Well, if you have a camara available that you can up load pictures, that would be a start, do you have a bench vise at home? a good selection of non-worn sockets would also be needed(find socket that fits compressor nut and a really good 6 point the fits the exhaust wheel.
Check and measure the radial play/clearence and the axial end play before dissassembly.
Good luck,
Kevin.
