FAQ
Q1: Can I use this camshaft for marine main engine?
A1: Not recommended. 3923478 is designed for land-based applications only, without marine anti-corrosion heat treatment. Please select marine-specified camshaft for marine main engine service.
Q2: What is the difference between mechanical pump camshaft and ISC/QSC camshaft?
A2: 3923478 mechanical pump camshaft has no cam position trigger slot. ISC/QSC camshaft (3938163) has a special signal slot for ECU, so they cannot swap.
