Subject: | Re: LEAKING OIL ON PROPSHAFT BY GEARBOX |
Hi Bud & Tim
I appreciate very much your detailed replies to my problem. As Bud says detective
work is necessary.. I didnt need to investigate in depth as over the weekend
I brushed the whole area in denatured alchool and ran the engine again. its
quite evident that the 'leak' is from the propellor hub as Tim alludes. Its true
I did service the propeller unit in the spring and probably was too generous
with the grease and the recent hot weather in the uk with high engine temperaturs
exacerbated the problem.. I am not sure if the brushes absorb oil and grease
but they are not making 100% contact so i will replace them. I have taken
onoard Buds advice regarding the gearbox maintenance but maybe its not necessary
at the moment as the engine is only around 500hrs I bought the aircraft at
400 hrs but it first flew in 2006
once again Bud & Tim Thank you for your response. maybe saved me some hard earned
cash as i was quoted $1500 for a gearbox/seal replacement
Bill
By the way Bud I live quite close to Steve Pitt but have little contact

I had the same problem Bud and found they stressed out because of the taper on
the minibolt head.. When tightened it put stress on the plastic causing it to
crack. Replacing the stainless bolt with a straight shank should solve it

Subject: | Re: Vista ventilators |
Bill,
Finally went to install the Vista vents today but found the lower front screen
in front of the doors is not flat and will therefore distort the Vista vent when
the screws are tightened. How does this affect the operation of the vents and
will it put any undue stresses on the windscreen? Any suggestions on the location
of the vents?
Thanks in advance.
--------
Phil B

You could try the rotax 912 turbo solution. This uses a standard 912
mechanical pump in addition to the two electric pumps. All feed the fuel
regulator and the excess returns to the tank.
You only need one electric pump operating by the way otherwise the
regulator cant cope. The new style mechanical fuel pump on its own will
maintain 27"-28" and therefore keep you flying. Indeed some people here
shut down the electric pumps in cruise claiming that it saves fuel.
The fuel feed goes from the fuel tap to the gascolator and then splits into
the feeder to the electric pumps and the feeder to the mech pump. the
output from all pumps meets at the regulator
