Weird looking Lucas Rotor

[Tony]

I am trying to find a replacement rotor for my '93 Super Sprint.

 

The Lucas distributor is engraved 103 FXYULS 11/90. It is not vacuum advanced.

The Lucas cap is marked 54400270.

The Lucas rotor is marked 517 2191.

 

The rotor is a flat disk with a slotted cup underneath that fits down into a Hall sensor (I think). The slotted cup is loose.....

 

I have searched relentlessly for the rotor and have found no reference anywhere about it. Everything I've seen seems to have points and a simple small rotor. Not sure if the distributor I have has been modified away from points, but the rotor is marked Lucas. Really would prefer to find replacement parts; don't really want to replace the entire distributor.

 

I have a bunch of inquiries out to various suppliers, but if any of the above rings a bell, I'd love to hear from you.

 

Thanks again.

A picture would probably help. But for what it's worth, most (all?) of the xflow distributors supplied by Caterham with their kits/cars came from Aldon and were based on Lucas (or sometimes Bosch) distributors. The number scribed on the housing is an Aldon number that signifies it's for a xflow, has side-exit cap, no vacuum advance, and is nominally curved for unleaded fuel (though consensus on BlatChat is that it is a lousy curve):

But, from what I know (and on my car) the rotor itself is the standard part for the donor distributor (in my case a Lucas 45D, rotor P/N DRB104, IIRC).

 

Though, as you say, perhaps someone has modified the guts in yours if your rotor looks different.

 

Hope that helps.

Here are two photos. The slotted cup under the rotor is loose, can't be good for the timing............

The manual says it is a "Caterham distributor with optional Lucas electronic ignition".

Aaaaaargh. Last two hours reading the Tech Blatchat's back to 2000 told me the bad news. Said rotor no longer available. Unreliable as well. Although I could probably epoxy the "skirt" to the rotor (which happens to be loose now), might be time to consider other options such as alternate electronic ignition systems.

 

Anyone done this transformation? Curious about wiring, i.e., need to get into the wiring harness? Remove Caterham electronic ignition? Most straight forward swap you might recommend? Might be time to just deal with instead of waiting for it to crash...........

 

Thanks all.

Tony - I won't bore you with my distributor story, but I ended up having it refurbished and recurved by Advanced Distributors:

I'm pretty sure he (it's a one man operation - can't think of his name off the top of my head) can install a Pertronix ignitor in the distributor. I'd give him a call and discuss your distributor and situation.

His name is Jeff Schlemmer and he's very well regarded in the MG forum that I visit.
