Good morning Kevin,

I hear two noises.
The squeak is, I think, a dry bearing in your fan pulley or the belt is slipping. Did you replace the belt by a new one?? Spray WD40 on the belt and see what will happen. WD40 on the pulley will stop the noise for a short time, it will need grease. If you listen closely you can hear it cry :Grease, Grease? Grease.
The second noise is you starter crank touching the pulley pin. Just pull the crank away from the pulley.

I believe Andre is dead on. Kevin there shouldn't be just a nut on the back of your fan shaft - the correct item is threaded but it's the base of a grease cup.

Doesn't have to be a brass one but that's what it should look like. Might should also pick up a crank handle spring to keep crank ratchet pushed forward away from the motor.

As a side note, the initial exchange in this thread is one of the things that I like about this forum. Someone in New Zealand posts a question about an engine noise and 47 minutes later, someone in Belgium posts an answer (which is then confirmed by someone in the United States). Ya gotta love it! :-)

Thanks Guys I'll check those areas and see if your right.
Dick your bang on, its the best part of owning a T, I have all these friends I've never met with so much experience its such a help.

I will post results after I check it out....

Kevin, the nut holding your fan shaft to the arm is correct for your application. Seth's photo is of the earlier type, which is lubricated with a greaser from the rear. Your aluminium pulley will have a brass threaded plug which is removed and then oiled. The fan is lubricated from the front.

Dry bushes will certainly squeal! If you need to replace them, make sure you have a good running clearance. The oil needs to get to them.

Hope this helps.

Allan from down under.

Maybe my ears are getting old. The only noise I heard was a possible exhaust manifold gasket leak. Kind of a tut tut tut tut. I didn't hear any pulley squeak.

Some more to check, the dry squeal could be the generator brushes, and maybe the crank pin on the front pulley is floating a bit as well.

There is a high pitch squeak Norman maybe the video doesn't show it right.
I sprayed the belt with no advantage.
Frank it had a strong noise coming from the Genny bushes when I first got the T and cleaning it up cured this so you maybe your on the right track but Alan I have placed a stethoscope on the Genny, fan hub etc and can't find the source using this method. I sprayed a bit of WD40 into the Genny as it was spinning and see how that goes.

Kevin, have you tried running it with the belt removed to see if the noise goes away?

Hi Kevin. I had a noise very similar to this, on my Model A, that drove me crazy to the point that I thought I had run a bearing. I did all the same things as you with the fan, belt, generator and engine mounts. It was so loud I had to wear ear muffs while I was trying to find the source. I finally found that the gasket between the carb and manifold sucking air. I traced it by spraying CRC/WD40 on the joint. It's simple to check and worth a try. Andrew (Kapiti)

Funny you say that Andrew as I tried getting my ear around the engine without getting close to the fan and I felt it was louder down there. I did spray around the area as suggested but maybe the leak is underneath on the join?. Will try there, thanks.

John I could try that as it will remove doubt from that area.

Andre I had a noise the odd time like a loud tinny clunk and I though it sounded like something was getting picked up in the trans. It only happened twice after cornering and I think you may have solved it with your crank handle advice. I adjusted the spring and refitted the end into the small hole and it hasn't done it again...yet.

So with a new gasket it's quiet, or were any flanges warped?


Top of pagePrevious messageNext messageBottom of page Link to this message  By Kevin Weeds on Sunday, January 24, 2016 - 04:11 pm:

Roger I haven't changed it yet, its only been a few weeks since I fitted it so the gasket should be ok but I will remove and have a look.
I'm pleased to have found the source as it was a tricky one.

New gasket plus a thin layer of Gorilla snot each side of the gasket has done the trick. Slight marks of the carby face, both flanges looked to have straight edges.
Thanks Guys

I love the fact that after years of getting advice and help off this forum, I have finally been able to repay the favour.

Thanks Andrew.
