Preliminary to Reconditioning
Method of Handling:
To facilitate spark plug handling with minimum possible damages (to and from the engines and during
reconditioning process, ) a sheet metal or wooden holding tray of suitable size to accommodate from two to four
sets of sparks should be used.
If a spark plug should accidentally be dropped at any time, it should be identified with a tag for special inspection
and electric testing regardless of the fact that no damage is apparent by visual inspection.
Typical metal handling tray. Plugs can be identified by
spacing or upending,. Wooden trays can be made
locally using 8" x 8 x 2" wooden blocks. Drill 3/4" dia.
