Planer gear box oil

Grainger may well have one or more of them. In my Delta I use Mobil 634 which I got at Grainger (it’s in the same family of lubes as the Mobil 627). Regardless, I think you will do well with any of the quality lubes form the auto store and probably save some bucks. I picked what I did because it had some additive that Delta recommended…but truth be told, none of us hobbyists work these planers very hard at all, and I suspect some of those lubes were spec’d based on a much harder life than they actually see. This question comes up frequently, and all brands/weights/whatever are used, and no reported failures yet.

I believe the gear oil is just that. That looks like 100 weight gear oil. I can usually get that kind of think at an auto parts store but I live in a area with farmers, ranchers and oil field people. My second choice would be an oil distributor. They sell to stations and the public as well. Do you have a tractor place like John Deere or Caterpillar? I almost said oil field pump jacks but you might not be in oil country. The SAE-30 weight might be as difficult. The recommended lubrication for bushings and bearings is usually non detergent oil. That is becoming more difficult to find. Chain oil? try motorcycle shop. I like moly grease or. It is black and slick. It comes in a tube. Can get heavier stuff in a can. Used for packing wheel bearings on a car. Get the good stuff. Good luck

Our auto parts stores sell gear oil as do the tractor dealers.

Went to grainger and picked up mobil 80W-90 Hope this is fine. Picked up some grease and SAE-30 oil. Now just have to align the blade and put everthing back in order and hope things will run same or better than before.

You may need a pick of tubing or something to help get the oil into the gearbox, on my Delta they made it almost impossible to reach the fill opening.

I bought the gear oil for my planer at the auto parts store. The chain grease, too.

Both were around 5 bucks.
