Technical Notes
The BTG7508 turbocharger features a two-part housing assembly with visible clamp-style fasteners connecting the turbine and compressor sections. The compressor inlet displays a polished, machined finish, while the exhaust inlet flange includes two large oval ports and four bolt holes. Small threaded oil feed and drain ports are visible on the housing. Buyers should verify the oil return line drain angle against the specific CAT 3406E 550HP engine installation manual to prevent oil retention. Confirm that the mounting bracket dimensions and bolt hole patterns align with your existing unit or service documentation. LeadTurbo provides technical fitment support to assist with these verification steps for Caterpillar 3406E applications.
