john deere 318

bigdadsputtputt hello could anyone tell me how to check the hydrostat fluic level in my 318 ijust bought it and don't have a manual for it yet also my 317 uses auot tranny fluid type f is that ok for the 318 also.........thank you for lookin
Dave bigdadsputtputt - The transmission fluid on the 318 is checked at a sight glass. The sight glass is located at the rear of the tractor, on the right side. The fluid level should be visible at the midpoint of the glass. The tubing connected to the glass often becomes brittle over time.

Originally, the 318s came from the factory with JD All Weather Hydrostatic Fluid which was red. An alternative was Type "F" transmission fluid, also red. If you need to add fluid and it's red, use Type F transmission fluid. JD All Weather Hydrostatic Fluid is no longer available.

Currently, JD recommends JD Low Viscosity Hy-Gard, which is light amber in color. It's o.k. to switch over, but not to mix. In otherwords, if you plan on changing the fluid, completely drain the transmission, remove the transmission filter, install a new filter, and refill with Low Viscosity Hy-Gard. If you do plan on changing, you may want to replace the plastic tubing for the sight glass. It would be a shame to change the fluid only to find a leak in the tubing.

If you go to the following site:

and click on "Misc 318 Stuff", there's a downloadable maintenance chart on that page that lists filter numbers and other information. The fluid capicity is about 5 quarts. I'd pick up six just to make sure. After four quarts, you need to start the tractor up and "burb" the system by operating the two hydro levers on the left side, several times. Turn "off" and let the unit sit for about 5 minutes, then check the sight glass. Add additional fluid as required.

The change interval for the hydro fluid is 200 hours. If the fluid is red, there's a chance it's original and should probably be changed.

If you have any questions, just post again. - Dave

cheato Are there any alternatives to using the JD Low Viscosity Hy-Gard?

Thank you,
