I recently completed a full engine and gearbox rebuild, and have just carried out an oil change at 500 miles. I had fitted a gearbox drain plug with a magnet and was a bit concerned to find an oily "gunge" on the magnet, containing minute particles of metal. The gearbox is working perfectly, although there is a slight whine, (gearbox or primary drive?), noticeable only when pulling gently between about 2-3,000 revs, I think in all gears, although I’m not normally in 4th a those revs. I changed all bearings and bushes, together with new 1st and 2nd gear pinions, together with layshaft 4th. All parts were from AN.
Without the magnetic plug, the metal particles would certainly have gone unnoticed. Should I be worried, or is this to be expected as new components bed in? Photo of metal particles on kitchen towel below.
Thanks for your help.
