Hi,

Does anyone know what p/ns are involved in rebuilding a Yak-50 landing gear actuator?



The large seals are 45x35x6mm chevron seals. You can get them at AC Depuydt for ~$20 ea: https://acdepuydt.com/contact/

Apparently you need 2x per leg.



I'm trying to chase down a few more parts:

1) smaller chevron seal (don't know exactly what this is for).

2) o-rings (I think for end caps). These should be garden variety metric seals that McMaster or similar can sell.

3) circlips (2x larger and 1x smaller). These again seem like pretty garden-variety metric items.



If anyone has any info, please advise. I called Jill already but they were all out of stock and also nearly $500 shipped for 2 sets.

Those all come in the kits from Jill. $237 + shipping. But if she’s out, sorry.
