"N100D for all transmission and hydraulic oil"

I think your best bet is to drain off a bit of oil and look at it, 90 weight gear oil smells and looks different than hydro oil and then there is the weight difference 90 vs. 10 wt. If you need gear oil I think that gl-4 is a good choice because it is yellow metal safe. I think I am safe in saying that if you have a common sump tractor aw- 32 or aw- 46 should be safe to use, that means your trans, rear end, power steering (if you have it) and hydro system all use the same oil. The front axle should be 90 wt. engine 15-40, but this is a guess.

Your going to want to use 80-90w gear oil in the tranny/rear end/ front axle.

-tranny and rear end are same reservoir. Front end is separate.

Hydraulic system is going to use a 20w hydraulic fluid (do not use the universal tractor fluid)

-We use a h46 hydraulic fluid, some call it a aw46

Injection pump uses ISO 100 (air compressor tool oil)

Hopefully that helps!! Feel free to contact me with any more questions.  Or if you ever need parts!!

Have a great day.

With all due respect Trevor, I feel compelled to ask why you specify ISO 100 “air compressor tool oil” in such an application? As you are presumably aware that Cat, Cummins, Deutz, Volvo, Mitsubishi, Mercedes Benz, Nissan, et al, all have integrated injection pump lubricating systems that use the same oil that is in the engine. Even the air brake system compressors on class 7 and 8 trucks use engine oil. In addition, I cannot find any correlation between an “air compressor tool” and a fuel injection pump/governor. I’m pleading ignorance. Please enlighten us.

Addendum: Most of the free world refers to your “h-46” as ISO AW 46. :yes:

Morning Bob,

Most of the Jinma tractors do not use the oil in the engine to lubricate the pump, they have a separate reservoir on the injection pump.  I have heard of people using engine oil and hydraulic oil in the pump.  The reason we use this iso-100 oil is because it does not break down as fast and lubricates the pump much better for longer.

Also, most of the pumps only hold about 4 oz of oil, so even though it is a pretty spendy oil its not to costly to run it in the pump.  Bit more cost effective to spend a little extra on oil then buying a $500 pump when they go out.

As far as the H-46 goes, that is what is marked on the Mobil 50 gallon drums of fluid that we order :good:

Good day guys!

Well, the fuel injection pump and governor share a common sump in this case. The only things that get oil lubricated are the camshaft, lift pump cam follower, and the governor. The barrel and plunger assemblies are fuel lubricated. There is absolutely no advantage, or necessity, in using the ISO 100 oil. It only has a AGMA rating of 3 which makes it undesirable for that application anyway. I would stick with 15w-40 motor oil, it is less costly, reduces inventory, and less vulnerable to fuel dilution which is not uncommon with these pumps.

AW oil has an anti-wear formulation. Viscosity Grade (VG) oils may or may not have the AW formulation. The VG oils without the AW designation are cheaper, though most are derived from the same paraffinic base stock.

Have a super day. :yes:

Hmmmm interesting,

I  was always under the impression that the ISO 100 would last longer and not break down as fast.  So that is not true?  I am not very knowledgeable on the different types of oil and the applications they are used for.   So a regular 15-40w oil has the anti-wear formulation?  Or it just depends on what type you buy?

Might have to do some more looking into this! :mail:

Yes, all motor oil used to have sulfur along with other anti friction/ anti wear additives, but the sulfur was removed from gasoline engine oil for emissions reasons. The newer diesel oils have very reduced levels of sulfur, but at least still some, so I use it in all my older gas engines that have a standard camshaft. All newer cars use roller rockers for this very reason, the lack of sulfur otherwise causes premature wear of the camshafts of older engines. There are many anti wear additives in all motor oils, more so in diesel engine oil. :good:

AW100 is hydraulic oil that has the viscosity  equivalent to SAE 30w motor oil. I would definitely not recommend it for EP applications since it has relatively low shear strength. The 80w-90 multi-grade gear oil will be fine in ambient temps down to around -10°F.
