Removal
1 Park the machine on firm level ground, apply the parking brake. Lower the loader arms and excavator to the ground, switch OFF the engine and remove the starter key.
2 Remove the fixing B at the top of the instrument panel and carefully lift the panel forward to reveal the connections at the back.
3 Disconnect the temperature control cable C by releasing the cable outer sheath from the clips R at each end, and unhooking the cable from the water valve lever S and from the pin T at the control knob.4 Disconnect the re-circulation vent cable D by releasing the cable outer sheath from the clips X at each end, and unhooking the cable from the vent Y and from the pin Z at the control knob.
Replacement
Replacement is the reverse of the removal sequence.
After fitting the cables, operate the heater controls and check that they function correctly.
Adjustment
If the control cable C is not correctly assembled it is possible that the heater cannot be turned fully off.
To ensure that the heater can be turned fully OFF, the temperature control cable C should be adjusted so that the water valve will close FULLY within the range of movement of the control knob as follows:
1 Set the water valve control lever S to the fully closed position.
2 Turn the heater control knob E a small amount clockwise from the closed position, i.e. a fraction before the cold position on the decal as shown.
3 Tighten the cable clips R to clamp the cable outer sheath.
4 Check the heater control range of movement and that the water valve can be fully closed by turning the knob.

| CNH DPA5 support many other software working.Here in this instruction show you guide on how to setup CNH DPA5 work with CAT ET 2023A.
Preparations:
CAT ET 2023A
CNH DPA5
Procedures:
1. Start Program.
2. Click Utilities-->Preferences-->Communications from the menu bar.
3. Click on Communication Interface Device drop down box.
4. Select RP1210 Compliant Device.
5. Click Advanced
6. Select the correct DPA in the RP1210 Communication Adapter Device box.
7. Click OK
8. Check Enable Dual Data Link Service
9. Click OK.
CAT ET 2023A Notes:
Enable Dual Data Link. This checkbox should be “checked” in most cases. However, on some older J1708 (ATA) only vehicles, ET will not work with this checkbox checked. If ET does not connect, try “unchecking”, or “checking” this button.
The DPA product line does not support the CAT Data Link (CDL) protocol that is still common among certain CAT off-highway vehicles and industrial stationary equipment. CDL is a proprietary protocol and there are no generic adapters on the market that support this protocol.
To find out if your vehicle/equipment is CDL or a standard protocol (J1708/ATA, J1939), you should look at the diagnostic connector for that equipment in the service manual.

Caterpillar ET 2023A Diagnostic Software
Fuel from the fuel tank 4 is drawn up by the feed pump 5 and strained by the fuel filter 2. The feed pump is driven by a cam in the injection pump 6.
• After filtration, fuel is fed to the injection pump 6. From there, it is fed under high pressure to the injection nozzles
1. The injection nozzles spray the fuel into the combustion chambers.
• If the fuel pressure in the injection pump 6 exceeds a preset level, the overflow valve 7 opens to allow excess fuel to return to the fuel tank 4
The fuel filter separates any water content out of fuel fed from the injection pump\'s feed pump, and its element removes any impurities.
The injection pump feeds fuel to the injection nozzles under high pressure and incorporates a mechanism for increasing and decreasing the fuel flow.
As the plunger 6 rises and its lead E meets the fuel inlet/outlet hole D,fuel flows through the center of the plunger and is expelled from the inlet/outlet hole. Regardless of how much further the plunger rises, no fuel feed takes place thereafter.
The stroke length F of the plunger 6 during which pressure feed takes place is known as the “effective stroke.”
Injection volume adjustment mechanism
To match changes in engine loading, an adjustment mechanism controls the amount of fuel injected. This mechanism turns the plunger 6 by a given angle, thereby altering the point at which the fuel inlet/outlet hole D meets the lead E. Simply stated, the effective stroke is made longer or shorter. A single control rack 7 is used to rotate every plunger in the engine, so the plungers rotate simultaneously and by the same angle.
Fuel highly pressurized by plunger pushes up delivery valve 3 for injection, and when delivery of pressurized fuel ends, delivery valve returns by the force of delivery valve spring to close fuel passage, thus avoiding reverse flow of fuel. Delivery valve lowers further to rest at its seat, and for this stroke L, residual pressure between delivery valve
and injection nozzle is for an instant lowered. This return suction makes fuel-cutting at nozzles effective and avoids post-injection dripping.
Caterpillar 330GC 563-7224 Filter Wire Harness
● Overflow valve
When the fuel pressure in the injection pump exceeds a preset level, the steel ball R is pushed up, allowing fuel to flow out from the injection pump and return to the fuel tank. This stabilizes the fuel temperature and temperature distribution in the injection pump and keeps the injection rate constant in each cylinder.
