Sorry if this is a silly question, but can anyone tell me what today's equivalant to SAE 20W oil is? I see in my D14 owners manual, that 20W oil is recommended in many of the gear boxes. Is this just motor oil? Thanks. |

The 821 oil available at your dealer is a better oil than plain engine oil. It has anti-wear additives for gears and bearings.

Ok, thanks. I actually have a MF1643 and just changed the hydraulic fluid, so I have plenty of 821 sitting at the house now. I didn't realize that SAE20W was the equivilant to hydraulic oil. |

All the new oils in the Trans-Hyd oils are blended to replace the old #20 oil used for hyd and gear oil of the past. these now have anti-foam, anti-wear, properties that the old oils did not have.
Same as the mult-grade engine oils now replace the straight weight oils used in engines. Since these old tractors were made progress has been made in oil and in tractors but new oil work fine in old tractors and old tractors work great with the new oils. ------------- Faith isn't a jump in the dark.

Oh, oh. You just pulled my string!!! LOL There is no such thing as 30w or 40w oils. The "w" stands for "winter" and specifications for winter oil stop at 25w (not that it's around). ------------- Mark B10 Allis, 917 Allis, 7116 Simplicity, 7790 Simplicity Diesel, GTH-L Simplicity Ignorance is curable-----stupidity is not. |

| Universal tractor fluid or hytran is 20 weight oil. |

| Thanks everyone for the answers. Got another one...how about the SAE 80EP that is called out for in the transmission? Is a 75W90 gear oil acceptable? |

And your 821 hytran fluid will work fine in the tranny too.

The newer hy-tran oils are great, but because they are so thin the have a tendency to seep through the old gaskets, so leaks are probable. ------------- Most problems can be solved with the proper application of high explosives. |

A 20 weight oil is still a 20 weight oil at operating temp. It's just that the new oils don't thicken as much at cold temps as the old oils do. In other words, they shouldn't leak much different. ------------- Mark B10 Allis, 917 Allis, 7116 Simplicity, 7790 Simplicity Diesel, GTH-L Simplicity Ignorance is curable-----stupidity is not. |

That is true if you are using it in the hydraulic system. If however, you use it in place of 80-90 gear lube in the tranny and differential, it could find spaces to leak from that 80-90 wouldn't. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |
