bolt with a hardened washer into the rocker arm bolt hole.
Caution: Compressed valve springs have high tension against the valve spring
compressor. Valve springs that are not properly compressed by or released
from the valve spring compressor can be ejected from the valve spring compressor
with intense force. Use care when compressing or releasing the valve spring
with the valve spring compressor and when removing or installing the valve
stem keys. Failing to use care may cause personal injury.
- Use the J 5892-D
in
order to compress the valve spring.
9.1. | Hook the slotted end of J 5892-D

when there is not enough clearance
to use J 5892-D
.
- Remove the valve keys.
- Carefully release the spring tension.

Installation Procedure
Important: The L43 Engine uses a unique valve spring seat and seal combination
unit. Under no circumstances should this seal and seat unit be replaced with
a different type of seal. Use care to ensure that the valve stem seal and
spring seat are not damaged during installation. Do not use excessive force
or a hammer to install the seal on the guide. The seal will go on if straight
and properly lubricated using hand pressure only.
- Lubricate the outside of the valve guide and the valve seal with clean
engine oil.
- Using the J 38820
install the valve spring seat and seal unit onto the guide. Push
and twist the valve seal into position on the valve guide until the
spring seat flange is flush with the cylinder head surface.
- Set the valve spring in place.
- Set the valve spring cap in place.
Caution: Compressed valve springs have high tension against the valve spring
compressor. Valve springs that are not properly compressed by or released
from the valve spring compressor can be ejected from the valve spring compressor
with intense force. Use care when compressing or releasing the valve spring
with the valve spring compressor and when removing or installing the valve
stem keys. Failing to use care may cause personal injury.
- Compress the valve spring
with the J 5892-D
.
Notice: Completely engage the J 38606 jaws on the valve spring.
The J 38606 may slip off and scratch the valve spring. Replace the valve
spring if the valve spring becomes scratch.
- Use the J 38606
if the clearance does not permit the
use of the J 5892-D
.
- Install the valve keys.
Use grease in order to hold the valve keys in place.
- Carefully release the valve spring pressure making sure the valve
stem keys stay in place.
Notice: The valve stem keys must correctly seat in the valve spring cap. Engine
damage may occur by not installing properly.
- Remove the J 5892-D
or
the J 38606
