 |

We are fitting new engine to Cj-6a. This is the only aircraft of the type i
n the UK and I think in Europe and having by now three years as we look aft
er her we still are a bit suspicious. The engine we removed is Huosai
-6J1A s/n 4741913, the engine we are
putting on is HS6A s/n 22H6A973607. It is either new or zerotimed and
the engine logbook states the date of manufacture: 16.3.1997.
We
realized that there is no groove in the air distributor casing to
accomodate the snap ring which is supposed to limit the tacho drive
shaft float.
All the manuals we have, clearly depict this groove and snap ring but on ou
r new engine this groove seems to be missing.
I can quess that there might be different arrangements to locate the drive
shaft (and thrust washer).
Engine illustrated parts Cataloque ( IPC Cj-6 Volume 4 HS-6A) describes thi
s unit on page 134 with snap ring as pos. 11.
There
is, of course, a possibility to use the distributor assembly from the
old engine, but the old engine ran out of TBO and by all signs is worn
and needs major overhaul.
Would be most gratefull if you could help us in this matter.
Thank you,
