How to check the amount of lubricating oil in the
Hurth reverse gearbox
1 Release and remove the dipstick from the top of
the reverse gearbox (A).

but do not engage the thread.

lubricating oil level is up to the groove (Al) in
the dipstick. If necessary, add automatic trans-
mission fluid, ATF type "A", through the dipstick
hole to the correct level. Do not add too much oil.

not damaged. Fit the sealing ring and the
dipstick to the reverse gearbox.
