what you are doing. The radiator removal is two nuts,two hose clamps and a tie rod nut. Real simple,like most of the T.
No more ringing now!
