| Subject: | Gear Actuators 101 |
With time to hit the hangar being at a premium these days, I was finally
able to get back to N21YK and verify that the source of my air system leak
does indeed appear to be the nose gear actuator. After a bit of wrestling
it has been liberated from the airframe. I'm assuming the flat spots on the
upper / lower collars are grip points to remove the end caps. But that's
about as far as I got before I had to call it a night. If you have actuator
disassembly / rebuild experience, please talk to me...what is the correct
procedure for disassembly and is there anything else I should know about
the process as a whole? I have a seal kit on order from Jill - and all
shuttle valves have been rebuilt / reinstalled.
Thanks all!
Rico

Jill and others will know intimate details, and you should probably wait
until they give them! However, I had no one to ask when I did mine on
my YAK-50 and the one thing I missed was that those ends that you
mention with the flat spots on them *ALSO* have a *LOCK SCREW* that you
have to loosen before putting on the big wrenches to remove the end
pieces. Look carefully. If nothing else, Russian designs are
consistent ... so even though I have never seen or worked on a YAK-52
actuator, my guess is that they too will have lock screws.

They do indeed have the set screws. Between the paint and chipping, it's a
little tough to tell what it is other than possibly a short, shallow
slot...? That gear paint is thick stuff, too. But I appreciate the head's
up, Mark. If there's one thing I've learned on the Yak, it's to do
everything in an "exploratory" manner and to triple the time estimate for
completion! Thank you, Sir!

No problem... you are exactly right, it is easy miss those suckers with all the
paint. In my case, an A&P wanted to put a TORCH to mine to "loosen them up".
Thank Heavens I found the set screw before that happened!
