ENGINES

The vertical, 3-cylinder, valve-in-head, four-stroke cycle engine is available in either gasoline or diesel models. The engines have three in-line cylinders which use individual wet-sleeve liners of the replaceable type.

LUBRICA TION SYSTEM

The engine lubrication system is a force­feed and splash type. The system has a posi­tive displacement, gear-type oil pump, with an externally adjustable pressure regulating valve, and a full-flow oil filter.

GOVERNOR SYSTEM

Gasoline engine speeds are controlled by a flyweight type governor, driven from the engine crankshaft. Diesel engine speeds are governed by flyweights in the fuel inj ection pump.

COOLING SYSTEM

All engines are liquid cooled and are equipped with pressure cooling systems having a centrif­ugal water pump and a bypass-type thermostat.

SM-2063 (Jan-66) Litho in U.S.A.

FUEL SYSTEMS

The large-capacity fuel tank on all tractors is located behind the operator's seat.

GASOLINE

Gasoline fuel systems are fed by a fuel transfer pump driven by the engine camshaft.

A replaceable fuel line filter cleans fuel before it enters the single-throat, updraft car­buretor.

DIESEL

Diesel fuel systems are fed by a fuel trans­fer pump driven by the engine camshaft.

Diesel fuel is filtered by two stages of re­placeable micronic filter elements. Fuel sedi­ment bowls are located under each filter.

Fuel is delivered to 9.5 MM injector nozzles by means of a distributor type fuel injection pump.

Make all diesel speed control adjustments in the exact order given here. Refer to Fig. 40-10-19 as a guide.

IMPORTANT: Be sure engine is at operating temperature before making speed adjustments. Use a master tachometer. All speeds given are for engine at no load.

1. Disconnect speed control cable from in­jection pump arm (8). Loosen cable clamp (7).

2. Run engine and rotate pump throttle arm until fast idle stop screw (10) contacts its stop. Engine speed should be 2650 ±50 rpm. If not,

SM-2063 (Feb-69) Litho in U.S.A.

adjust pump stop screw (10) to correct. Lock screw with sealing wire.

3. Lightly rotate pump throttle arm to slow idle pOSition. Engine speed should be 800± 50 rpm. If not, adjust slow idle stop screw (9) on top of injection pump.

4. With speed control cable disconnected, move hand throttle forward and then rearward only to the detent-against machined stop on friction link (3). Adjust length of speed control cable to match pump arm at point where engine idle speed begins to increase. (Make minor ad­justment at swivel end (8). For more travel, adjust cable at yoke (5) under dash. Be sure to connect yoke to rear hole (4) in pivot lever.)

Group 20 ALTERNATOR (Motorola)

(Tractors 15485-Up)

DESCRIPTION AND OPERATION

Fig. lOO·20-1-Encloserl Altemotor

The alternator (Fig. 100-20-1) is completely enclosed to protect the component parts from dust and water. The enclosed brushes also pro­tect against sparking in an explosive atmos­phere.

Operation of internal parts is very similar to that of alternator used on earlier units. See page 100-15 -1 of this r.nanual.

ALTERNATOR SYSTEM TESTS

To trouble shoot the alternator system on the tractor, refer to Group 10 of this Section.

REMOVAL

CAUTION: DisCOMect the battery ground straps first to prevent damage that mtghtoccur If wire leads removed from alternator should be grounded to tractor.

Disconnect wires from alternator. Slip fan belt off and remove alternator.

SM-2063 (Jan-66) Litho in U.S.A.

REMOVING AND CLEANING BRUSHES

Clean alternator brushes will assure full charging of the alternator at all times.

~g. INSULATOR

~ ~ T 12972 ~ ~

Fig. lOO-20·2-Alternator Brush Assembly

NOTE: It is not necessary to remove the al­ternator from the tractor to clean the brushes.

