Use a strong magnet to carefully lift the bucket out of it's bore.
Be careful, as the shim often sticks to the bucket and can fall into the cylinder (if plugs removed) or oil passageway.
Do not mix the buckets. Make sure they go back into the same bore they came from.
Write down each shim's clearance and when known, each shim's number as a record for when shim thickness calculations are to be done.
When installing the cam journal caps, be sure and orient them in the proper direction.
The arrows on the journal caps have arrows that always point towards the intake.
The journal caps also have indicators for which cam they are for.
The correct indicator are those that are not scribed through.
This is the cam journal cap for the Front Intake cap.
And this is the Front Exhaust cap.
