LS3 Piston Pin Clip Removal

[BajaJoe9542]

I just used a scribe (dentist tool) and snap ring pliers (right angle tips).

But drilling works too

[Ls3guy]

that looks more like a ls7 rod and piston

[modtwenty]

u can do that with a leatherman, endmill lolz

[GOCHELIN]

I WANNA REMOVE THE PISTONS FROM ROD,THE PISTONS AND RODS ARE FROM JEEP 4 LITERS ENGINE,THE PINS ARE PRESSEND,AND THE PISTON IN THE SKIRT DONT HAVE ENOUGH MATERIAL TO HOLD,WHAT U THINK IS THE BEST WAY TO REMOVE,I HAVE IN MY HOUSE A 20 TON H PRESS,I REMOVE ALREADY THE RODS FROM OTHER PISTONS,BUT I DONT WANT DAMAGE THAE PISTONS(FROM 4.O JEEP)BECAUSE I NEED FOR MY STROKER POOR MAN KIT :(

@GOCHELIN First step is to turn caps lock off. Noone likes someone yelling at them.

[Oldbmwr100rs]

@GOCHELIN You don't need to yell..In this case perhaps heating the pistons up to a little over 200degrees F will loosten the pins, then press them out. It will take a press to do it still, but you're less likely to gall the piston pin and piston. The manual should have the proper info for you as well. Remenber, heat is your friend!

@Oldbmwr100rs I AM NOT YELLING PPL,THAT THE WAY I WRITE AND SORRY IF A BOTHER SOME ONE :(,AND I THINK I GO TO MAKE A VIDEO I HAVE THE PRESS AND THE RIGHT TOOL(I FORGET THE NAME OF THE TOOL LOL )

[longlovesmer]

is there another way to do it beside drilling your pistons? like some you can do it at home yourself..

[Andalite789]

Titanium rod hmm sounds expensive

[lyciferakos]

nice job

[ezcondition]

most of the time in an overhual you don't reuse the piston anywas. so it does matter to make them reuseable. the aftermarket made it more efficient for GM to make a throw away part. nothing wrong with that.

[autophyte]

I guess you're right. But how much more could it cost GM to use a circlip with turned in ends, just in case one wanted to remove them?

[autophyte]

I'm absolutely disgusted that GM are making engines so disposable that you have to buy a whole new piston-rod assembly if anything goes wrong with either part. I reckon that they'd like to eventually make the whole engine non- repairable- just slip in a new one if anything goes wrong. Or better still- get a new car.

[MrGuvEuroman]

So how would you do it if you were reusing the piston John?

[fiatnutz]

The pistons would have the notch already machined/cast into the piston to facilitate the clip removal. These pistons could be reused as I machined them.

[BLOODYCLQ]

@fiatnutz mate, my ls1 conrods and piston heads connected together with wrist pin by heat and pressure, there are no snap rings used, I have removed wrist pins at friends shop for free by pressure machine, that was easy, I did all reconditioning work to the engine myself, now I wanna put the heads and rods together, but machinery shops ask me 45-65 dollars for repining the each wrist, nearly $400 all up, I am on low budget any easy way I can do it myself? thanks

[freonr2]

Yikes, why did they design the lock like that? Seems silly. Is there some sort of magic factory tool to do that or does Chevy expect you to throw the pistons away?

[fiatnutz]

Not sure about why GM would design something like that - maybe they think this is a throw-away engine, not an uncommon practice w/manufacturers. Yes, the manufacturer does have a special toiol for installing the clips.

[citydriver]

pretty nifty

ya havent made a video for a while been busy guess?

[fiatnutz]

Have been busy on this end nad not had a lot of time for video work. Will try and get some more stuff posted as I have time.
