Aftermarket camshaft bushing (camshaft bearing bush) 5I-7529A — a direct replacement for the Caterpillar 5I-7529 bushing. It fits the Caterpillar 3066 / S6K / C6.4 diesel engine family (also 3064 / C4.2), commonly installed on CAT 320B / 320C / 320D excavators.
The camshaft bushing carries the camshaft journal in the cylinder block. When it is worn, camshaft end-float and radial play increase — typical signs are a metallic rattle from the timing side, low or unstable oil pressure, abnormal valve timing and, in severe cases, camshaft journal scoring.
Supplied as a camshaft bush (sleeve). It is usually replaced as a set with the companion positions 5I-7527 and 5I-7528 during an engine overhaul. Confirm standard or oversize before ordering; before shipment we verify the removed bushing number, the engine reference and the measured bore.
