Remove the drain plugs for the front differential and for the rear differential. Allow the oil to drain into a suitable container.
Clean the drain plugs and install the drain plugs.
Remove the dipstick/fill plug for the front differential and remove the dipstick/fill plug for the rear differential.
On the 924K and 930K, add 0.5 L (.53 qt) of 1U-9891 or 9X-2037 Axle Oil Additive to each axle. Note: Do not add the additive to the axles on the 938K.
Fill the axles with oil. Maintain the oil between the "ADD" mark and the "FULL" mark on the dipstick/fill plug of each differential. See Operation and Maintenance Manual, "Lubricant Viscosities" and Operation and Maintenance Manual, "Refill Capacities". Note: Install the dipstick/fill plug completely before you check the oil level. If the dipstick/fill plug is not installed completely, an incorrect oil level reading can occur.
Replace the dipstick/fill plugs for each differential. Operate the machine for a few minutes and allow the oil to flow completely through the axles. Remove the dipstick/fill plugs and recheck the oil level. Add oil, if necessary.
Clean the dipstick/fill plugs and install the dipstick/fill plugs for each differential. Note: The 924K and 930K use a dipstick. The 938K uses a fill plug.
