cant understand why you're only getting oil to one side .my 58 235 has a common carrier in the centre with sepparate front and rear shafts,for some reason the rear is the first to show but the front follows soon after.the front shaft is in the right way round?as its blocked at the outer end.haveing said all that it dose take forever for oil to show,I've come close to pulling the motor a couple of times when i've done an oil change,beginning to get the knack of priming now tho.
