Original 12 volt crank pulley diameter??
I bought this degree sand seal pulley many moons ago, and i suspect its a power pulley, but i have no idea. I can't remember out of the many things i
ordered in my parts inventory...
How wide is the stock pulley?
I have a steel 6 volt stock crank pulley, will that be the same diameter as the 12 volt?
It won't fit though with my sand seal, but just something for me to play with none the less.
Thanks guys!
Christopher Leete.

Hi Chris...
most sand seals are machined to fit into the case,,,
and use a special pulley...
I see now You can buy a sand seal that fits into the case and a special pulley is again used....
so, NO seal to be used with a VW pulley....
the VW pulley is used with the oil slinger..
cheers
LEE
PS: I don't like or recommend power pulleys... LEE
PSS; many NEW alloy pulleys now need shims to make them fit????

Thanks Lee!
Yea i got the sand seal that you tap in. Bloody genius!, and sooo easy. i got the proper alloy pulley for it and the shims. I fitted it without the shims and when torqued up, the crank locked up
(eek!) i couldn't turn by hand...
I just wanted to measure up the crank pulley to make sure i didn't grab a sand seal pulley when i bought it ages ago... Cause like you and alot of
wise dubbers i have heard, no one seems to approve of them, and rightly so. The vw engineers had it right the first time and don't want to break away
from that.
If its a power pulley it can be someone elses problem

yes
NO......a 6 volt pulley is smaller and also has a different offset to a 12 volt pulley.
A 1300 12volt twinport pulley is the same as a 6volt pulley in diameter but has the correct offset (same as a 12v)
I use the 1300 TP pulley on the street as you can rev past 7000rpm without throwing a belt due to the slightly smaller size.
