I wish my local IH dealer was local. About an hour away. Also, they are not always thrilled to spend a half hour on a busy Saturday morning (when real farmers are spending big money) dealing with my less than $50 part requests.
CDI contains other products and information you need, so please check it out.
Which are rarely in stock, and I have to drive an hour one way, the next Saturday morning.
They even went as far as handing me an OEM catalog (back when they were still in business), I'm guessing so they didn't have to deal with me.
Needed O-rings for a 450 once, took in the old O-rings, they proceeded to bring out the universal Chinese kit of rings, matched them by eye, and charged me $5-$10 each for them. Tractor leaked worse than with the old ones because they weren't the right durometer/thickness.
Called to see if they had an M ammeter gauge in stock, they did, drove an hour to be offered a universal gauge, not correct one with IH markings.
Hopefully your local small business is not like mine.
I support small business when they support me.
My uncles, who actually farm, deal with them on a weekly basis and are offered excellent support and prices due to the volume they deal with them. When they bought the new Early Riser 5 years ago the dealership came out the day we planted and helped us dial it in.
It is what it is.
This is great stuff! I'm working on a full blown, replace everything restoration of a family heirloom C. I never thought for a second that I'd be able to get gaskets anywhere but CaseIH. This is super valuable!
I knew about the Timken guide, and there's also an SKF guide available online too. I have it in PDF form and I got it from the web. I like this one because it'll give me the number for bearings at NAPA. At this time all "BRG" part numbers at NAPA are SKF's and so I just call with these part numbers. That said I'm a former bearing engineer and Timken makes good stuff. The same goes for seals. I know Advance Auto has National Oil Seal, but NAPA has SKF. I think quality of the two is interchangeable, so I make my decisions for oil seals and bearings based on availability and cost.
SKF Bearing Interchange (use to find NAPA part numbers): http://www.skf.com/binary/79-/.pdf
SKF Seal Interchange (use to find NAPA part numbers): http://www.skf.com/binary/81-/.pdf
One last thing to add: Never assume that NAPA, Auto parts, or whatever is cheaper. The bull pinion bearings for my C are half the cost from the dealer than they are at NAPA. Go figure.
Most hydraulic systems can operate using many different fluids, including multigrade engine oil, automatic transmission fluid and more conventional antiwear (AW) hydraulic oil. Which oil or fluid you choose depends on your equipment and how you plan to use it.
While it is not possible to make one definitive recommendation that covers all types of hydraulic equipment in all applications, there are a few key questions to ask yourself when selecting a hydraulic fluid.
Picking the right viscosity grade (sometimes referred to simply as the "hydraulic fluid grade") is the single most important factor when selecting a hydraulic oil or fluid. It doesn't matter how good the other properties of the oil are if the viscosity grade is not matched to the operating temperature range of the hydraulic system where it will be used.
If you choose a viscosity grade incorrectly, your hydraulic components will degrade faster than they should.
To choose the right fluid viscosity grade for your particular system, you will need to consider:
starting viscosity at minimum ambient temperature
maximum expected operating temperature, which is influenced by maximum ambient temperature
permissible and optimum viscosity range for the system's components
Typical minimum permissible and optimum viscosity values for different types of hydraulic components are shown below.
Table 1. Typical Minimum Viscosity Values for Hydraulic ComponentsIf the hydraulic system is required to operate in freezing temperatures in winter and tropical conditions in summer, then it will likely need multigrade oil to maintain viscosity within permissible limits across a wide operating temperature range.
If fluid viscosity can be maintained in the optimum range, typically 25 to 36 centistokes, the overall efficiency of the hydraulic system is maximized (less input power is given up to heat). This means that under certain conditions, the use of a multigrade can reduce the power consumption of the hydraulic system.

For mobile hydraulic equipment users, this translates to reduced fuel consumption.
