Anybody run a fan belt that is not wrapped or a cogged belt. Mine developed a squeak that wasn't consistent with valve train noise nor crankshaft or rods.I have all three fan pulley, crankshaft, and alternator new with about 1500 miles on them. They look new. I never have had luck with the wrapped belts. Any suggestions?

First, to insure it is the belt that is squeaking, remove it and run the engine to see if that is the problem. If it is, you can use soap or belt dressing to help remove the squeak, or just run the belt a bit looser.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command! -
Already ran it off the engine. Look at the pictures Wiz. It's falling apart. The alternator pulley is just too small diameter for a wrapped belt. I need a cogged belt. I bought one from a place last year online for my truck, a cogged belt and it works perfect.Comment

I actually have one from the auto parts house, narrower but works fine for my alternator. I just took a string and measured around the pulleys and got 3 different lengths, used the one that fit, took the other 2 back.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!Comment

Ok, who is your auto parts house? Is it a cogged belt?
I think I found the place I ordered from the last time for my truck. $2.38 each. Shipping is more than the belt. I can't drive to a parts store that has one for that much. I'll post back when I get it and try it out.Comment

The cog belt is a better choice when running an alternator. The gates # BX40 or BX42 works nice
Fwiw ,,,,i don't like to use any belt soap or dressings as the noise usually gets worse or is temporary at bestComment

Belts are sold by Car Quest now bought out by Advance Auto Parts here.
These belts are for trucks and are a little wider than some and work well with the wide pulleys on Model A.
The notches allow belt to go around the small pulleys on alternators without damage to belt.
A notched belt is good idea on Alternators as it wraps tighter and slips less I think.
Notched belts use a different number system
Truck and Bus Series made by Gates
This one fits the smaller alternator pulleys ... smaller than the ones on a stock Chevy V8 alternator
Numbers on label are:
TR22425
15A1080
11/16ths by 43-1/8th
They are NOT wrapped and are cut rubber on the part that goes into the pulley groove.

You can also hit it with a squirt from WD-40, will stop the squeak immediately if that is the issue. Usually the belt is worn, thus riding inside the pulley not on top where it belongs.Originally posted by DaWizard View PostComment

I have used the BX40 with good results for many years. The internal cogs let it curve around the small alternator pully nicely.Comment

I'm running an alternator with a 2" pulley. What is the recomended fan belt?03-18-2021, 07:17 AM -
Thought we might talk about the change from the FLAT Model T belt, to the "V" type belt. START THINKING!!!07-10-2017, 01:49 PM -
I am trying to find a fan belt that will fit my 29 phaeton engine I am restoring. I have a couple fan belts that are 43 1/2" measured on the outside. They are too short to install. Maybe if I took the powerhouse generator pulley of they would fit, but I would rather not have to do that. I think I need a 44" fan belt. It appears that parts suppliers only sell 43" belts. I checked...01-31-2021, 09:40 PM

I was detailing the engine compartment on a 29 Tudor that I have been restoring for a friend and I noticed that the fan belt was touching the lower radiator hose. I thought at first that the belt might be incorrect or old and stretched out. So I grabbed a new one off the shelf and it seems to be the same length (both belts have a "G 07" mark) . Can I buy a shorter belt somewhere?You do not have permission to view this gallery.

I have been working on my 29 pickup and ordered parts from SNJparts.
The fan belt was to long and I had to build a bracket that raised the generator above the lower radiator hose and tube.
I have 5 other antique cars and find dedicated part stores sell parts that do not fit and they know it but they continue to sell them.
If I purchase parts from a local store I can always return...07-25-2021, 04:26 PM -
non authentic . But would anyone have approx diameter and width of a pulley to use on a GM Alternator. I can order one from vendor but because I am on the ass hole of the planet its 3 weeks delivery , just wondering if guys are using a pulley from some other application that I can get locally. thanks04-10-2018, 08:39 AM -
I have decided to change my generator or for a alternator on my 1930 Model A. My question is: What is the best belt to buy for my new alternator? Is one better than another? Thanks Hugh03-08-2019, 06:32 PM -
I am trapped with one car in Florida (with my Les Andrews Red Book) and one in Georgia. I think that my question would be answered with the book. I am working on the one in Georgia and need to buy a fan belt. Can anyone tell me the size and if I can just get this at an auto parts store?06-21-2017, 11:11 AM -
