About this 3D model

I made the 2nd Engine to review my uploaded files and data. I found the bad BRG No. as follows; 686ZZ(6 x 13 x 5) to WBC6-12ZZ(6 x 12 x 4) --- Already corrected the original descreption. Sorry! Some difficulties are found to rotate the Rotor, then optional parts are uploaded this time. Impeller-HP101: Increased Inlet portion clearance Impeller-LP101: Increased Inlet portion clearance Red-Prop-Shaft201: Reduced Axitial Interference Turbine- Case101b: Increased HP Rotor Clearance And Convenience for assembly, the following tools are also uploaded too. Exhaust-Align01: Use when assembling Exhaust Duct Front-Support01: Use when Engine to vertical position Turb-Rotor-Base01: Use when assembling Turbine Rotor to Shaft This is not the model to print and assemble easily, I hope your perseverance. Thank you for your interest.
