Pineapple Racing is launching free rebuilding videos, each week from here on out on how to build a rotary engine. They are going to make it free to download from http://www.rotaryengineillustrated.com

Here is the first tech video they have launched as a beta, and they are asking for input on how to improve the videos.

Check it Out: How To Install A Rotor Bearing Video

Freakin great! I am a great shade tree mechanic and have done all my install work myself on past vehicles but now that I own a rotary I have to learn all over.

Building a rotary engine is like making a sandwich... seriously.

redcivic

I want to learn about timing and such.

ddub

What exactly do you mean about timing?

redcivic

Well, I mean, timing. Installing all the parts so that the timing of teh strokes is correct. Or is there only one way to install the components of a rotory engine?

redcivic

Well, I'm glad he posted it here because I don't have time to visit every forum.

ddub

Maybe this will be useful for you then...

The rotary is very simple. When building the engine the eccentric shaft lines the rotors up a certain way, and the spacing/"timing" of the two is kept the same during rotation due to the design of the rotary. After everything is said and done and it is put together, the CAS (crank angle sensor) is lined up based on the leading/trailing degree positions and the eccentric shaft position. You merely rotate the assembly as needed until it is lined up. That's all you have to do. From there the computer controls the rest.

redcivic

Wow, thanks man that puts it into perspective. The rotary is such a great design, too bad the gas mileage is not great.

I have no issue getting 19mpg city with aggressive driving still, and 22-23+ highway.

The rotatry would be a great design if some ******* didn't invent thermal inefficiency

Why dont we try coating all the internals with ceramic, lol... wait.... hmmmm

ddub

Been done plenty of times.

redcivic

Yeah, although 20 mpg is not good to me. I come from a 12 second civic that still got almost 30 mpg on the highway.

I think it's amazing a triangle inside a kidney, rotating in a 3:2 ratio around a gear, always has 3 points touching the housing surface. Sheer brilliance how it all works out, and 3 power strokes per rotor per rotation.

Also that site is the best to learn anything from. These videos will help very much.

ddub

Personally, the videos (I had a couple from different companies) didn't really help. The best thing I found was just taking an old engine, taking it apart slowly and seeing how it all worked, and then putting it back together. Best way to learn, for me anyways.

'87 Turbo II

oh then I should add "on the internet" and "safely".

ddub

Safely?

Get an FSM, take the engine apart, inspect everything per FSM specs, put it back together in the FSM directions/order and torque to FSM specs. Safe as you can be.

Really all any of those videos are doing are putting the FSM directions into video form.

Has it? Do you have any links?

He was referring to doing a cermaic coat on all of the engine parts, that has been done before. As of other rotary engine videos, I believe there is another engine shop that is offered a video for purchase. Although there is not really any qualified or comprehension free movies to watch as of yet.

ddub

One of the other ones is Atkins Rotary vhs/dvd. It is basically a motion picture version of the FSM. Gives you step by step how to do stuff and the tolerances of everything, like the FSM, but shows you exactly what to do. And I believe there is some NZ shop that is making a whole series of them for porting, rebuilding, etc.

Most videos will be pretty similar.
