7.6.2 Distributor Case & Distributor Mounts
Figure 148
– Installation of Seals & Assembly
Fresh seals must be fitted to the case and to the distributor mounts as shown in Figure 148. Note that
later engines use a larger crankshaft timing gear and a thinner oil seal to suit. Oil seal size must be
matched to fit the gear used.
These seals must be well lubricated using grease for assembly
– this part of the engine tends to run
slightly dry and generous lubrication now will greatly reduce wear of these parts.
The distributor posts, shafts and mount plates can be fitted to the distributor case now. Loctite 515
sealant is used on all mating surfaces.
Glue the distributor rotors to the shafts using 5-minute Araldite mixed with a suitable filler (such as
cotton flock) as shown in Figure 149.
New bushes must be fitted to the distributor housings as shown in Figure 149. Distributor posts must
be generously lubricated with Nulon L90 or grease.
If the distributor shaft has been replaced it will be necessary to rivet the drive gear to the new shaft as
shown in Figure 150
. 3/16” stainless steel (Monel) blind rivets must be used. Ensure that the heads of
the rivet do not get caught on the edge of the shaft and that the tails are not so long that they project
past the shoulder of the shaft. Also ensure that the remainder of the rivet tails are driven out of the rivet
– otherwise they can work loose in service and damage the engine.
