Pressing Piston Wrist Pins

We didn't heat em at all, a Lil oil... not reusing the stock pistons. Ever. They're smelted by now probably.... was a prepped block. Rats got into the building, ate the bag, and built a nest in the lifter valley.... was hot tanked, w/ a new 030 bore, new cam bearings...a Lil wire brush in the lifter bores cleaned em up really good, may have to get a silicone dingle hone. definitely need to CLEAN THE HECK outta the rest of it. I'm kinda pissed about it. That what happens when you let em sit for 15 years.

I cannot tell you how may pistons I've pressed cold and never broken one. But, I had an entire pin bushing set at my disposal. You can do it cold, you just have to go slow and easy.

It's done now, maybe I should inspect the pins? Have 7 old Trw 11.5 /1 forged slugs... had 8, one looks corrosion kissed. Called them, been Years , it was only 54 bucks for 1...heads came off a running 413 we shoved In a Dart. But not originally 413 heads. There 452s

I don't think I'd sweat it.

Much Appreciated Rob! Is a wire wheel on a grinder Pysco to get the filth outta the valley? Ideas? HELP! ??

Valley?

Oh the intake valley? Naw, that'll work. Just make sure you blow it off good. Might even pressure wash it. Course you'll wanna oil it down after. I recommend Fluid Film.

Lifter valley, where the rats were making babies. It's surface rusted,, that's some corrosive piss...

Man I wish you were local. You could just bring it to me and I could do all that. Clean it up, hone it, put cam bearings and freeze plugs in. Alas, you're not.

I know, that sucks. ..I'd love to come and do some Carpenter stuff there... I'm pretty sure by the time I properly clean that, the new (15 year old) cam bearings gotta go....

I guess to be clearer would be if I asked just what it is that a machine shop is doing that cannot be done at home?
I do machine work at home, I have lathes and a Bridgeport, there's no magic done in machine shops, it's simply careful and precision work.
The UTG vid does mention a forge for heating up the small end of the rod, but as he displays, that's nothing really special.
Thanks for the input everyone!

That's often the logic people have that dont have any practical experience as a trained and qualified machinist. There are many people that buy micrometers and calipers from Harbor Freight that have never seen one before and think that just because they bought them, they are qualified to use them. There are many secrets and tricks of the trade that are learned from working in a "real world" environments like engine machine shops. I worked in a top shelf race engine shop for over 15 years. Our customer base was numerous NHRA record holders and drag racing champs who's names would be recognized across the country. So dont underestimate what skillset is held by those that have experience in those fields by over estimating your abilities because you happen to own a mill and lathe. I own those also and have a CNC mill at my home shop also....
Now, I'm not saying you haven't picked up certain skills and knowledge by doing things that you do, but there is a lot that people dont know because certain techniques, skills and knowledge are only gained by working in specialty industries. And even some engine shops have bad practices that may not be considered as acceptable compared to better shops. A lot of our weekly business was spent fixing and redoing other shops bad works....

Oh for fucks sake dude get over yourself. Secrets and magic. Harbor freight.
You're just a punk *** kid trying to sound smart behind a keyboard. You failed.

That response is uncalled for. You asked for an opinion, and now you don't like it. I have pressed pins, my self, at home. Sometimes with sucess, other times not so much. With the proper tools/equipment (pin guides) the chances for success increase.
EDIT: I don't have the proper tools for this

I doubt that....but as Charlie said, it's a crap shoot. If you want to give it a try go ahead. It's your time, money and parts....
 
Oh, there's blood on everyone's hands. First for one coming across with an elitist attitude that if you haven't been doing this for 50 years you don't know squat and then for another overreacting to that attitude. I have the Chrysler special tool and have pulled and installed many a pin with no problems. There is no magic to doing this if you have the tools to do it.
 
I put some old six pack pistons on some LY rods at home one time. I used a propane weed burner on the rods, had a jig of sorts set up so the pin would go in the correct distance. Worked good.
