Whilst celebrating my now drip-free engine (still weeps in spots though), I sought to double check my valve lash after a couple of flights since pulling everything out and reinstalling same.
Of course I caught some screw-ups...adjustment nuts not torqued down and such but what startled me was to spot 2 needle bearings laying next to the valve spring on #7, kinda under it.
Sooo, I pull off the offending rocker arm, all slathered up in MMO-laced oil and it slips from my fingers. No big deal, I positioned a dump can underneath. carefully counting out each bearing, I came up with 58, not the 56 spec'd in the part catalog; that's counting the 2 I found. After carefully placement, not once but twice; hate when that happens, I realized that those two bearings had been there for the last 653 hours since OH, since I never pulled off the rocker arms on this engine.
BTW, I made a placement tool from forming SS safety wire since it is non-magnetic to push the bearings into place. Doing this involves grinding the end of the wire flat. Also used a 10mm bolt shaft to hold the assembly together for work and placement.
Not something I want to do everyday. Kinda like swapping out the air compressor, timing the air distributor, or getting a root canal.
