'48 F-1 king pin time

[1948F-1Pickup]

I'm going to hone for fit. Are the bushings that are commonly available at the store (MAC's, etc) ok to use or should I source bronze material and do all the machining myself? The reason I ask is I think I saw a picture of the bushings they sell and it was a split design and not a solid piece of material.

Buy a complete kit and have them fitted. They are split bushings

The base steel backers are rolled from sheet and locked into a circular shape. The split is not an issue IMO, many people have honed them. Dennis Carpenter's in mine, 10+ years and 15k miles with no issues. If you were to make your own, you'd have to figure out how to make the grease distribution grooves.

The ones I bought were not spilt and had lot of meat. I had adj reamer few times then used a finish reamer. The king pin has like a washer on top .knock that off and pound down if you are having trouble pushing out from bottom.

Don't try to fit new homemade bushings to used steel pins

Do you recall where you purchased them?
Not really wanting to machine bronze stock if I can avoid it.
(The pins themselves I'll replace with new ones)

Machined all the front leaf spring setup in bronze from McMaster-Carr.
It's super accurate but was a massively tedious job.

I think mine were from Macs, there is a lot to remove with hone you need a reamer first.

Even if they were a locked one piece they need to be installed to be honed / reamed to size

....an in align with one another.

Rockauto have a variety of kits available, some of which include the correct shaped nuts. they also have oversize pins available if your axle is wallowed out.

Mart.

Mart-


Took it apart today. The drivers side I've already scrutinized and looks like I'll need oversize pins.
Thanks for posting that info....... didn't know those were even available.

Nor me.

I don,t know how you could wear the king pin. Take the new pin and see how loose it fits in axle. There is the old idea the small pin is not needed to keep the pin from turning. If that is the case have a shop do the job and remove the axle.

Thanks for all the advice.
King pin hole in the left side "axle" (I-beam) was
wallowed out some. I just got done honing that
hole out for an oversize diameter king pin. (Moog 8440B)
That was a really FUN job..... hoping the right side isn't
jacked up as well.

Anyhow, attached to the left side spindle is this item (see
photo). It was held in place with a huge slotted nut, fastened
with a cotter key and torqued like it's holding the Brooklyn
bridge together.
The Ford parts book calls this an "arm" (spindle). 7RC-3134
The hardened ball at the end looks like it has maybe 1% wear....
I'm tempted to reuse it as the overall diameter looks pretty
consistent and it appears to be swaged to the arm.

My question is- I'm sure this arm is ok to reuse in the condition
mine is in and I'm guessing to reuse it is the norm unless it has
measurable wear?

Thanks.

If the ball is still round within 1%, as described, there is no reason not to reuse it.

Did you measure the ball at incrementally at several positions?

[1948F-1Pickup]

I looked at it pretty closely with a vernier caliper. I'd have to take
a micrometer to it to be more precise. I don't think it's necessary.

Driver's side reassembled..... no play in the king pin/spindle now.
On to the passenger side.
