914-6 RRC 2013 Tune Up, 914-6 RRC 2013 Tune Up Options

[map]

Kevin and I started the tuneup for RRC about three weeks ago. Yesterday we learned more about the hodgepodge that is my car. I ordered a clutch kit and Pertronix ignitor for a '76 911. The flywheel delivery was more than two weeks out, so I decided to wait on it else the car likely wouldn't make RRC 2013.



It turns out that my old flywheel is not from a '76 911. I'm not sure of the vintage, but it is slightly smaller. I can't find anything about this part #, 901 102 205 0R. I'm guessing it's from a pre '72 911 or from a 914-6. Any ideas.





Since I couldn't get a new flywheel in time, we will reuse the old flywheel and clutch and save the upgrade for sometime in the future.

The other issue is with the distributor. Turns out it is from a '72 or '73 911 (0231 169 010). Have to get a different Pertronix ignitor.



Now I'm questioning whether my engine is a '76. Is this number from the left head the engine number (901 105 111 1R)?



Thanks for your support.

your distributor is a 1973 model

[majkos]

any suggestion on making a better feeler gauge for a 2.7 ?

Long reach, narrower, and at a 90 degree angle.

[brant]

bend one.

they sell little ones with a handle and a 45degree bent tip

but you can take a standard feeler guage and just 45degree bent the last 3/4 of an inch on it.

Do you mean RRC 2012 in 2 weeks? If you mean 2013 you have plenty of time (IMG:style_emoticons/default/poke.gif)

[brant]

all of the 914 trannys need the 64-69 flywheel (6 bolt)

I think renegade makes some conversion ones
and if you had a 916 tranny you might have a 70's flywheel

take one more picture of the one you have.
back up and get the whole thing

but odds are its the early 2.0/6 flywheel
and if so any 4 or 6 914 clutch should work.
you can probably get a disc at the local auto parts store
just buy a 914 clutch kit (the 6 cylinder ones are probably all that is sold now, they have more springs for less stutter as you start out in 1st gear)

[sixnotfour]

This one works well...I bend it to a 90..

[sixnotfour]

There is alot of meat on 901 flywheels ,, As long as the grind the friction surface and the clutch mounting surface.
dont forget a washesr undr the pivot stud if you have it resurfaced.

Like Brant said lets see a pic of it.y

I had a starter take out the flywheel on my 2.7. I'll try and find the paper work as to what it was replaced with. Problem is, it may take a while to find the paperwork because I moved from IL to TX and things are in boxes.

This.



from the pics, that is the correct flywheel from an early 911/914-6. Did you get new bolts?

I have a huge binder of info (all printed from either this site or Pelican) from doing my conversion. Would you like to borrow it? I can pick it up on Thursday and drop it off on friday. Let me know.

Ooooh! I like this!

really like the curve part for the fingers.
that way the wrist does all the twisting while ya trying to slip the feeler gauge, under the swivel foot!

we've narrow down the motor to be a '73
what's the "proper" spec. feeler gauge depth to use?
or what ya recommend?
we also know the motor "built" for Auto-x'ng

I'm seeing from .003.75 to almost .006 mm (IMG:style_emoticons/default/confused24.gif)



Thanks for the info all you folks has to share, deadline is looming too close! (IMG:style_emoticons/default/hissyfit.gif)

[brant]

a 1973 would be a 2.4

what is the engine type number on the upright near the fan?

[SLITS]

Valve lash is 0.004" on all, cold

That is the correct 6 bolt flywheel to mate with the 914 transmission (the one with the 901 part number).

The stock six is a 215 mm clutch. The other disc is for a 915 setup which is a 225 mm clutch and the hub is larger diameter / coarser spline.

If you wanted a 225 mm clutch you either get a hold of a '70 - '71 911 transmission and have it converted for 914 use (911/901 tranny). The clutch kit for that setup retails at $800 as it is a "pull" type clutch rather than the "push" type used on the 914.

or

You have a custom clutch cover made to use with the '76 flywheel and you still have to use the friction disk from the '70 - '71 911.

great info Ron! I'm gonna let Henna give you lot's of kisses from me



Huge headaches to track down with, 'What ya got!?"

FuchifIknow!

[majkos]

we've really haven't remove the shrouding to determine that.
Case #.
So much time taken up on what hell we got here! "You Know!?" (IMG:style_emoticons/default/hissyfit.gif)

[brant]

you can see the number without pulling the shroud
its kinda hard to find at first but then very obvious once you find it

you really want the type number
not the serial number, not the case part number.

[SLITS]

The serial number will be stamped vertically on the fan housing support. Look for a number between two stars .... ie 6?? ????

Behind it, on a ledge of the case, there will be another series of numbers, sometimes not easily seen. They will read 901/?? or 911/??. Like a 911/85 is a 1977 2.7L S motor.

Nice Billy Boat SS Heat Exchangers and Carrera Tensioners too!

I can take an image later of where to look.

[majkos]

Thanks Ron!
Like Brant says, easy to read,
I feel (IMG:style_emoticons/default/wacko.gif) stupid.

anyhow, # are,

911 82

with old flywheel from '69-7?

Dist. a '73

[brant]

Cool, so it is a 2.7
they may have recammed if it has an earlier distributor
hard to tell exactly what pistons/cams

the flywheel should be 64-69
just buy a standard 914 clutch or 914/6 clutch

[majkos]

Thanks Brant!

Pieper sure going to like that info,save $$$$

here's the old set-up,
