Remedy
10.4. HYDRAULIC LIFT LINKAGE SYSTEM
Linkage would not rise or its lifting capacity
sharply drops. With one of the distributor han-
dles set to «Lift», the pump «squeals». As a
rule, oil is overheated.
1. Oil level low in the tank; top up to the level re-
quired.
2. Air inleakage in the pump suction line: locate and
remove.
3. Distributor bypass valve sticky; wash the valve.
Drop in linkage lifting capacity as oil is heated. It
restores as oil is cooled.
Wear-and-tear of the oil pump
– replace the pump.
Draft-controlled mounted plough jumps up from,
or works deeper into, the soil with a slight move-
ment if the handle.
Draft sensor spring broken
– replace the spring.
Excessive oscillations in the hydraulic system
when lowering the tool.
1. Broken or slacken spring
– replace the spring.
2. Broken stop
– change the stop.
10.5. ELECTRICAL EQUIPMENT
Storage Battery Low Charge Level
Low level of controlled voltage.
Replace the alternator voltage regulator.
Alternator drive belt slipping.
Adjust tension of the alternator driving belt.
Increased contact impedance between SB termi-
nals and wire clamps due to slackening or oxida-
tion.
Dress the terminals, tighten and smear non-contact
parts with petrolatum. Tighten up the SB switch con-
nections and «frame» jumpers.
Alternator faulty (no voltage on terminals “+” and
“Д”).
Dismantle the alternator and send it to workshop for
repair.
Storage battery defective.
Replace the storage battery.
Storage Battery «Gasses» Excessively and Requires Frequent Refill with Distilled Water
High level of controlled voltage.
Replace the alternator voltage regulator.
Storage battery defective.
Replace the storage battery.
Starter Would Not Switch ON and Fails to Crank the Diesel-Engine Crankshaft
One of cable lugs to the storage battery discon-
nected.
Tighten the terminal clamp reliably on the storage
battery.
Excessive oxidation of wire lugs and storage bat-
tery terminals.
Dress storage battery terminals and wire lugs; smear
non-contact parts with petrolatum.
Diesel-engine start-up interlock operates or one of
its switches faulty.
Shift the GB lever to extreme left-hand position or
replace the faulty switch.
Starting torque too low due to storage battery run-
down
Charge the storage battery, as required.
Diesel-engine is not ready for start at a tempera-
ture below + 5
O
C
Prepare the diesel-engine for start-up.
Starter faulty
Remove the starter and send it to repair shop.
