BDizzle Posted May 3, 2011 Share Posted May 3, 2011 Where in the T-56 are labyrinth seals? Are they easily replaced? I understand the concept, but not sure where they physically fit into the motor. Quote Link to comment Share on other sites More sharing options...
Lkuest Posted May 4, 2011 Share Posted May 4, 2011 They follow all of the main bearings, except for the zero bearing. The numbered bearings are located both in front and behind the compressor, and again in front of and behind the turbine. The #4 is the only one that is easy to reach, as you only have to tear apart the rear bearing support assy. The #3 requires removal of the turbine assy. The #1 and #2 lab seals, as far as I know, requires you to basically tear the engine down to the compressor assembly. Quote Link to comment Share on other sites More sharing options...
DanGothe Posted May 4, 2011 Share Posted May 4, 2011 LKuest you are correct in your reply. Unless BDizzle is allowed then that is a Depot Function as I know here at my base we can't get into the compressor area. But can do the # 3 & # 4 Quote Link to comment Share on other sites More sharing options...
BDizzle Posted May 4, 2011 Author Share Posted May 4, 2011 We had a plane loose a few gallons of oil in flight, the maintenance folks said the lab seal was suspect. Sounds like the turbine ones can be done on base and the compressor ones require engine change, so I guess it just depends on what they find. I wanted to gain some knowledge on the subject.
