Turbiner...awesome thread my friend..we gotta keep this sort of thing up you know...lets make a movie of it ..Quist..Interesting point about the cost of the bearing compared to what the manufactuers charge...the true answer is that we only think they replace the bearings every 25 hours...if you call Boca Bearings or any of the bearing manufactuers they will tell you that the bearings last longer than that..way longer...I challenge you all to request the old bearings to be sent back to you on engine service...I bet we wont get em back..
