I wouldn't recommend using the engine oil to HEF members, or the whole internet community, without the experience to go with it.īut as I said above, if you are in snow type climates (of which I have 0% experience) the lighter oil would be better.Ĭlick to expand.I understand and agree with what you're saying completely.įirst to cover the "easy" topic of using 15W/40 engine oil in hydraulic systems. Some of my dozer customers even use engine oil in their hydraulics, & have done so for many years. Using the engine oil is just simpler - less types of oils to purchase, & for operators to carry for topping up. Seeing that old 455C tranny only convinces me more.ĭon't get me wrong, using a SAE30 tranny oil I'm sure would give similar results - the benefit is in the viscosity - 30 will cling to the gears better than 10 - goes without saying. I have recommended using engine oil to all my Case crawler customers for many years, cause when a machine is using it & when servicing the transmission suction screen - you don't see anywhere near the same quantity of metal flake as with machines that don't - so the wear is just not happening. He has always used engine oil since, well a few yrs back, I pulled a final drive off this machine - with near 30,000hrs on it - I expected to see stuffed crown & pinion for sure - they were like new! I couldn't believe my eyes & if I hadn't seen it, I would never believe it. When he got machine back from repairs, someone told him about using engine oil & he tried it - cavitation problem gone! Machine ran better - less noise, smoother - more viscosity in oil.
Well just before the 4yr warranty was up transmission was rebuilt - hard facing was missing on crownwheel & pinions, 2 sp gears - all parts replaced. I was still on the tools for the Case dealer at the time & lots of time & effort went into 'fixing' the problem, new pumps,hoses, thorough testing of all steel lines etc etc (using case tch oil in those days) - could not stop it. I have a customer who bought a 455C new back in the 80's, he always had cavitation problems when machine was new. But i have seen with my own eyes that it works well - on Case crawler transmissions anyhow. The 850M features easy access and grouped service points - and the enhanced CASE SiteWatch™ telematics provides insight into machine performance, maintenance intervals and more - allowing you to stay ahead of service and achieve optimal uptime.Re using the engine oil - I know it sounds wierd Nige & on paper it should not be good for transmissions. And an “isolated” design further reduces cab vibration and provides a smoother ride. A true positive-pressure cab with advanced sealing helps keep out dirt, dust and noise - creating a working environment with one of the industry’s lowest sound ratings.

And an advanced load monitoring system automatically reduces track speed (increasing torque) with a heavier load on the blade, and increases track speed (reducing torque) with a lighter load on the blade, ensuring that the machine is working at optimal power and efficiency at all times.ĬASE M Series dozers provide some of the industry’s best sight lines down to the blade, the tracks and the worksite with excellent visibility and lots of glass from floor to ceiling.
The 850M allows operators to adjust shuttle (forward-to-reverse) and steering sensitivity to Smooth, Moderate or Aggressive to match conditions on the site. The 850M meets emissions regulations through a selective catalytic reduction (SCR)-only system which, as an aftertreatment solution, ensures that all productive power is put towards the work. Match that with excellent control customization and a load monitoring system that automatically adjusts performance to movement and the load on the blade - and the 850M is extremely powerful, efficient and versatile. Best-in-class horsepower and drawbar pull ensures you always have the power and tractive effort to get the job done.
