Replacing king pins

[30blindback]

Need advice on replacing the kingpins. Take the axle off or leave it on the car. The brakes are currently off so I think the axle should come down without much more work. Any pitfalls to avoid and advice on the proper techniques needed.

Most often all that needs to be removed is the pin lock, pins, and the spindles.

No need to remove the axle!!!

UNLESS it is like mine with axle King Pin holes elongated or egg shaped then the axle will need repair. Does your user name indicate type of Model A you possess?

Leave the front axle on the car. Take the spindles off so you can replace and ream the bushings on a work bench. Be sure to chock the wheels and support the car with stands.

Thanks for the advice. Axle will stay on the car.

Without side tracking the thread , too much... what is the diameter of a Model A king pin? I ask because I have what appears to be a piloted reamer that would be used for such as a king pin bushing.

Thanks,

It might be best to measure the pins you intend to install.

Thanks "bb" for the info. The pilot reamer that I have must be for some other application, found it along with a bunch of other tools.

Do you belong to a local Model A club? You'll find a world of hands-on help there. When I did mine I took the spindles, new bushings, and new king pins to an old time machine shop. He pressed in the new bushings and honed them to perfect fit. If you go that route, check with others in the club to get a recommendation for a machine shop that knows what they're doing.

Here is info on a Club in the Portland area, I think that's about 30 miles or so from you.
You might consider giving them a call. Unbelieveable knowledge, lots of cars, tools, tours and best of all great friends

What size is your reamer? The early Lincolns used a 15/16", or 0.937 dia. kingpin. DD
