REMOVAL AND INSTALLATION

Removal steps >>A<< 1. Water joint 2. Bolt 3. Knock bush >>C<< 4. No.1 camshaft cap >>C<< 5. No.2 camshaft cap >>C<< 6. No.3 camshaft cap >>C<< 7. No.4 camshaft cap >>C<< 8. INo.5 camshaft cap 9. Camshaft >>B<< 10. Lifter shim 11. Valve lifter

1.To install the water joint first tighten it to the specified torque, then give an additional torque so that it may be angled as shown. The additional tightening torque should not exceed 7 N.m above the specified torque.

1.Select a proper thickness lifter shim that allows the valve clearance to be kept at the specified standard value and install it in the following manner: Attach an arbitrarily selected lifter shim to the valve lifter. Install the camshaft in the cylinder head, and attach the camshaft caps. Using a filler gauge, measure the valve clearance of the valves on which the respective cam lobes are located within the range A shown in the illustration. Record the readings. Standard value: Intake: 0.2 Exhaust: 0.3 caution The correct measurement can be achieved only when using a feeler gauge which feels somewhat heavy to insert. No accurate measurement can be expected with a loose filler gauge. To measure the valve clearance of the remaining valve, turn the camshaft, or remove it and reinstall, in a position where their cam lobes are in the range A. Then, measure the valve clearance in the same manner as above. Based on the readings recorded, select an appropriate lifter shim for achieving a valve clearance true to the specified standard value, and replace the lifter shim with it. Lifter shim thickness 2.250 - 3.150 mm Available in 37 size at steps of every 0.025 mm Stamped size mark "2275" denotes a thickness of 2.275 mm Shim thickness necessary for valve clearance adjustment : Thickness of removed shim + (gauge thickness - specified standard value)

1.Install the camshaft caps with their front marks directed forward, and tighten the bolts to the specified torques.
