When assembling the upper and lower crankcase sections, be certain to properly align the surfaces (arrows) where the oil pump seals to the crankcase.
Proceed as follows:
Tighten the M12 nuts of the lower crankcase half to 10 N-m (7.2 ft. lbs.). Use a straight edge to check the alignment of the oil pump sealing surface. If adjustment is required, use a plastic hammer and carefully tap the lower crankcase section in the direction needed to obtain perfect alignment.
Tighten the M12 nuts in the following sequence:
1st step 20 N-m (14 ft. lbs.) 2nd step 50 N-m (36 ft. lbs.) 3rd step 90 N-m (65 ft. lbs.)
Re-check the oil pump sealing surface alignment. Tighten the remaining bolts and nuts to:
M10 - 1st step 20 N-m (14 ft. lbs.) 2nd step 50 N-m (36 ft. lbs.) M8 - 20 N-m (14 ft. lbs.) M6 - 10 N-m (7.2 ft. lbs.)
