If its anything like the 300's and 500's all you have to do is pull the rear cover off (500's) and pull the right cover off (300's).

It involves replacing the Primary drive gear, and the secondary gear on the rear of the manual clutch basket. IIRC Turner makes one for the 450's.

are there any type of special puller tools involved to to the job?

depends.

The centrifugal clutch is sometimes a bugger to get off the crankshaft. I lightly tapped mine off with a brass drift. You'll also have to have a pretty powerful impact wrench to wind the locknuts off that hold the clutches on (centrifugal and manual).

Unless you have one made, you have to drill out the rivets on the clutch basket and rivet the new clutch gear on, as well as have the primary gear machined out.

If you buy one you'll get a new primary and a new clutch basket ready to go.

No you do not have to split the case. The #1 used GR on a 450 installs through the front clutch cover(not the rear). It consists of a trx 300 clutch basket gear and the small drive gear. These can be bought new from many places-for example a Mcdonald ATV parts dealer,E-bay or from a used 300 bike these are a few I know of for sure.
