Distributor swap

After a disastrous journey home from work the other day in which the accelerator cable snapped (solved by a quick walk to a nearby Halfords for a bicycle brake cable) and the ignition packed in, I have decided to replace the distributor and electronic ignition (The ignition has always been of the electronic type since I have owned the car but I have no idea how old the distributor unit is)

The new unit is an autospark type that is available from all the major Morris Minor suppliers such as ESM.

Looking back now, fitting the distributor is an incredibly easy job that should’ve only taken a few minutes, however it took me a number of hours, as I could’ve sworn there was something I was missing – no matter how hard I tried I couldn’t seem to drive the distributor all the way into the hole in the engine block. I could feel that the driving dog/peg was aligned the correct way around inside the block, but I could not find any way to push it in the last few millimetres.

Note how the distributor isn’t pushed all the way in so that the flange edge is flush with the clamp.

For a while I even considered that I might’ve purchased the incorrect distributor, but the actual problem was something easily solved; The clamping plate that locks the distributor in position had been over-tightened and bent at some point, not leaving a large enough hole for the distributor unit to be fitted into.

In this image it suddenly becomes quite apparent as to why the distributor hasn’t been fitting correctly – see how bent the top of the clamping plate has become from being over-tightened in the past!

Please ignore the large quantities of oil and grime around this part of the engine – For the sake of the wallet it’s best ignored.
