RE rebuilds - the inside story!

[13btt]

Have you ever wondered what your rotary engine looks like inside?

Here are some photos of the rebuilds we have completed to date. You'll notice that it is very important that all component parts are cleaned to a high standard to ensure high compression, smoothness and long term reliability of each component part.

I have also included a photo that shows a destroyed aluminium rotor housing after the apex seals shattered and scored the internal surface - nasty!

One other photo details the effect of allowing your rotary engine to sit in the rain (i.e. like at a chop shop or similar. Now that photo is a little extreme but still gives you an idea how rust seizes the apex & side seals into the rotor - no compression there folks!@

Happy viewing!

More photos

Here is the second batch of photos...you can see the engine coming together starting with the front housing, then the front rotor & housing and the centre iron housing in place.

Is your engine starting to make sense??

 

[13btt]

Ok this is the last batch of photos...

You can now see the "sandwich" coming together nicely and is almost complete with both rotors and all housings except for the rear iron housing in place - notice how shiny the internal surface of the rotor housing is.

You can see in the photo the beers in the background - the more beers the better the engine 8-)

I have then included a side view of all core components assembled. Finally the engine is ready to ship.

The last two photos show a damaged aluminium rotor housing due to broken apex seals and the water damaged rotor of another engine that was subject to rain!

woo... who's that kwai loh there? some aussie rotary guru? hahaha... nice pics glen...

Clean slate looking for high quality paint to cover it in glorious splendour.

Glen....I wanna be your apprentice...... hehehe

Cheers

 

[arsenalboi]

u rebuilding any soon? can i be apprentice? very keen to learn about how it goes together.

 

[Poorman]

how much is the rebuilt cost??

 

[13btt]

Last time we charged about RM5k to RM6k. This initially may seem expensive but cheaper in the long run since our engines defintely last longer the 1 year of other 'inferior' rebuilds with my ex RX-7 still running around 5 years on since build.

I regret to inform all that we are no longer building engines due to time constraints on my part and quite simply the money doesn't justify my time and effort - sorry. The 15 odd engines we built were fun and enjoyable for the most part but, though not enough.

Best regards,
Glen :shades_smile:

then you should give a free class on engine rebuilding.
all those who are interest join together... for a day.. from morning till night... rebuild and necessary mod to ensure engine efficiency and lasting.

the legacy should continue on.. :) ..... RE lives forever....

Dont think we can do it in 1 day. You need a fundamental knowledges, a good mechanical background and technics.
I believe when KC and Glen started to rebuild back to few years ago they had many studies, practices, the trial and error. These made them have their own skills now. Not to mention how much time, effort & money they had spent on.

 

[Alchemis]

possible........we don't need to make sure all attendees know how to build the car within a day.

but a demonstration and things to be aware of during rebuild. also the best known method developed through experience.

all these one day can gao tim... i provide beers :)

the rest will all depend on the attendees if they want to start rebuilding themselves and gain their own experience.

 

[theseira]

Cool, count me in. Alchemis brings the beers....everyone else bring some food and dessert and we can all have a pot luck meal while understanding the rebuilding methods of a rotary engine. Hee Hee!! All we need now is some of Tsuchiya-sans girls to hold up the boards. "Just joking".:mouth_closed:

 

[phat7]

i wish it was that easy. it is a time consuming project. no way in hell it can be done in one day. cleaning alone takes 1 full day.

 

[Alchemis]

hmmm interesting.... maybe we need a 2 days class then :P

I want to learn how to build rotaries =). So any good workshop manuals to start with?
I'm practically a dummy when it comes to engines.
Ok i know how to hold a spanner and theory bits. But bugger all practical.

 

[saru-kun]

VICTOR the hell are you doing here?!!! Lol...nice to see you actually coming into zth hahahaha...

I can send you the factory workshop manual if you like?

See you in msn.

Cheers

Haynes manual comes to mind... except that the car shown is left hand drive (USA) so you have to re-orientate yourself when it mentions "driver-side" or "passenger-side".

I've one but never done an actual rebuild myself... yet.

 

[Alchemis]

no difference left or right... just that the US model have a few things extra and our JDM does not have.

 

[saru-kun]

I've yet to see a publication on Haynes on the RX7, not the third gen at least. Had a quick google just now and only Haynes USA publishes manuals for the '79 - '85 and the '86 - '91 RX7s... while Haynes UK only does the '79 - '85 version.

Haynes Australia doesn't even have RX7 in their Mazda lineup of publications. Anyone's best bet is still the factory manuals.

Am currently still contemplating whether I should splurge out and buy DIY-RE's set of four dvd on the rebuild and/or rotary aviation's video by Bruce Turrentine...

Or

Just be cheapskate and stream videos of here:-http://www.rebuildingrotaryengines.com

dev got the DVD... but he misplaced it... i'll try to page him if he finds the DVD or not...
