7.8.6 Distributor drives
Figure 169
– Fitting Distributor Case & Setting Timing
Ensure distributor shafts are generously lubricated before assembly.
Apply Loctite 515 sealant to the gear case as shown in Figure 169.
Rotate the engine to 25° before TDC on the compression stroke (indicated by the cam and crankshaft
timing marks lining up) as shown in Figure 169.
Both distributor rotors must point to the timing mark engraved on the distributor mount plate
– use a
ruler to check that they are nearly parallel as shown in Figure 170. They will not be exactly parallel but
they should be close
– and provided the timing mark lines up with the tip of the cap it will work properly.
The gear case can now be tightened onto the engine mount plate to the torque specified in Table 9.
Note that certain 3300 engines (See Section 13 for serial number information) have different flywheel
starfish. These parts have been indexed to give 20° or 23° BTDC for spark timing instead of the original
25°. These are
engraved with “20° BTDC” or “23° BTDC” as appropriate. When using this part the
timing procedure given herein must be adjusted to suit.
