ELECTRICAL EQUIPMENT Electric starting and lighting are

considered special equipment, but a large percentage of tractors are ordered with this equipment. It is, therefore, essen­tial that servicemen should be thorough­ly familiar with their design.

Be sure that all electrical connec­tions are tight. A broken or loose ter­minal in the battery charging circuit will cause the generator to burn out.

When working on the electrical system always first remove the battery to ground cable.

If the ammeter shows that the genera­tor is not charging and if the engine is to·be run for a time before looking for the trouble either remove the generator belt or ground the generator terminal, marked "A", under the relay base to pre­vent burning out the generator.

SPE.CIFICATIONS

Drive ••..•••••••• V belt from water pump Output

Cold: 13 to 16 amp. and 7.7 to 8.1 volts at approx. 1800 r.p.m.

Hot: 9 to 11 amp. and 7.3 to 7.6 volts at approx. 1900 r.p.m.

Brush spring tension •••• 14 to 18 ounces Rotation ••• Clockwise, viewing drive end

Regulation. The generator has an ad­justable third brush which permits regu­lation of the output.

On tractors equipped with starting and lighting or with lighting only, the generator output can also be changed by setting the switch control to either "L" or "H." The "L" position places a re­sistance in the field circuit and thus lowers the generator output. The "H" position removes the resistance from the field circuit.

On tractors with starting attacr®ent only the field resistance is located in the cutout relay box. To place the re-

19

sistance in the field circuit and there­by lower the generator output the short cable is connected between the "F" ter­minal on the generator and the "F" ter­minal on the cutout relay box. To re­move the resistance and thus increase the charging rate the cable is removed from the "F" terminal on the relay box and placed under the relay box mounting screw.

Do not set generators above their maximum specified charging rate or the y will burn out.

When replacing brushes, be sure that they make good contact with the com­mutator before checking the charging rate. No. 00 sandpaper wrapped around commutator may be used to sand in the brushes. Never use emery cloth either for cleaning or sanding in.

Cutout Relay

SPECIFICATIONS

Cutout points To close ••••••••••• 6.75 to 7.5 volts To open •••••• 0 to 3.5 amp. discharge

The cutout relay is located in the box on top of the generator. It serves as an automatic switch between the gen­erator and battery. When the generator terminal voltage rises to exceed the battery terminal voltage, the contact points close, completing the circuit be­tween the generator and battery. When the generator terminal voltage becomes less than the battery terminal voltage, the relay points open.

FUEL SYSTEM AND AIR CLEANER

Set the speed control lever at wide-open position and remove pin (18) from the connecting rod adjusting block (19) (Illust. 40). Pull the throttle shaft lever (8) and the gove~nor connecting rod adjustment block (19) up as far as they will go. With these two parts in this position, pin (18) should slide free­ly in place. If the pin does not, adjust the governor connecting rod adjusting block so that pin does slide freely into place.

Service The governor assembly can be removed

from the engine by removing the cap screws from the governor housing, removing venti­lating tube (17), removing cap screw (15), and working governor throttle shaft hous­ing far enough forward to release throttle shaft (8) from the coupling to the butter­fly valve. There are two screws holding the governor throttle shaft housing to the carburetor.

The governor shaft rotates on a ball bearing and a bronze bushing. The ball bearing is provided with a snap ring so that the bearing can take end thrust from the helical gear driving the governor.

view of governor (cover-

31

Illust. 39. Governor viewed from the rear.

The ball bearing (5) on the governor drive shaft should be assembled with the closed side of bearing away from the shoulder of the shaft. The governor lever (6) is mounted on a needle bearing. This type of construct.ion holds friction to a minimum and results in a smooth-acting governor. All linkages should fit freely and have very little end play. Excessive play in governor parts will cause rough operation.

When assembling the ,governor to the engine ~nd carburetor,.be sure the tongue and groove of the thrdttle shaft and but­terfly valve shafta.re engaged. Loo.l;len screws (15) holding the felt retainer to the c·onnecting rod housing and then re­place them. This will prevent any possi­bility of strains and misalinements in the governor throttle shaft. Check the governor linkage for freeness and be sure there is no binding at any point. Clean the idling jet in the carburetor if surg­ing is encountered.

Lubricant is forced to the governor by intermittent pressure from the lubri­cating system and returns to oil pan through opening in bottom of housing.

The purpose of this manual is to pro­vide servicemen with the information re­quired to overhaul and adjust the spring loaded, friction type clutches used in Farm Equipment machines.

the tool is shown in actual use. The Clutch Service Tool Spacer and Gauge Block Application Chart, on page 28, lists the spacers and gauge blocks to be used in adjusting the clutches.

The manual is written around the new Clutch Service Tool, FES-50, shown in Illust. 1. The tool has been developed to provide a more precise method of overhaul­ing and adjusting spring loaded clutches. Refer to the Farm Equipment Tool Man­ual, GSS-125l, for ordering procedure and price. Within the disassembly, reassem­bly and adjustment sections of the manual,

The three types of clutche s illustrated in this manual were chosen in order to show the general disassembly, reassembly and adjustment of all friction type clutches used in Farm Equipment machines. In general, all clutches are overhauled in the same manner. There are some adjusting variations which are explained in the manual.
