PROBLEM
The existing 5P-9436 Plugs in dealer parts stock could have been manufactured with the incorrect Stainless Steel material. If a plug was manufactured with the incorrect type of Stainless Steel and it is put in to service on a Marine engine application where the plug is exposed to seawater, such as a seawater cooling system, then the plug will corrode and possibly fail. Caterpillar has purged the parts system and replenished with known good parts.
ACTION REQUIRED
Remove all 5P-9436 Plugs from dealer parts stock inventory. Replenish with new parts from Caterpillar.
SERVICE CLAIM ALLOWANCES
Submit one claim for all parts removed from dealer parts stock.
