Yak 52 Nose Gear, upper pivot axles and bushings kit
The Yak 52 Nose gear upper pivot has 4 steel outrigger bushings in the fuselage and 4 bronze bushings in the upper ears of the pivoting nose gear leg, shown as item 3 in the diagram.
The bronze bushings will fail first, evidenced by side to side play in the nose gear leg.
These reproduction steel axles have the nominal 16mm OD size, but the bushings are supplied .002" undersize, so after installation in the gear leg, you can line ream the bronze bushings to the fit desired.
The axles are center drilled and grease Zerk fittings are included.
Spiral grooves in the bronze bushings distribute grease to the bearing surfaces.
New nuts and Cotter pins are not included in the kit so please retain your originals !
