[bay rhapsody]

I own a 38 Open with Cummins 450's. The engine installation has the front of the engines very close to the forward bulkhead. With the belt guards in place inspection of the belts is difficult and replacement would seem almost impossible. Can anyone shed some light on when it does come time for replacement this is best accomplished?
I have attempted to remove the guards for a clearer view of the belts but I haven't suceeded yet.
