Do it the right way, get the small ends of the rods bushed for "full floating" pins. Be sure to have your pin bosses drilled for oil access if they are not already.

@SPUNKKK I don't know how to explain this... your theory would work if it was a gas. In the metal, for the hole to "close up" the metal atoms would have to move *closer together* to constrict the hole. What they want to do, however, is get away from each other so the whole disk expands, including the size of the hole, to make more space for everyone (every atom). It is a hard concept to understand without knowledge of the atomic theory.

So many morons posting in here T_T

@SPUNKKK that's a good question
-
hey..does this account for every ENGINE??when installing pisstons on rods..FOR example..a integra gsr
-
@SPUNKKK U must tell loud which way to expand
-
If heating makes the metal expand, shouldn't the hole get smaller? How does the metal know which way to expand? :)
-
I notice that you appear to be heating the small ends until they go blue. Won't this destroy any heat treatment the rods have had?

@caddy52 and thats why you are just a shade-tree mechanic after 30 years. most people dont care about how many you can do vs quality. I would rather have it done absolutely right like this, than to have some backyard mechanic do it 3 minutes quicker and it be 50/50... i mean come on...
So you don't have to worrie about which way the rod goes on but more on how the whole piston is installed. Rods can't be backwards or upside down or but can be reversed as long as it's installed with arrow to front. You confuse the hell out of folks when you said it matters when it dont

@jungledrum123 you need to be aware that there are many types of rods that have oiling squirt holes in them. These kinds of rods absolutely must be hung on the piston correctly, or the oil will squirt away from the cylinder wall and cause damage. Also, any experienced engine builder will stamp the outer side of the rod and cap before dis-assembly with numbers or dots. This is a procedure that helps all through the machining and re-assembly processes. The method used here is standard practice...

Why can't you just press the pistons pin back in?

@japajill
If you watch again, at :53 the correct size pinston pin is attempted to push in by hand, showing that the connecting rod small-end is slightly smaller than the piston pin.
If you forcefully pressed the pin through the rod end at room temperature, you'd shear off the inner bore of the small end of the rod with the hardened steel piston pin. It just won't work that way without damaging the connecting rod.
The only install method for "semi-floating" pins is what you see in this video

realy nice! But how can i remove the pistons from con rods?

If you mean how can you remove the pistons from forced fit connecting rods at home...you really can't without a hydraulic press.
If you tried heating the end of the rod with a torch, you would also be heating the wrist pin of the piston and it would expand along with the connecting rod end. You wouldn't be able to remove the pin from the forced fit, even when heated.
This is why we made a machine shop section of the DVD, to show you all the stuff that you will likely need to have a shop do...
