I've Googled through this group for past posts on this NG and into Yahoo's
MillDrill group to find out what oil should be in the gearhead.
The machine's a brandnew Tong Yang ZAY7032G which Harbour Freight sell as
the #42827. See:
My bugbear is what's the correct oil i'm meant to use in the gearbox?
Castrol has advised their Hyspin AWS iso 68 Hydraulic (for lathes said the
tech) while Mobil DTE medium ~ heavy duty Hydraulic iso 68 is an equivalent.
I went with the Castrol but the problems started immediately..... The stuff
turned to foam in minutes. Castrol suggested add more to the case to cover
the gears but it became a rabbid dog spitting the foam out the breather.
Next was to drain it on the theory that the assmbly fluids were breaking
down the new stuff. It was pretty dirty all right.... added a new batch and
that foamed too....
The manual says use SAE 68 which might exist in China or they have some
other viscosity rateing so i'm at a loss. I imported the machine directly in
a group buy scheme so i don't have an agent to ask. Castrol, bless them have
kind of run for the hills on this one....
Any info appreciated.
