PB 270 with a MB421LA Help

Hey guys im new here. My wife and I joined a different snowmobile club which is just starting out ( aka low funds ). Well we had a meet and greet and being a diesel guy I opted to help out with the groomer maintenance. I am trying to get the club to ok Pop tests on the injectors. There seems to be some irregularity between cylinders.

What im trying to find is a mechanics manual for a MB421LA. Any help would be appreciated.
