I come up with MOOG 8294B however the keeper bolt across the spindles through the flat of the pin looks different in the picture here: http://www.aftermarketsuspensionparts.com/moog-8294bAny comments? Do these look OK? Thanks - Joe
1947 - 3800 dually known as "Deadwrench"Link to a few photosIn this world there are givers and takers.

Joined: May 2005 Posts: 8,877 | The picture looks appropriate, if the part number traces back to your application I'd say they're right.
In general when shopping for kingpins I search for ones with the bronze bushings instead of plastic and thrust bearings instead of washers.
Usually more than one possible kit or part number exist for each application. | | | | | Joined: Jan 2015 Posts: 208 Shop Shark | | Shop Shark Joined: Jan 2015 Posts: 208 | Rockauto- ACDELCO 45F0013 is what I used on my 49 3800. I had to take them to the machine shop to have the bushing honed to fit.

Joined: May 2005 Posts: 8,877 | Reaming or honing the bushings to fit the pin is part of the process. If you didn't need to ream them that would be cause for concern. | | | | | Joined: Nov 2012 Posts: 431 Stovebolt Photo Moderator | | Stovebolt Photo Moderator Joined: Nov 2012 Posts: 431 | The goods have been ordered. I'll keep you all posted on the installation. Grigg - if the replacement bushing is snug in the spindle, and sized for the companion pin is honing still required ? - Joe

They are installed in the spindle and reamed or honed inline with each other and to fit the pin. Standard practice for kingpins.

I had mine pressed in by a heavy duty truck service center. This way they took care of everything that was needed for a correct fit. | | | | | Joined: May 2005 Posts: 8,877 . | | .

A 1 ton is a 3800 | | | | | Joined: May 2005 Posts: 8,877 . | | . Joined: May 2005 Posts: 8,877 | Were not talking about 1/2 tons here in the Tons o' Fun. They are different and have unique king pin/floating bushing situation not found on most any other vehicles with king pins.
3/4 ton and up are pressed in bushings and reamed to fit, common practice. | | |
