NB either a cranked
or flexible ended funnel will be
required for filling oil through the rocker cover filler neck.
10. Replace oil filler cap, run engine and check for any
leaks from the oil filter.
11. Stop engine, allow oil to settle and top up as necessary.
Adjusting drive belts.
Alternator belt.
1. Disconnect the battery earth lead.
2. Slacken the bolt fixing the alternator adjusting arm to the
engine after firstly loosening the lock-nut. (This bolt also
supports the hydraulic pump mounting plate)
3. Loosen the main alternator mounting bolts. (Fig. a1)
4. Loosen the adjuster centre locking bolt. (1) in Fig a2.
5. Tension the drive belt by applying and maintaining a
torque of 10Nm (7.5 lb ft) to the pinion nut while at the same
time tightening the centre locking bolt (Fig. a3).
If a new belt has been fitted the pinion nut torque should be
15 Nm (11 lb ft).
It is important that these torque figures be strictly
adhered to - great care should be taken not to
overtighten the belt or damage to the alternator will
result.
6. Tighten the alternator mounting bolts.
7. Tighten the adjusting arm retaining bolt, not forgetting the
lock-nut.
8. Re-connect the battery earth lead.
It is advisable (and easier) to replace the alternator belt
along with the water pump and air conditioning compressor
drive belts (if fitted) when the camshaft drive belt is replaced
every 600 hrs.
Using an underbody crop sheet for late-season row
crop work will help to prolong the life of the belts and
the alternator
.
