bogie isolation valves

[thomasinnv]

On my MC8 I have two quarter turn isolation valves, one for each bogie. they both leak air through the valve handle stem. Is there an o-ring or something serviceable in there? The valves are almost $70 ea. and I would much rather just rebuild them if they have serviceable parts, but there is no kit listed in the parts manual, and there is no schematic either. Anyone know if these are serviceable with readily available parts?

Thomas,

Not to pick at nits, but MCI's don't have bogies, they have tags.  Only Eagles 05 and later (AFAIK) have bogies.

Oh yes, you are correct. Tag means behind drive axle, bogie means in front of drive axle.

Thank you for correcting me, as I am sure NO BODY would have had a clue as to what I was talking about if you hadn't pointed that out.

(to be honest here, I actually had to refer to google to see what the difference was )

I always thought that bogies were enemy aircraft.  I had always heard a dead axle infront of the drive axle refered to as a "pusher".  Maybe it's a truck thing.

If they have screws on the top they just have o-rings if not you buy new ones check Prevost the last 2 I bought were under 30 bucks each also seen the MCI guys just use the flip switch like on doors or the trucks use for different controls

good luck
