(g) As sequences shown in the diagram, loosen camshaft

bearing cover bolts on intake camshaft at several times

and remove the bearing cover at the same time.

(h) Hold timing chain with hands and then remove the

camshaft.

(i) As shown in the diagram, tie up the chain with bandage.

Note: be careful not to let anything fall into the

timing chain hood.

(j) Remove valve lifter.

(k) Measure the thickness of this valve lifter with

Hints:

New valve tappet chosen should be near the value cal-

culated as much as possible.

The thickness of valve tappet is from 5.06mm to 5.74mm,

and there is one specification every 0.02mm, therefore

there are totally 35 different dimensions to chose.

(m) As shown in the diagram, align alignment mark with tim-

ing mark on camshaft timing sprocket, and install timing

chain on the timing sprocket.
