12) Remove the connecting rod screws (24).

 Connecting rods are marked 1 to 

3 for identification. Do not twist connecting rod 

halves or interchange them. When reassembling, 

the connecting rod must be fitted in their exact 

original position on the crankshaft journals.

13)  Push connecting rod halves together with the 

crosshead as far as possible into the crosshead guide. 

Take out bearing cover (14/14A) and push out crank-

shaft taking particular care that the con rod doesn’t 

get bent.  Check surfaces on the connecting rods (24), 

crankshaft (22) and crossheads (25).  Check the sur-

faces of the crosshead guides in the crankcase for any 

unevenness. 

15) Mount bearing cover (14A) and tighten screws (17) to 64 Ft-lbs. Adjust axial play (clearance) on the 

crankshaft to minimum 0.1 mm / max. 0.15 mm using shims (21A/21B). The shaft should turn easily with little 

clearance. Connecting rod must sit exactly in the middle of each crank pin. Fit the bearing cover (14) and 

tighten the screws (17) at 64 Ft-lbs.  Seal (32A) must always be installed so that the seal lip on the inside 

diameter faces the oil. Possible axial float of the seal adaptor (33) to be compensated with shims (33C).

Mount cooling plate (K1) and gear cover (K3) with their respective seals (K2). When assembling the cooling 

circuit line, make sure that the oil cooler connection (K7) is always joined to the 

upper

 connection (K3) of the 

gear cover.

14)  Reassemble in reverse order. Thread the 

long end of the crankshaft together with the inner 

bearing rings into the crankcase; then mount 

outer bearing ring (20) and spacer ring (22A).  

Mount connecting rod halves in their exact origi

-

nal position and tighten at 37 Ft-lbs.

 Connecting rods must be able to 

move slightly sideways on the stroke journals.
