Special point

check with a ruler prior to assembly that the supports

housing (Fig. 13). If they are not, adjust the support(s)
until they are correctly aligned. Tighten the screws to:
- (4) 240 - 320 Nm (Loctite 270 or equivalent),
- (6) 240 - 320 Nm.
Check correct alignment after tightening.
26. Screw a guide stud onto each rear face of the
frame (Fig. 12).
27. With the help of an operator, assemble the front
frame onto the engine. Take out the guide studs.
