Install
Installation is performed in a similar way in the reverse order. Pay attention to the following points:
–  Check if the crankshaft is on TDC for cylinder 1.
   
l  Depending on the version, interlock the crankshaft toothed belt sprocket with the crankshaft arrester -T10050- or crankshaft arrester -T10100- on TDC for cylinder 1.
Version of the crankshaft toothed belt sprocket:
A = original version of toothed belt sprocket with circular tooth flanks, rectangular marking for TDC at tooth in 12 o'clock position - use crankshaft arrester -T10050-
B = new version of toothed belt sprocket with eliptical tooth flank, triangular marking for TDC at tooth opening in 1 o'clock position - use crankshaft arrester -T10100-
  Note
t  Markings on the toothed belt sprocket and on the crankshaft arrester must be in line with each other -arrow-. The stud on the crankshaft arrester must engage into the hole in the sealing flange.
t  The crankshaft arrester can only be fitted onto the toothed belt sprocket from the front side of the serration.
  Note
t  Ensure that the used bearing shells of the camshaft are not mixed up (pay attention to marking).
t  When installing the camshaft pay attention to a correct fit of the retaining lugs of the bearing shells in the bearing caps and cylinder head.

–  Oil contact surfaces of camshaft.
–  Insert camshaft into the TDC for cylinder 1:
l  The cams for cylinder 1 on the camshaft must point upwards -arrows-.
  S15-0373
–  Then tighten bearing caps -2- and -4- alternately and crosswise.
  S15-0375
–  Apply sealant -D 454 300 A2- thinly and uniformly to the outer bearing caps onto the surfaces -1-.
  Note
Make sure no sealant penetrates into the slots -arrows- as well as onto the other surfaces.
  S15-0301
–  Install and tighten bearing caps -1-, -3- and -5-.
l  Bearing cap -5- must fit flush with the outer edge of the cylinder head as this may otherwise cause leaks on the tandem pump.
  S15-0375
–  Insert valve-lever shafts. At the same time pay attention to the markings -arrows- when removing.
–  First tighten the inner -2- and then the outer screws -1- in several stages.
–  Install gasket ring for camshaft, hub and camshaft sprocket → Anchor.
–  Lock hub of camshaft with locking pin -3359-.
–  install (set the timing) → Chapter.
–  Install tandem pump → Chapter.
–  If the valve-lever shafts or ball pins were replaced, the unit injectors must be adjusted → Chapter.
–  Install cylinder head cover → Chapter.
  Note
t  After installing the camshaft, the engine must not be started for about 30 minutes. The hydraulic bucket tappets must settle (otherwise valves would strike the pistons).
t  After carrying out work on the valve gear, carefully crank engine at least 2 revolutions to ensure that no valve touches the piston when the engine is started.
