Sorry Tony for not answering before, but I must have overseen your reply.

I only bought the apex seals at RotaryAviation, only took a week to get here O-rings and other stuff I took uhh got at work

Rest of the seals and FD cornersprings I bought at my local Mazda stealership.
Next time(my current motor) I will buy all the seals and stuff at R.A. as its cheaper.

So today Oliver(OC94Rx7) and I rebuild my motor.

It was easier than I thought, but some parts were hard to remember because its like four months since I took it apart.
Only real serious problem was fitting one of the Apexseal springs on the rear rotor, it ended up falling into one of the watercanals, but with a little physical ingeenuity involving a long *** screwdriver and a magnet we got it out
And after looking for a lost thrustwasher for half an hour and going through the garbage, it turned out to be located on the back of the front counterweight

Anyways here are a few pictures.
I used After run oil as used in R/C Nitro motors for the lubeing of internal parts.

 

TAAADAAAAAHHHHHHHHH

Shortblock is finally done, now with a little more

 

forgot picture

 

And there were no parts left??

//magnus

 

Not alot, only a few washers that got replaced and 12 rubber cornerseal inserts which I decided wouldnt go back in because they were kindda rotten

 

Looks good kim!!

Hope that baby will fire up without problems...

 

It's gonna smoke....thats for sure!

I was just there to give a helping hand. Make sure Kim had some good music playing, eat right (not just candy bars) and add some comic relief.

It was fun Kim bigthumb:

 

Oliver,

Did Kim survive the depeche mode anslaught of last night then??

I wonder how good that model oil stuff is gonne work

 

Nice job, Kim!
Did you do any porting or so while she was open?
I'd like to know how the rebuild went, and how well the engine runs afterwards, as I'd love to rebuild an engine too, just to learn from it. Since I have a very useable 12A core here, a bridge ported 12A is within reach
Any problems during rebuild? Any really special tools needed?

 

Thanks boys

The Irons has been ported as pictured earlier in this thread, Primarys are kindda mild but with more duration, secondarys are medium/big and 5/6th ports are big/large.
I have finally learned to TIG weld so I will make some custom cold air intake.

As mentioned before, it was easier than I thought, just make sure you have the rebuild kit required before attempting because some of the parts were kindda hard to remember. I got the rebuild video and watched it a few times and proceeded on by memory

I dont know about the flywheelnut on 12A´s but its a 54mm on 13B´s and requires an air-impact gun to get it loose I took it to a local mechanic and gave him a handfull of beers to do it, works every time
Other than that you need the usual Mazda sized tools(10,12,17 & 19mm sockets) and a torque wrench or two.

 

hahaha No depeche mode.
I played some Korn for Kim. Good rebuild rotary music!! Also because the bass and drums kinda sound like a rotary motor turning! Maybe, thats just me thinking that?

 

Oliver, no idea there But Kim was going nuts last night over his neighboors love of depeche mode so maybe you should consider buying him a CD for his birthday

 

Flywheels on 12A's or 13B's are all 54mm, and an impact gun doesn't even always work! The best trick is to use a huge wrench (the wheelwrench for trucks is great if you don't have the Mazda one) and have a pair of feet (not your own) standing on the "lip" of the rotor/sidehousings. You need to remove the oilpan and pressure regulator first. Then just jump like a maniac on the wrench. Works most of the time. It even worked when I couldn't get the nut loose with an impactwrench!
Your are right about the beer: it always works

 

The motor will go in sometime during easter, I have borrowed Pers garage.
But I could use a helping hand one of the days Oliver

 

I can help you on either Sunday or Monday...next week

 

Ill come over tomorrow night, I need measurements for bolts.

 

Tadaaaaaaa My motor is running again.
After priming the fuel system and five seconds of cranking it jumped to life for the first time after the rebuild

After a few minor adjustments it idles at 800 rpms

Here is the motor allmost ready to go

 

Oilpressure seems a bit high though

 

Motor is done, the install took all easter, including beerbreaks and stuff.

Once again thanks to Oliver (OC94Rx7) for helping me out

 

Lookin good Kim!!! I like you dash!

Whats with that pulley up front? Looks nice!

 

Kim,

Did you find out what's up with the oilpressure?
Shouldn't go higher as 6 Bar :-/

 

It might be the 20/50 weight oil it seems pretty thick for only 10 degrees celsius of freezing danish weather

 

I've sent the waterpump today Kim, hope she'll be better then yours now.

 

Hey Kim

I thought you where running an electric fan? Or is my memory failing me?
