The second one says "OEM" and it is less expensive.

I would get the part numbers of the individual parts from Clutch Masters for each of these kits and ask Brian Day at Patrick Motorsports - 602-244-0911. He knows everything about our clutches.

thanks, I'll give him a call tomorrow

but clutches are basicly the same for 901 and newer gearbox and just "hp holding capacity differs"?

[ViR2]

any more suggestions 901vs915 clutch?

[RWebb]

clutch needs to match flywheel diameter.

915 is larger than 901

[ViR2]

Thank You
where can i find the diameters of flywheels?

[ViR2]

Is it possible to get 915 clutch kit and flywheel and use it with 901 transmission?

I dont know what to get, because I have 2.4 engine with original tranny from 912, and clutch is dead. So I must get something

Kristijonas,

There are two possibilities for the clutch size in your 911.

The 1965 to 1969 are all 215 mm diameter. They are the ‘push type’ similar to the original 912 clutch. If the 911 has this 215 mm clutch, there would be no need to change the clutch operating pieces at the transmission and clutch cable.

The 1970 and later clutches are 225 mm ‘pull type’.
If the original clutch from the 2.4T were used then there would have to be many changes in the clutch linkage.

Find out which clutch size you have before you buy any parts.

If you have the 215 mm clutch, there are some VW parts that interchange. This clutch is the same as a VW-Porsche 914.

If you want the larger 225 mm ‘pull type’ clutch, it can be done. It is an extensive project.

Best,
Grady

[ViR2]

so if my car has 215mm clutch, then flywheel should have been used also from the same year, or it can be 225mm flywheel with 215mm clutch?

The point is that it takes about three weeks for the kit to arrive, and if I want to dismantle the tranny and look inside, then that will cost me a lot, because porsche dealership charges a leg and arm for storage So basically I'm trying to guess here

Are there any visible differences from the outside which would tell me that there is push or pull type clutch?

Thank You Grady for Your help

Kristijonas,

The components of the 225 mm clutch are ALL different than the 215 mm clutch. That includes flywheel, clutch disc, pressure plate, flywheel bolts, clutch release bearing, clutch bolts and more. Nothing interchanges. It is all 225 or all 215 mm.

Have someone else operate the clutch pedal. You look under the car. If the lever arm coming out the driver’s bottom side of the transmission bell-housing moves toward the front of the car when the clutch pedal is pressed, then you have a ‘push type’ 215 mm clutch.

To convert to a 225 mm clutch it is easiest to replace the transmission with a Type 911 from 1970 or 1971 911 or a 1972 and later Type 915. This is a big deal. With a 2.4 engine you have two choices: Replace the 215 clutch more often or go to the considerable effort and expense to convert to 225 mm, including transmission.


We need to discuss your transmission.

How well do the synchronizers work?
Is there any transmission noise while driving?
Is there any sign of metal parts on the magnetic drain plug?
Why do you want to take it apart?
There are numbers stamped into the bottom rib of the transmission, under the differential area. What are they?

If you disassemble the transmission for inspection, you need some parts to reassemble it. At least you need all the gaskets and seals. How well equipped is the Porsche workshop? Do they have the tools and technical information? Are the technicians experienced with the 901? What is your availability of spare parts?

Best,
Grady

If my car has 215 then I'll just leave it that way, theres no need for me to upgrade anything

No noise when driving, but it grinds when downshifting to 2nd and 1st. Either way it's an old transmission, probably has not been rebuilt since manufacturing. I'm planing to rebuilt it just for the piece of mind. Yet I think guys at dealership have never seen 901 and very likely not even 915, because my Porsche is oldest in the country right now (not considering two 356 which are in private collection), and the second oldest Porsche 911 is '85
Regarding the parts - I can buy all from dealership, but it costs aprox. 50% more then at pelican parts, so I will source all parts from here.

I'll try to look for # tomorrow if the weather is good

[Grady Clay]

Kristijonas,

I’m impressed!
With your ’65 the oldest 911/912 in country and the next oldest 911 an ’85! !! !!! WOW.

I’ll suggest you learn how to rebuild the transmission yourself. We can help. These are easy if you know what you are doing – we can help. You can make the few special tools – we can help.

Do some Pelican searching on 901, 911 and 915 transmission rebuilds. There is a LOT of information in the archives.

Tell us more about your #994. My dad had a ’66 912 S/R coupe built in Sept. ’65 and took Factory delivery in October ‘65.

Looks like the weather tomorrow will be cold and clear. A cold front must be coming through before morning. At 12:50 AM your time you have 52F, cloudy and falling barometer. Tomorrow’s forecast is for sunny and high of only 48F. Burr.

Best,
Grady

Here's a unique suggestion- why don't you contact our host and actually consider buying from them??

[ViR2]

Thank You Grady.

I've just got back and went to check. I didnt have the time to lift the car and look for #, but it seams that it has 215mm clutch. And I've ordered Sachs 3-Piece Clutch Kit, For Cars With Cast Iron Pressure Plates, 911 Except S (1965-69) and an aluminum flywheel from Spec.

Regarding the car, well it is compleatly bastardized by previous owner. Original interior was swaped for some ****ty seats and rear panels from 928, exterior also received some horror. 930 slant nose full fiberglass kit was installed, additional early carrera fiberglass wing was also installed. So I'm gathering all the parts and will try to restore it to original state.
I dont know much about the history of this Porsche, but it stood unused in Sweden for 10 years, and additionally 1 year in Lithuania in PO garage.

I've bought it for mere ~8000usd

Here's a link to a local forum where I'm putting all progress pictures.

As for oldest car, well in Lithuania is similar understanding of the car value like in Russia. If you have a Porsche, then it must be new, otherwise - it's junk So there arent many people who understand classic cars.

will you pay his shipping to Lithuania?

[ViR2]

Shipping is not an issue I'm buying mostly everything from pelican and shipping is cheap, only 150usd for ~20kg.

I've also decided not to reinvent the bike and try to save something and I've ordered everything from pelican instead.

Thank you guys for your help

[Laneco]

I remember this car from another post. I'm very impressed that you have chosen to restore this car to its former beauty. This is a big project, but you are going to have a beautiful car and the oldest 911 in your country.

Best of luck with your project!
