8N gear oil.

[krank]

I have had an 8n now for a couple years. It has a slight drip on the 3 pt arm pin. I have added a small amount of universal as needed. I noticed it getting milky so I just want to dump it all and start over. I went to the tractor store and felt foolish. All the modern designations are foreign to me. A salesman recomended a ISO 46. Reading threads on here I see "10-30" and "90w" which are opposite ends of the scale.
Please tell me a commonly available gear lube for the differential/ hydralics of my 8n.

You have a common sump tractor and the oil needs to be suitable for use as a hydraulic fluid, transmssion gear lubricant, and final drive lubricant. AW type hydraulic oils are for use in dedicated hydraulic systems and not in common sump tractors.

You have essentially two options:

1) Use a gear oil in whatever viscosity grade you like - SAE 90 and SAE 80W90 are the two most common. Your hydraulics will be sluggish in cold weather regardless of the grade.

2) Use a universal tractor transmission oil (UTTO). These are less expensive than gear oil and improve the responsivenness of teh hydraulics in cold weather, It will run you $35/$40 for a 5 gallon pail at your local Tractor Supply. Here is one of the more popular brands.

There is also Mineral 90 which was used at that time. Still avaible at TSC and some auto parts houses and tractor parts houses.

I saw where TSC still offered the 90w mineral oil. I see old hokeys point about it needing to serve three purposes. Called the old buzz that rebuilds 8n and 9ns here in town and he said "all purpose hydraulic oil". Going to another place to see what they have. Trying to keep it under $50.

ou need about 5 gallons worth. Your gonna be closer to $75.

This might work if you want thinner, says GL4 on the container also as well as 10W30. Remember 90W transmission is between 40 and 50 weight on motor oil scale.

Same basic product as the TSC Traveller I linked and about a zillion others.

UTTO is typically labeled as a 10W30 multgrade, GL4 lubricant.

Its actual measured viscosity is around 9.5 cSt@100C with a viscosity index of 140.

In gear oil terms that puts it on the high end of SAE 80.

Good afternoon: I may have missed if someone suggested Hy-Tran. I have used it in my 9N system for many years.

JI Case Hy-Tran, JD Hy-Gard, CNH Ambra Multi-G 134, Kubota UDT, Mobil fluid 424, Shell Spirax S4, Chevron 1000 THF, Castrol Transmix AGRI and a host of others are simply brand names for the same thing - Universal Tractor Transmission Oil (UTTO). You can spend a lot or a little depending on your brand loyalty but in an N-series you will never know the difference......
