Every 3000 Hours; Checking Injection Pump [Lx2610/Lx2610Su]; Checking Egr System [Lx3310]; Checking Supply Pump [Lx3310] - Kubota LX2610 Operator's Manual

EVERY 3000 HOURS

Always use a 50/50 mix of long-life coolant and clean
soft water in KUBOTA engines.
Consult your local KUBOTA Dealer concerning coolant
for extreme conditions.
1. Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the
radiator with fresh water and empty it again.
Repeat this procedure 2 or 3 times to clean up the
inside.
3. Mixing the LLC
Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then pour it into the
radiator.
4. The procedure for the mixing of water and
antifreeze differs according to the make of the
antifreeze and the ambient temperature. Refer to
SAE J1034 standard, more specifically also to SAE
J814c.

*1 At 1.013 x 10 Pa (760 mmHg) pressure (atmospheric). A high-
er boiling point is obtained by using a radiator pressure cap
which permits the development of pressure within the cooling
system.
5. Adding the LLC
a. Add only water if the mixture level is reduced by
evaporation.
b. If there is a mixture leak, add LLC of the same
manufacturer and type in the same mixture
percentage.
IMPORTANT :
• Never add any long-life coolant from a
different manufacturer. Different brands may
have different additive components, and the
engine may fail to perform as specified.
6. When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anticorrosive
agent. If mixed with the cleaning agent, sludge may
build up, adversely affecting the engine parts.
7. KUBOTA's genuine long-life coolant has a service
life of 2 years. Be sure to change the coolant every
2000 hours or every 2 years, whichever comes first.
NOTE :
• The above data represents industry standards
that necessitate a minimum glycol content in
the concentrated antifreeze.

1. Checking injection pump [LX2610/
LX2610SU]
Consult your local KUBOTA Dealer for this service.

2. Checking EGR system [LX3310]

Consult your local KUBOTA Dealer for this service.

3. Checking supply pump [LX3310]

Consult your local KUBOTA Dealer for this service.

4. Cleaning DPF muffler [LX3310]

1. Remove the ash.
The longer the DPF operates, the more ash (burnt
residue) is collected in the filter. Too much ash
build-up adversely affects the DPF performance.
Consult your local KUBOTA Dealer to clean the
filter.
IMPORTANT :
• The DPF needs to be cleaned with a specific
cleaning device. Do not disassemble the
DPF for cleaning or attempt to clean it
yourself. Consult your local KUBOTA Dealer.

5. Checking turbocharger [LX3310]

Consult your local KUBOTA Dealer for this service.

1. Checking exhaust manifold
[LX3310]
Consult your local KUBOTA Dealer for this service.
2. Checking the radiator hoses and
clamps
WARNING
To avoid personal injury or death:
• Be sure to stop the engine and remove the key
before checking radiator hose and clamp.
• Allow engine and coolant to cool down
sufficiently before checking.
Inspect every year; replace if any deterioration (crack,
hardening, scar, or deformation) or damage occurred.
1. If the hose clamps are loose or water leaks, tighten
the bands securely.
