افتراضي rough translation description

Below is a rough translation description of a rebuild of a renault 1.6L diesel injection pump. I can't read French, if you can,

Add the center spring


Then the disc cover with cams goes over it all.



To assemble this part, the feed pin of the piston (green reference mark) must be aligned with the key.

The cams (bumps) of this disc while passing on the rollers is what moves the piston and compresses the fuel and the injection. The original author had swapped the disc from another model car with a slightly different cam profile.

now, let us move to the piston distributor:

then the drawer of regulation:

This ring, directly actuated by the regulator, will more or less, cover the exhaust hole of the piston (located in the previous photo). During the injection, cam moves, moving the piston. According to the position of the regulator, the hole is released by the depression of the piston. This controls the proportioning of the amount of fuel injected. (when the hole is open, the pressure is released and the injection stops)
The piston is known as the distributor because during rotation, via the holes, it directs the fuel towards one or the other of the exits of the pump.

Reassemble the piston distributor:

then return springs:


The end spring holder at the end of the piston:


and one puts the whole at his place in the pump:


Now reassemble the regulator levers and their return springs

the difficult part of this is due to the position of springs:


Close up of the articulation of the levers by special bolts (custom to the modifications by the original author)

installation of these bolts with their new aluminum joint

"Y' has more than A returns the whole of the levers speaks high" (couldn't translate this part)

The piston distributor (exhaust port marked w/green arrow), the opening for the injectors (red), and the 4 grooves for filling the chamber (green circle).

All the return springs in place

More than has to position back the whole, then the redémonter still one or twice because the return springs of the piston did not fall opposite, and veiled: (couldn't translate this part)


All the pieces of the centrifugal governor.

The pieces of the masselotes.


Placed into the body of the regulator.

Replace the sleeve of the regulator (notice the gauged hole to modify the beginning of injection according to the load):


Alignment of the axis of the regulator in the pump housing

The spacers which go behind the rotor of the regulator.


Then the regulator.


Then tighten the axis using a key. Use this special wrench to counter hold the axis during tightening. The position of this axis is important, because it regulates the the beginning of injection according to vacuum load. Therefore, you must have marked it during disassembly to get the same alignment.

Removal of the lever bushing


A new bushing

Securing the bushing with a bolt and washer


The control shaft and the regulator springs

The flat part (green) is engaged in the notch of the lever (red)

Put back the lid (with its new joint) and screw it in place.
Reassemble the stick control, note the exact position before disassembly.


The regulator valve and new components


The fuel shut off solenoid


And finally the main shaft front seal, you have to gently press it in with a drift or socket.


Finally assembled.
