Thanks guys, but now I'm more confused.... (like that's never
happened before!).
I asked this question elsewhere as well, and one person responded
via e-mail with the following:
"The 199-60 kit (for 6.00x6 tires) uses a 30-52 brake caliper
and the 075-01500 torque plate. The 199-62 kit (for 8.00x6
tires) uses a 30-52N brake caliper and the 075-05401 torque
plate"
I'm guessing that the deeper brake disc that comes with the
199-62 conversion kit uses the same caliper, but the caliper
assy. number changes ("N" added to the end) because the
torque plate is different, hence the brake assembly is different.
My logs clearly state that the 199-62 kit was installed, but I
have a theory as to why things didn't "look right" with the
8.50s installed on my '54 180. The logs state that kit 199-62
was installed in 1995 (with 8.00x6 tires). In 2002, the 8.00x6
tires were removed, and 6.00x6 tires were installed along with
(factory original) wheel pants. My guess is the previous owner bought/
found some original wheel panties, went to install them and found that
with kit 199-62 on there, the brake disc stuck out too far and rubbed
against the wheel pants, so he found/purchased the brake discs
and torque plates that goes with the 199-60 kit (for 6.00x6 tires),
and bolted everything together but didn't say boo about changing the
brake discs & torque plates in the logs (blasphemy!).
In any event, I now have the correct (deep dish) brake discs on
there, but I need to procure the correct torque plates. I had
a set on my 170 (w/8.50 tires mounted), and they're identical to
what I have on the 180 except the outer bushing housing is 3/16" - 1/4"
deeper to accomodate the deeper (164-36) brake disc.
The mystery / saga continues....
PS: FYI, I can't call the previous owner and inquire as to what
the heck is going on as I bought the airplane from his widow....
