BCBC IS-63 Engine Oil Pump Intermediate Shaft

Engine oil pump shaft for classic Mopar applications

The Melling IS-63 engine oil pump intermediate shaft is a standard replacement part made in the USA for a wide range of Chrysler, Dodge, and Plymouth applications. It is built to replace a worn shaft during an oil pump service and help restore proper pump drive engagement.

• Stress proof steel construction for added shaft strength
• Standard replacement design for service work
• Made in the USA
• Fits a broad range of classic Chrysler, Dodge, and Plymouth engines

Built around serviceable shaft dimensions

This intermediate shaft measures 7.940 inches in length and 0.485 inch in diameter, with stress proof steel used for the shaft material. Those specifications matter in oil pump service because the shaft transfers drive load to the pump and must resist fatigue, cracking, and twisting over time. The IS-63 is a practical choice for restoring the oil pump drive system on vehicles such as the Dodge Charger, Plymouth Fury, and Chrysler Newport. Part number IS-63 is also referenced by several interchange numbers, including 601-1437 and 224-6174, for the same application.

What this part helps address

• Worn or fatigued oil pump drive shafts
• Cracking in the original shaft
• Twisting damage from repeated load cycles
• Poor oil pump drive transfer during service replacement
• Need to complete a new oil pump installation with a fresh shaft

Installation notes and quality

Install this shaft as part of an oil pump replacement and verify proper engagement with the pump drive components before final assembly. The fitment list includes stock applications with bronze bushing notes across many classic Chrysler, Dodge, and Plymouth models, so confirm the exact engine setup against the vehicle application before installation. Melling recommends replacing the shaft whenever a new oil pump is installed, and the IS-63 is part of its line of replacement shafts for domestic and import pump applications.
