So I am pulling the motor out of my 1980 7 12a motor and the tranny just will not free from the motor to save out lives we dont see any bolts still connecting the 2 that we see maybe someone can show pics of were the bolts are so we can check if maybe we missed one but were lost and it is just not freeing

There are 2 bolts on top and 2 on bottom; if you only found two, you're missing some.

Two bolts on bottom; one under the starter, one on the right side.

Then i got all 4... I thought maybe there was more then 4

nevermind my father just told me that we pulled more then 4

You're pulling the trans out from below before trying to take the engine, right?

Do you have the Factory Service Manual (FSM?)

If not, you can download it here:

Engine and Transmission sections show removal step-by-step, with photos.

Theres 5 or 6 bolts I believe. I think two at the bottom and maybe 4 around the top and sides all removed from the top of the engine bay. god I can't remember.

I counted 4, not counting the ones that hold the starter on, and 2 guide pins.

ok theres the long bolt through the starter with the nut. then the lower starter short bolt that just hold sthe starter to the trans. Then the sunk in bolt hiding under the starter that holds the trans to the engine, then the lower right bolt viewed from the rear of the car by the exhaust manifold or header at the square part of the engine and trans. then there's the two close together ones on the top of the engine behind the intake manifold or carb favoring the passenger side of the car. then theres one by the slave cylinder/oil filter pedestal. I was thinking there was two in that location and there maybe I just can't see it with all that crap in the way but there you go theres at least six if not seven bolts. one of the top ones may or may not just be a nut depending if you still have a stud there or if somone replaced the stud with a bolt at some time in the vehicles past

ok thanks i shall let you know how it goes

then of course theres a prybar you'll more than likely need if your trans has been on for quite awhiloe and it helps to hold the weight of the trans up while removing it from the engine so it slides out of the clutch easier and when you put it back together do the same so you dont bend the clutch plate

rx-7_cbr929

we see 2 that looks like they hold the front and rear housing toughter or do they hold the tranny 2?

Number 6 (top center) is the bolt that also holds the rear engine lifting loop; you normally have to pull that one out, and turn it around backward, so you can attach the loop to the block.

So seven, minus the two that had to come out when the starter came out, minus the one you have to put back in to lift the motor, equals four, right?

So we have the motor out now took anot of work with the pry bar a tad bit of anger and a few bad words but we got it... now we wana tear into the motor because it got ran outa oil awhile ago and it froze up... we have a chiltins and this is our first rotary were tearin into so any advice? or where to start?

DivinDriver

Yes; download the the FSM I linked earlier. It has step-by-step instructions that are better than what's in the Chilton's.

And read it thru before you start. If you've not worked on a rotary before, you cna break or ruin some expensive parts if you do things out of order. Especially if you don't torque/untorque the tension bolts in the right sequence.

Your next big challenge will be getting the flywheel off. 54 mm nut, torqued to 300 ftlbs, and a pressed-fit flywheel.

Search the FAQ setion here for good advice.

you'll need a set of containers to keep all the small seals and springs sorted out that come off the rotors; it matters which location they go back into, if you re-use them.


And bad words definitely help.

so this is pics of my motor and i have one question there is a piece that seems loose where my exhaust header conected to the motor i have it in the pics semi sticking out

4 tranny to engine bolts 1 guide bolt that holds the rear hook, like DD said.

Your picture shows a loose exhaust sleeve. When/if you get the engine apart, you can drive new roll pins in from the side of the housing to hold the sleeve in place properly. I wouldn't remove them.

If your engine actually seized from lack of oil there will probably be several major parts that are not reusable. Here's a thread with, pictures, about disassembling my oil starved, seized engine.

So Im not sure if I should start new thread or not. Because this is not a problem with pulling the motor out anymore. But this is still the same project. So I dont really want to start a new thread, and flood the threads with tons of little diffrent problems. Anyways if im told I should start fresh with a thread I will. Till then im gona work with this one.

So we have the motor out and have it apart. So now we have pics.

1. We are having some trouble getting the front rotor off the shaft

2. The motor was oil starved, So we have some pics of the housing that we are concerned about

3. And is there any way to post more then 5 pics at a time? lol

Thanks for any advice

rx-7_cbr929

Sorry for got to post pics with the last reply

rx-7_cbr929

Looks like the rotor bearing is fused to the E shaft. I wouldn't try too hard to get it off. I'll bet none of the parts in your pics are within spec to be reused.

The chrome on the rotor housings is toast. As someone else said - I would not try and resuse that stuff. Its just tired. Make a coffee table out of the e-shaft and rotor!

Sad news. That's why they put an oil level light on these motors. Without oil, their lifespan is minutes.
