Clutch/Gearbox interchange - throw-out bearing
68beetle - December 2nd, 2005 at 10:32 AM

Hi,

Looking at swapping the old 1100/1600 motor out of the beetle with a newer 1600. The old motor was an upgraded 6 volt and had a 6 volt starter running off the 12 volt system.

Anyway I know I'm going to have to give the bellhousing a bit more clearance to fit the newer flywheel and swap the starter motor and bushing to take a 12 volt starter.

My question is about the throw out bearing and clutch interchange.

Below is a copy of the throw-out bearing in the gearbox. I was told by the past owner that the gearbox had been swapped.

Also following are copies of the old clutch and new clutch.

Can anyone tell me what I can do to make the new clutch fit? Is it as easy as swapping the throw-out bearing and removing the sleeve the existing one runs on?

Thanks in advance.

Picture of old clutch. I thought these were meant to have a ring in the middle??

Picture of new clucth. From my understanding these can't be used with the throw-out bearing I currently have?

Hi

The picture is a bit small or getting old, but it looks like you have a later 12 volt box already. Does the thrust race slide on a thin sheet steel sleeve? If it does you can use the the pressure plate with the ring, just remove the ring 1st, there should be a clip holding it in place on the other side.

Weird how things happen but I just got an email off the guy who used to own it with some more info. I didn't even ask him for it - he just found some parts in the shed and decided to give me a run-down.

The gearbox is out of a 73 beetle so it sounds like it should be 12 volt already. Flywheel off the old engine is definitely 6 volt so that might be why so many teeth are ripped away? The throwout bearing does run on a thin metal sleeve.

To quote:

"So I obtained a trans from a 1973 Beetle. This was OK, but ...
fitting required the nose cone from the old transaxle to go on the 73.
The throwout bearing, input shaft shroud and "hockey stick" link at the front (FIF - as per Muir's book) of the trans also had to be swapped off the old trans.
73 axles were longer so the axles and axle tubes from the original went in.
In 73 the wheel stud pattern was different as well, so the original brake drums etc would have gone on as well, although I don't recall actually doing that.
I found the 73 nose cone and other bits'n'pieces the other day."

So is the best way to do this to swap the throwout bearing and input shaft shroud or to remove the ring from the thrust plate? I'm building this beetle to do charity rallies so i'd like to do things the best way.
