Swapping Pressed Pistons For The Home Engine Builder

When a machine shop with a proper rod oven isn't available or your budget is super tight, a piston/rod swap with pressed pins can be accomplished using a mapp gas torch and following the simple guidelines.

I can absolutely attest to this. I couldn't afford machine shop stuff when I was younger. Had to build and learn and integrate from others. That led me to working at a machine shop and expanding. I'm now a custom engine builder, self employed, and have more work than I want. You younger people have now idea how easy you have to people like UT a keyboard away.

Hey Uncle Tony .. great video man ! . My Father was a mechanic his entire life ,. and worked on everything in his mechanic shops , including doing his own machining with his own equipment . when he would assemble pistons and rods he would basically do what you just did in your video . except he would usually use his oxygen and acetylene torch , with a small rosebud tip on it . because like you said , most piston pins have an offset to one side , he had spacer tools that he made from copper for the spacing . they were U shaped tool with about a four inch handle on them . he four of them in different sizes , but the one most often used was the .060" thick one . and he would also use 30 weight motor oil on the piston and pin during assembly . but you are absolutely right , it is all the same concept . thank you for the videos Tony Tim from Wisconsin .

Brilliant, you have cleared a niggling worry I had after I received my pistons and rods back from the machine shop. I noticed the wrist pins were not all precisely central when the connecting rod wrre. I enquired with them about this and they said it’s fine. Being my first warm V8 rebuild, I was skeptic all but you have cleared the worry. Good job, thanks.

[@sometimesleela5947]

when I got mine back (f302), the pin ends of the rod were all discolored dark purple. it's been nagging me ever since that they might have killed the forge strength by overheating.

[@ohm1945]

@ SometimesLeela Actually, so did I. But I figured with heat there was always going to be discolouration but to what extent. Mine too had dull purple shade but our man Tony has lifted our concerns.

[@rustybritches6747]

that would piss me off especially with how much some of us are paying for the simplest of stuff done app machine shops! in this situation I would expect that pins to be centered within .020" at the most and if they weren't then I would have them do it again which would cause me even more concern because of how many times the rod had to be heated! parts are not cheap and I have a lot of bad experiences at machine shops and their prices are definitely not cheap!

[@rustybritches6747]

the prices I'm paying at my machine shops I demand perfection especially for the price of quality parts, so those pins better be pretty damn close to dead center on all eight!

My Dad has done this stuff since the 60's and said, "Everything you are Saying Word for Word", on a Friday Night as he showed me how to do this very same thing. I learned 2 things, the right way to do it, and how to do it when you can't do it the right way, but it has to be done anyway. Great Video UTG! and an even better message.

[@Face2theScr33n]

Man, I just pulled and pressed a carrier bearing on my 86 Volvo driveshaft. The manager at the part store was impressed, said he bought a new shaft because of the way his was pressed together. Not sure his vehicle, but I was like "really? I'm not even that much of a gearhead and I'm doing it!" No fire needed, just cut a 1-3/4" notch in a block of wood and gently hammered it on. Pain in the ass is it's special order shit, and I got the wrong rubber donut it goes in so I'm waiting a week for the fucker I need. Glad it's a project car and not my daily (it will be again sometime). Not but a few months ago I was watching Tony talk about people that are doers. I was not in that category then, but I'm working on being more of a doer! My primary truck had a few problems I needed to fix. (Body control module had a burnt circuit- started the adventure). When I was satisfied (and bored), I dragged the old Volvo up out of the dirt. Thanks for the inspiration, Tony! Edit: anyone wondering, parts have been pretty cheap so far, but nobody has them in stock for same day pickup. O'Reilly has become the standout in my recent experience, if that helps anyone. Used to go to Napa a lot but they close earlier/less convenient for a non-pro like me.

[@craighansen7594]

Using a factory installed piston as a guide, make a simple fixture to help you get that pin centered. It really helps when you have that hot connecting rod and you are trying to move fast before it cools.

[@synopticfixes6213]

Of course a machine shop is easiest but I have done it at home without much trouble. Its all about setup. I used a block of wood with a section cut out with the same radius as the piston. I used a cheap tabletop hydraulic press from harbor freight. Heating the rod in the oven and cooling the pin in the freezer reduces the amount of force the press has to apply.

I've used the same method installing bearings. Put the bearings in the freezer, then heat up the pocket the bearing sits in. When it's warm, pull bearing out of the freezer and should slide right in. Can also use an oven for heating parts too, if their small enough. Great video! This is the garage mechanics way taught to me by my grandfather.

