2.7.2. Checks on camshaft axial clearance
(1)、When the axial spacing is measured
with a clipper to be larger than the
benchmark value, the camshaft is to be
replaced. The air inlet camshaft axial
clearance is 0.1～0.170mm。The air
exhaust camshaft axial spacing is 0.1 ～
0.173mm。Limits for operation：0.18mm
2.7.3. Checks on
clearance
(1). Put camshaft into cylinder head
(2). Make sure the front mark on bearing
cover and shaft number is ok, and then
tighten bolt.
(3). Fix air inlet camshaft, and then
measure the clearance with dial indicator.
Attention: measure 4 points around gear
² use a special tool to rotate air inlet
camshaft.
²under the condition that the mark on
drive-gear match the mark on driven-gear
