Removal
1. Remove the right engine guard from the bottom and the right mudguard.
2. Remove the valve cover.
3. Set the piston of cylinder No.1 to TDC in the following order:
a) Turn the crankshaft pulley clockwise and align the front cover indicator with the yellow stamped mark on the crankshaft pulley.
For more information, see the website NISSANBOOK
b) At the same time, make sure that the alignment marks on the camshaft sprockets are aligned with the colored links of the timing chain.
Otherwise, turn the crankshaft pulley one more revolution and align the marks.
4. Remove the distributor.
5. Remove the timing chain tensioner.
While holding the chain tensioner down with a rag, loosen the two mounting nuts one by one and remove the tensioner.
Caution: Be careful as the tensioner is spring loaded and may pop out and oil may spill out.
6. Remove the camshaft sprockets.
Secure the hexagonal portion of the camshaft with a wrench, loosen the bolt and remove the sprocket.
Caution: Do not secure the camshaft in any location other than the hexagonal portion, and do not use chain tension when loosening the bolt.
Note: Because the position of the crankshaft sprocket does not change in relation to the timing chain when the front cover is attached, there is no need to maintain chain tension.
7. Remove the camshaft brackets.
Before removing, mark the brackets to help you determine where they will be installed.
Loosen the mounting bolts in several stages in the order shown in the figure.
8. Remove the rocker arms, adjusting washers, rocker arm guides and hydraulic valve lifters.
Attention:
Check the installation locations of the parts, mark them if necessary and arrange the parts in order to avoid confusion.
Do not disassemble the valve rocker arms.
Do not disassemble the hydraulic valve lifters.
Hydraulic tappets are stored in a vertical position. If you need to store them for a long time, immerse them in fresh engine oil.
