Precision Remanufacturing Backed by Real Testing
At Turbo Kings, every Knorr-Bremse 23536774 air compressor undergoes a precision-controlled, in-house rebuild process that restores full OEM performance and verified reliability.
Manufactured by Knorr-Bremse and installed by Detroit Diesel on Series 60 EPA07 and early DD13 engines between 2008 and 2011, this compressor represents the transition between the legacy Detroit platform and the modern DD series.
The 23536774 is a two-cylinder, single-stage, water-cooled, gear-driven unit, engineered to deliver roughly 16.5 CFM at 1250 RPM. Its compact form, thermal efficiency, and balanced output made it standard equipment across Freightliner Cascadia and Western Star models of its generation.
At Turbo Kings, compressors are never “resealed” or “cleaned up.” Each unit is completely stripped, machined, and rebuilt to specification. Bores, bearings, and journals are gauged for taper or scoring; valve assemblies are refaced for proper seat alignment; and all wear components are replaced with OEM-grade Knorr parts or improved equivalents to restore precise compression balance and output stability.
All air and coolant passages are ultrasonically cleaned, a process that removes scale, carbon, and internal oil residue unreachable through conventional flushing. This ensures full thermal conductivity and unrestricted airflow — critical for long-haul and stop-start operation alike.
Once rebuilt, every compressor undergoes bench-testing under simulated engine load, verifying pressure build rate, oil carryover, leak integrity, and cut-in/cut-out stability. Each unit must meet or exceed Knorr-Bremse and Detroit Diesel OEM flow standards before serialization and packaging.
This isn’t assumed performance — it’s tested and verified right here at Turbo Kings.
What Makes a Turbo Kings Rebuild Different
Knorr-Bremse OEM Foundation – Built using original Knorr-Bremse data and specifications for Detroit Diesel applications.
In-House Flow & Pressure Testing – Simulated load testing ensures verified output and oil control before release.
Ultrasonic Cleaning Process – Air and coolant lines ultrasonically restored for optimal heat transfer and pressure balance.
Precision Machining – Decks, heads, and valve seats resurfaced to OEM tolerances for true sealing and compression.
Pre-Lubricated & Ready to Install – Shipped sealed and primed with lubricant for drop-in installation.
Warranty Confidence – Backed by a 12-month, unlimited-mileage warranty with serialized records and test data archived.
Why Fleets and Owner-Operators Trust Turbo Kings
Fleet managers, diesel rebuilders, and independent operators rely on Turbo Kings compressors because every unit is validated under real operating conditions — not just assembled and assumed ready.
Our process ensures each rebuild delivers true OEM airflow, zero leaks, and stable temperature control. With ultrasonic cleaning, precision machining, and data-backed testing, Turbo Kings provides compressors built for durability, efficiency, and reduced downtime in demanding routes.
