Ok, let it be known i have never taken apart a rotary engine.

I hear all the time about how apex seals break, die, or just leave. I was trying to figure out a way to replace these without a complete engine rebuild. I have a excellent mechnical skills. To include machining, and fabricating. So I was thinking(HA!) a rotary engine, this is limited to 12A and 13B engines I have never seen a 20b so im not sure they exist I believe all of you are in a scam to make fun of me when I ask my first 20b question. After studying my engine I noticed I would have to work on the spark plug side of the engine. But i believe in the upper corner the rotor housing, not the side housing, can be cut so that a section can be of a rotor can be repaired and the engine moved to repair the next apex. The few forseeable problems I have are how to resecure the rotor housing and to prevent leaks or warping of the house. It may require filling in of one of the water jacket ports so that a bolt can be screwed in. You guys tell me what you think if its possible.

 

 

Without writing a book about the idea I'll just say it needs to be rebuilt. That way you can actually inspect for damage. 90% of the time when a apex seal goes it ruins the housings

You should not fear an engine rebuild.

 

i dont fear the rebuild, fear is rebuilding a viper engine for a kid who blew it being stupid before his dad gets home. just trying to find better options. And also to get rich on modifying peoples engines.

 

The motor has to be taken apart! You don't repair Apex Seals you replace them with new Seals. No way around it!

 

Wow you sound like you fear somebody coming up with a better way to fix something. freaking commies.

 

No way around a rebuild.. your idea wont work... Do it right

~Mike.............

 

It's not a better way to fix something, it's an incorrect way do fix something. It would take more time and more work to do it your way, not to mention you'd never get it to work properly.

Now figure out what the hell you're talking about before you start calling us names.

 

impossible, no part of the rotor housing is exposed enough to get to the apex seals. you might do a good job of tearing the coolant seals all to hell and end up having to take it apart anyway though.

 

...no

 

Those that have replied are very closed minded people. I think you have forgotten what I said before, I work on engines and do mods for a JOB. I'm not an amateur, I'm not saying you can do this to avoid and engine rebuild, to do a mod like this would require an engine being taken apart to begin with.

And dont tell me about doing something right. Because I've probably built more engines than you ever will. But none of them are rotary. I have put some thought to this, and none of you are even attempting to think about this. You just immediately write it off as cannot be done.

I do believe a better rotary engine can be made. And I am trying to come up with ideas to make the existing engine repair even better. So if you have something negative to say just dont say it.

I believe I asked for ideas, not to tell me it cannot be done. I got plenty of people who say that. Laughing at me is no way to come up with something new. Wow I wonder what the first person to say im going to use exhaust to spin a turbine to swirl and compress air into the piston chamber.

 

Easy.

Just disassemble the engine, replace the seals, reassemble engine. You'll need new coolant and oil O-rings, simplest way is to just get a gasket kit for $100-150 or so, and it includes the manifold gaskets and the like.

It's not a rebuild.

Note that if you do this, do it *before* it pops a seal, otherwise you *will* need to do a rebuild with new housings and rotors...

 

I think thats one of the worst ideas ive heard in a long time. Theres no way in hell that would even come close to working, no matter how big your budget was.

 

It sounds like you don't need any help from the stark amateurs on this forum. Please post again once you finish the project. Thread closed.
