stuck piston

Best way is to bolt a steel plate in place of the head. Drill and tap hole in the plate over the pistons for forcing screws. Or you could use a large wooden dowel and wack it with a hammer. This was for a twingle.

Check yer spark plug! JS. LOL!

Re: stuck piston

That's not a bad call. I've got a long m14 bolt I think from a VW that'll thread into a spark plug hole. But that way you do run the risk of stripping out your head. Last time I used it was a garelli NOI, the bolt just crushed straight through the stuck piston dome, but it let me get some penetrating oil into the case, it was the crank that was most seized.

Thats why id rarher just pull the head and use a 2c2 stick of lumber. Get close to BDC then elevate the cylinder with wood shims and continue to drive the piston down and out of the cylinder. The wood is more forgiving and disperses the shock load better.

Re: stuck piston

I use a dowel, as close as possible to the diameter of piston. Did I use a closet pole hanger before? Wood? Or a 1 1/2" dowel? Don't recall. But you get the idea. Saturate the jug in an upright position with PB blaster or penetrating oil for a couple (or more) days, and be gentle. Timely. This isn't the NFL. Once it initially moves, it will continue to do so.

Haha haha...

I will.impart you a sample of the dark art....

aero kroil ...

Aliens made it to clean the cattle mutilator.

Re: stuck piston

Last one I dealt with I hung the engine from the cylinder. Whenever I thought about it i squirted a mix of atf and acetone in there and tapped the piston with a mallet. After a few days it came free. Unfortunately it’d sat in the weather long enough to wreck the bearings too.

Warm up the outside of the cylinder, with mapp gas.

Spread out the heat, add brake fluid. Soak for a couple of days.

1 inch wooden dowel and concave one end. Match to piston's dome.

Dump out brake fluid and reheat, hit with dowel/hammer til the piston barely moves.

note direction and turn crank, while hitting. Will need a assistant.

Re: stuck piston

I've used Coca Cola in more than one engine to free froze up Pistons & cylinders.

Old formula. But my dad just recently freed up an old Wisconsin 2cyl hay baler motor with the new stuff, and it was diet so...

Diet ? I wonder if he couldn't have done just as well using plain water .

Re: stuck piston

I think he really just got it by brute force and ignorance. It's the family way.

Re: stuck piston

Ha . If else fails , get a bigger hammer . ;)

FWIW clean water will break up rust, but water with dissolved salts will allow a currentbto set up between dissimilar metals....

Not surprising .

Water is an acid , as opposed to a base .

That has to be one of the first things I learned in grade school science class . ;)

There is a Dutch saying which translates to "with force you fuck a donkey" meaning that if you have to use force, your doing something wrong.Edited 1 time(s). Last edit at 01/04/19 06:10PM by dutchpuch.

Says the guy who has probably never tried to start a hand crank, two cylinder Wisconsin. Much like fucking a donkey. Sumbitch will bust your teeth out. I imagine the donkey would too.

Ya so not true ! Bigger hammers, heating with torches, large length breaker bars, crowbars and the like is how seized stuff gets done/unseized mechanic wise on most old vehicles of every type,

Just this Summer a neighbor across the street was trying to remove a rear rotor that was seized stuck on a new looking but 5 year old car for a rear brake change, he was banging it with a little rubber mallet and then a ball peen hammer for 15 minutes, I went over there with a 5 pound hand sledge hammer and in 2 smacks it came off.

Re: stuck piston

Yes!!! I usually soak them in some kind of oil. The coke idea seems interesting...... I prefer the bigger hammer method. On my wife’s newer BMW almost every lugnut was stuck. Some ass hat at the dealership put them on super tight. I broke my 3/4” drive sockets internals trying to get them off. Grabed a 3/4” breaker bar and rubber mallet.....nothing. I had some random fence post that was sticking in the ground behind my house. Grabbed a hacksaw boom instant 5’ extension on my breaker bar. Every lugnut went back on with anti-seize. My neighbors we like wtf are you doing with that big ass pipe.....Edited 1 time(s). Last edit at 01/05/19 10:28AM by erich.

If u get. The. Aero kroil it takes a 15 minute soak a little heat optional it will almost fallout. It. Is for getting slag out of your machine gun...
