Overview – BLOCK, LONG 6C (OBSOLETE)-MTO DR5031RX
The Cummins BLOCK, LONG 6C (OBSOLETE)-MTO DR5031RX is specified for Cummins 6-cylinder engine block and major-overhaul programs and is supplied to the original dimensional and material standard.
Parts Characteristics
A 6-cylinder long engine block (exchange unit) – the structural core carrying the crank, cam and main bores around which a complete overhaul is built. Its bore condition and main alignment set the baseline for the whole engine, so a sound block returns the unit to spec at a fraction of a complete new-engine cost.
Applicable Models & Applications
Used to service Cummins 6-cylinder engines. Confirm the block matches the 6C family and your arrangement before ordering – long blocks differ in front-end, mount and accessory provisions.
Maintenance & Replacement
Rebuild around a verified block rather than line-boring a tired one when the bores are out of limit. A fresh block with cleaned, tested components returns the engine to specification for far less than a complete new unit.
Never fit a block without addressing the supporting systems. The most common reason a rebuilt engine fails early is contaminated lubrication or a cooling fault carried over – fix those as part of the job.
Confirm the block is a genuine exchange unit and return the old one promptly if it is. The core charge only comes back on a serviceable return, and a missed return turns a good saving into a full-price purchase.
Record the block serial and the components fitted to it. A documented rebuild is easier to warranty and far easier to service correctly the next time it comes apart.
Price Reference (USD)
The BLOCK, LONG 6C (OBSOLETE)-MTO DR5031RX generally falls in the USD 3000-7000 bracket, with expedited freight quoted separately.
Value & Service
