Does anyone have any pictures of the V8 60 axle king pin lock bolts. Apparently they are different than the standard Ford king pin lock bolt? Who supplies or has them?

Any help would be appreciated
 
Here ya go....definitely different than the ones for the I-beams. Don't have a clue where you could find any. DD

They are different if your 60HP car was equipped with a tube axle. The photo that Coopman was nice enough to include are the pins required for the tube axle. And yes, they are SCARCE.
All "I-Beam" axles, whether in a 60, 85 or 95 HP equipped car, used the same bolts.

Kube makes a couple of important points......The lock pins pictured are used ONLY on what is generally referred to (but not necessarily CORRECTLY) as a "V8-60HP Tube Axle". Two points to be noted...the "tube axles" WERE NOT installed in ALL V8-60 HP equipped cars.

Secondly, SOME 85 and 95 HP cars (1937-1940) WERE equipped with the tubular axles.

To be clear.....the lock pins pictured above were only used on the TUBULAR axles......not the I-beam axles. DD
 
Can you show the other side of those lock pins? I'd like to know if they had a groove in the side of the shaft like a normal lock pin. If not, what presses against the kingpin tightly?

If there is no groove, and they are just straight shafts, I'd think a resourceful machinist could replicate something from a pair of bolts. Maybe just need to weld a knob onto the heads?
 
Just being curious; did the original tube axle kingpins have a half round notch like the early "A"s or the slot like I-beam kingpins.


My tube axle has 9/16" holes and was used with regular lock pins, sure it was modified sometime in the past.

alchemy ...... These pins are a round cross section.....NO grooves like the I-beam pins. The shank diameter is 0.463", or about 15/32".....kind of an oddball bolt size. I took four nice pictures this morning and tried to upload 'em here. They were too big, and I can't re-size 'em. Send me a PM with your e-mail if you can upload them here.......I'll send 'em your way.

Rich B ..........The slot in the king pins is the regular old three-sided notch. The round section of the pin interferes perfectly with that notch to hold it snugly. Yes, the pins could be home-brewed by the right guy.

I'll post all of the dimensions if anyone wants them. DD

OK guys, here are the dimensions. If there are any others I've neglected to note, let me know.

Overall length: 3.212"
Total shank length below hex (including threads): 2.063"
Total thread length (threads ONLY): 0.651"
Shank diameter (NOT tapered): 0.463"
Stub length (exposed knob-like part above hex): 0.933"
Stub diameter (tapers down FROM hex): 0.548" MAJOR to 0.538" MINOR (not visually noticeable)
Width (thickness) of hex surfaces: 5/32"-major // 1/8"-minor
Hex size (actual): 0.682".....for 11/16" wrench
Thread diameter (actual): 0.433"......(7/16-20 thread)
Transition radius from STUB to hex: Approx. 1/4" radius

One other note.....these pins insert from the REAR side of axle, where-as the I-beam pins insert from the front. That's because the STUB is built-in to these pins, where-as the stub surface for the I-beam pins is actually the acorn-shaped nut that threads onto those pins.
 
These are easily made on a home lathe but it would be wise to make them from SAE4140 rather than mild steel or screw stock (Ledloy). These act as spindle stops and some people are heavy handed on the steering wheel.
 
Interesting. So basically the lock bolts will lock the kingpin from spinning, but not push it sideways to prevent "rocking". I wonder why Ford went with this method in this application? The regular wedge pin method seems superior to me.

Thanks for all those dimensions, as it will make it easy for all us tube axle owners to replicate our missing lock bolts.
 
I've been wanting to get one so I could have my machine shop guy replicate a bunch of them. Anyone care to be a donor? I'll get the original back to you and a new set.

V8COOPMAN supplied all of the dimensions. Any half way decent machinist can work from that. You really do not need a "sample".

Well! IF my tube axles were bored to use the 'wedge' type keepers, it would explain why Sid has seen them both ways, and why mine are bored 'large'.

They are made out of "UNOBTAINIUM"....more rare than chicken teeth. You can have a machinest make you a pair from the dimensions I supplied above in Post #9, referencing my pics in post #10. One last idea...PM FordBarn member "barnfind08". He carries some really obscure and hard to find NOS parts.


Those things measure something near 15/32" diameter. Yup, a really oddball size, but with a little creativity, you could relatively easily fashion something useable by turning down a couple of pieces on a lathe. DD
