Assembling a Lucas 25D distributor (Morris Minor) + Points

This video is a guide on assembling a Lucas 25D distributor and how to set the point gap. I am not a professional or an expert, so please use this guide at your own risk. This is what I did and what I learnt on the way when I took apart a Lucas 25D for inspection and cleaning before reassembling it into a spare points unit for my Minor.

Great video, thanks. I’ve just bought an engine that’s been sat in a shed for donkeys years. It’s from a herald 13/60 to replace the horrid longer stroke 1500 in my mg midget.

It came with a very poorly looking 25d4. Most bits cleaned up ok but the cam was seized to the shaft, weights stuck, etc. I’ve got it apart eventually but with significant damage. I will have to make a new plate and spring hangers etc for the bottom of the cam if I ever want to use it. Probably not
Worth all of the effort I’ve gone to because it took me a day to find your video and realise the vacuum unit is missing ! I thought it was centrifugal only at first!

Oh well, it’s been fun messing around with and a learning experience!

The easiest way to put the centrifugal weights is, put the weights on the distributor cam, then turn distributor upside down and place cam onto spindle . That’s how I taught hundreds of students in my Technical College motor vehicle classes, City & Guilds courses. It saves trying to get the pegs on the cam to line up with the holes in the weights. Give it a try, hope it helps.

Very timely as I'm just refurbishing the 25D distributor in my Sprite! Thank you.

Very cool. I bought a 1959 MM last week

Thank you for sharing your knowledge, it's a big help for me!!

Very helpful thank you.
I bought a chinese knock-off 25D (my car came without a distributor so no core). Gonna tare it down and make sure everything moves properly.

The vacuum advance wheel, is that an actual adjustment? Or do you just turn it until it clicks? Distributor is going in the car tonight. I will let you know how it runs with the dizzy on it. The powerspark had a wire jamming up the vacuum advance mechanism (wire was wedged tight up against the distributor cap) came with zero lube on anything and arrived with the points not lining up and also having a very large gap. Once these easily fixable things are addressed it looks ok.
