I need to replace the wrist pin bushings on my original iron pistons. I need to do just one until I do the complete rebuild. I am hoping someone can give me the best method. I do have a press and the ability to ream these to size. I just want to remove the old ones install the new ones without destroying the piston.
Pete - I'm pretty sure that you're gonna' get a lot of advice here to go to aluminum pistons.
The long term plan I have is for a total rebuild and that's the likely path. I need to get by just for the rest of this driving season. So I want to be able to drive this just a bit more this season, but I am concerned about the noise...
Best practice is to use/make a fixture to hold the piston - as in a cradle support. A wooden one will suffice. Not too difficult of a project.
Thanks Steve, I didn't think it should be too hard of a thing to do... I get the car apart next week and find out what I need to order along with my current wish list of stuff.
Pete, with just one piston to do,I would be using a length of all thread and nuts to wind the bushings in, one at a time, form each side of the piston. That way there is no risk of deforming the piston.
Hope this helps.

Pete, what I did to get the old ones out is cut them with a hacksaw blade.In thirds.
Alan and Jim Thanks for your suggestions, I am glad there is this many folks out there who want to keep these cars going. I have had it for over 20 years and I plan to do a complete rebuild in the winter.
Thanks again, Pete
It might be simpler to replace the piston. Most folks will give away their old iron pistons when they rebuild their engine.
That's a good thought. I guess I need to ask some locals and if I get no where I just do the job..
Here a few photo of what I first used to replace the bushing. A 16mm key a long bar that fits the key and a hard wooden block with a hole the bush fits just in. You will need a good hammer or press.
Than I made a small tool with the photos I get from my friend Toon Boer from the Netherlands.
Both work great.
To set the new bushing just use a long bolt nut and washers
An excellent idea! I also think that the fabricated tool could be used to remove and replace the busing! Just change the stacking and use a longer threaded bolt or threaded rod...
The bushing need to be honed to size, I doubt that reaming will do the best job.
