Removing
Disconnect the earth cable from the battery.
Pull out the green wire plug on the distributor, having previously disconnected the retaining bar.
Remove the distributor cap by loosening the 2 fixing hooks. Insert a screwdriver into the cross slot of the hook, press down and turn 90' to the left (quarter turn). The hook will be unhooked from the mounting lug fixed on the side of the distributor.
Disconnect the vacuum connection from the pipe.
Set the engine to the TDC position of the 1st cylinder. To do this, place the gearbox in neutral position and turn the engine with a wrench on the central nut of the crankshaft pulley in the direction of rotation (clockwise) until the marking on the contact tongue of the distributor rotor matches the mark on the edge of the distributor housing; if present, move the dust cover.
At the same time, the pointer on the block body should be opposite the TDC mark on the crankshaft pulley (see arrow).
Attention: Do not turn the motor in the opposite direction.
Loosen the fixing bolt of the distributor using a socket wrench and remove the distributor.
Attention: Do not crank the engine with the distributor removed.
Installation
Before installation, check whether the engine is still at TDC position of the first cylinder. A Rotate the distributor shaft so that the markings on the distributor rotor and the distributor housing match.
Insert the distributor so that the elongated hole on the distributor base is approximately in the middle of the hole for the fixing bolt.
Tighten the fixing bolt without tightening.
Temporarily set the ignition timing. To do this, connect a stroboscope according to its instruction manual. Have an assistant turn the engine over with the starter and illuminate the ignition timing marking on the engine block with a strobe light.
The ignition timing is set correctly when the setting value on the crankshaft pulley is stationary against the pointer on the engine block and ignition timing table.
If the desired value is not reached, then loosen the distributor fixing bolt and turn the distributor until the markings match.
Tighten the distributor retaining bolt. g Tighten the vacuum connection.
Check the seating position of the dust cover, the spout of the cover must be inserted into the groove on the edge of the distributor body.
Check the vertical seating of the fixing plate on the distributor housing, align and tighten the bolt if necessary.
Insert the distributor cap so that the wire for the first cylinder is opposite the notch on the edge of the distributor. The notch is only visible when the dust cover is moved slightly. On top of the cover of the distributor next to the corresponding connection point of the high-voltage wire is the designation "1" in a circle.
Check the correct seating of the distributor cap by turning it to the right - to the left; the lid must not turn. Push down the 2 side locking hooks, aim by turning at the locking plate on the side of the distributor housing and release.
Check that the hooks are hooked correctly and that the distributor cap is firmly seated on the distributor.
Insert the green wire into the distributor and secure with a plate.
Connect the negative cable to the battery.
Start the engine and warm it up.
Set the ignition timing with the engine running and check the angle of the closed state of the contacts.
