Re: [FlyRotary] Ross thrust bearing
mod
You need to double or triple stack
the thrust bearing to reduce the rpm as running at the limit and by
stacking two bearings will cut the rpm in half.
Without doing this the bearing will
go out in short order.

Hi, fellow
rotary enthusiasts. Attached are two photos of the thrust
bearing mod performed on my 2.17:1 Ross PSRU. The fix was done by Dave
Mix. He can be reached at harborview@rivnet.net As you know, each Ross unit is slightly
different (machining tolerances, etc). Dave will measure your unit and
recommend the best fix considering the shaft, end play, etc.
Given the amount of shaft/play on my unit, this was the best method of
installing the thrust bearing. Some units will have enough room for
two thrust bearings. I was very pleased with the quality of his work
and the fast turn-around time. When I find a good vendor, I like
to pass it on. The cost for this mod was $225.00 plus shipping.
I consider this to be a small price to pay for peace of mind and
reliability. Hope this is of interest to other Ross owners.
