20B Rebuild

[tmann]

I\'m rebuilding a 20B for use in an aircraft. I have gathered a lot of information to get started ..... enough to know that the disassembly procedure is a little different etc.
 
I have a video that walks throught the process of rebuilding a 13B and I have found a description online of the disassembly of the procedure but I would really feel a lot better about starting this with the proper manual.
 
All I have found so far has been the 2 rotor variety. Anyone know a source for some 20B related manuals?

If you get a cosmo service manual, im pretty sure it has rebuild info for the 3 rotor in there. (The cosmo is the car Mazda installed the 3 rotor into)
 
Im pretty sure you will be fine with just some 2 rotor rebuild info...its all pretty much the same. The torque settings are the only real anomaly, but Im sure if you ask a couple specialists, they will be happy to give you a hand.

Yep, the Cosmo manual is what I\'m looking for. They were never imported into the US and therein lies the issue of finding the manual. I figure an Aussie source would get it done.

What kind of aircraft is it being installed in BTW?

[tmann]

It\'s going in a Rutan design Long-EZ.
It is a two place composite plans built aircraft.
Expected top speed will be just shy of 300 mph.

I dont think that the cosmo general service manual has any info regarding the engine rebuild ( I have an scanned copy).  IIRC they didn\'t trust the dealers to do the job so any engines got sent back to Mazda.  I think there may be another manual dedicated to the 20b, try the eunos members website (aus site) as they will probably be able to help.

I know you can get rebuild videos of 13B, 20B and 26Bs so check out some of the suppliers

Ithe Video for the 13B from Bruce Turrentine. It\'s excellent stuff. I checked with the local Mazda dealer to see if he could get me a copy of the manual direct from Mazda. No  luck so far.
I also tried MazdaTrix.com with the same results.
 
If you happen apon a 20B video or reference, please pass it on. I also have someone in Melborne looking for me which seems to be the best bet right now.

Just to follow on from this thread (sorry to bump) I have had these DVDs nearly 2 years and when I got them I registered to get the wall chart with the part numbers and settings/clearances that was made available. I never heard back though and actually just re-registered on the site a few weeks back.
 
The last update on the diy-re site was a few years back now, the guy Lance in the videos 3 rotor site has not had an update in a few years and even his myspace (no im not a stalker lol) has not had any activity in a good few years??
 
Does anyone know if something happened to him, or to the diy-re company?
 
also, does anyone have the wallchart they would mind scanning/copying? Since I\'m now in rebuild land myself!  Don\'t mind throwing a few beer tokens in for a decent scan of that chart!!
 
Sorry for the hijack

I registered when I got my copy but never heard anything back either, no wall chart

+1 would be a really nice to get one :mad:

Last updates on anything I can see was a few years ago, and by the clips and screenshots it looks like they did start filming the other videos. I have emailed a good few times with no response. Be a shame if they are not making the videos any more and (maybe) the company isnt in business any more. From the 3 rotor site he put a lot of money into building the engine room, editing suite and converting the garage for the whole thing!