Have put new bearing races in many truck hubs this way, also ring gears on flywheels.

[@graysona1800]

I was half expecting the party trick with this one... in my automotive class, our teacher did this exact thing (with an oxy torch instead, though) but when he let it cool down, he showed the transfer of heat from the conrod to the pin, and from the pin to the piston. My teacher did this by holding the connecting rod up off the piston by a bit (about a 45 degree angle) and when the con rod cooled down and the pin heated up, the pin locked up inside the conrod and the piston, making the conrod stay on the 45ish angle... until it dropped when the piston soaked up some of the heat from the pin, expanding the hole to be bigger. Great content nonetheless, and was everything I remember being taught about this! I even distinctly remember the feeling of the pin slipping into the conrod... good times!

[@natevanlandingham1945]

It's amazing what heat and cold will do for press fits. I had an interference fit bearing in a tractor axle where the old one slipped out and I couldn't get the new one in and due to it being inside the housing I couldn't tap it really with anything. Bearing sat in the freezer overnight and I heated the housing just a bit with a propane torch and when I got the bearing out it just pushed right in with ease.

[@johndunn678]

I grab the rod through the big end and hold it in such a way that when I extend my hand the tang will be in the direction I need it in and keep it like that. That way once the heat is off I can quickly assemble

[@pauberrymon5892]

Reminds me of heating up a starter ring gear until it falls into a new flywheel, a new M Benz standard shift flywheel doesn't always come with a starter ring gear, so sometimes you have to patiently tap around the old flywheel with a brass drift to remove the ring without breaking it and put it on the new flywheel. If all goes well getting it off, just lay it flat and heat the crap out of it with Acetylene/Ox torch. But never ever tap the ring while it's hot. It will snap like popcorn. Great Video Uncle Tony.

Thanks Uncle Tony your the best! I asked this a couple weeks back on a live stream, great to see a follow up video as I know it’s a hot topic with not a lot of info out there. I ended up building an adjustable jig that clamps the piston and sets the wrist pin depth, very similair to what a machine shop has. Ive always been told if the rod gets dull red/red hot the rod is toasted and might aswell throw it out. I did this last week in my SBC I only heated the rods until they were blue and the wrist pin slid right in no problem, Great work by the way appreciate the video!

[@ar501dboy3]

I "press fitted" my whole Speed Pro hypereutectic set with nothing but that exact bernzomatic propane torch. I had to, because everywhere I tried to take em literally told me "I can't guarantee that I won't crush these pistons with the press". Freezing the wrist pins made it sooo much worse. It cooled the rod too fast and then you don't have the same window of opportunity to get it centered. I just heated the rod and pushed the pin through exactly the same way you demonstrated, to where my fingers stopped it.

[@SOLDOZER]

Pressing he piston out with a press ruins the piston as the shop told you. You need specialty jig. The shop was explaining that to you but you did not listen.

@@SOLDOZER It works without damaging anything if you're only moderately careful. The socket is Cr-V, which is far softer than a pin, so it won't be damaged that way.

Sure looks easy. I'd like to see how to remove the pin and rod by this method - or any method. Hyd. press without a jig is a rough go. Heating the rod end just seems to heat the pin too and nothing moves. I've tried this many times and the only way I've ever got them apart is with a cold chisel and hammer. Crack the rod and drive the pin out. Save the piston, scrap the rod. Usually needs to be the other way around.

[@samohtnotslar]

Very good videos Tony, I enjoy your information

[@joeanspach539]

Great video, however, I see one small issue, which on factory engines, may but be an issue. This method heats the rod to beyond its "critical point" or the area in which steel loses any temper it has, which is at about a dull red. Another way to check this is if it loses its magnetism. Steel, heated to that point, quits being magnetic. So if the temp gets above that, any temper is lost. If this affects stock rods, or if temper matters in this context I don't know, but it's something to take into account.

[@SOLDOZER]

It does matter, and he heated it way too hot. You only want it to get in the 400 degree range. Red of any shade is above 900.

Excellent vid Uncle Tony. I'm assuming this is one way to do the much debated practice of "turning the pistons around backwards" on a 318,to change the offset that you mention in the pistons,to get a bit of added low end torque. I ask because i've always wanted to try it.

Before too long I'll be doing this . I have to take the factory rods and pistions apart for my 360 build . I'm going to buy a nice large kitchen digital scale build my own pistion tree to hang each end of the pistion off to weigh both ends of the rods and the new pistion to balance the rotating assembly
