Combines MF9690 Cummins 8 9 vs Gleaner R72 Cummins M 11

Reason for the 'new' 8.9 liter in the MF and keeping the M11 in the Gleaner is that the M11 is one of the big reasons for getting the R72_R75. The M11 could not be used in the 9790 MF because it does not meet the most recent emission standards. The M11 can still be used in the Gleaner because it is 'grandfathered' in, if you will, because the Gleaner class 7 was in production with the M11 before the new standards. The MF is new to class 7 so they had to use the new Cummins that could meet emissions standards. The front axle, final drives, and transmission are common between the Gleaner and MF, and the rear axle is common between the two as well.

Interesting to know about the "grandfather clause"; - I didn't know it pertained to emmissions standards. In this case, will Gleaner eventually have to depart from the M11, or will they be able to use it indefinitely as long as this engine is availableIJ

I think they can use the M11 as long as it is available from Cummins and as long as it is used only in the Gleaner transverse rotary chassis. Any radical departures from that design would not be able to use the M11 I am led to believe. It is interesting if you get around a later model R72, the M11 has an identification tag_label on the rear block of the motor, just above bell housing attachment to block, which states that the M11 has been exempted from certain emissions standards in this application.

Interesting that they brag about the enviornmental accomplishments of the M11 http:__www.tougheststandards.cummins.com_tshome_misc_epa.jsp
