Changing finals and swing box on a '17 volvo ec220el excavator, book calls for sae 140. I have 85w-140 on the shelf, will that be too thick?
It'll be just fine. 85w140 was standard fill for nearly all of them. Especially around here. -15 one day and 85-90 a couple weeks later. Just make sure it's a quality oil, not Joe-Blo's corner store blend of waste oil and grease.
Weird, I'm used to 80w90 (75w90... same difference) or 50wt TO-4 spec (pretty much same viscosity)
10-4 thanks
No yellow metal in Volvo travel boxes. So no low viscosity oils with exotic friction modifiers.
There are few gear oils that aren't yellow metal compatible these days. That's a thing of years and years ago that refuses to die for some reason. I'm not very familiar with Vulvo, never worked on them, just a few dozens hours on a 350 loader... which I liked way better than the CAT 988s.
