MAINTENANCE/SERVICE
HYDRAULIC SYSTEM (continued)
Hydraulic Oil
The combine adapter’s hydraulic system provides
oil for the draper and feed drum drives.
Check oil level every 25 hours at dipstick (A).
Maintain level between "LOW" and "FULL" marks
when oil is cold.
Capacity:
- Full system: 25 litres (6.6 U.S. gallons)
- Tanks only: 17 litres (4.5 U.S. gals.)
Type – See recommended lubricants, page 18.
NOTE: When ambient temperatures are above
35º C (95º F), maintain oil level in the low portion
of the range to prevent overflow at breather under
operating temperatures.
Change hydraulic oil every 1000 hours or 3 years
To change hydraulic oil:
1. Remove dipstick cap (A).
2. Remove plug (B) at right reservoir and hose (E)
at left reservoir.
NOTE: A drain pan with a capacity of 15 litres
(4 U.S. gallons) will be required for each
reservoir.
3. Replace the hydraulic oil filter. See below.
4. Replace plug (B) and hose (E) and fill the
reservoirs through female coupler (D) from a
pressurized oil source.
NOTE: Do not use cap port (A) to fill system.
Oil will not reach left reservoir. If a pressurized
source of oil is not available, pump oil from
right reservoir to left as follows:
•
Fill R/H reservoir with oil through cap port (A).
•
Run the adapter pump until feed drum stops
turning.
•
Re-fill R/H reservoir.
•
Repeat procedure until oil level in R/H reservoir
remains between LOW and FULL on dipstick.
5. Replace cap (A).
Hydraulic Oil Filter
Change hydraulic oil filter (C) after the first 50
hours operation and every 250 hours thereafter.
To change:
1. Clean around the filter head.
2. Remove the filter and clean the gasket surface
of the filter head.
3. Apply a thin film of clean oil to the gasket on
the new filter.
4. Install the new filter. Turn the filter onto the
mount until the gasket contacts the filter head.
Tighten the filter an additional 1/2 to 3/4 turn by
hand.
IMPORTANT: Do not use a filter wrench to install
the filter. Over-tightening can damage gasket and
filter.
