I changed oil in my 4 speed.
Also changed engine oil and therefor I don't know how much oil to put in the gearbox.
I also have the Spicer PTO, it was also drained of oil.
So wonder, is it just a matter of pouring in as much as possible until it is in level with the filling hole?
I read in the owners manual 6 1/4 pint plus 1 pint for a PTO.
I lost track of the bootles even though they were only 4, thought I had poured in 3. So in total I have filled in 4 liters. So I guess I should remove 0.5 liter, or 1 pint. Is it that important ?
