Hydraulic System Oil Change and Type Specifications
When your machine is new, the hydraulic system oil and filter should be changed within the first 50 hours of use and every 250 thereafter.
Refill the hydraulic reservoir with engine oil type API SF.CD 15W40 when outside temperature is above 40 degrees F.
Use engine oil type API SF.CD 10 weight when outside temperature is below 40 degrees F.
Replace filter with Terramite / 2-200.5C filter or NAPA / 1759 filter. It is important to follow these instructions to alleviate any cold weather engine starting problems and any pressure or heat related component failure.
DO NOT USE HYDRAULIC OIL! MAJOR DAMAGE WILL RESULT!
For your engine oil requirements and change intervals refer to your engine owners manual.
Terramite T7 Parts Manual
Although what "loud" is may differ from person to person, I would say that the hydraulic traction motors on Terramites are quite loud and whiney. The big thing to remember is only press the pedal lightly when under a heavy load rather than "flooring it". This actually increases the torque and decreases the speed. Best for going up hills with a full bucket.
As far as the correct oil in the hydraulic system, I asked Terramite what to use if I work the Terramite in both 90 degree summer heat and 10 degree winter cold. I was told it is OK to use a multi-weight oil with a lighter heat component, like a 10W-40, etc. As was previously said, DON'T USE HYDRAULIC FLUID!
Thanks guys! :trink40:
Hello all, I just purchased a terramite T5B (1985)..Two known problems (1) backhoe boom will not stay up (leaks down) ?? (2) Right hand side outrigger will not stay up(leaks down) ?? (It will stay planted when down)..Lastly, and I think most important, the previous owner used hydraulic oil (I DID NOT KNOW THIS UNTIL AFTER I BOUGHT THE MACHINE) not engine oil. Any suggestions/HELP will be appreciated.
Ok, its a pain but can I use the backhoe and outrigger for now?
My major concern is the hydrostat tranny...it whines pretty loud... do you think any connection with the hydro fluid?
Yes, I plan on changing the fluid... should I just drain and fill with oil or ???
Paul, when I drain the fluid...should I add maybe 2 or 3 gallons of oil, run the machine then drain again and fill with clean oil?
Is there any way to get an owner's manual for my T5B serial number 580806?
Do Not Flush With Diesel It Will Swell And Soften The Seals As Well As Wash Any Lubricants Off The Metal Parts. Use The Proper Engine Oil You Can Use A Cheap Oil From Walmart Then Replace With A Higher Quality Oil
