Product Overview
The turbo uses exhaust energy to compress intake air so the diesel engine can make rated power under load. Shaft wear, damaged compressor/turbine wheels, oil leakage, a sticking wastegate where equipped, or a restricted oil supply can lead to smoke, oil consumption, poor boost, noise, or loss of power.
Cross-reference research extends this turbo family beyond S250/T200 to additional Bobcat, Gehl and Deutz industrial installations. Because turbocharger housings and clocking can vary even on the same engine family, the casting/reference number and inlet/outlet orientation should be matched carefully.

Before You Order
Before installing a replacement turbo, verify the original turbo/reference number and inspect the oil feed/drain, intake piping and exhaust side. A failed oil supply or foreign-object damage can quickly damage a new turbo.
Frequently Asked Questions
Q: Should I replace a turbo just because the engine smokes?
A: Not automatically. Injector condition, crankcase ventilation, air restriction, engine wear and oil level can also cause smoke. Check for shaft play, oil leakage and boost-related symptoms.
Q: Why compare housing orientation?
A: Turbochargers can share a core family while using different housings, flanges or clocking for specific machines.
