Applicable truck models
This document applies to the Caterpillar C15 On-Highway Truck Engine, configuration MXS00001-UP. The crankshaft rotation table within the procedure also references models C7, C-9, C-10, C11, C-12, C13, C-15, C15, C-16, and C18, with engine-specific rotation degrees and calibration port locations. The C15 requires 60 degrees of crankshaft rotation in the opposite normal direction, with the timing calibration port located on counterweight 2 on the left side of the engine block. The procedure covers both ADEM III and ADEM IV Electronic Control Modules. For official Caterpillar parts and service information, visit Caterpillar Support.
Who needs this CAT C15 timing calibration manual
Diesel mechanics and workshop owners working on CAT C15 on-highway engines need this document when diagnostic code 22-13 is active — indicating that a timing calibration has never been performed on a new ECM, or after repairs to the front gear train, camshaft, or crankshaft. The guide is essential for anyone replacing an ECM or diagnosing rough running and white exhaust smoke tied to default timing operation.
