to assembly of tappet for details; Install camshaft, do not damage camshaft surface and engine
block hole during the push-in process of camshaft and the push-in strength should be equally,
the end with thread should be on engine front cover side.
(3) Install sector plate, tightening torque of bolts should be 35±10Nm, seal up the bolts with
lacquer.
(4) Install gaskets, flange, washers and hexagon bolts on camshaft threaded end. Measure the axial
clearance of camshaft, which should be 0.1~0.29mm, if the clearance is too small, check
whether there is burr between camshaft and sector plate. If fail to adjust the clearance to
required range after deburring, then the camshaft should be replaced.
(5) Rotate the crankshaft until 0 tick on timing gear is closest to camshaft, firstly install fuel
injection pump driven gear on the camshaft, and then install camshaft timing gear, make sure 0
tick of timing gear is engaged with 0 tick of fuel injection pump driven gear;
(6) After correctly installed the gears, mark 0 tick position of fuel injection pump driven gear and
crankshaft timing gear with a marking pen.
(7) After adjusting the holes, install camshaft bolts (cleaned and applied with KB277 sealant)
through flanges holes; pre-tighten camshaft timing gear fixing bolts with pneumatic impact
wrench, and pre-tighten connecting bolts between camshaft timing gear and fuel injection pump
driven gear. Tighten the bolts with torque spanner, tightening torque for M10 bolts: 85~90Nm,
tightening torque for M8 bolts: 55~60.5Nm, seal up the bolts with lacquer after tightening.
Rotate crankshaft to check whether 0 tick of each gear is normally engaged.
