of the tensioner cylinder are aligned.
C a u t i o n If the compression speed is too fast, the rod may
become damaged, so be sure to carry out this opera-
tion slowly.
(4) Once the holes are aligned, insert the set pin.
NOTE
When replacing the auto tensioner a new part, the
pin will be in the auto tensioner.
(5) Install the auto tensioner to the engine.

shaft sprocket and oil pump
(2) After aligning the timing mark on the oil pump sprocket,
remove the cylinder block plug and insert a Phillips screw-
driver with a diameter of 8 mm in.), and check to
be sure that the screwdriver goes in 60 mm (2.36 in .)
