Angry Seized engine

Hi all, my first post here.
So, I am trying to get a 1977 GL1000 back on the road. The bike is in pristine condition. Stored inside.
The engine is seized, and no matter what I do, it just won't turn over.
-The bike is in neutral.
-Pulled the cylinder heads cause I need to change the gaskets.
-Found some coolant inside cylinders.
-Tried to put the bike on 5th gear and move it back and forth. (Didn't work)
-Removed the engine. Sit on a side and purred some penetrating oil on top of pistons. Let it do it's magic. Flip it over and did the other side. Both sides sit for a days. Nothing happened.
I used brake fluid, and still the same.
Used rubber mallet on pistons, still nothing.
Hot wired the starter, and it couldn't handle it.
What are my other options beside splitting the engine?
I am sure if all that didn't do anything, pulling the halves apart won't be easy.
Thanks

Welcome to the forum, Rocks.

I think you're on the right track but need to let the oil sit longer. Maybe you could take the back covers off and make sure nothing is going on with the clutch or stator.

Could you please fill in your profile. City, state and bike. Someone in your area may know of resources or be able to offer some hands-on help.

What the years have done, cannot be fixed in a couple or three days even with good penetrating oil.

you are going to have to be VERY patient, and allow the penetrating fluid of choice to sit on top of those pistons for a couple of weeks.

The cylinders facing up, generously doused, and the engine oil sump filled with plenty of penetrating oil solution inside to help the other side pistons on the back end of each.....

let it sit for 3 weeks IMO, then turn the whole engine over, and repeat the whole process.

after the 2nd side is done, you should be able to use a mallet and a wooden 4x4 or smaller, what ever will cover most of the pistons, and tap them fairly hard, each one in turn, don't try to turn the engine over just by hitting on one piston... that will break parts.

after each piston has had a turn at being tapped, use a break over wrench and start wiggling the crank shaft back and forth. the big rubber mallet, or a long 2x4 as a hammer will work good here.

don't get in a hurry with a sledge hammer, you will ruin the motor.

My brother once took a 283 Chevy V8 which had the manifolds removed, and it sat under a drain spout for a couple of decades.... he used this process to break the motor loose and very gently got it to moving.....

once it would turn a full revolution, he turned it over by hand many times.

then he fitted a starter to it, and ran that for a very long time with more penetrating oil....

then he put it together, started it up, and drove it for several years.

You could buy one of those cheap rubber mallets and cut the handle off so the head will fit into the cylinder. Then you can bang on the end of it without damaging the piston top.

Great, I will give those tips a try.
The kick starter was also jammed. So, I had to take apart, and with a help of a hammer and I was able to get it freed.


Thanks guys

Hum,wonder if it may have broken the primary chain?Pretty sure that would lock the motor,put a wrench on the front of the crank and try moving the motor.

If you want to ride the bike soon. I would look for a replacement engine to use until/if you get the original running.

I've learned so much from my mistakes, I'm thinking about making a few more.

I think it is way premature to attempt that right now, and would risk unwinding the bolt on the crank if he tried to go backwards with the wrench

There is no valid reason, right now, to attempt to roll the engine over, until the solvents have had time to work.

John,I think all the oil he has poured in the motor it SHOULD have done some movement by now,unless it is completely bonded piston to wall,with just the rings rusted up it seems like it should have moved some.Some caution will indeed be used to keep from more damage.

PB Blaster worked great on rust.
