Reply To: Steel bush set flywheel-gear ring 15CV modification

Mark,

Yes, you have an early flywheel without the silentbloc bushes so the kit you have is redundant.

The exposed flywheel means there is nothing to insulate the clatter when the starter motor engages with the ring.  My understanding is that the silentblocs were only added to reduce that noise which was perceived as unfitting for a luxury model car like the 15/6 or Big 6.

In my opinion, the mod was not one of Citroën’s cleverest upgrades.  Having heard vehicles with and without silentblocs fitted being started, I dont think the difference in noise level is significant enough to warrant the change.  On the other hand, the trouble they can cause when/if they do fail certainly detracts from any small noise advantage they may offer.

As I said, had my engine been out I would happily have fitted the older ringgear I have “in stock” and no silentblocs but I am confident that the parts I now have are very good quality and I anticipate they will therefore be good for some time.  However, should they  disintegrate before the engine needs to come out, I shall not hesitate to replace them next time with solid bushes like the kit you now have in your stock!  With that in mind, I had already drawn up my idea of what was needed in anticipation of having to have some made locally …. but I may now contract you if I do ever need some!
