How do I set injection pump timing


you haven't given which make , model,year of engine type of fuel pump, make of fuel pump and the only clue is the flywheel
the injection timing mark is normally denoted as a lightning symbol and you will find it anywhere between 14 degrees btdc to 22 degrees btdc
or it will be set at the degrees btdc r recommended by the manufacturer
It has to be exact because after that mark will be down on power and too far advanced will melt pistons

How i set the timing of injection pump rotary of isuzu 4hf1


what year is the vehicle as if its common rail injection system then it doesnt matter what position its in ,its a just a pump ,but if vehicle is older than a 2000 or so then its a proper injection pump and on the front of the pump in the gearwheel is a 8mm hole in one of the flanges and this has to line up with a hole in the block and you peg it with a 8mm drill bit .

A Isuzu NPR 4hf1 rotary pump timing marks set


Hi. If it has a rotary pump, the pump needs to be installed with the crank at 49 deg BTDC on the compression stroke cyl 1. Mark dot gear on pump with white paint. Line up dot gear on pump with line on pump bracket and install. Remove PRM sensor from bell housing and check if line on pump gear is still lined up with line on pump bracket.

2000 dodge ram diesel 2500 . What is a fuel injection pump mechnical failure? a fuel valve feedback circuit?


This usually happens when the lift pump gets worn and fuel pressure drops below 7lbs and the injection pump has to work harder by pulling in the fuel and will destroy the pump,your is probably a vp44 fuel injection pump it needs replaced and they are expensive 1200.00+ but also change the lift pump or change to a fass fuel system,if the lift pump went out and you replace the injection pump it will ruin it in a short time.
The injection pump is not an easy job to change or for a novice mechanic as it has to be set in time with the engine at top dead center,and then the whole fuel system needs to be bleed of air.

How do i retime diesel pump after belt snapped


YOU HAVE TO RETIME BY REMOVE AIR CLEANER.REMOVE CYLINDER HEAD COVER.AND TIMING BELT COVER.TURN THE ENGINE TO TDC OF THE NUMBER 1 CYLINDER HEAD.YOU NEED TO INSERT A SETTING BAR INTO THE SLOT ON THE REAR OF THE CAMSHAFT.VW TOOL 2065A OR EQUIVALENT TO HOLD CAMSHAFT IN PLACE.WHEN YOU RETIME THE INJECTION PUMP YOU HAVE A PIN ALIGNMENT SLOT ON THE SPROCKET HUB IT SHOULD BE AT 12 OCLOCK POSITION.YOU HAVE TO INSERT LOCK PIN TO HOLD SPROCKET IN PLACE.WHEN YOU INSTALL THE TIMING BELT.YOU HAVE TO PRIME THE INJECTION PUMP.BY HOOKING A HAND HELD VACUUM PUMP TO THE RETURN LINE FITTING AND DRAW FUEL INTO THE INJECTION PUMP TO KEEP FROM DAMAGING PUMP IF PUMP IS DRY.THIS WILL GET VAN GOING BUT THE DEALERSHIP STILL HAS TO RETIME TO INJECTION PUMP USING A SCANNER.IF VAN DONT CRANK BROKEN BELT COULD HAVE DAMAGED THE VALVES AND PISTON.

Remove and install diesel fuel injector


First, keep everything as clean as possible. Contamination below 30 microns, which cannot be seen by humans, can destory a diesel fuel injection system. Clean everything off anything having to do with connections on the fuel system and cover any connections left open.

Begin by removing the intake manifold. This will remove the clips holding the injection lines passing underneath and around the intake runners. After removing the manifold, cover the openings in the cylinder head (I use wadded-up paper towels).

Next, remove the clips at the brackets on the injection lines closer to the injectors.

Loosen all of the injection connections at the injectors. Do not remove the lines.

You can remove the water crossover tube if it is in your way, but drain about a 1/2 gallon of coolant before your remove the crossover.

