Is the two piece as good as the original?

First hand knowledge-- Bill Stipe's one piece crank pulleys are great. You will never need another one.Alaskan A's

Mitch,
Bill's pulleys are machined from solid stock and do not have spokes. I had a 2 piece before so I don't know what an original looks like.Alaskan A's

Another 2 piece pulley failure. I was changing the fan belt and noticed quite a bit of play in the fan and upon further inspection I discovered the Bratton's crank pulley I put on about 3 years ago has pieces of the outer half casting broken off at the interlock notch. I will try the LH threaded ones that Bill mentioned to avoid a radiator tear out until the cold weather hits. Bummer!!You do not have permission to view this gallery.

I had to replace my pulley and ordered the 2 piece as pictured by JtownJoe. I have had it with the 2 piece. The new ordered 2 piece failed in about 700 miles. The supplier replaced it and in about 400 miles it failed too. Took the one piece original pulley off a spare engine and had no more problems. I found another failing pulley on a friends coupe and we replaced it with the left hand threaded 2 piece. It is a good design and no problems. The one as pictured is junk in my opinion and should not be used. Get the original one piece or the threaded 2 piece.

Did the pulley stand a bit proud of the crankshaft? It must, or the pulley will never be dead tight when the bolt is tightened.

Ya know, if this is in a keeper it would pay to put an original style one piece pulley on. If you pull the radiator, and remove the hand crank guide you only need to lift the engine a couple inches. Heck, I did it with 2 jack stands and a floor jack by meself.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

I'm not sure what you mean, Tom. Everything seemed to go in place without any issues, if I remember correctly. Is it possible that it was incorrectly installed and that is the reason for the failure? I have never had the oil pan off and as far as I know the slinger is there and It doesn't leak much oil.

If the front of the pulley is flush with the front of the crank, the pulley cannot be tightened properly, and it will chuck around in there, and loosen and crack. It needs to stick forward a bit from the crank nose
If the slinger were left off, that sometimes will allow the pulley to be too far back

Here's a solid aluminum (no spokes) 2 piece pulley from a spare crankshaft I have.
The first picture shows how the pulley stands just a bit beyond the crankshaft.
The second picture shows the wide notch to engage the two parts. It also shows very unusual wear in the seal area of the sleeve. I'm thinking someone must have turned grooves on the lathe, thinking they would improve the seal.

These odd grooves are so evenly spaced, I'm sure someone cut them on a lathe. I could make a new sleeve if I ever use this again.

Use the depth part of your vernier caliper to measure through the narrow space past the rope seal.

by plyforAm thinking of changing out the front 1 piece pulley. We used to break off the c.i. spokes to allow removal without removing the radiator, etc. I have a 2 piece pulley in the parts stash that appears well made but also researched that Sacramento Vintage Ford sells a threaded 2 piece that may be less prone to breakage, etc. Has anyone had experience with the latter, putting aside that some owners ...

The Model A shop working on my A called, prefers to install a 2 piece Crank Pulley.
Searched here and seems the 2 piece can have an issue if it can not be tightened down correctly. The fix is a spacer washer.
So if tightened down properly are there any issues? Or do I insisted on the left hand threaded 2 piece Crank Pulley?
Seems to me if there is an issue...-

by Art EbelingI told my 87 year old buddy I would put a new radiator in his 30 coupe which has overheated all summer. Of course one thing leads to another. With the radiator removed it is clear to see the crankshaft pulley is broken. Is this a one or two piece pulley and will it come off without raising the engine? Thanks, Art...

by DaWizardOk boys and girls, here is one I have not seen in my 50+ years of playing around with the Model A. It is a 2 piece crank pulley, but as you can see, it is not like the normal 2 piece. The pic on the left is the back of the pulley and the 4 indexing nibs for lack of a better word. The pic on the right is the end of the crank with a collar around the actual crank and the 4 indexing detentes.

by plyforAttached are photos of the 2 piece pulley offerings from the vendors. Some research indicates that the 2 piece screw type may have weak metal at the spokes which perhaps can be seen in the photo.I have the slotted type that fits together very snugly , polished the inner part to a mirror finish and don't want to buy another if there is some consensus which type may be preferred. Sorry to revisit this...

by Jim CtenThanks to all that replied to my question about the dist shaft problem. My father had some spare dist. so I fixed the lower shaft problem and changed the dist. Nice and tight. New problem the crank pulley moves back and forth about an 1/4 to 1/2 turn. I believe it is a single piece pulley. Question #1 Would that much movement just be a bad pulley or can the crank be bad? Question #2 does the pan have...

by fmr187After cleaning up my one piece crank pulley I noticed a small crack that runs from the outer edged in to where the fan belt will sit, on the outer side of the pulley. Is this a major issue and a problem down the road if I reuse it?

by WascatorHi, I am new to Model A ownership; I have a 1931 chassis with engine that runs perfectly; however I noticed the crank pulley will move 45 or so degrees back and forth. I think perhaps a key has failed or what? Any advice before I remove the radiator and take it apart?
