914 Flywheel

Does anyone know for certain whether or not a VW 2 litre van flywheel can be used in a 2 litre 914?

You could try Volkspeed in Loscoe, Derbyshire. They used to import them years ago and used to have spare engines knocking about.
Worth a try anyways.

I reckon so. The clutch is interchangeable and the diameter is the same (215)
I have one in my garage but it'll be a few weeks until I take my gearbox off so I can size them up against each other then.
You may have to re-paint your timing marks though.

the size might be right but the starter gear/teeth might be abit different, I'm not sure, just have a gut feeling about it.

Thanks for all the advice and tips. I'm a little puzzled as to why I should have to repeaint the timing marks as mine are located on the cooling fan not the flywhell.

Pelican have the part number 022-105-273A-M260 for 914 flywheel, the 022 part is a VW van code, I think

I just realised I responded to the wrong thread, should have been the one in the wanted section

The flywheels a defo different, not interchangable ie if you have a 914 you cant put a bus flywheel on and put it back in ya 914, if I read you Q correctly Dave..

The bus has 3 different sizes 210, 215 & 228, they do fit but wont work with the 901 box

Thanks you have confirmed what a Yank emailed me i.e. the van flywheel although similar doesn't match up with the 901 g/box something to do with the position of the g/box input shaft.

part number for van ends in 271 whereas the 914 ends in 273A

Just measured the bus flywheel against a 9146 flywheel (which fits the 901/914) and the OD is different plus the starter ring tooth patern is way off.

The 914/6 flywheel is different as the clutch and all parts are totally different. Part number for the 914/6 flywheel is 901-102-026-01 whereas the 914/4 is 022-105-273A. The VW Flywheel has same number of teeth(130) and uses the same starter motor.

However, it's is evident from all the replies I have, including a couple from Pelican Parts(USA), that the VW flywheel is the same in all respects except the positioning of the bearing for the the drive shaft from the 901 G/Box.

The 914-6 flywheel has a different bolt pattern but the four cylinder clutch should be interchangeable with the 6 (albeit with different part numbers).
Out of interest I will definitely take some pictures of the bus + four flywheel side by side when I get time to split engine + gearbox few weeks.
Sounds like my '2.0 bus' flywheel might be something else ..

You will notice when there alongside each other the 914 flywheel it deeper than the bus or type 4 versions, the disc is different because of the 901 box splines also the pressure plate. The 914 is unique to the Type 4 style engines, but similar/same?? as the 914/6 & early 911.

Well explained Adam, that makes sense to me now, Thanks

So, to sum up, the bus flywheel is different(as the yank said -won't match up with 901 G/Box) and the 914/6 is similar but as the teeth on the flywheel are different it too will not be suitable, in fact it is probably as difficult to locate a 914/6 flywheel as it is a 914/4.

Everything is sent to try us, lol.

Dave

PS anyone know where I might get my flywheel refaced as the groove isn't that deep?

Did you not try Volkspeed for a s/h one?

Any machine shop should be able to do it. AFAIK you have to take the same amount off the clutch plate mounting surface.
