67, 901/07 transmission match 2.2S?

[Burint]

Hi,
I bought a1967 911T, the engine isn't original.
It's the 1971, 2.2 911S. The transmission is 901/07
In the red book, it said the tranny fits 1967, 911T and S
Do you think this 901/07 can be matched with the 2.2S?
Thank you
Burint

Yes, but to do this you need to have the flywheel for a '64-69 911 bolted to the end of your 2.2's crankshaft. It will bolt right on.

The earliest 911s have a sort of deep dish flywheel with the starter gear machined into it as one piece, while those from 1970 on have a more flat faced flywheel, with a separate ring gear bolted onto the assembly on top of the pressure plate (in order to place it in the same position so the starter gear can engage it).

But all the flywheels and cranks from '64-77 were attached with six bolts in the same pattern, so flywheels from those models interchange.

You don't say whether this is a running car (in which case most likely it has the right flywheel, or else something much more complicated was done to make the clutch work), or whether it is in three major pieces - chassis, engine, and transmission - and they were never all put together and the car driven around. If you can drive the car and shift gears, you ought not to need to worry.

Walt,
Thank you for reply with all details. When I bought the car, engine and transmission were put together. The car was a running in the past but was in garage for 17 years.
My mechanic took everything apart and store in the box because we don't plan to restore the car right away. I will check all the pieces as your recommendation.
Thanks

I thought the flywheel increased in size by the time the pull type PP came out. Then, didn't the bell housing become different? Not saying it won't bolt up, just saying that maybe there's something to think about. Sounds like he's going in the right direction, though, and there will be room, rather than trying to use the flywheel and PP from the 2.2 on the 901.

Oh wait, that's what you said, huh?

(Going to be) running the same set up (2.2S motor with a 67/ 901 car). Right way to go is as previously mentioned- use the flywheel from a 2.0 car and it's a straight bolt up. Major diff is the large diameter wheel used for the 2.2 (225mm I think). I don't know what you paid for your car 17 yrs ago, but your motor alone (if complete) is likely worth $6500-$7500 in my neck of the woods as a core alone.

BTW- be careful in 1st gear!

[Walt Fricke]

One must separate the clutch disk diameters (215 vs 225) from flywheel or assembly diameters (which means the ring gear, as it sticks farthest out). The design of the 901 (or, if you will, 2.0) flywheel left room for a larger disk inside. This required an entirely different flywheel and pressure plate, plus the separate ring gear, but they all fit in the same three dimensional space.

Hence all the interchangeability. Of course, if you get off the beaten path you start dealing with other differences - the splines on the trannsmission mainshaft, or "push" versus "pull" pressure plates, and related throwout bearing and actuating mechanism issues.

But Burint doesn't have those to deal with, it seems.

Burint,

What is the VIN of your '67? The 911T didnt come out until 1968. You never did post it in your other thread. From the look of the gauges it's a pre-68 because of the green lettering.

Engine number 6311665 (I think I'm reading that right) that's definitely a '71 S, should be engine type 911/02.

I would look around for a '67 engine (aluminum case) and AFMSX trans, a RHD car is kind of rare.

Ok guys,

There are a lot of issues here.

A 901/07 is an aluminum case transmission from an early ’69 911. I think (but I’m not absolutely sure) that you can change the transmission 108 mm axle flanges to the 100 mm short axle 6-bolt Lobro ‘simplified’ version from late ’67-’68. This may require a differential change. These are things I intend to determine.

A 901/07 will not bolt to SWB axles. I don't think there are any Factory intermediate parts to adapt. I was able to do this (911/01 to SWB) only with custom parts.

I think Walt has it correct.

There are two clutches here; a ‘push’ 215 mm common to all ’69 and earlier and all 914/914-6. There is also the ‘pull’ 225 mm clutch starting with ’70 911. The cutch changed again in ’72 – not diameter (but input shaft splines, release bearing and more).

Basically there are three in this era: pre-’70 2.0 215 mm, the unique ’70-’71 225 mm and the ’72 and later 2.4, 2.7 (and even 3.0 and 3.2) 225 mm. The early one has the ring gear integral with the flywheel and the later ones have the separate ring gear on the pressure plate. There isn’t any issue with starters. Even the latest still fit the early transmissions with the proper clutch parts.

A big issue between the 2.0 clutch and the 2.2 is the pivot is in a different radial position relative to the input shaft.

Best,
Grady

Didn't catch the question was two parted until I re-read. 1- will the 2.2 bolt to the trans w/o problems? answer- resounding yes. 2- Will the trans bolt to axles from the early SWB? I'm trying to find that out myself now. I've actually mailed my early axels to the shop who is rebuilding my later 901 trans- I'll post and let you know how it works. I think worse case scenerio would be that you need to buy new axles.
- And I typo'd- Ment 225 mm clutch- not flywheel... read what I mean, not what I say While your in there, I'd consider replacing the pressure plate with a higher clamping unit (KEP makes a nice one). Don't think the stock pp would be a problem but it seems like cheap insurance. Your 2.2 makes over 50hp more than the engine it's replacing.
-- +1 on the VIN check- I saw that "T" and didn't want to point out the obvious. Range for 67 should be:
1967 normal Coupe #305101 through #308522 # produced 1600

Hello John,

My mistake about the T , my 67 Vin is 308328

Engine number 6311665 (I think I'm reading that right) that's definitely a '71 S, should be engine type 911/02.

That's correct

Very hard to find in Thailand

Here's the picture of the 901/07 and the clutch set up.
As I explained these were the set up the first owner had in this car. I don't know if this is function properly back then because the car is not driven in the past 17 years before I bought it. I hope the pictures will help other experts to determine if I have the correct set up or not.
