Does your drive box oil come out looking like this ?

25-2 009

does your oil come out like this ?

this is oil with maybe 10% water in it . Probably caused by lots of short journeys , where the drive box doesn’t get hot enough to make the water evaporate off .
solution , change you oil more frequently , open out the hole in the vent at the breather .

When you change it , try and do it hot , just after a ride is best , leave it to drain , overnight if you can .

Then refill to the correct level .

You may need to do this twice in quick succession , to get all the affected oil out.

Your drive box is an expensive bit of engineering , oil changes are very cheap by comparison .