There are some concerns when using multigrade fluids in hydraulic systems. The viscosity index (VI) improvers used to make multigrade oils can have a negative effect on the air separation properties of the oil.1
This is not ideal, particularly in mobile hydraulic systems which have a small reservoir with poor deaeration characteristics. The high shear rates and turbulent flow conditions often present in hydraulic systems destroy the molecular bonds of the VI improvers over time, resulting in loss of viscosity.
When selecting a high VI or multigrade fluid, it is recommended that the hydraulic component manufacturers' minimum permissible viscosity values (Table 1) be increased by 30 percent to compensate for VI improver sheardown. This adjustment reduces the maximum permissible operating temperature that would otherwise be allowable with the selected oil, thereby providing a margin of safety for viscosity loss through VI improver shearing.
If the hydraulic system has a narrow operating temperature range and it is possible to maintain optimum fluid viscosity using a monograde oil, it is recommended not to use a multigrade for the reasons stated above.
Use these factors, along with other viscosity considerations, to make the best choice for your needs.
DIN ; HLP-D fluids are a class of antiwear hydraulic fluids that contain detergents and dispersants; the use of these fluids is approved by most major hydraulic component manufacturers. Detergent oils have the ability to emulsify water and disperse and suspend other contaminants such as varnish and sludge.
This keeps components free from deposits, but it also means that contaminants do not settle out ' they must be filtered out. These can be desirable properties in mobile hydraulic systems, which, unlike industrial systems, have little opportunity for the settling and precipitation of contaminants at the reservoir, due to its small volume.
The main concern with these fluids is that they have excellent water emulsifying ability, which means that if present, water is not separated out of the fluid. Water accelerates the aging of the oil, reduces lubricity and filterability, reduces seal life and leads to corrosion and cavitation.
Emulsified water can be turned into steam at highly loaded parts of the system. Avoid these problems by maintaining water content below the oil's saturation point at operating temperature.
The purpose of antiwear additives is to maintain lubrication under boundary conditions. The most common antiwear additive used in engine and hydraulic oil is zinc dialkyl dithiophosphate (ZDDP).
The presence of ZDDP is not always seen as a positive because it can chemically break down and attack some metals and reduce filterability. Stabilized ZDDP chemistry has largely overcome these shortcomings, making it an essential additive to the fluid used in any high-pressure, high-performance hydraulic system, such as those fitted with piston pumps and motors.
In today's market, however, zinc-free anti-wear hydraulic oils have emerged as a versatile and environmentally friendly alternative to traditional zinc-based formulations. These advanced lubricants provide excellent wear protection for critical hydraulic components without relying on zinc-based additives like ZDDP. Instead, they utilize ashless or phosphorus-based chemistries to deliver comparable or superior performance, including exceptional thermal stability, oxidation resistance, and system cleanliness.
Hyperion' Synthetic Blend oils are zinc-free, anti-wear, hydraulic oils meet the needs of today's high precision hydraulic systems, turbines and air compressors.
Zinc-free oils are particularly valuable in applications where environmental regulations are stringent or where zinc additives could cause compatibility issues with modern elastomers and seals. With growing demand for sustainable and high-performing solutions, zinc-free anti-wear hydraulic oils represent a significant step forward in lubrication technology, meeting the needs of industries that require both efficiency and eco-consciousness.
If you have considered all of the above questions, it is a good idea to review the OEM's (original equipment manufacturer's) specifications.
There may be a warranty-related reason to follow the equipment manufacturer's recommendations. However, in some applications, especially those with extreme temperatures or other unusual operating conditions, using something different than what the manufacturer recommends may increase hydraulic system performance and reliability. For example, Whitmore uses an ashless (zinc-free) additive system that further enhances the longevity and high temperature performance of the Hyperion' Synthetic-Blend series.
If you do not have the proper training to make such a decision, it's a good idea to talk with a technical specialist, preferably one that is vendor-neutral, because this will truly give you the best recommendation for your needs.
