Stainless Steel Bearings

[Dave Smith]

Matt:   Yours may have been just shielded bearings.   The ones Verne refers to are sealed.(I think)    I used shielded bearing back in the YS 60-61 days and the grease was gone very soon,but no plug fouling. 
They are shown on Towers site for the EFI engine and they appear to be the sealed type.

  How are you guys keeping the grease in the bearings? The one time I used a bearing packed in grease in an engine, the grease washed out on the first or second flight and fouled my plug. So many have reported using greased up bearings, you have me almost believing it was just my bad luck.

    The stock O.S. 1.4 EFI bearing is stainless and shielded, the one for the RX is not. My original bearing (non-shielded) was shot within 5 gallons and a friend of mine only got 3 gallons on his. I put in the EFI shielded bearing with the shields left in and it's still going strong and smooth after 20 gallons. The EFI bearing is a drop-in replacement for the RX since they both use the same crankcase. I've since bought a second RX and replaced the original bearing with the EFI bearing before I even started it up for the first time. BTW, all bearings are not created equal. I'd recommend the O.S. packaged version as it's an NTN high quality bearing packed with hi-temp grease that'll stand up to the temps we operate at.
