Should I replace gear oil?

I found this stand mixer at my grandmother’s house and it still works great. It has not been used in over 15 years though. Should I replace the gear oil or is this not required? Some oil leaks down through the attachment hole (not in the bowl luckily) and there is a cover at the top that I can pull off where the oil is stored (it is black oil). It does not smell burned when used, only a bit dusty.

Here’s the service manual for the mixer.

On p.6-7 it details how to service the gear box. It says to use grease and not oil to lubricate the gear box.

Which ever they have food grade grease also. It's to stop possible food contamination.



Fair enough, but grease would be less prone to leaking out.



To service the gearbox you should take it fully apart and clean out all of the old grease. This usually requires soaking the parts in white spirit, especially if some of the old grease has become toffee-like. Most of the gears have shim washers, take extra care not to lose them when cleaning out/disposing of the old grease. The gearbox should be re-packed with 133 grammes EP2 lithium grease. Clean the sealing faces and reseal with silicone sealant (the small tubes available from some pound stores are ideal for this).

Nowadays, food safe grease is usually used around the teeth of the large ring gear for the planet hub, although the original install was the same as for inside the gearbox. Do not put food safe grease inside the gearbox; it doesn’t provide the same degree of lubrication to the gears at high speed and will result in damage.

If you add oil or replace it they have special non toxic oil used for cooking. Make sure you use the correct oil.
