Does the pump has to be on all the time? - Intex 1000 Gallon Swimming Pool Filter Water Pump ()

Timing a Ford 7500 turbo backhoe involves adjusting the timing of the engine's fuel injection pump. Here are the general steps to time a Ford 7500 turbo backhoe:

1. Locate the timing marks: Look for the timing marks on the engine's flywheel and the timing cover.
2. Clean the timing marks: Clean the timing marks to ensure they are visible and easy to read.
3. Rotate the engine: Rotate the engine in the direction of normal rotation until the timing mark on the flywheel lines up with the pointer on the timing cover. This indicates that the engine is at Top Dead Center (TDC) on cylinder number one.
4. Remove the fuel injection pump: Remove the fuel injection pump from the engine.
5. Adjust the timing: Rotate the fuel injection pump until the timing marks on the pump housing line up with the timing marks on the engine. The exact timing specifications may vary depending on the engine and fuel injection pump model.
6. Reinstall the fuel injection pump: Reinstall the fuel injection pump and secure it in place.
7. Verify the timing: Rotate the engine again to make sure the timing marks still align correctly.
8. Test the engine: Start the engine and test it to ensure that it runs smoothly and efficiently.

It's important to follow the specific procedures and timing specifications provided in the engine's manual or by a qualified mechanic. If you're unsure about timing your Ford 7500 turbo backhoe, it's recommended to consult with a professional mechanic or technician.

Setting the timing on a Kubota injector pump PFR 3kx type involves a complex and precise process. Here are the general steps to follow:

1. Remove the injector pump from the engine.
2. Locate the timing marks on the engine and the pump. The engine timing mark is typically on the crankshaft pulley, while the pump timing mark is usually on the pump body.
3. Rotate the engine to the top dead center (TDC) position for the cylinder you are working on. This can be done by inserting a tool into the engine's timing hole and turning the crankshaft.
4. Install the pump drive gear onto the pump shaft in the correct location. This may involve aligning the keyway on the shaft with the key on the gear.
5. Align the pump timing mark with the engine timing mark. This ensures that the pump is timed correctly with the engine.
6. Install the injector pump onto the engine and torque the mounting bolts to the specified torque value.
7. Reconnect the fuel lines and any electrical connectors.
8. Turn the engine over several times to ensure that the pump timing is correct.
9. Check the engine's performance to ensure that it is running smoothly and efficiently.

It's important to consult the manufacturer's service manual for specific instructions and torque values, as the timing process can vary depending on the model and type of Kubota injector pump. If you are unsure about any step of the process, it's recommended to seek the help of a qualified technician.

I have been doing research on the Delphi pump and it apparently is associated with lucas/cav and as such is timed by the use of a dial test indicator that, through the use of a plunger and cam, runs on the cam block in the pump and determines when injection begins. Initial timing is to set the flywheel on the injection timing mark and the pump flange mark set on the timing case mark. To get it exact I would recommend that you have a diesel pump shop do the timing using the correct tools. As the pump is not electronic as such (from my research into Delphi ) it is basically a manual injector with a electronic controlled governor. Any way the best advice is to have a pump expert set the timing.

the fuel pump don't turn on every time . first when the pump as prime or if system is prime the pump will not turn on
the PCM give a ground to fuel pump relay for 2 sec and while the engine is cranking the pump is running all the time.
but pcm don't prime each time

All three of these engines a timing belt driven which means the water pump is also timing belt driven. The water pump is located behind the timing belt covers on the front of all three engines. The timing belt has to be removed in order to service the water pump. Yes coolant can leak out the pump when it is bad.

the oil pump is on the crank behind the balancer and timing chain cover:


REMOVAL

1. Remove the timing chain.
2. Remove the oil pan.
3. Remove the three (A) oil pump screen and cover bolts and the (B) oil pump screen and cover.
4. Remove the two oil pump bolts and the oil pump.

INSTALLATION

1. Clean and inspect the mating surfaces.
2. Install the oil pump and loosely install the two oil pump bolts.
3. Install the oil pump screen and cover and install the three oil pump screen and cover bolts.
4. Install the timing chains.
5. Install the oil pan.

You don't have too, but not bad idea, the timing belt drives the water pump, if you just replace timing belt, and not water pump, water pump could go out and mess up the timing belt, now it has to be done all over again, timing belt, water pump and labor.

TY for using Fixya; remember comment and rated this.

Yes the water pump does run of the timing belt system.
Directly from the service manual:

The 3.5L water pump has a die cast aluminum
housing and a plastic swept vane impeller. It bolts
directly to the right rear timing belt cover using an
O-ring for sealing. The water pump is
driven by the engine timing belt.

REMOVAL
The water pump on all models can be replaced
without discharging the air conditioning system.
WARNING: DO NOT REMOVE PRESSURE CAP
WITH THE SYSTEM HOT AND UNDER PRESSURE
BECAUSE SERIOUS BURNS FROM COOLANT CAN
OCCUR.

NOTE: It is normal for the water pump to weep a
small amount of coolant from the weep hole (black
stain on water pump body). Do not replace the
water pump if this condition exists. Replace the
water pump if a heavy deposit or a steady flow of
engine coolant is evident on water pump body from
the weep hole (shaft seal failure). Be sure to perform
a thorough analysis before replacing water
pump.

(1) Drain cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).

(2) Remove accessory drive belts (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).

NOTE: The water pump is driven by the timing belt.

(3) Remove engine timing belt (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT AND
SPROCKETS - REMOVAL).

(4) Remove water pump mounting bolts (Fig. 31).
Note position of longer bolt for proper re-installation.

(5) Remove water pump body from engine
