Good day to everyone, I'm hoping someone can steer me in the starboard direction for this quandry. I'm putting new rings on my AQ120B (spec'd at .5mm over) and am finding that there are two different sets of Volvo rings available. I'm not sure which one to choose since I don't see any of the identifying information on the engine block, but maybe I'm not looking in the right place? They are:
Ring set .5OD 275338 - AQ120B excl USA MO-85861750/XXXX. AQ120B USA MO-85885204/XXXX-.
Ring Set .5OD 275341 - AQ120B excl USA MO85861751/XXXX-. AQ120B USA MO85885205/XXXX-.
I can't find any information on the differences presented by the "MO" numbers, but want to make sure I get the right set. Anyone have any ideas?
Thanks!
