SPECIAL NOTES & TROUBLE SHOOTING

Paint Coating

Special Notes

With the tractor run-in, nuts and bolts drawn up tight and all adjustments and corrections made, the tractor should be given a new coat of paint. The significant of this should not be underrated as moisture, rust and corrosion have access where bolts and nuts were loosened and the original paint coat has been broken.

A paint spray gun is very useful for this purpose. It saves time and facilitates painting as with it, odd corners can be reached without difficulty.

The original paint for tractors (Tractor red) is available at all Establishments. Be sure to remove oil and grease from all parts to be painted.

Handing Over The Tractor

Grease as per the recommendations.

Check front wheel bearings regularly during the first week and readjust if necessary.

Keep front axle extension clamps drawn up tight.

Check "toe in" of front wheels and adjust to "0" mm 0 as described in the "Operators Manual".

After 50 hours of operation check front wheels and adjust again if necessary.

ENGINE TUNE-UP a.General

The following steps outline the operations in an engine tune-up. These steps point out the parts of the engine to be cleaned, checked, timed or repaired.

b.Diesel Engine

1.AIR CLEANER a.Check the air cleaner, hoses and clamps for looseness or leaks. b.Clean & replace the elements as the recommendatations.

2.DIESEL ENGINE

Operate the engine and observe its smoke levels, power and sound. If it misses, smokes excessively or is low on power, check the following: a.Check and adjust the intake and exhaust valves. (Tappet setting) b.Check the injectors by removing them and checking the nozzle opening pressure (NOP), spray pattern and leakage. Service or replace as necessary. c.Check engine compression while the injectors are removed. If the compression is low on one or more cylinders, make the necessary repairs. If only one cylinder is low, squirt some engine oil on top of the piston and recheck. If the pressure goes up worn rings are indicated; if it doesn’t go up valve leakage is indicated. d.If “c.” above didn’t indicate any mechanical problems, install the serviced injectors and operate the engine again. If the engine still runs roughly or lacks power, then check the injection pump timing. If the timing is correct, remove the pump and have it serviced by an authorized Bosh dealer. e.Check and adjust low and high idle speeds as needed.

3.FILTERS

a.Replace the engine oil filter & Fuel filters elements as per the recommendatations.

4.COOLING SYSTEM

a.Check the cooling system for leaks, worn hoses, loose clamps or plugged cooling fins and clean or repair as needed.

b.Check the water pump for leaks and repair as needed.

c.Flush the cooling system and fill with low silicate antifreeze solution that meet GM 6038 formulation specification. A partial list of acceptable antifreeze product is listed in the Operator’s Manual.

d.Check the fan drive belt for wear and tension.

5.ALTERNATOR

a.Check the alternator drive belt for wear and tension.

b.Check alternator output. Service it if output is low.

c.Check bearing smoothness and replace them if they are rough.

6.STARTER MOTOR

a.Check the brushes for wear and sticking and repair as needed.

b.Check and clean the commutator as needed.

c.Check the drive for wear and replace as needed.

d.Lubricate the bushings.

7.ELECTRICAL WIRING

a.Examine all wires for corrosion, damage or loose connections.

b.Check all switches for proper operation.

8.BATTERY a.Check the battery with a hydrometer for charge. b.Bring the electrolyte up to full with distilled water.
