Noticed on a pre flight check that I was starting to get more movement in the prop hub on my Macro. Not a great deal so I decided it was ok to fly but I would replace the bearings anyway.
Ordered the bearings £11.50 Each !
When I took it all apart yesterday I discovered that the rear bearing had seized solid probably due to eating the seal, the bearing has spun and mangled the bore of the hub hence the increased play! (and probably explaining in part why I have been burning so much fuel!)
Had to grind off the old bearings, but have now fitted the new ones to the shaft with new circlips.
I am going to modify the hub and turn a stainless steel centre section as a new one is £130! hopefull get it sorted for the weekend!
Good pre flights are essential!
