Overview – SOCKET BIT 3400038 Series
3400038 is the CUMMINS SOCKET BIT used on Cummins diesel engine service tools and workshop applications. We can supply this line as well as the related family numbers listed below, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
3400038 is the CUMMINS service socket bit used with standard ratchet drives for the fasteners specified in the engine service procedures. The bit is hardened to the original drive specification so it engages the fastener without rounding the head, and the shank is machined to the OEM profile for a firm grip in the socket. The surface is treated against corrosion for workshop storage.
Applicable Models & Applications
This socket bit is used on CUMMINS diesel engine service work where the original 3400038 size applies, including fastener removal and installation in engine and generator applications. Confirm the drive size and the fastener profile against your socket set before ordering. The related 3400039 covers the next size in the series, and we can confirm the correct bit from the fastener you are turning.
Maintenance & Replacement
Inspect the bit before each use for a worn or chipped tip, as a rounded bit slips on the fastener and damages the head. Clean the bit and the socket drive after use, and store it in a dry tool box to prevent corrosion. Replace the bit when the corners show wear, and always use the matching size rather than forcing a smaller bit into a larger fastener.
