Metal particles in CARC oil

    I'm asking for help with with my CARC. I recently split the CARC as part of my restoration project last year, to replace the large 18 ball race with a 19 ball version. I have just drained the oil (at +600 miles) to replace the oil seal that is leaking. I have found a large amount of metal particles in the oil. There are no flakes just fine fillings.

    I decided to split the CARC today to check internally. The large ball bearing runs very smooth as does the smaller outer bearing on the main, large bevel bear shaft. The gears turn smoothly and there is no sign of play or anything untoward. It is very hard to see the bevel gear teeth or check the condition of the needle rollers with out disassembly.

    Does anyone with knowledge have any suggestions for my next step?

    The only thing I can think of is that it is from the main bevel bearings not being in the correct home position when the CARC is closed up. So this could put a side load on those bearings. Before I had not changed anything except for the large bearing. So it should be as it was before when the oli was always free of particles. The only change has been that it was opened and closed and a new large bearing fitted.

    Here is a photo of the oil. The old oil seal is in there as I was replacing it with a new one after an oil leak from the seal.

    Have you used a magnet to determine if particles are ferrous?

    moving a magnet in the oil picked up nothing. Holding a magnet below the plastic container made no force lines and made no visible disruption to the bands of contamination in the oil.
    I'm now scratching my head as the gears and bearings are all magnetic.

    Are you using a different brand of oil? Did you possibly get water contamination? Put in an oil you have used before and run 500 miles and check the oil for contamination again. Could be most anything and a change may clear it up.

    The same oil as before. OK I will run it some more and keep an eye on it. Thanks John
