Daan Posted January 3, 2016 Share Posted January 3, 2016 The swarf does look quite big, how long ago was it checked before? I must say though, I have magnets in the diff as well, and the amount of swarf in these (and the gearboxes) is always more than I think is reasonable. Better on the plug than in the gearbox, so I suggest just clean it and refill with clean oil. Quote Link to comment Share on other sites More sharing options...
daveturnbull Posted January 3, 2016 Author Share Posted January 3, 2016 Thanks Daan. The box is fairly new to me so unfortunately I have no idea when the oil was last changed (looked cleanish tho) or how many miles it had done. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted January 4, 2016 Share Posted January 4, 2016 Like Daan, its always worried me a little when I pull the magnetic plugs out and have a Christmas tree on the end, but at least its not still washing round in the oil.

qwakers Posted January 4, 2016 Share Posted January 4, 2016 when i changed the oil in my discoverys gearbox a few days after buying it the swarf was so bad i expected the gearbox to start failing within a few weeks..... it didnt.. .. it took 6 months before 2nd gear syncro let go completely and meant i had to double declutch every time i wanted 2nd....

dailysleaze Posted January 4, 2016 Share Posted January 4, 2016 Looks normal to me. The amount on there is typically dictated by how long since the last oil change. If it was only 100 miles then that would be a bit excessive. Mine looked something similar on my recon gearbox after 8k. When this happens it's time for a new gearbox.

Nigelw Posted January 4, 2016 Share Posted January 4, 2016 I often worried too, but after 10,000+ kms I realized how fruitless any worry was I only tend to get excited about big chunks now and even then only a little, easier to plan a reconditioned box to replace it with and enjoy the rest of the day. when I worked on heavy plant we used to get our oil lab tested, every axle, planetary hub, drop box, engine, gearbox and hydraulic system from everything on the firm, it helped to determine component lifespans and enabled planning of exchange components to minimize machine down times, although expensive, not as expensive as having a 50T digger sitting still with shot hydraulic pumps with 5 or more dump trucks standing idle until it's back up and running, that can take weeks!! Believe me, I had it on my Komatsu PC450 Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted January 4, 2016 Share Posted January 4, 2016 I only worry if there's gear teeth stuck to the magnet ? Mo Quote Link to comment Share on other sites More sharing options...
reb78 Posted January 4, 2016 Share Posted January 4, 2016 If you pinch that swarf between your fingers, it isnt really much metal at the end of the day. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted January 5, 2016 Share Posted January 5, 2016 Looks ok to me. The only worry would be if there were bits of metal stuck to it - rather than particles. Les Quote Link to comment Share on other sites More sharing options...
