Hi everyone. Hope someone can shed some light....
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:
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.
Pete
