front axle collapsed! ford 2n

I have been pulling a trailer around for a few years using a ball mounted to the point on the front of the radiator grill protector. Yesterday it appears that the load became to much and the pin which supports the front axle sheared. The axle flew up until the generator blocked it and the fan went through the radiator. Not good! My question is before I get to it and take the hood off etc., is this repairable?? I didn't pay attention to that area before so am not sure if that pin has sheared from an unreachable / unweldable point inside the engine block or do I just need a new pin. Presume it was attached to something. Any advice appreciated!!


In the photos I have jacked up the engine block and put the pin back through the axle hole

The pin does not go into the engine block. Aside from the collateral damage your concern would be damage to the bore in the axle support. A new pin and if needed a good used axle support will make it whole again. That is the 8N style support used on the late 2N's and all 8N's.

pin wasn't in your engine block!

it's thru a hole int he axle and front bolster.

might have had a loader pump drveshaft on the ssnout maybee att one time though..
 
Axle looks to be in good shape, so if take the hood , radiator off I should be able to slide a new pin in ? but then how is it held in place? I cant see how the existing one was attached , presuming somewhere around where it has sheared..
thanks for the help.
 
i'd check the pin bores to see if you need a repair bushing

and there will be a keep er, design slightly different depending on what bolster you have.

Those pins are quite substantial and not likely to shear. More likely it worked out of the bore in the axle support and collapsed under the load. The pin (p/n 3126) has a teardrop shaped flange welded to the front end and is held in place with a bolt installed through the flange and into the front of the support (p/n 3029). Check the bores in teh support for damage. The new pin should be a good snug slip fit in the support.

is that a beat out bushing we are seeing int he bolster? hard to tell on the phone? looks paper thin..
 

Can you take a pict or two from the front end of the tractor where the pin mounts.
Below is a picture of the teardrop front flange of the pin that The Old Hokie is referencing.

It was my from my original pin. When I bought the tractor, it had a loader attached for most of its life. At sometime in the past, the pin broke off from front flange. The axle never dropped because the flange was bolted to the front of the bolster and didn't allow the pin to slide out. Due to the loader, the pin was worn paper thin at the top.

Can't really get a pic of the teardrop as still to get the hood off but it exactly like the one you pictured , from what I can see the pin has detached / sheared from the teardrop end as I can move it back and forth through the axle / bolster exactly as you are describing . Not quite sure why the inner end of my pin which you can see in my first post pic is so trashed . On the front of my tractor is an added on radiator grill guard bolted to the axles which may indicate the use of a loader ??

Ive never seen that front bumper used with a loader. That's an ad on to protect the grill/radiator. Id be more concerned with why the extra washers and nut on the flange. Its probably why you had this problem. If the pin was worn that thin to shear like that I cant believe it was neglected that long. Generally the center of the pin wears on where it rides on the bushing.

Somebody has been farmerizing that pin. Looks like they put a washer under the bolt to keep the pin from coming out the front and it went the other way.

I can't even begin to even think as to what the purpose of that combination of washers and nut is supposed to do other than he only had one bolt which was too long and needed to shimmy it up.

The picture that shows the king pin flared out and serrated I think is not a pin but maybe a spacer bushing (3024) that may have been installed in the wrong place. I cant see how the pin was perfectly worn down internally around the entire circumference other than having a pump shaft rotating internally that was not originally installed correctly.

The inside of that worn piece is very shiny so I don't think it is the axle bushing (3039) which I believe was bronze.
 
Finally got her apart . Think it's exactly as you were saying . The pin obviously seperated along time ago from the teardrop . Pressure kept it in there . At some point the engine block side of the the pin started rubbing on the pto point and wore it thin and out . My bolster pin hole has been worn somewhat oval . The axle hole is good. The bushing is firmly stuck in place in the axle . Will order a pin and see if it works . Appreciate all the advice . Thanks !

The end of that pin rubbing against the crown head bolt had to be making quite a racket!!! When machinery talks to you it is always good to listen......

I agree with what TOH, has told you, and would like to add, that if you do not fully inspect for cracks and wear on the bolster, and axle bores....plus installing a new bushing...and replacing the crown head bolt, You may be into taking that whole thing apart for repairs, way sooner than you think.!!!

My 2N was similar to yours, in that area, when I first bought it,
and it cost right at $200, to repair/replace all of the damages.

You are this far in taking it apart.....why not finish the job correctly, and not have to worry about it at a critical time, down the road!!????

My 2N, when I took it apart, for repair, 6yrs. ago!!! good tight steering and service since then!!!



Good luck to ya!!
