Recommendations For A Cummins Air Commpressor Wrench

[k98kollector]

What is the wrench that you have found to work best for Cummins air compressor bolts? The engine is an inline six cylinder. How good are the Snap ON M1321 or M1328A wrenches? Which one of those work best or is there another wrench better?

8.3 or 5.9? Most 8.3's you dont really need special wrenches to get the air compressor off.

If you are talking about that god awful design where they use 4 bolts then I have only had to change out one and I have the Mac s wrench for it. But from what I have heard from people it is advisable to have all the ones they make if you plan on doing a lot of them

It is that God awful 4 bolt compressor of which you speak SDGUY55. It is on a Cummins ISM 11. That bottom inside bolt is the bad one to get to. The power steering gear is in the way of that bolt.
