DISASSEMBLY
Identify MLA(Mechanical Lash Adjuster), valves and valve springs as they are removed so that each item can be
reinstalled in its original position.
1. Remove MLA(Mechanical Lash Adjuster)s(A).
2.Remove valves.
(1) Using SST(09222- 3K000, 09222 - 3C300), compress the valve spring and remove retainer lock.
(2)Remove the spring retainer.
(3) Remove the valve spring.
(4) Remove the valve.

REASSEMBLY
a.Thoroughly clean all parts to be assembled.
b. Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
c. Replace oil seals with new ones.
1. Install valves.
(1) Using SST(09222- 22001), push in a new valve stem seal with applying engine oil.
a.Do not reuse old valve stem seals.
Incorrect installation of the seal could result in oil leakage past the valve guides.
b. Reassemble the valve stem seals
(2) After applying engine oil on the outer surface of each valve stem, insert the valve in the valve guide.
Install the valve, valve spring and spring retainer.
When installing valve springs, the side coated with enamel should face toward the valve spring retainer
(3) Using the SST(09222 - 3K000, 09222 - 3C300), compress the springs and install the retainer locks. After
installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring
compressor.

(4)Lightly tap the end of each valve stem two or three times with the wooden handle of a hammer to ensure
proper seating of the valve and retainer lock.
2. Install MLAs with engine oil applied on its surface.
Check that the MLA rotates smoothly by hand.
MLA should be reinstalled in its original position.
