Technical notes

The 127-5410 is the Caterpillar camshaft assembly cataloged as "CAMSHAFT A" for the 3512/3512B diesel engine within the Cat 3500 Series Vee platform. As a single-bank camshaft, it operates the intake and exhaust valve trains for one cylinder bank; 3500-series Vee engines use separate left- and right-bank camshafts, so this part covers one side of the 12-cylinder block. Distributor listings (Worldwide Power Products) confirm fitment to both the 3512 and 3512B. Buyers should verify the mating bank camshaft part number and confirm camshaft timing/lobe profile against the engine's arrangement and serial-number group before installation, as Cat 3500-series engines were produced in multiple ratings and timing configurations. Verified against OEM and distributor catalogs only; no superseded or alternate numbers are asserted here.

Compliance

Marine diesel engine internal valve-train component; verify exact engine serial-number group and bank applicability with Caterpillar before ordering, as no class-society or regulatory certification is implied by the part listing.

Frequently asked questions

What engines does Caterpillar camshaft 127-5410 fit?
Distributor listings confirm it fits the Caterpillar 3512 and 3512B diesel engines, which are part of the Cat 3500 Series Vee-configuration platform.
Is 127-5410 a single camshaft or a full set for the engine?
It is a single bank-specific camshaft (cataloged as CAMSHAFT A). Because 3500-series Vee engines use separate left- and right-bank camshafts, the opposite bank uses a different part number, which should be confirmed for a complete valve-train rebuild.
Does this camshaft fit gas (spark-ignited) 3500-series engines like the G3512?
The sources list 127-5410 for the diesel 3512/3512B only. Spark-ignited gas variants (e.g., G3512) use different camshaft profiles and should not be assumed compatible.
