I have always wondered if there was actually a published max wear measureme

reach and sat down with a stack of manuals and started reading.=C2- It's
amazing what can be found with a bit of due diligence.=C2- I found the in

Oddly enough section 12-1 "Brake Disk" only yielded the minimum thickness o

Section 11-1 "Landing gear Wheel" explains the max number of and depth of g
roves in the brake drum and mentions that the drum can be turned to a MAXIM

be turned out to 195mm (new dia). =C2- If you do the math this works out
to just shy of .040 worth of wear.=C2- I am sure these numbers will be a
pplicable to the Yak 18T,50,52 and the CJ6 and many others.
Some of you may recall a shipment of brake drums which were found to be to
small in the ID to fit over the pads.=C2- These must have been the blank
drums as described in section 11-1.
All good info.

Hi John
I had to replace the arms on the tail wheel. I had them machined out of
stainless steel. They are a simple cantilever with a hole at the end for
the spring hook to pass through. I=99ll try and get a photo to you
over the weekend.

While I suspect there are good sources of this in the US, it took us a

our Russian supplies dried up. But we now have a good source, and charge

They are 2 mm smaller outside diameter, so we have a supply nice plated

Dan,
The pneumatic system (gear and flap valves in the cockpits) normally
vent
to the atmosphere via holes in these valves, that is the hiss you hear
when
the gear/flaps go up and down. You should hear it EVERY time the system
cycles.
It's really hard for me to determine what you need by your description
"brake
reducing box overhaul kit (the little box under right side of pilot
seat)"
This is why god invented part numbers! Check your parts books (Vol
#1)
or if you don't have a set go to my web site http://cj6.com/ and you
will
find a set there, or give me a call (509-826-4610 <tel:%28509-826-4610>
) so I can better
understand and make sure you get the correct parts.

Subject: Yak-List: Brake drum wear info
Listers and Lurkers:
I have always wondered if there was actually a published max wear
measurement for the Yak/CJ brake drum. So today I decided to practice
what
I preach and sat down with a stack of manuals and started reading. It's
amazing what can be found with a bit of due diligence. I found the info
in
the PT-6 Trainer Aircraft Overhaul Manual (Airframe Accessories).
Oddly enough section 12-1 "Brake Disk" only yielded the minimum
thickness
of the brake pad, which is 8mm.
Section 11-1 "Landing gear Wheel" explains the max number of and depth
of
groves in the brake drum and mentions that the drum can be turned to a
MAXIMUM ID of 196mm. It goes on to say that if the drum is blank it
should
be turned out to 195mm (new dia). If you do the math this works out to
just shy of .040 worth of wear. I am sure these numbers will be
applicable
to the Yak 18T,50,52 and the CJ6 and many others.
Some of you may recall a shipment of brake drums which were found to be
to
small in the ID to fit over the pads. These must have been the blank
drums
as described in section 11-1.
All good info.
Best,
Doug
