Engine oil No. 46 how does this relates to the engine oil type xxWxx?
The numbers 68 and 46 in hydraulic oils indicate viscosity at 40°C. A 68-grade oil is thicker than a 46-grade oil, affecting flow and performance. Choosing the right viscosity is essential for system efficiency.
Basically, the only difference between HD-46 and HD-68 hydraulic oils is the weight of the product. HD-46 is a 15 weight oil, but HD-68 is a 20 weight oil.
Servo 46 is a hydraulic oil that typically has a viscosity of ISO 46. This means it has a viscosity range of 41.4 to 50.6 cSt at 40°C. It is a medium-viscosity oil suitable for a wide range of hydraulic applications.
i made this mistake on an hydraulic breaker pack,no damage was caused to the pump or breaker.however the operation of the equipment was sluggish until the machine really warmed up.presumably because the 46 oil is" thicker" than the iso 32
vg stands for viscosity grade. Hydrualic oil comes in many grades.
The primary type of hydraulic oil used in case backhoes is 10wt or AW-46. Each type has specific properties for longevity, performance, and resistance to harsh temperatures.
The Ford 134 oil is a Hydraulic/Transmission Oil these appear to answer your question. See the provided links I would however recommend AMSOIL's SYNTHETIC TRACTOR HYDRAULIC/TRANSMISSION OIL ISO 46, SAE 30 See provided link.
Use Bobcat (Orange) Hydraulic Oil. If you don't have access to this use hydraulic ISO 46 for temps of -40 to 80f. Use ISO 100 for +40 to 120f. 10w30 motor oil will also work in a pinch but try not to mix....go back to hydraulic at next change.
