6volt -> 12volt
Just pondering the idea of putting a 1600 engine into my 61.
Instead of clearancing the bellhousing, can I just change over the flywheel and clutch assembly?
Cheers
Tnate

Tnate, that will work OK. Thats what I have in the 57. But the 6V starter will eventually give trouble. As I'm also finding. The faster spin
with 12volts really gives the teeth on the starter and fly wheel hell and the higher current makes em get really hot.
I'm about to do the full change over on the 57 as its also due for a new clutch.
If it was me starting from scratch I'd go the whole hog first time.

Clearancing the bellhousing isn't that hard, I did it when I put a 1500sp in my 62. I ended up puting in a 1500 swingaxle box though for better
matching of the ratios to the engine power. It was a much better solution in the end as now I run 1500 components for the whole drive train and I can
easily bolt up a 1916 when I'm ready

i had to do this recently, clearancing the bellhousing isn't really that hard, u should drop the tranny to do it.
Remember a 6v starter will only go with a 6v/180mm flywheel and 12v with a 12v/200mm flywheel. If you are using the larger flywheel u will have to
install a conversion bushing in the tranny, which is as easy as tapping the old one out and tapping the new one in.
The 6v starter should be able to handle the 12v for quite a while, just don't run it for minutes on end. the 180mm clutch can handle the torque
of a 1600 but it is better to go to a 200 anyway if u intend to do any future upgrades.

No No no
A 6 Volt flywheel will not fit properly onto a later 12v engine as the crankshaft on the later engine has a step machined into it for the flwheel O
ring seal to sit into.
the 6 V wheel wont sit flat and not run true.
I think that there was some later model 6 volt flywheels Kombi type that did have the O ring seal in them but finding these would be very hard.
clearence the bell housing in 4 places and get a starter bushing and fit a 12 volt starter then you have the best combination.

I have two 180mm Flywheels which have the o-ring in it, they are from 1300's.
Yes you are correct about the 1200 flywheels which have that gasket with the 4 holes for the dowels.
i found that i had to clearance the 4 raised bits where the studs go as well as the bits inbetween to get the flywheel to turn freely, when i
completely bolted it up the flywheel finished the job.
