LUBRICATION FITTINGS (7 Points each side)

5. F1JEL TILTER BOWL - GASOLINE & DIESEL (Figs. 6 & 7)

Check daily and clean when the water 0 r sedi­ment is visable. Clean filter element when nec­essary.

The fuel filter is located at bottom of fuel tank and is provided for the purpose of keeping dirt and water from entering the ca'r·buretor, or fuel in­j ection pump. However, the best results are ob­tained by using adequate fuel storage handling facilities.

.6. LUBRlCATE LOADER AND RIPPER PIVOT POINTS (Fig. 8., 9 & 10)

Lubricate the loader and ripper pivot points daily or after 8 hours of operation. Use high grade chassis lubricant. Wipe all fittings clean before applying grease.

7. BATTERY (S)

Check the electrolyte solution in the battery at least once a week (40 hours) to see that it is at the proper level. This level should be main­tained to lower edge of filler tube, which is about 3/8" above top of separators.

(f)'. Keep all open flame away from battery as ~ an explosive gas is liberated when battery .' .. is being charged or discharged.

The battery supplied with your tractor has a lead washer type valve in the filler tube to prevent· over filling. Never add anything to the battery solution except DISTILLED OR RAIN WATER. Boiled water will not do. The supply of water should be kept in clean covered vessels of glass, china, rubber or lead.

Loading (Fig. 32)

The H4 - HD4 tractor equipped with a loader makes an exceptional production team - the max­imum 560 roll back of the bucket assists in com­pletely filling it on each pass.

1. In loading from a bank or stockpile, posi­tion the bucket so that it is level with the grolil;1d. The bucket must not be rolled back - thus riding the bucket on the heel wasting power and pre­venting bucket from entering the ground.

2. Move the tractor forward into the stock­pile. As the cutting edge penetrates the material raise the lift arm slightly. Use the forward gear that will provide penetration without ex­cessive engine lug.

3. When the bucket has entered the material far enough to get the bucket full - roll the bucket completely back, taking advantage of maximum breakaway.

4. With the bucket completely loaded the opera­tor backs away naturally and quickly only far enough to allow him to turn and move up to the truck to be loaded.

Increase production: Spot the next truck to be loaded on the opposite side. This will allow the operator to clean up and maintain the loading area. Also by alternating the direction of turn­ing, equal life can be expected from the steering clutches~ brakes and the track assemblies.

Stripping and Stockpiling (Fig. 33)

Stripping of top soil and stockpiling it for later use is a simple matter for this crawler tractor and loader. This is an efficient method of load­ing the top soil for removal.

30

In stripping top soil, start with bucket in a level position and maintain a level cut. If an error is made, reposition the tractor for a level attitude and start the cut over.

To start the cut place the bucket at an approxi­mately 50 angle. With the lift-lower lever in the center of hold position, move the tractor for­ward. In hard to penetrate material, a slight down pressure on the lift arms may be necessary.

As the tractor moves forward the depth of cut can be adjusted by a slight lift on the lift arms or by slightly rolling the bucket back. Cut only as much as the tractor can handle.

When the bucket is full and pushing a good load,

SHUTTLE CLUTCH & TORQUE CONVERTER HYDRAULIC SYSTEM CHECKING SYSTEM

CLUTCH PRESSURE (Fig. 61)

To check the clutch pressure install a pressure gauge at check port "6" (See Fig.). Operate tractor engine at high idle. Pressure should be 21 0 to 230 PSI. NOTE: Check with system at operating temper­ature.

CONVERTER PRESSURE (Fig. 61)

To check converter pressure install apr essure gauge at check port "7" (See Fig.). Operate tractor at high idle. Pressure should be 60 to 120 PSI.

NOTE: Check with system at operating tem­perature.

PUMP (Flow Rate) (Fig. 61)

Rerrove pressure line "I" (See Fig oj from clutch control valve. Connect line "I" to pressure or inlet line of flow rater 0

RerrDve converter line "2" (See Fig.) from clutch control val ve. Connect return line or outl et 1 ine from flow rat er to line" 2" 0

CAUTION: Flow rater return line must be con­nected to line "2". Do not return directly to sump.

Operate tractor at 2100 RPM. Check pump vol­umn to 1000 PSI. CAUTION: Do not exceed 1000 PSI. With flow rater connected in this way, there is no relief valve to protect flow rater or pump.

Pump volurnn should be 8.5 GPM at 1000 PSI and 2100 RPM.
