I know this has been covered many times, and there seems to be conflicting advice, so would appreciate some real world lub advice.
What should I be using in a ferret gearbox?
My initial thought is to use SAE30 (I have a Unity motors up the road that does all the mono-grade oils, so no problem sourcing), or do I use multi-grade.
I took the filler off the gearbox, and its low on oild, but more worrying there is quite a bit of oil that appears to have turned to a thick grease (caused by mixing oils?).
How do I get rid of the deposits before refilling the gearbox (remove the gearbox top plate?).
Thanks
Mick
