Hi Chris,
I've got a panther 27 and when I had it fitted at woodbridge they added a spare pump belt but tie wrapped it back out of the way for an easier fit incase the original one broke.
I'm not sure if your machine is laid out the same as mine but watching and talking to the engineer when mine was fitted you might have to remove the heat excahgers for access. Then unbolt the engine and slide it forward, disconnect the blower drive shaft (at the rubber gator) then you could fit the new belt.
Straight forward enough but I have watched it being done so easy for me to say.
If you're confident doing it yourself then go for it, if not pop to woodbridge and they'll do it for you. You can always watch so you know how to do it again in the future!
Hope this helps.
All the best,
Jason.
