Hey all, new to the forum and working on my 2009 700 Rhino. I am swapping in a Grizzly engine and by all internet accounts this should be pretty straightforward. I have noticed the secondary sheave on the Rhino has a fan and the Grizzly does not. Will it be a big deal to run without the fan or do I need to split the case in order to swap the shaft for the longer one from the Rhino? Thanks, Andy.
