SUPPRESSION CAPACITOR

Remove and refit 3D• 10-'Zl

The suppression capacitor can be removed with the alternator in situ.

Remove

1 . Remove nut from tie-bolt.

2. Pull off spade connector.

3. Remove capacitor.

Refit

Reverse instructions 1 to 3:

REGULATOR AND BRUSH BOX

Remove and refit 3D•11-'Zl

The regulator/brush box assembly can be removed with the alternator in situ.

Remove

1 . Remove three screws.

2. Lift regulator /brush box away from alternator.

3. Separate the spade connector.

4. Check brush lengths.

A - new length

B - minimum length. Replace brushes if they are at or below this length.

5. Check brush spring pressure using a compression type spring balance. Press brush to brush box moulding. Spring pressure should be: 1.3N (4.7oz} minimum 2. 7N (9.8oz) new brushes

Refit

Reverse instructions 1 to 3 except:

6. Be careful to avoid damaging the brushes when refitting the regulator/brush box assembly .

Uft arm end float

1 . Release the tabwasher. 2. Slacken the bolt. 3. Release the tabwasher. 4. Fully tighten the bolt. 5. Secure the bolt with the tabwasher. 6. Tighten the bolt, until the lift arms will move freely

throughout their range, but without any end float. 7. Secure the bolt with the tabwasher.

Quadrant location

1. Slacken the two bolts. 2. Slacken the two barrel nuts. 3. Locate the inner quadrant in the centre of the

elongated hole. 4. Tighten the two barrel nuts. 5. Locate the outer quadrant in the centre of the

elongated hole. 6. Tighten the two bolts.

Draft control rod

1 . Place the Draft control lever in the UP position. 2. Place the Position control lever in the TRANSPORT

position. 3. Using MF 333, adjust the set screw to give a

clearance of 5,8 mm (0.230 in) between the setscrew and the lift cover casting.

Draft Control

1 . Slacken the locknut. 2. Unscrew the Allen screw to the end of its thread. 3. Release the tabwasher. 4. Slacken the nut. 5. Position MF 273 on the lift cover. 6. Apply a load of 1,4 kg (31b) to the end of the vertical

lever. 7. Locate MF 356 on the lift cover. 8. Place the Draft Control lever in the SECTOR

position. 9. Place the Position Control lever in the TRANSPORT

position. 10. Adjust the slide pivot, until the vertical lever just

touches the pin on MF 356. 11. Tighten the nut. 12. Recheck the setting. 13. Secure the nut with the tabwasher.

IMPORT ANT: On later model tractors the cut-out in the vertical link has been modified. Therefore care must be

P.,... taken to ensure that the straight edge of the lever rests ~ against the setting pin on tool MF 356, and not the cut­

out, as this would result in an incorrect setting. The tool can bf! converted using Kit MF 356-Z to compensate for this change. Tools stamped MF 356C have been adjusted by the manufacturers to suit the new link.

Position Control

1. Position MF 272 on the lift cover. 2. Locate the ram arm on MF 272. 3. Place the Draft Control lever in the UP position. 4. Place the POSITION CONTROL LEVER in the

TRANSPORT position. 5. Adjust the Allen screw until the vertical lever just

contacts the pin on MF 356. L. Tighten the locknut. 7. Recheck the setting. 8. Remove MF 272, MF 273, MF 356 and MF 363. 9. Refit the nut to retain the lever. DO NOT fit the plate,

spacers and bolts at this stage.
