Need someone familiar with Magnuson Nose drive and pulley

The nose on my GP started leaking and makes a weird clicking noise when idle. I bought a Magnuson nose drive to replace the stock nose drive on my 2001 GTP (85,000 miles)

The magnuson nose drive and 3.4 pulley are keyed, I can’t run a 3.4 pulley since I don’t have the mods to support it. I’m pickling up a 3.8 pulley from pulley boys to exchange the one that's currently on the Magnuson drive and eventually would like to try the 3.4

Question: Since the nose and pulley are keyed, do I need a pulley removal tool to change the pulleys?

Thanks!

No....

As far as I remember reading the Magnuson nose drive is designed for quick changeovers (like a modular pulley system) so I'd say you won't need a pulley removal tool. If it's keyed, you should be able to just swap, no press tool required.

That is the only reason to use a Magnuson snout, otherwise a waste of money since all it is just a redone Eaton M90 Gen 3 snout with the exception of the keyed shaft and pulley. You can install a new snout seal, snout bearings, gasket and coupler on the stock snout for half the cost of a Magnuson nose drive.

Did this Magnuson nose drive kit come with a new coupler?

Awesome, I was going to order a pulley removing tool but now I'll keep the magnuson.

The drive did come with a new coupler, however, I picked up a new coupler from zzperformance since I read the one they sell is suposed to be better. The Magnuson kit even came with a new supercharger gasket.

Thanks!!!
