BCBC K-58D Engine Oil Pump Repair Kit

Engine Oil Pump Repair Kit

Melling K-58D is a specific-fit engine oil pump repair kit for rebuilding a single oil pump assembly. It is a practical choice when you want to reuse the original oil pump casting or front timing cover instead of replacing the entire pump.

Key Features

• Specific-fit repair kit for rebuilding one oil pump assembly
• Powdered metal drive gear for durable internal operation
• 9-tooth drive gear configuration
• High-temp fiber paper gasket material for sealing performance
• 4-hole gasket layout for the correct pump interface

Detailed Description

Melling K-58D oil pump repair kit is built for rebuild work where the original pump housing or front timing cover is being retained. The kit is centered around the internal service parts needed to restore pump function, including a powdered metal drive gear, a 9-tooth gear design, and a high-temp fiber paper gasket. This part number, K-58D, is a specific application kit rather than a universal service item, so fitment should be matched carefully to the intended engine oil pump assembly. It cross-references Monroe Shocks & Struts (e.g., 51-26, 224-5126) for the same application.

What It Is Used For

• Restoring oil pump operation during engine rebuild work
• Replacing worn internal pump components
• Reusing the original oil pump casting or front timing cover
• Addressing sealing issues at the pump gasket interface
• Correcting drive gear wear in the pump assembly

Installation Notes and Tips

Verify the pump design and application before installation, since K-58D is a specific-fit kit. Clean all mating surfaces thoroughly, inspect the original casting or timing cover for wear, and confirm the gear count and gasket pattern match the existing assembly. For best results, follow the service procedure for the engine oil pump being rebuilt.

Quality Assurance

Melling supplies repair kits with the parts needed for a quality oil pump rebuild. The brand also notes that replacing the complete oil pump is often recommended, while this kit is used when the original casting or front timing cover will be reused.
