Connecting Rods Machine Shop Video-Engine Building DVD

[wendlormsby]

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.

So many morons posting in here T_T

hey..does this account for every ENGINE??when installing pisstons on rods..FOR example..a integra gsr

[SPUNKKK]

If heating makes the metal expand, shouldn't the hole get smaller? How does the metal know which way to expand? :)

[atakobcych3]

@SPUNKKK U must tell loud which way to expand

[jablooglius]

@SPUNKKK that's a good question

[117nathanmyers]

@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.

[jdudb]

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]

I have been building Engines for almost 30 yrs and have never used a rod heater,i can mount 3 sets of sm block chevys,vrs 1 set with the rod heater with a torch,any way thats how I was taught,and it works just the same.

[Runkleforskin]

@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...

[muszyngr]

excellent video, I had no idea how they put the pin in the piston and the rod, now I do, but did you show us how to remove them, or did I miss that part, please don't skip steps, you have a good thing going here, and buying all new replacement parts is a cop out, so many old parts can easily be saved with some elbow grease

[koopooda]

What would happend if you used connecting rods and pistons from another motor? would it be better to replace the piston and even so would I use the foreign connecting rod?

[Xx1kro5xX]

I own a Suzuki Grand Vitara 2002, Which high quality engine kit do you recommend me guys?

[celtic5yamum]

that just made it look easy... as much as id like to play with a car engine, i think ill stick to trying to get my lawnmower work :P awesome video!!!

[Lokivoid]

Drop the pistons in a Ultrastonic bath, DO NOT blast them or hand sand them unless the ultrasonic cleaning process failed to remove the deposits.

[ToniFilth]

@BoxWrench how do you get the rods out from the pistons,the old pistons,do you heat them while they are on the pistons or?

because i can't find a video for it.

[revolution3nz]

Hi there Ive got JE pistons and eagle rods for a 4g63t engine vr4 6bolt my piston pins just pass right through them? Im in New Zealand also and am definately going to ordera few dvds from you, It shows through the dvd that the presenter truly knows what hes talking about not like other engine building dvds ive seen cheers Matt Nz

[jungledrum123]

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

[BoxWrench]

@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...

[Txbritt455]

@jungledrum123

That is not correct for every engine. Pontiac rod's are chamfered on the big end on one side only, that side faces the crank and matches the chamfer cut into the rod journal. Flipping them around would eat the sides out of the rod journal.

[jungledrum123]

@jungledrum123

Those arrows needs to face to the front when the rod goes on. It doesnt matter where the squirt goes cause it will go inside the cly wall regurdless as long as the arrow is to the front. As far as the rod itself goes it just needs to go on the pin before it cools down. You can turn it which ever way it needs when you install it. Its just that simple and the video said its not a simple procedure. ASE teachbook tells to mark it but an expert already knows and never does.

[indyboom]

@jungledrum123 yes it does,. try a chevy hero.. tangs always face out

[youdragon]

how much does it cost to pulll a engine and replace the rod bearings? on a 1997 gmc sierra 5.7 liter v8 vortex???

[japajill]

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

[BoxWrench]

@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

[k0ent]

@BoxWrench

if your saying that pressing the piston pin IN would damage the connecting rod, then how do you remove it without damaging the connecting rod? because i asume that, after what you said about damaging the connecting rod if you would press the piston pin in, you would damage the connecting rod by PRESSING it out, or am i overlooking something here?

[dwnrety1]

@k0ent when you press the pin out your not putting 2 edges against each other as you would by trying to press the piston pin in..

the walls of the piston pin will just slide out of and away from the connecting rod without scratching or marring anything.

i hope this clears it up for you.

[k0ent]

@dwnrety1

thanks, got it now

[oldstyle1957]

i like the full floaters

[randomguyfromtexas]

lol doing by hand SUCKS!!! thanks for telling the truth!!!

[lyciferakos]

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

[BoxWrench]

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...

[gtdrummerdude]

Hey do you think i'll be able to press piston pins out of the pistons on a 302 Ford motor with a half-ton arbor press? Or will I need a stronger press?

[pantherxx010]

I remember learning this when I was taking auto class in RCC that someone help to pop the pin out and did this heat thing and pushed pin back in. why pop out be cause he install the rod in the wrong side.

[BoxWrench]

There will be no side to side movement once the piston is installed into the engine.

The connecting rod fits to it's journal on the crankshaft and once all pistons and connecting rods are installed, the piston is constrained to it's cylinder bore and the connecting rod and piston pin will only have a few thousandths of an inch lateral movement (rod side clearance)

All of this makes more sense when you see the entire system work together in the complete DVD... It's a lot of moving parts

[possum66669]

lmao doing this by preaty much just sucks lol i love it

[helpcurecatholicism]

these vids are helpfull thank you

[Bran247]

Ok,,sorry

[BoxWrench]

Just busting your chops Bran...

Hope you liked the video, glad you posted.

It's nice to know people are paying attention to all the time we spent writing and making these video projects.

[yehudiadelphos]

I'll say, I'm very impresse. Thank you for this presentation, it's greatly admired

[Bran247]

Now why in the world does he state "the rod has to be facing the right way on half of the pistons" ? I'd say it has to face the right way on all 8 of them so you better take the time to situate all 8 pins, pistons and rods!

[BoxWrench]

Funny...

Now that it some knit picking perfection but we respect the attention to details.

The dialog actually says "...facing the right way on half of the pistons and the 'other' way on the other half..." if you analyze the dialog it actually makes a correct statement. The dialog says the first half is the "right" or correct way indicating that if the same orientation was used on the other half of the pistons, they would be incorrect. Therefore, saying the "other" way on the other half is fine

[shaftiee]

i love these video's, who ever put them up, thumbs up, man thanx, lol

i have always looked to find such video's but ther not as complete as these, thanx again,

[miniman1965]

Why don't you use the other rod heater ? it heats 2 rods at the same time and is thermally controlled?this way the rods get heated to the correct temperature each time.

[Auszug21]

@miniman1965 because the other takes longer to do and uses alot of electricty so often you can only use 1 inless you have comercial grade breakers and outlets

[gjessie05]

I tried it for the first time. They were also semi floating pins. 84 svo 4cyl mustang. I screwed up 2 and had to buy them again. They were binding when moved sideways. I sent them to the machine shop and they came back da same. 2 were easy to move and the other two were not. When i finished building the engine. On the way home it started to sound like a spun bearin or piston slap. I just could not rebuild it so i sold it cheap. Im still bum, not knowing what went wrong. Any ideas thanks!!
