1940 Ford front I-beam axle
I acquired a NOS 1940 Ford I-beam axle. Before I install into the wishbone, is there a front or back to the axle?
The kingpin lock bolts fit front or back exactly the same. |

My understanding is that there is no back or front side.

Re: 1940 Ford front I-beam axle
Even though there are a few hold-outs that refuse to believe this (because they find difficulty installing the king pin LOCKING PINS), as Mart and rich b said above...there is NO front or rear side. The axles are symmetrical! DD

Re: 1940 Ford front I-beam axle
I suggest there is a front and rear .any stamping information or embossed lettering that is found on the boss of the axle close to the one end ,the axle should be placed with the embossed lettering to the right front.

Re: 1940 Ford front I-beam axle
Actually, there is a front and back. Once you get the axle installed, get down low, directly in front of the car and look at the axle. The side you can see from that angle is the front.

Re: 1940 Ford front I-beam axle
johnny.......Could you possibly post a picture of said stamping or embossing on a '37-'41 Ford axle? I'm specifically NOT referring to a "heavy" 1932 axle. DD

Re: 1940 Ford front I-beam axle
This has been debated before. There is no "FRONT". Both sides are the same.

Re: 1940 Ford front I-beam axle
I agree.all that there is no difference with a new axle ,however from factory I suggest that the axle was installed with the Ford stamp and part #,facing the front [right side] Where one should be careful is when restoring a car,taking the front end apart: one could install the axle reversed as it is quite likely that some time in the cars life an attempt was made to bend the axle ends to correct an alignment problem putting it in reversed would create a bad steering condition.

Re: 1940 Ford front I-beam axle
Bit like the old story about how to tell the back of a tree from the front.
Look where someone's taken a dump. That's the back. |

Re: 1940 Ford front I-beam axle
Difficulty in fitting the kingpin cotter pins in is probably real. It happened to me. I rebuilt the front end on my 41 pickup and reversed the axle when putting it back together. One cotter pin went in slightly tight, but hammered home nicely. the other did not want to go in. I ran a 9/16" drill through the hole to remove any burrs or corrosion etc. and the pin went in fine. I should have done that first on the first hole.
So saying the cotters don't want to go in if it is the "wrong" way round is probably true, but it is only because the pins were previously in the other way around and have raised a burr or some other slight imperfection. Mart. |

Re: 1940 Ford front I-beam axle
Guess it must be. When I was a kid the similar setup holding the pedal cranks on our bikes was called a cotter pin.

Re: 1940 Ford front I-beam axle
Thanks Mart, it is interesting the different terms that are used in different areas for automotive parts and tools. This is what I have always referred to as a cotter pin.

Re: 1940 Ford front I-beam axle
Yep, looks like a common British term.

Re: 1940 Ford front I-beam axle
As I remember the king pin locking pin on my '41 is a tapered pin that is installed from the front and the stop nut to the back that also serves as a stop when turning. If the axle were to be installed reversed, the pin would be installed into the king pins the wrong way.

Re: 1940 Ford front I-beam axle
Let's put it this way- the axle doesn't know right from left, if you do happen to spin the axle and get the right side on the left it will not matter. The hole in the axle for the cotter is a through hole, it has no taper. As has been said here already if there should be some deformation to the edge of the hole from the lock washer and steering stop you may need to run a drill or even a rat tail file and dress the hole a slight bit. The only taper is not in the hole, it is on the cotter, the cotter is the same diameter it's whole length, with a 3* taper wedge machined on it to lock the k/p as the steering stop nut is tightened.
Made the way the cotter is means the machining tolerances can be a bit "looser". Think about it, if the cotter was tapered to fit the hole then the taper that holds the king pin would have to be spot on to do it's job.
