Bar oil, I can just imagine the folks at Clausing cringing over that one. They provide outstanding protection and performance in most mobile equipment and Other applications subjected to a wide range of ambient or operating temperatures. There is nothing wrong per se using motor oils in a lathe gearbox. Usually the hydraulic power pack is the nastiest thing around, partially by virtue of oil weepage but also because nobody ever goes to work on them and they gather dust. It can also produce excess heat ball bearings. The very high viscosity index of Shell Tellus S3 V helps deliver responsive performance from cold start conditions to full load, severe duty operation.
A test has been carried for the past 40 years with no negative results Mini Morris shares the engine and gearbox oil. Shell had some oils that were only available in the European market. Available in the following sizes: Add to Basket to get quotes: Can't wait for quotes? Then Buy it Now: 20 Litre £51. As I recall some of them were a bit different from other brands. Precision hydraulic systems Precision hydraulic systems require good control of fluid viscosity over the operating cycle and excellent fluid filterability, even when contaminated. Modern, synthetic gearbox oils are a diff cat altogether.
I could almost understand someone putting new automatic transmission fluid in, maybe a really light new motor oil, but a used motor oil? I was kidding about the used motor oil. For further reductions in Environmental impact we offer the Shell Naturelle range of environmentally considerate lubricants. . You tell the Mobil guy the Shell number and he tells you if he has something compatable. I wound up using 10 weight non-detergent motor oil but may change it if I can find a better match. I believe that this corresponds to Tellus 32. Headstock oils was discussed many times here.
Tellus 27 is very close in viscosity to a 10 weight oil. The trouble is that there are too many people offering opions without knowing the facts. There is absolutely no comparison between the 2. Shell Tellus S3 V 46 hydraulic fluids are high performance lubricants that use exclusive ashless technology, coupled with highly shear stable viscosity modifiers. Guess what, the proper oil turned out to actually be cheaper than buying transmission fluid from Wally World.
Practical Machinist is the easiest way to learn new techniques, get answers quickly and discuss common challenges with your peers. I asked why they were chosen and he did not have a really good answer. This discussion on what oil to use in headstocks has been run by a number of times and most lathes call for a fairly light oil. They give excellent viscosity control and protection under severe mechanical, thermal and chemical stresses across a wide range of temperatures. Oils like Castrol Transmax or Synthrax will completely eliminate wear if free of metal particles.
Both are available from Grainger in gallon and 5 gallon containers. However, mineral oil hydraulic fluids should not be mixed with other fluid types e. You don't say what this is for, headstock, gearbox, or apron. Seriously get the motor oil out as soon as you possibly can. Tellus 33 and 37 are 2 that I'm very familiar with. I'm no expert, but this is what I'd do the lathe was my machine. I would recommend flushing the system by running the spindle at a fairly good speed for a 10-20 minutes, drain it, and then refill for use.
Just missing the smiley in the post? It will however prevent a lathe from seizeing up. Maybe if you mix it with some chain bar oil. Automotive engine oils should not be used in lathe gear boxes, use the manufacturers' recomended lubricant. These low end oils suffer of 2 other major problems : they loose viscosity through shear and are poor heat carriers. High levels of thermal stability, outstanding wear protection and excellent air release and anti-foam characteristics make Tellus hydraulic fluids a benchmark product in the industry.
I've found heaver oils can get very hot running in systems with little backlash. If you do a search, you should find a discussion on the Shell Tellus oils. These are used in trannies, etc and since they mix well with most any hydraulic or tranny oil, and do well without foaming, that was my choice, and I was pleased. The old Ford Model T also used the engine oil in the transmission. Final drive oils may eat up bronze bushings and should be avoided. The manufacturers were interested in oils which would apear cheap to the end users, sufficient for the guarantee period and not good enough to prolong the life of the machine spares are big bussines.
