    Riva sc shaft

    Hi, how much stronger is the riva shaft, looks a fair bit thicker and requires more torque to do it up but is it a lot better?

    Thanks Ian

    To me the shaft looks exactly the same except for the S/C threads which are thicker and stronger and support a larger nut, the bearings look like they are made from a diffrent material. I had a chance to see the R&D and Riva shafts side by side and the R&D is lighter since it deletes the holding nut from the gear. Lighter is better as it eases the pressure on the clutch.

    The shafts tend to break because the are over tightened, the original shaft has a small diameter thread that needs very little torque to tighten something like 8 ftlbs. I have also heard of some cases where tha shaft breaks under high rpm and causes major damage to the wheel and housing. Housing are very expensive, throw an E1 and your upwards of $1300.00 The key is to watch the play in the bearings, I had one apart last week where the play was so much that the wheel was touching down.

    +1 on this, I'd like to know as well. My stock bearings looked fine as well with the Riva shaft upgrade.

    I think s/c bearing life will vary;

    1) do you pre-lube the shaft everytime you reinstall the S/C?
    2) are you running hi-boost wheel?

    I plan on checking mine every 15 hours with the E1, if it were stock,maybe 50 hours.

    Has there really been that many shaft failures??? Or is it just the odd one or two where people have fitted incorrectly when doing the wheels

    Cheers

    Good post. I just upgraded to the Riva shaft and C1 at 45 hours. I left the stock bearings in, but checked them. Each time I've removed the SC, I've pre-lubed the Shaft through the fill hole before re-installing the SC. I don't think the C1 classifies as the high boost wheel

    I will check the bearings in another 20-25 hours or so. When I did the Riva shaft, I made sure I put a good amount of oil on the new shaft and on the bearings.

    Good info to know.
