About World Wide Parts World Wide Parts & Equipment, Inc. was established in February 1995. For the last 20 years we have been selling primarily new diesel engine parts for Caterpillar, Detroit Cummins, etc. to the oilfield equipment and truck industry. Some of our largest customers previously were OEM — Caterpillar only customers for years. Since their introduction to IPD engine parts, several of the major drilling companies, such as Rowan Companies, Pride International Ensign, Pioneer, Columbia and Nabors Drilling have converted from OEM — Caterpillar to IPD and FP Diesel parts. This conversion has saved these companies significant amounts of time and money, while improving service and productivity. World Wide Parts & Equipment, Inc. maintains a two-acre facility in Houston with 23,000 square feet. We can sell parts for your own rebuilding needs.
