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

(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.
