A-Bayonet Gauge B-Oil Fill Cap
Fig. 6-Bayonet Gauge and Fill Cap
Check crankcase oil level with bayonet gauge (Fig. 6). Do not add oil until level is down to bottom mark on bayonet gauge. Do not operate engine with oil level below the bottom mark. If necessary, add oil until oil level is to top mark. Check oil level 10 minutes after stopping engine.
To add oil to engine crankcase, remove oil fill cap located on top of rocker arm cover (Fig. 6).
Variable Speed Cylinder Sheaves
Fig. 7-lnner and Outer Variable Speed Cylinder Sheaves
Lubricate both inner and outer sheave grease fittings every 10 hours or daily (Fig. 7).
NOTE: Grease fittings may be 1800 apart instead of aligned as shown in illustration.

Repair
A loss of pump prime is generally caused by a poor seal between O-rings (1) and tubes (2 and 3) (Fig. 13). Remove and check tubes for a good seal to the O-rings. A bent tube or a damaged O-ring will allow the pump to pull in air.
If the pump is not delivering at least 15 psi (1 .10 bar) oil pressure, repair as follows:
H36610
Fig. 16-Removing Pump
1. Loosen clamp securing oil tube (Fig. 16).
2. Slide oil tube up and out of port in strainer and insert a 1 /2-inch plug into port (Fig. 16). This will prevent excessive loss of oil.
3. Remove the three bolts securing pump housing to transmission (Fig. 16).

Combines - 6600, SideHiII 6600 and 7700 TM-1021 (Jan-84)
4. Carefully pull pump housing (B) (Fig. 17) away from assembly to catch pump drive pin which, in most cases, will fall from drive shaft. Be careful not to disturb shim pack.
5. Remove oil tubes from pump housing and lay complete assembly aside. Remove rotor and stator (C) assembly (Fig. 17). Save drive pin.
6. Install these parts (Fig. 17) new to insure satisfactory oil pressure;
A-O-Ring B-Housing
C-Rotor and Stator O-Port Plate
Be certain grooves in the new housing (B) for oil tubes, are clean before installing new O-rings (A).
7. Clean paint from ends of oil tubes (approximately 2 inches) (52 mm) and blow all paint scales from inside of tubes. Install oil tubes in pump housing.
8. If possible, rotate transmission shafts so that hole in input shaft is horizontal and insert pump drive pin. If shafts cannot be rotated, use grease to hold pin in place.
9. Assemble spacer (F) and spring washer (E) on port plate (0) and install on input shaft in that order (Fig. 17).
10. Coat rotor and stator (C) (Fig. 17) with HYGARO. Carefully place rotor and stator assembly into eccentric bore and over drive pin.
11. Position radial stop on port plate (0) to mate with slot in new housing (B) at approximately 5 o'clock as shown in Fig. 17.
IMPORTANT: The pump housing, when in place, should feel "springy". If a spring force is not felt, check to make certain all parts are in place.
12. Coat threads of attaching bolts with T43512 Loctite Thread Lock and Sealer. Tighten bolts to 35 ftIbs (45 N·m) (4.5 kgm) torque.
13. Force oil tubes into respective ports. Make certain the ends of the tubes are past O-ring seals and are against bottom of port.
14. Secure oil tube with clamp and attach lead on sending unit.
15. Coat threads of oil pressure sending unit with T43512 Loctite before installing.

General Information

Fig. 1-Location of Main Hydraulic System Pump
The pump is located under the operator's seat (Fig. 1). It is driven from the end of the engine powershaft. It's function is to supply hydraulic oil to the main hydraulic system, steering system, Side Hill leveling system, and optional automatic header height control system. Refer to Section 140 for information on the Side Hill leveling and automatic header height control systems. Refer to Section 60 for information on the steering system.
Refer to the chart on the next page to determine the correct model of Cessna pump for a particular combine. The basic differences in these pumps are their gallons per minute delivery and their pressure ratings.
Those 6600 Combines ( -206200) with the single gear type pump have a flow divider built into the pump. This pump draws oil from the reservoir to the flow divider valve which then directs the flow to the main hydraulic control valve and to the steering system control valve.

Fig. 3-Cutaway End View of Dual Gear Type Pump
All other 6600, SideHill6600 and 7700 Combines are equipped with dual gear type pumps (Fig. 2). One set of gears pump oil for the main system and the second set of gears pump oil for the steering system. These pumps do not have a flow divider. Hydraulic oil is drawn from the reservoir to the pump where it is divided by two sets of gears and is directed to the main control valve and to the steering control valve.

Group 5 CLEANING,SERVICING AND REPAINTING
Perform the following service work on a used combine or header, to help insure that you will receive the highest resale value.
CLEANING
1. Wash the outside of engine thoroughly Use diesel fuel and a stiff brush.
2. Use air or water under pressure to clean out any dust or dirt accumulated in radiator core. If the combine is equipped with air conditioning or hydrostatic drive, swing out the condenser or oil cooler before cleaning radiator. Clean the condenser and/or oil cooler after cleaning the radiator core.
3. Clean the combine thoroughly inside and out. Chaff and dirt will draw moisture and cause rust.
4. Equipment that is shipped by truck during winter months must be washed immediately after unloading to reduce corrosion from road salt. Use a "top-to-bottom" sequence. If detergent is used, it must be in correct concentration and rinsed off immediately and thoroughly (from top to bottom). Use only detergents recommended by high pressure washer manufacturer. John Deere PT559 , PT561 , and PT562 detergents are recommended.
NOTE: Green paint that turns yellow after delivery is generally caused by incorrect detergent, excessive concentration, delay in rinsing, or incomplete rinsing.
