Technical Updates

ISL9 CM2350 L101 Engine Unable to Accept PTO Load at Idle Engagement - QSOL Reference: TSB190129. The amount of boost pressure coming into the engine is not enough to sustain engine load, resulting in an engine stall.

X12 CM2350 X119B Crankcase Breather Tube Lubricating Oil Leak at Rocker Lever Cover Attachment Point - QSOL Reference: TSB190133. Excess material on the rocker lever cover can interfere with crankcase breather tube sealing ability.

ISB, B6.7, ISL, L9 EGR Cooler Pressure Test - QSOL Reference: TSB190128. An instructional video was developed to assist in performing the exhaust gas recirculation (EGR) cooler pressure test. The EGR cooler pressure test provides a pass/fail specification, for diagnostic practices of internal leaks in EGR coolers. On engine testing will reduce unnecessary inspections or replacement of EGR coolers.
