Fritz1 Posted February 17 Report Posted February 17 Bravo is going to an annual right now, I am not home, A&P states that turbocharger starts developing radial play, turbo has about 850 h, A&P did not sound overly concerned and will bless it for another year, so I am wondering what radial play is permissible, what are the service limits for radial play of a Garrett AiResearch TA 0413 turbo and what is a prudent number to call it quits and pull it for overhaul?
PilotX Posted February 18 Report Posted February 18 If radial play is evident, might be time to swap it. Ours made it 300 hours. 11 AMU away from base, down for three weeks.
Fritz1 Posted February 18 Author Report Posted February 18 Yep exactly my thought, number is probably in AiResearch overhaul manual but have not gotten hold of that yet

At 3:30 in this Hartzell video they show the radial and axial clearance limit tables from the overhaul manual. That should get you in the ballpark if not spot on. Cheers, Rick EDIT: Screen shot of the tables
Fritz1 Posted February 18 Author Report Posted February 18 Rick, awesome, that will do the trick. -Fritz
Pinecone Posted February 23 Report Posted February 23 The other option is to call Main Turbo and see what they say.
