Clutch ID?
Everybody,
I have a '69 911T that someone put a 1970 911T motor in. I'm planning on doing a bunch of work on the car to get it up to snuff in a couple of weeks, and while I have the motor out I need to change the very worn out clutch. I know the clutch system changed between 1969 and 1970. I am pretty sure the car has its original 901 5sp transmission. Is there any way to tell if I have the early 65-69 clutch vs. the 70-73 system with the engine still in the car? If you were putting a '70 engine in a '69 body and tranny, would you need to use the '69 flywheel? I really want to have the right parts waiting for me so I can make the most of my short repair window. Sadly, the car is near Houston, TX; I'm in Pensacola, FL; and I live in the Washington DC metro area. I will have two short weeks with my car to make it good enough to drive from Texas to Virginia. Thanks!

If the transaxle is a 1969 901, then you have the 215mm push clutch. The 225mm pull clutch from the 1970/1971 type 911 transaxle needs a different pressure plate, flywheel, and release mechanism. Post pictures.

Where is the part # on the tranny? Is getting to it a dirty job?
(I ask because I'm having to talk my dad through all my part # gathering.) Just to confirm, if it does have a 69 tranny #, then it must have the 215mm clutch, right? -Dan |

Yes you need the clutch for the trans, the flywheel will have a recessed clutch area with the ring gear part of the flywheel. Typically the 65 to 69 encompasses your need.

Grady Clay mentioned that the earlier 901 cases have a shorter boss for the throwout bearing release fork than is needed for the 911 pull clutch. The only way to attach the later fork pivot would be to weld on new material and tap a hole for the pivot.
So, yes, a 1969 901 has the push clutch.

Sadly, I can't get any pictures. The car is about 700 miles away at the moment.
Where is the # usually stamped on the transaxle? Is it accessible without a lift? I promise, lots of pictures once work begins.

On a type 911, which would be a 1970 or 1971 transaxle, it is here:

Yeah, that was after the surprise gearbox rebuild. The mechanic was changing the lubricant and found a chunk of a gear tooth on the drain plug magnet. Engine and gearbox came out, opened the trans, found fourth gear had half a tooth missing, which was why it felt fine. He replaced the fourth gear set and the second gear synchro and slider assembly. The other synchro bands were flipped. All the (mega-expensive and NLA) bearings and stuff were great, so it was not all bad, and I found out which gears I have. You do not want to break anything on a type 911 transaxle. They were only made for 2 years, 40 years ago.
