The chaincase contains the final drive sprockets and chains and uses the same type of oil as the hydraulic/
hydrostatic system. (See Hydraulic System on Page SPEC-10-3.)
To check the chaincase oil level, use the following procedure:
Drive the loader on a level surface. Stop the engine.
Remove the plug (Item 1) [Figure 40-30-1] from the front of the chaincase housing.
If oil can be reached with the tip of the your finger through the hole the oil level is correct.
If the level is low, add oil through the check plug hole until the oil flows from the hole. Install and tighten the plug.
