Chaincases
The chaincase contains the drive sprockets and drive chains. There are two plugs in each
chaincase. One is to drain the oil and the other is to check the oil level. Refer to the
“Maintenance Schedules” on page 123 for change intervals. See “Fluid Capacities/
Lubricants” on page 183 for information on recommended type and amount of oil.
Drive Motors
The travel drive motors do not require periodic lubrication oil changes because they are
lubricated by the oil in the hydraulic system.
Checking and Adding Chaincase Oil
1. Park the machine on a level surface.
2. Perform the “Mandatory Safety Shutdown
3. Remove check/fill plug (S, Figure 112)
from each chaincase housing. If the oil can
be reached with the tip of your finger, the
oil level is adequate.
4. If the level is low, add oil through the
check plug until the oil level reaches the
edge of the hole. Reinstall the check/fill
(S) plug.
Changing Chaincase Oil
1. Raise the rear of the machine to aid in
draining the chaincases.
2. Remove drain plugs (T, Figure 113) on
both chaincases and drain the oil into a
suitable container(s).
Note:
Drain plugs (T) are located inside the
tie-down brackets at the bottom front of the
machine.
3. Reinstall and tighten drain plugs (T).
4. Refill the chaincases according to
“Checking and Adding Chaincase Oil” on
page 147.
