G’day, so found another Cummins engine for grader I think it had a H6 135 Cummins ( put a con rod through block . So found a Hb1 think about 175 hp ? And I have swapped the sump so pan is at front of old engine and bell housing, all fitted but! Did notice rear main seal and crank a little different. My main question is as it is a wet clutch the seal witch is a oring that seal between bell housing important. I am thinking not much oil would get up behind fly wheel and out between housing and block . My bell housing has a drain at bottom so I think not much oil is in housing. I think oil is feeded from pipe onto clutch then drains out bottom goes into a filter thing then back up and onto clutch...? Any information on motor and clutch would be great to hear . My rear main is a two piece as crank is stepped down. On old motor crank was not stepped so cover had rear main then oring to seal it all . I hope it all works and fits . Thanks mate!
