Dual split twin volute cast iron turbine shell with excellent thermal fatigue resistance. Double exhaust channel separates exhaust pulses, greatly improving low-speed boost response, stable under long-hour high-temperature mining operation without cracking or deformation.

Large diameter aluminum alloy compressor impeller undergoes ultra-high-speed dynamic balance calibration, large air flow capacity to match high-power 3306 engine air intake demand, effectively lifting heavy-load torque and eliminating black smoke under full-load acceleration.

Reinforced double full-floating sliding bearing matched with multi-layer fluorine rubber high-temperature composite oil seals. Strong anti-oil-leak performance, long service life under 24-hour continuous mining heavy-duty working conditions, greatly reduce maintenance downtime.

Dual-port T4 exhaust flange, large straight air inlet/outlet, oil inlet and return interfaces fully consistent with original CAT turbocharger. Direct bolt-on replacement without modification, perfectly matched with CAT 3306 engine for CAT330B excavator.

Solves common turbo faults: insufficient power, weak climbing performance, excessive fuel consumption and black exhaust smoke. Recovers factory original power output, reduces cylinder liner and piston wear, cuts long-term operation costs for mining construction equipment.

Multiple global air & sea freight shipping channels available. Each turbocharger is pre-oiled for anti-rust protection, packed with thick shockproof foam carton, complete factory inspection report and traceable tracking number for worldwide delivery.

Import duties, local consumption taxes and customs handling fees are not included in quoted price and freight. Buyers shall bear all relevant fees in accordance with local customs regulations.

This GT42 twin volute heavy-duty turbocharger is customized for CAT 3306 engine for CAT330B excavator with casting number 657925-W 360, widely equipped on CAT large mining excavators and wheel loaders. It adopts high-temperature resistant heavy cast iron turbine housing, large flow balanced compressor wheel and OEM assembly calibration standard. It is a core overhaul replacement spare part for heavy mining engineering equipment, effectively shortening equipment downtime and reducing overall maintenance expenses.
