I have a 6,000 P&H overhead hoist in the shop that is due for a service but only oil spec i can find is USE P&H 486 oil. I cant find any crossover or and reference to an API or ISO grade anywhere.


Any idea where to find an obscure compatibility chart for this oil?
 
If all else fails I would test the old oil for viscosity and buy an industrial gear oil that matches the viscosity. This of course assumes that the old oil is the right stuff which is a big assumption.
 
In the absence of appropriate gear train details, I would consider use of ISO 460 EP industrial gear oils or SAE 140/190 EP gear oils.
 
P&H Specification 486 is an AGMA 5 Non-EP Gear Oil. AGMA 5 is an ISO VG 220.

Thank you! anyone have a preferred oil that meets this spec?

Great info .....
Consider any 80/85W140 of KV @40*C close to 220 cSt.

Go for it, for it's KV @40C of 333 cSt for components protection.
There is no such thing as this Mobilube being too thick for ISO 220, in a gear train system.
 
You would be better off with an ISO 220 non-EP industrial oil. A classification such as 85W-140 implies an API GL-5 type of gear oil. These are normally EP oils with active sulfur-phosphorus packages. Something like a circulating oil with a low to moderate level of zinc dithio would be preferable. These are AW to mild EP oil. Also the multigrade suggests the use of a polymer. Modern P&H gear oil specs recommend non-polymer oils. An 85W-140 can be formulated without a viscosity modifier but most companies use them.

Can you recommend a specific product from one of the majors? im having a heck of a time finding anything not GL5

It's valid that industrial gear oils EP efficacy is typically in between that of GL4 and GL5, however it's a myth that modern day GL5 is corrosive to yellow metals post 2000 or thereabout.
GL4 has a spec limit of Copper Strip Corrosion ASTM D130 of 3b thereabout.
Go google D 130 of current generation GL5 and figure it out.
 
According to ASTM D7450, the GL-5 requirement for copper strip corrosion is a rating of 3 when tested for 3 hours at 121°C. The designation of "a" or "b" is not specified.

Most ISO 220 non-EP oils have a rating of 1a or 1b when tested for 3 hours at 100°C. The higher test temperature for the GL-5 qualification test makes it a more severe test than the generally used temperature of 100°C. Different test temperatures are likely to be use specific, automotive versus industrial.

Regardless of the test temperature and despite what the GL-5 standard specifies ASTM D130 performance requirements to be, ASTM D130 results fall into the following classifications and designations; 1a, 1b, 2a, 2b, 2c, 2d, 2e, 3a, 3b, 4a, 4b, 4c. 3A is described as a magenta overcast on a brassy strip. 3B is described as multicolored with red and green showing (peacock), but no gray. 1a is described as light orange, almost the same as a freshly polished strip. 1b is described as dark orange.

Regardless of the performance limits specified by the standard, realistically, a rating of 3 does indicate copper corrosion by the lubricant.
 
Most ISO 220 gear oils are EP but not GL-5 performance

non EP gear oil is usually synthetic however mineral circulating oils and hydraulic oils would also qualify. e.g.

Mobil SHC 630
Castrol Alphasyn T 220
Hyspin AWS 220
Tellus 220
Magna CTX 220 WT

SAE 50 CF-2 or Cat TO-4 would be there about too.