Remove the two screws holding outer brush cover and swing the cover open. Remove the two screws retaining the brush holder. Carefullyre­move brush assembly and insulator. Be sure to note how insulator was installed in the alternator so it can be installed in the same manner.

Replace the brush assembly if brushes extend less than 1/4 inch beyond the holder.

If the brushes are clogged with dust or dirt, clean with compressed air. Avoid using any type of liquid as this increases the possibility of dust or dirt hardening in the brush cavity and hinder­ing the movement of the brush.

If Slip rings are contaminated, clean with a non-petroleum base cleaning solvent. If the sol­vent does not clean the Slip rings, use crocus cloth.

Remove oil pan from bottom of housing. Re­move inner bearing cover and gasket from hous­ing. Remove cotter pin, hex. nut, and washer from flanged axle shaft (Fig. 140-10-5).

Remove the two countersunk-type pipe plugs from final drive housing.

Attach JD220 puller to final drive gear as shown in Fig. 140-10-6 and screw puller legs into JD220 pullers.

Fig. 140·10.6-Removlng F/angeJ Axle

It is advisable to use a shaft protector to prevent damage to end of shaft during gear pull­ing operation. Make sure that the shaft protec­tor will pass through the inner bearing cone.

Apply pressure to end of flanged axle until final drive gear breaks loose from spline. Then slide flanged axle and outer bearing free from housing.

Unscrew puller legs and remove final drive gear, inner bearing cone, and spacers from final drive housing. If bearing cups are damaged, re­move and replace.

Track System Tracks

TRACK PINS AND BUSHINGS

Due to the fact that the wear on pins and bushings does not extend over the entire surface of these parts, the life of worn pins and bushings can often be restored by rotating them 180 degrees with respect to the track link (Fig. 150-10-3).

To determine when pins and bushing should be turned, other measurements of wear may be taken in addition to measurement taken with track wear gauge:

(a) Bushing Outside Diameter Wear: Measure outside diameter of buShing, which is 1. 7495 to 1.7505 inches on new parts. If external bushing wear is not more than 0.090 inch, bushings may be rotated without replacing them.

Fig. lSO.JO-2-Measuring Internal Bushing ana Pin Wear

(b) Internal Pin and Bushing Wear: Pull the track as tight as possible and measure across four track links (five pins) as shown in Figure 150-10-2 to get measurement of worn parts (master pin and link must not be included). Re­peat this measurement on another group of four links to get an average figure. Measurement of new track across four links and five pins is 23.01 inches. If wear shown by extra distance does not exceed 0.440 inch (or O.llO-inch wear per pin and bushing), pins and bushings can be rotated and will normally give extended track life. Note, how­ever, that if forward edge of front idler is flush with front edge of track frame, allptns and bush­ings should be replaced.

SM-2063 (Feb-67) Litho in U.S.A.

NOTE: Working conditions may increase or decrease the wear limit of 0.110 inch because of the different amounts of stress placed on pins and bushings in different soils.

T 10311

Fig. lSO-10-3-Rotating Track Pins ona Bushings

Refer to Figure 150-10-3 and rotate worn pins and bushings 180 degrees as indicated.

IMPORT ANT: Allowing Pins and bushings to wear out without rotating them will resultinac­celerated wear to all track companents. If pins and bushings are rotated in time, langer track service life will result.

Inspect pins for cracks, Chips, excessive wear, or looseness in links. Look for evidence of pin freezing in bushing which will cause pin to be rough. If this condition is found, smooth pin with emery cloth.

TRACK LINKS

Inspect links for cracks, chips, or worn bush­ing or pin hole.

TRACK SHOES

Inspect shoes for cracks, damaged or worn lugs, and looseness on links. If lug is worn or damaged beyond further use, replace shoe.

IMPORTANT: Be sure track bolts are kept tight as loose track bolts are a source of dam­age to shoes and links. Lubricate track shoe bolts and nuts and tighten to 110 ft-lbs torque.
