MAINTENANCE AND STORAGE
Method 1 - Filling Through Hydraulic Oil
Fill Port (Preferred Method)
NOTE: A hydraulic oil pump is required to fill
through the hydraulic oil fill port, as
gravity will not work and there is a
small pressure to be overcome.
NOTE: Two (2) quick coupler fittings are
provided in your tool kit to provide
connection between the hydraulic oil
fill port and the hydraulic oil pump
that you are using.
•
Remove the fill port rubber end cap.
•
Attach hydraulic oil pump quick-connect
fitting to the hydraulic oil fill port.
•
Slowly squeeze pump handle and fill res-
ervoir until oil level reaches mid-sight
gauge.
•
When finished filling, release pump han-
dle and disconnect quick-connect fitting
from fill port.
•
Reinstall fill port rubber end cap.
Method 2 - Filling Through Hydraulic
Return Filter Housing
NOTE: Clean dirt/debris from return filter
housing cover before removing.
•
Using a 1/2” wrench, remove the four (4)
bolts (located on top of the hydraulic
return filter housing) and set aside.
•
Remove cover and fill reservoir until oil
level reaches mid-sight gauge.
•
When finished filling, reinstall hydraulic
return filter housing cover and bolts.
Wheel Hub Oil
Fairfield Wheel Hubs
Each wheel hub should maintain a proper
oil level at all times. Less than that would limit
lubrication and overfilling would cause
overheating and machine damage.
Capacity
•

Type
•
Hagie Manufacturing Company recom-
mends Mobil Delvac™ synthetic gear oil
(75W-90) with EP features (complying
with API GL-5/MT-1 specifications).
To check the oil level:
NOTE: Check wheel hub oil level every 100
hours of operation.
1. Position wheel hub so the bottom (oil
drain) face plug is positioned at 6 o’clock
(A).
