3.9 Distributor Parts & Pieces

[Jamilton]

Hello all,

Picture below is the plastic piece that goes on the bottom of the distributor shaft between the fly weights. Mine is broken. See the little pins beside it- also the main ring has cracked in half where the pins have broken off!

My question is; what is it for and do I need it in order to reliably run?

Thanks a bunch,

On the basis that it was put in there for a reason (though I have no idea what either to be honest) I would say probably yes and the weights may not centrifuge properly without it (whatever it does!!).

Next question is are they available on their own? I think the bit in question is RTC3198 for 3.5L engines with Dizzy 35DM8, RTC5090 with Dizzy 35DLM8 and RTC5090 for 3.9L and 4.2L engines. Not cheap though - they were about £70 or $140US in the UK last year for a 5090. Current Roversnorth price is $139 so not a bad guess!

Happy new year

Paul

Thanks Paul.

I think I'm gonna try to run without the little bush and see how she does. If she won't run good then it's Mallory time.

Regards and Happy New Year!
