HDX500 bearing sizes help??

[bloogyct]

Hi All - i wish to replace the bearings in the 2 bearing blocks that support the main rotor shaft and also the 2 that hold the tail shaft - can anyone confirm the following sizes taken from the manual??

Main Shaft bearing blocks - 8 * 16 * 5

Tail shaft support bearings - 3 * 8 * 4

Is this correct?

Thanks

On my (Lepton) doc they are ref'd o8*o16*5 (intDiam*outDiam*Height) and o4*o8*3FZZ (intDiam*outDiam*Height, F = one flange).

A+

Thanks for the Reply papayankee - I have already replced the main shaft bearings and they were indeed 8 * 16 * 5 - still looking for the tail bearings!!

I am assuming that you need the tail gear case bearings that support the tail shaft. If that is the case,

It is 4x8x3mm MR84ZZ
