Position Indicator mechanism, Nose gear, Yak 52
Or, if absent, to remind them this is not the case.
The threaded rearward-facing pivot is a permanent part of the front bulkhead assembly.
One of the many satisfactions of flying a Yak, is that you are able to enjoy the rich heritage of its design. Once something works, they stuck with it.
Red and White barber poles have been poking their noses through the upper surfaces of Yaks' wings since the Yak 3 of the Great Patriotic War.

The Yak Collection's adaptor mates this tailwheel to the existing Yak 55 tailwheel strut using three bolts ( suppplied).

- This modification WILL AFFECT Weight and Balance of your airplane.
- This modification WILL REDUCE Prop Clearance, even though only by a small amount. We measured 1/4 to 1/2"" reduction in Propeller Clearance.
(If your Prop Clearance is this low, you may be interested in TYC's Gear Extension kit for Yak 55..!!.)

Gear Extension kit, Yak 55
Gear sag on your Yak 55 is just a fact of life.
After perhaps 27 years or more, the Gear Leg material creeps a little, reducing your propeller ground clearance. As yet, nobody's making replacement gear legs.
If you have an MTV propeller, the consequences of ignoring insufficient ground clearance could be costly, that one time you might make a slightly dodgy landing.
Why not consider fitting TYC's gear extensions ?
The kit includes all hardware and brake lines. Everything you need weighs just under 6lbs and will provide 19" tail-down clearance with an MTV-9 propeller.
The axle bolt pattern is designed to work with Grove Aircraft wheels, axles calipers and brakes ( not included). Call Gail at (619) 562-1268 for pricing, referencing the part numbers shown on the diagram - and please mention the Yak Collection !
With several sets already in the field, you are invited to contact us for customer referrals and any other questions you have.
Yak 50 Main Gear Trunnion Axle - Replacement
Have you been hearing heavy clunking sounds from the upper ends of your Yak 50 gear lately, during ground handling?
This repair axle may be a solution if excessive wear is present. Bronze bushings are also available - see the drop down below.
The dimensions of this repair axle and bushings set are over-sized so that material from any interfacing surface can be judiciously removed. This is challenging work and best undertaken by those with prior experience. In the case of the Yak 50 trunnion, (being quite rare these days), ‘needing to ‘put metal back’ if too much was removed during the repair, becomes very undesirable. Do a skills self-assessment before attempting this, and ask for help if you know you’ll need it.
The only good clunks are airborne clunks, and only when commanded by the gear lever.

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 !
Yak 52, 50, 18-T, CJ-6 Brake Pads
Each main wheel on the four airplane types listed has 12 pucks, retained by small leaf springs.
The thick wedge on the pad's outer wear surface can be inspected by removing the brake drum. This wedge is designed to indicate remaining pad life - or lack of it. By the time your pads are razor thin as shown by the green arrows, you are probably white-knuckling that brake lever, and not getting much braking in return.
It's entirely probable that these Original Russian parts contain asbestos so good maintenance practices for working with brake dust should be observed both during removal and assembly.
Price shown is per brake pad
