Product Overview

Loss of boost, sluggish response, excessive exhaust smoke, oil entering the intake or exhaust, or unusual turbo whine on Caterpillar 3304-powered excavator applications using turbocharger 8S4590 can point to a worn turbocharger after intake restrictions and charge-air leaks are ruled out.

A replacement turbo should be installed only after checking oil supply and drain lines, air filtration, intercooler plumbing, and the cause of the original failure. Correcting the underlying problem protects the new unit.
