MINOR SERVICE AND ADJUSTMENTS
ELECTRICAL SYSTEJI
(MAINTENANCE)
Leads and Terminals
All leads should he maintained firmly secured to avoid chafing and
subsequent leakage of current. Battery leads and terminals must be kept
clean and smeared with Vaseline to protect them from corrosion.
Dynamo
If failure of the dynamo is suspected, have it checked by a David Brown
dealer, who will be able to provide a spare dynamo if extensive repairs are
required.
Normal maintenance is confined to oiling every ¥1onth and inspection
of the brushes every six month� to make sure that they are clean and
properly bedded. Replace the brushes exactly in their original positions to
ensure that they make proper contact with the surface of the commutator.
Make certain that the brushes slide freely in their guides, that the
spring tensions are sufficient and that the leads have clearance and are not
charred or burnt. New brushes should be bedded-in by a David Brown
dealer.
Battery
The battery requires regular attention as follows :-
Check the level of the acid solution, topping up with clean distilled
water. Do not let the level fall b�low the top of the plates.
Have the battery checked by a David Brown dealer every two months.
Keep the outside and top clean and dry.
Never leave the battery in a discharged condition.
Starter
The starter incorporates Bend.ix drive and is operated by a mechanical
switch. Maintenance comprises examination and treatment of the brushes
( as recommended for those in the dynamo) and inspection for freedom of
travel of the Bendix drive.
To free the Bendix drive, remove the starter from the clutch housing
and clean the screwed sleeve with paraffin. Lubricate with thin machine
oil and dust with graphite powder.
Fuse Box
This is on the nearside of the fueJ tank bracket. Should any fault
occur in the electrical system immediately check to see whether the fuse
is burnt out.
Do not renew fuse wire until the fault has been located. Location and
cure of any
·
fault in the electrical system should be carried out by a
David Brown dealer.
