Engine problem - Seneca II
"BDS" wrote I wonder if the bearings could be changed out as opposed to replacing the entire turbo. At what point do you say that it is time for an overhaul of the turbo? I would think that when the bearings need to be replaced would be a very good time. What would be redone on a rebuilt turbo? Cooked out, bead blasted, oil ports cleaned or reamed, or whatever you do to clean out the gunk, new shaft, reface the inlet and outlet flanges, and rebalance the whole thing. It just seems to me that if the bearings need to be replaced, it would be a shame to do that, then have something else go wrong. I don't know specifically about aircraft turbos, but from a sound mechanical preventative maintenance background, it seems to me that this is an important decision, and one that should be talked around to various A & P's, and other owners that have had work done on their turbo, just to make sure that you are not throwing good money after bad. |