Remove the oil fill tube from the timing cover. Turn the engine clockwise, using a 15/16" socket and ratchet (or breaker bar) on the center bolt of the crankshaft. As you turn the engine over, a bolt will show up at the opening where the oil fill tube was removed. Remover the bolt and keep turning the engine over until you have removed all three bolts. Do NOT use the starter to turn the engine over and, after removing the third bolt, do NOT turn the crankshaft any more.

On top of the timing cover, behind the rounded top, is the place where the injection pump is bolted to the cover from the back side. Clean the top of the timing cover where it meets the injection pump and look for a thin line scribed into the cover and one on the injection pump. Note the position of the two lines (they are usually aligned) for reassembly.

Remove the throttle cable assembly from the injection pump. Remove all the wires from the pump and note which connection the big pink wire goes to. The other wires will be green. Remove the return hose at the top of the injection pump.

There are three nuts holding the injection pump to the timing cover and you will need a 15mm socket and/or wrench to remove them. When you do, the injection pump and injection lines can be removed as a unit. Note the position of the driveshaft of the injection pump to set the new one the same way. If you are not going to put things back together right away, cut up a plastic garbage bag and make covers for the injectors. Secure the covers with rubber bands or nylon cable ties to keep dirt out of the injectors.

Carefully transfer the injection lines to the new pump. It is possible to cross them up so pay close attention while moving the lines. Transfer the fuel inlet pipe to the new pump and whatever device is mounted on the passenger side of the old injection pump to the new pump.

Get a new injection pump to timing cover gasket and install it over the timing cover studs. Install the new injection pump after setting the driveshaft to match the holes in the gear inside the timing cover. The pump can only be installed one way since it is indexed to the gear. Reinstall the nuts on the studs and set the timing marks to the same position they were when you removed the old injection pump (the lines on top of the timing cover and the flange of the injection pump). Tighten the mounting nuts. Make sure that all the injection lines line up at their injectors, but do not tighten the connections at the injectors yet.

Put the first bolt back into the gear through the oil fill tube hole. Hand tighten it and then turn the crankshaft clockwise as before to install the remaining two bolts. Then, tighten all the bolts securely and resinstall the oil fill tube. Reinstall the throttle connections on the injection pump.

Install a new piece of 1/4" fuel line from the fuel filter to the injection pump (the old one is usuall brittle since it never gets changed). Remove the covers over the opening in the cylinders heads and reinstall the intake manifold using new gaskets.

Reinstall all the injection line clips that were removed and the coolant crossover tube (if you removed it and don't forget to add coolant to the radiator). Reconnect all the wiring on the injection pump, except for the big pink wire. Install a piece of clear tubing on the top of the injection pump and connect it to the return tee in front of it (where you removed the rubber hose from the old injection pump).

Now comes the fun part: Disconnect the glow plug relay connector (two small wires in a connector) from the middle of the relay. The relay is usually on the driver's fender and close to the battery.

Crank the engine, in short bursts, until you see fuel in the clear tubing on top of the injection pump. When you do, reconnect the big pink wire on the injection pump. Continue to crank the engine in short bursts (allowing the starter to rest between cranking cycles) until you see fuel dripping out of the injection lines at the injectors. When you do, tighten the connections where fuel is dripping. When all lines have been tightened, reconnect the glow plug relay connector. Remove the clear tubing on top of the injection pump and reinstall the fuel line that was removed from that location.

Then, try starting the engine normally. If it will not start, try some WD-40 down the intake. You can use ether, but you MUST disable the glow plugs be removing the connector at the relay.

The engine may run rough or stall at first but it should smooth out after all the remaining air comes out of the system.

Torque values are as follows:

Intake manifold: 25-37 ft-lbs
Gear bolts: 13-20 ft-lbs
Injection pump mounting nuts: 25-37 ft-lbs
Injection lines: 15-24 ft-lbs ("wrench tight" is fine)
Injection pump fuel inlet fitting: 15-20 ft-lbs
