Umm.. dont forget you can always have them milled out to 3mm.. and salvage if there is no other damage.

Thanks Rusty, that confirms my suspicions that the rotors are shot.  You can bet I'll check ever rotor from now on. lesson learned.

Subject: [FlyRotary] Re: V shape Apex Seal Slots?

Apex Location            Base            Top

 

Seal1                        1.99mm        2.16 - 2.26mm

Seal2                        1.98mm        2.22 - 2.25mm

Seal3                        1.98mm        2.18 - 2.20mm

 

Clearly the slot is larger at the top - is this due to design or is this due to wear?  Lynn??? Anybody?

 

 

Hi Ed,

 

I still have the brand new rotor that was dropped by the ceramic coaters, and I just measured the two un-smashed apex seal slots.  I also measured the slots on the dead rotor that was involved in my oil out adventure.  All the slots measure 1.89mm, with no sign of being larger at the top of the slot than the bottom.  

 

Cheers,

Rusty (my kingdom for a decent contractor)
