How to separate a piston from a connecting rod 

When you're finished heating those pistons, could you cook me up some Valvoline stew in that pan? Maybe with a hydrocarbon garnish and some Exxon spice mix?

As a quick note, you should mark the rod to know which side faces to the front of the engine, before removing it. It can be installed wrong, because it will fit either way.

Good stuff for us folks who don't have all the fancy tools others do. Thanks!

Just did this bain-marie trick with my OEM pistons from a CA18DET-engine (as found in EU 200SX) - I used one old headbolt to lightly hammer the wrist pin out. Thanks again!

You don't need a machine shop if they're press fit you just need a badass torch and someone that knows what they're doing

easiest way ive found is to have someone tow ur car at about 60 miles per, throw it it first and drop the clutch. sometimes it removes more than the piston tho.

I’ve got a TRX400ex and my wrist pin is one with the rod, I’ve got it to move he slightest of a 1 billionth of an millimeter, enough to make the piston not move freely. BUT THATS IT! I tried to heat it up, and tap on it hard while holding the piston still so it didn’t damage my crank or bearings. NO luck. The clamp method did NOTHING. Now, I’ve got my extension stuck in it because that’s what I was using to tap it. No idea what to do now :/ Gonna try to call a shop and see if they can do anything for me.

pressed in pins can also be removed using the same method (heat to expand) be patient

Dumb question, but since your rods have floating wrist pins, I assume they're 20mm? Early 4AGE's have 18mm press fit wrist pins. If you have 20mm ones, I believe you have the later, stronger, 7 rib 4AGE block too. Just trying to confirm some of the info I've been reading online :) Keep up the great work! I find your videos very helpful.

Nice video. My engine seized 7 rib 4agze.. In the process of rebuild. Just ordered wrist pins.. For the install do the pins just slide in?

What about the piston with no circlip ....how can i separate my 4g63a piston

why am i watching this im not even old enough to drive legally

IS this what shot through the bottom of my 99' f150 v6 4.2l oil pan when knocking noise was on freeway? do i have to buy another engine, or drop oil pan and fix this connecting rod?

nice!!

Piston soup, sounds delicious.

excellent

Nice

this is piece of cake How would u remove wrist pin from conrod?

The that piston head can handle a explosion but csnt handle the heat from the pot?!

My manual says not to separate them, your MR2 must be different, mines an 1983 supra

Como hacer delicioso caldo de piston.

I just use a press to push the wrist pin out, don't need a machine shop.

My wife would whip my ass for doing that in the kitchen.....

Well wouldn’t it help if it wasn’t laying on the table but held up so ok

I loved your video 👍👍👍👍👍👍THIS MY ADVICE 👍👍👍👍USE RIGHT DIAMETERS LONG SOCKET ONCE YOU WARM IN WATER✌️✌️✌️✌️✌️👍👍👍👍👍

Uhh my pisten don’t wiggle

I thought it turned into a cooking video lol

Hi welcome to chillies how may I help you

Peter piper picked a peck of pickled pressed in piston pins

If you used carb cleaner and get varnish off it will come right out

Yeah, what a pleasure. Now i can give you an advice. You dont need water, just use an old electronic stove which you dont use for cooking anymore, that you can use as a heat plate and put the assembly uside donwn on it. Of corse before you do that, you have to remove the clips and switch on the stove max 50% power is enough. As you said aluminium expands faster than steel. So you have just to wait and monitor the situation. If you wait to long the steel will also expand es much as the aluminium and its to late. If youve done everything right, the pin will just fall out of the hole, as you hold the assembly sideways, pin down. But be cerful with the pin and rod, because they also will heat up. I suggest stove/ air instead of stove water, bacause in water the temerature is pretty even. By just using a stove the heat needs to creep up the piston material and will spread through the piston, while the heat transfare between piston and pin will be relativly bad compared to water, which surrounds every surface of both materials and will heat them up with a nearly even rate. You can use this technique also with a ball bearing stuck in a gearbox housing of an motorcycle f.e. . Just switch the power on 100% of the stove and put the housing with the gasket face on the stove ( gasket removed) so the bearing will face down. Gravity will do the rest and the bearing should fall out in a few minutes. I did it my self, bearing in housing and piston pin in oem piston. Belive me, it works ✌

That’s 1 piston 11 more to go

LIKE ONE VIEWER SAID 👍👍👍👍MARK PIN👍👍👍👍👍WHICH WAY COME OUT✌️✌️✌️✌️

yummy piston soup

You didn't need hot water! Next time use a socket that's the same size

Man's breath sounds like deflating balloon

ha ha press fit piston pin

Well WD40 isn’t always gd to clean off inside engine parts but Cool

For all the stress and time wasted doing this you could have gone to Harbor Freight, bought a 12 ton press for $99, and gotten all the wrist pins out.

You talk a lot then doing the actual work 😚😣

Buy your wife a better stove, my wife's induction stove would have had that water boiling in 30 seconds flat.
