Real Case – How to Fix Low Boost on a Caterpillar 345D Excavator
Equipment: CAT 345D (2019) with C9.3 engine
Fault: Turbocharger 20R-2691 delivers only 60% boost, throwing fault code 1901.
Diagnosis: Clogged banjo bolt screen restricting oil flow → turbine seizure.
Solution: Replace with new Cat 20R2691 cartridge, flush oil lines, upgrade to 15W-40 CK-4 oil, replace air & oil filters. Tested – boost restored to 215 kPa, power back to 301 kW. Preventive maintenance interval shortened to 250 hrs for dusty sites.
What is a Wastegate Turbocharger? A turbo that uses a valve (wastegate) to bypass excess exhaust gas, controlling boost pressure and protecting the engine from over-boost. The Garrett 836250-5002S adopts a pneumatic actuator, reacting instantly to throttle changes for smoother power delivery and longer engine life.
