Model T Ford Forum: Forum 2012: Fan pulley on crankshaft
Top of pagePrevious messageNext messageBottom of page Link to this message  By Mack Cole ---- Earth on Sunday, August 19, 2012 - 05:44 pm:

I have shimmed the pulley on the crankshaft of my TT twice that I know of and it has started its clanging and banging again. I am sick of it.

I know those clamp on pulleys are expensive but will they fix the problem? Also does the starter pin still go in there as normal? Do I have to take alot of stuff apart to install it? I am thinking it wouldnt be hard to do.

Just want to make sure before I git my heart set on replacing it.

Used one on my TT and so far have had great results. My crank pin went in just like the old one came out. I had my radiator out at the time so I don't know what you would have to take apart. I would think if you don't mind working around the radiator that you could change it by just removing the hand crank, belt and pin.

I put one on our Depot Hack and it worked very well. Didn't have to remove the rad to install it. Well worth the money.

I installed one on friends car. I am glad the radiator was off. That split pin was a bugger to put in. Seems to work real well, the pulley it replaced was really flopping around. As soon as I get the money I am going to put one on mine.

I took the original pulley and ran some brazing on the inside of the hole where it fits on the crank. The pulley was then bored out to fit on the crank. I mounted the crank and pulley in the lathe and turned the outside of the pulley down to make certain it had a crown and was concentric with the crank. Of course this needs to be done prior to assembling the engine but it sure was a lot easier to do it before it was on the pan. It really runs nice now!!!

Mack, if you're going to replace the pulley w/out pulling the radiator, put a piece of cardboard against the radiator to protect it and your hands.

you will need to remove the fan, the crank and crank ratchet at least. It is not hard to remove the radiator and is much easier to replace the pulley with the radiator off. I put one on mine and it works well. No more rattle and idle knock. The rolled pin is hard to install, but otherwise the job is easy.

I've installed a couple of them and it's a lot easier on the hands and radiator to remove the radiator first. They work just fine, fit like they should and stay tight on the crank.

For one non-standard application, I put one of the pulleys on a lathe and cut grooves for a serpentine belt and then use two narrow belts - one fairly loose one for the fan and a second sight one to drive an alternator. No point in putting more strain on the fan bearing than necessary.

Thanks folks for the info.
I am so sick of hearing this thing rattle.Makes me think the rods are comeing out of it or something.There should be rements of a Mountain dew can somewhere in there that was cut for a shim.

I ran 4 beads inside one w/a wire feed welder, filed the tops offn the beads a bit and that worked.
As the saying goes: "Your mileage may vary"

Does anyone have a picture or OT article related to shimming this pulley that you can post?

Shims will help for a short time.But take it from the tightest middle aged old phart on the forum,buy a pulley.
I hate spending money,aint got much to spend,but this is kinda like a gas tank,you can fiddle till you are blue in the face or bite the bullet,and wince when you make the call.

Ok,I went to the catalogs.I am stumped.The photos and discribtions are not clear as to which pulley is which in a couple of them.Sometimes like today I have not been able to concentrate and such,and my eyes are giveing me a fit.
My pulley is the 3 inch or so size.I want to order the 1 that clamps to the crankshaft.
Which part number in the Snyders and or smith jones catalog do I need to order?
The pics aint clear to me.

These are the split ones.

Unless you have a narrow nose pan the larger pulley will work, along with the correct fan belt. Smith and Jones only list one pulley that I could see and I would guess it's the later style. 1920 to 25 should work for the fan belt and maybe later for TT's.

J&M Machine web site says they make pulleys brand new. Look at the for sale page. Dan

Well,I called Snyders,got a pulley and a pair of fan bushings for the TT and installed them.It got rid of alot of noise.But if I advance the timeing a good bit I get a little engine noise.So maby I didnt git rid of all my rackets but it sure helped.

Many times the front of the crankshaft is worn too. Unless you have it out of the engine, there isn't much you can do about it.
