RX-8 side seal TSB
 

I have this RX-8 FSM but i get different suggestion on lenghts/part numbers from Mazdatrix and they say Mazda has changed the tolerance since the printing of the FSM. There was a TSB several years ago that changed the recommendation.

Here is picture from my FSM

Anyone has link to TSB where it was changed?

Thanks!

wrong info removed, I guess :lol:

I would really like to find out some official info from Mazda, as Racing Beat just emailed me same specs which are in the FSM page i posted.....
Now who is wrong and who is right?

Honestly, Mazda"s spec is always a bit loose. I keep my side seals at was it 0.025 as much as possible when mazda said it is ok to have 0.06 and thats for fc.

Its a pain to hand grind the seals for FE but easy if u have a bench drill setup with a dead rotor

Mazda introduced a 5th Side Seal from November 1 , 2008 Production.

For Rotors marked with V,W,X,Y.
N3Z5-11-C10 Side Seal

I go with what your Rotor is stamped with F to U...and select to appropriate Side Seal as per FSM.

I know of NO TSB concerning Side Seals, but will check again.

Yes, i have 2008 version of engine build manual too :

but its not playing with Mazdatrix website (and Geoff from Mazdatrix claims mazda has changed info which we read in both those FSM's)

http://rx7.cz/pics/mazdatrix.jpg

so..

This PRODUCTION CHANGE WAS IN November 2008, which is AFTER any information you have.

Just how many 2009 MY Series 2 Renesis 2 Engines have been rebuilt???....none that I know about.

Mazdatrix or anyone else can claim what they want they are NOT authorized by Mazda, to speak on behalf of Mazda, they earn a living off Mazda.

Again the MAZDATRIX website is incorrect, there has never been a B C D E stamp ROTOR in any RENESIS Engine series 1 or 2.

From Mazda's EPC.

BTW: There is nothing to stop a Mazda Dealer from doing Rotary rebuilds, it is fallacy to believe that Mazda does not allow it, under warranty Mazda expects their Dealers to use their re-mans, outside of factory warranty they can do what they want...The issue unfortunately is there is not the expertise or will in Dealers to tackle rebuilds, then add the higher labor costs and overheads, what owner will pay?.....how many franchise dealers do re-builds of any engine.

Go with what your MAZDA manual says...it IS correct and the information has not changed in neary a decade of production, only added to with the N3Z5 Side seal used in late 2009-2012 RX-8's.

BTW: There is NO TSB on Side Seals..

The legend that Mazda dealers aren't allowed to do rebuilds comes from the "White Glove" puffery in the 4206f recall material. Too bad Mazda didn't arrange for quality rebuilders. They also cost their dealers the opportunity to learn the innards of the rotary.

Maybe I'm showing my age again, but I remember a time when dealers did rebuild engines. Rebuilding a piston engine is a much more familiar process than a rotary. I'd guess that any good mechanic who knows what to send out for machining can do a decent rebuild.

Ken

Nobody knowledgable uses that info anyway, typical noobery

Yes Ken, we used to do all warranty claims and rebuilds at my Mazda dealership for 10 years or more...and the odd retail non warranty job.

Then the "experts" started up businesses in the 80's, just like the US.
Mazda Dealers lost it all because of their costs..$6000+ for a rebuild!!!

Today, I see very little skill at Dealerships 'in our un-plug throwaway world'.

There are good and bad.

I thought they made some revision on the side seals for a bit tighter clearance ? correct me if wrong ... could be a bit mix up with FD or FC? mmmmm

rebuild engines ? ... yeah right, some Mazda dealership doesn't even know how Rotary engine works ... rebuild ? ...

I m going to be buying side seals and going by the letters some say get them longer and cut them , I don't want to attempt that ?

/\

As I said before Mazdatrix are not correct with their # labeling, they use Mazda's Part Number system but reverse the front model code of OEM Part Number for 'their' identification/ordering and then post to the rear of #.

Mazdatrix first one of "B&C&D&E Stamp" does not even exist on any OEM Rotors for choosing that size (length) Side Seal to use/order.

I have included the latest OEM (Mazda) Part Numbers EPC pic for Side Seals and nothing has changed, except this EPC show 'UK' as a destination for use of the N3Z5-11-C10 Side Seal used from Nov 1, 2008 production, IF the new Rotors required this length and had a V,W,X or Y stamped on Rotor's Corner Seal face area...these N3Z5's are the "Extra Long" Side Seals which can be filed to suit any Renny Rotors IF you want to go down that path....one time years ago, that is all we would use, and the then flat profile Side Seals were always filed to fit (we would use a Breaker Points file).

So Chino rx3, you have to decide on which way you want to go with your Side Seals.

I'm not going by mazdatrix I notice that, but the question is if I order from Mazda I get whole sale price do I still need to file or will they go right in depending on letter. ?

If your builder doesn't know that, change builder Chino.

the side seal will fit as long as it matches the corrdsponing stamp, look up the fsm. in fact, Mazda has been selling pre cut seals for looooong time, its just that its never availible in us until rx8

and yea I'm with bse, if ur builder doesn't know that, its time to find a new one.

Totally Right about my builder ^ he knows what his talking about and he told me to get them But i see alot of people buying longer ones and cutting them and I was confuse my self ,had some time to ask questions., My builder is setting up 2 cars for track so I dont want to be calling him and questioning him. He is not the forum type of guy he a track kinda guy .. Been building for years. I read alot here and confuses me when I see people talking about cutting seals are better than precuts so it threw me off, Thats all, Thanks guys.!! :-)

IF you go by the letter stamped on your existing Rotors then technically you do not file the Side Seals...that is the idea.

I am not going to get into the 'argument' of who or what is better, remember we are all experts and Mazda does not know what they are doing...right.

And yeah, I remember the days of filing your own Side Seals, and 'some' builders still got it wrong.

Just for the record, this is the first time Mazda has ever offered a "sized" Side Seal size options...in Renny.

FD and FC Turbo has only one OEM Part Number, N3Y1-11-C11 Qty 12.
FC has one, N3Y6-11-C11 Qty 12...which supers to N3Y1 used on the Turbo's.
All Rotaries before that used 1011-23-151A and you filed them.

Cut your own seals and make them .002

Thanks I will got this Route , ,,I dont want to go wrong ..

I cant even File my Nails Right , lmao..


Thanks I'm going OEM cant go wrong.!

LOL you can go way wrong with OEM... Your call chief.
