Hi all, I'm in need of a new pulley after the bolt & washers managed to work their way out of my Novi 1200 & are on the road somewhere in France. I'm looking at the Griptec pulley & green belt as I've heard they are better than the standard SOS ones. I've looked at LHT performance but they don't ship to the UK. Any suggestions as to where to get a 3.2" one for my Novi 1200 charger, along with the belt & the seller does international shipping? Also, based upon this video from LHT, it appears that you can fit the new pulley with the charger in place - is this correct?

 

I got mine directly from griptec, only took a few days to arrive here in Sweden.
This is the one https://www.zpegriptec.com/3-20-zpe-...ulley-hub-kit/
Seems kind of hard to get the green belts here in europe as well so got them from Rockauto

 

You can install it with blower still in place but I would recommend removing it for a lot better access.
I had to remove factory tensioner and one of the allen head bolts on the front of the head to get enough clearance when removing old pulley.
Also no way to get a room for a torque wrench with a regular socket on when installing the pulley bolt again.

 

Am I right in thinking that the Griptec pulley has no centre bolt unlike the SOS pulley as you can see in my picture?

What actually holds the hub of the pulley on to the shaft of the charger?

It's press fitted and bolted down just like the sos pulley.
Here is my crow foot setup to torque it down in place.

 

One question on the belt that you recommended. It appears to be 2" shorter than the standard belt used by SOS for the 3.2" pulley. What impact does this have, or does it simply mean less adjusting / tensioning?

 

Oh sorry I forgot to mention I'm using the Comptech gen1 with the SOS novi 1200 conversion kit.
Don't think you could use this shorter belt if you got the standard SOS system.

 

Do you know if you can get the green belts in the correct length (39.5") that I need, as in standard size for SOS system?

 

Not sure, looks like the closest is K060393HD at 39.3"
