Authoritative Monarch 10ee Modern Oil / Lubrication Chart

[RatchetWerks]

Hey all,

I've been sifting through quite a few threads about which lubricants to use in my 3 oil-sight Monarch 10ee.
I've compiled the following information.
Can someone fact check this?

Namely
- 1 gallon McMaster brand/part number callout
- Center Reservoir oil type.

I've also included links where I found the information at the bottom.

Reference Point	Location Name	Capacity (Quarts)	Schedule	Lubricant	OEM Callout	Modern Call out
1	Rear Spindle Bearing (Left Side)	0.5	6 Months	MO-11	Vactra Light or Shell Hydraulic Oil 27	Mobil DTE Light (ISO32)
2	Headstock Reservoir (Middle)	3	6 Months	MO-11	Vactra Light or Shell Hydraulic Oil 27	Mobil DTE Light (ISO32)
3	Front Spindle Bearing (Right Side)	0.5	6 Months	MO-11	Vactra Light or Shell Hydraulic Oil 27	Mobil DTE Light (ISO32)
4	Tail Stock Spindle			MO-12	Vactra Heavy Medium or Shell Hydraulic Oil 33	Mobil DTE Heavy Medium (ISO 68)
5	Tailstock Ways			MO-12	Vactra Heavy Medium or Shell Hydraulic Oil 33	Mobil DTE Heavy Medium (ISO 68)
6	Apron Drain
7	Apron	0.5		MO-14	Sunoco Way Lubricant #80	Mobil Vactra # 2 Way Oil
8	Gear box Oil Level Gauge
9	Gear Box- Reservoir Filling Point	1	6 Months	MO-12	Vactra Heavy Medium or Shell Hydralic Oil 33	Mobil DTE Heavy Medium (ISO 68)
12	Speed Reducing Unit (Back Gear)	1.5	6 Months	MO-12	Vactra Heavy Medium or Shell Hydraulic Oil 33	Mobil DTE Heavy Medium (ISO 68)
14	Main Drive Motor		12 months	MG-2	Mobilux #2	Mobilux EP2 (NLGI #2)

Modern Fluids	Machine QTY (Quarts)	McMaster Part (5 gal)	McMaster Part (Generic Brand:1 Gallon)
Mobil DTE Light (ISO32) (MO-11)	4	2158K34	3025K25

The gallon containers that you have linked to are not Mobil brand oils. Check the SDS (Safety Data Sheet) link. The ones I checked are "Super Brand", which I'm not familiar with.

You're 100% correct. I forgot to name that column "Generic". I'll update that. McMaster displays them in the same group "Turbine Oil". I'm trying to find a source of 1 gallon qty of these oils, so all the 10ee folks don't have 10 gallons of lubricants sitting in the shop for years

Also for anyone reading, I thought that ISO32 was an ISO standard for oil composition/end use case. It's just a standard for viscosity! You can have oils that serve different purposes with the same ISO callout.

I use Vactra #2 way oil for all the tailstock (also use it for the ELSR end below the tailstock). The tailstock ways would want it and it's good for the quill. Biggest reason is that I've got the can right there and I don't have heavy medium in a squirt can.

I use Vactra #2 as well, also for the apron. For the Sundstrand fluid drive I use a modern hydraulic oil, Mobil DTE 10 Excel 68

I'm sure this has been stated ad nauseum, but use Vacuoline 1409 instead of Vactra #2. Same thing, but with the tackifiers that #2 used to use in the original formula. Vacuoline won't drip and run all over the place.

Where do you get it?

 

[daryl bane]

As I remember, and it been awhile, I went to the Mobil Distrb. in Dallas and bought a 5 gal pail. That probably was over 10 yrs ago, and still 1/2 a pail.

I bought my Vactra #2 25 years ago. A 5 gal pail goes a long way.

So did you end up buying / using those generics?

 

[RatchetWerks]

Yup! I purchase the generics on McMaster. I'm in the middle of refurbishing the carriage / aprons oiling system. So I haven't got to the step, where I actually put the new oil in. You can loosely keep track of my progress on on the YouTube shorts I'm making.

I plan on formally reporting back here after I have a couple hours of running on the machine
