Fitting piston and connecting rod
1. Check that the inside of the cylinder block is
clean.
2. Remove the cover from the big-end bearing
journal and lubricate the journal.
3. Turn the piston rings so that the ring gaps are
evenly distributed round the piston.
4. Fit assembly tool 99 241 instead of the loose
ring in the liner.
5. Carefully insert the connecting rod with pis-
tonsothatthearrowmarkonthepiston
points forward.
6. Lubricate piston ring compressor 98 323 and
fit it round the piston.
7. Press the piston down into the cylinder past
the assembly tool.
8. Remove the assembly tool and press in the
loose ring. Take care to press the ring straight
down so that it does not enter at an angle or
become skewed.
9. Place the big-end bearing halves in the caps
and lubricate the bearing surfaces. Fit the
caps. Check that connecting rod and cap have
the same marking and that they are opposite
each other.
10. Lubricate the bolts, fit them and tighten alter-
nately in two stages. Stage 1: 50 Nm,
stage 2: 110 Nm.
