After receiving my zf -0, I filled it will oil and every week I spin it for about 2 minutes to ensure the oil is moved around the internals. According to Paul Flemming they can 'rust up' if left dry for a period of time.
The box was inspected cleaned and new seals were installed by Paul. I noticed a small (very small, about 1 drip every 2-3 days) of oil is seeping out from the lower rear cover plate bolts. A common problem which I am about to fix with Dowty washers, a steel washer with an inner rubber seal which when compressed will 'fill the gaps' between the nut and stud threads.
So I plan to remove one nut at a time add the washer and re-tighten.
Finally the question..........
What torque should I use for the rear cover plate nuts, they are M8 thread.
