Today was one for doing the first three of five Injection pump settings using the Peugeot-Fenwick factory tool kit.
Step 1: Not a great view, but the tool you see sticking up by Cylinder 4 has a hook on the other end that sticks into the richness lever and locks into a slot on the injection pump body:
Step 2: The first pre-adjustment is to the clearance between the throttle body and the throttle body drum: 1 mm (adjusted by a 5 mm Allen key as you can see) with a special tool inserted into the throttle body and the tool shown above in Step 1 still in place:
Step 3: In this step - Adjustment I (the precursor to Adjustments II and III of course!) with the injection pump richness lever locked in position and the throttle butterfly also locked in place, the two bolts (with jagged lockwashers) holding the thin metal "sector" plate to the throttle drum are slackened and it's moved until the forward flat mark lines up with the boss on the throttle body, then the bolts are tightened down again.
Step 4: Another view of the special tool that locks the injection pump richness lever into a slot on the pump body while the throttle position is set by another tool:
Step 5: Inside the throttle body is the tool that holds the throttle plate in a set position relative to the injection pump, which also has a special tool in it (the top of which is visible at the bottom of the photo). This essentially registers the throttle body position with that of the injection pump:
Step 6: Adjustment II: this is the maximum throttle opening (you can see the vertical throttle plate in the photo), and it's set by lining up the notch on the thin metal plate that's bolted to the throttle drum with the jagged lockwasher with the front face of the boss on the throttle body. The adjustment is achieved by rotating the screw whose threading you can see just above the cable.
Step 7: Final check (Adjustment III): Minimum throttle opening. Here the higher notch on the thin plate bolted to the throttle drum must line up with the flat boss on the throttle body. Lower centre right of the photo. You adjust it by adjusting the minimum throttle stop screw. Once the engine's running, the adjustment can range between where it is in this photo (12°) and the lower notch to the left (10°).
Step 8: put air filter etc back on. Battery cables are ready to be connected:
The last two adjustments of the injection system are done with the engine running - basically, the thermostatic richness lever on the intake manifold is set at 60°C by adjusting a screw (more special tools!) and also adjusting the supplementary air valve at the same time.
