Dirty Distributor


Recommended Posts

Out in the glorious weather earlier when slowly the car started to become unresponsive. Nursed it home and after a few minutes diagnosing found the rotor had, basically, fallen apart. Read many items about poorly manufactured arms so I guess this is another. Having said that it may have been on the car for eleven or so years. 

Before I replace it I’d appreciate any advice on how best to clean up the resultant mess to the dizzy proper.

Thanks in advance,

just remove the base plate and strip off the parts clean with petrol or brake cleaner

fit new points and a red rotor arm

always add a squirt of engine oil down below the baseplate to keep the top spindle bush lubricated 

if there is a worn spindle the points gap will vary as it rotates  ,you can rebush lucas units  if its stuff 

a firm side push will show if its got wear play

Hi Pete,

Is there a technique to be used to remove the base plate? I’ve disconnected everything but something is retaining the plate. As I try and lift it it feels as though there is a “spring” holding it. As ever, any advice greatly appreciated.

Pleased you got it off.

Last time I did it, I bent that spring plate!

Not realising it was so low, when I replaced it all, the spring plate chewed the advance springs  :(

Had to by a 45 complete (30 quid) as there are no advance springs available, unless you know the size for the 25.

pity, the 25 is much more solid.
