lubrication question

[Lynn Eades]

I guess Arie is wondering about the coupling?
According to the Canadian lube chart, grease everywhere......except for the gearbox coupling which took C600 gear oil what ever that is these days. I guess this was after the seals were introduced to diff and gearbox ends? I dont know.
As far as I know, we (New Zealand) only received the earlier carriers without the two seal modifications. Maybe the coupling was only greased on assembly?
How that grease nipple was ever supposed to get any lube to the coupling or speedo drive, I have no idea. I guess if the carrier was hung by its two front tow eyes the gearbox oil would get there. Great design!
