Too much choice

Darracq brake lever

Top hole or Bottom hole that is the question

Fred Deusenberg originated hydraulic brakes on his 1914 racing cars, so says Wikipedia. Unfortunately Louis Coatalen had other things on his mind so stuck with mechanical brakes in 1925.  He also had so little faith in those new fangled front brakes that they are smaller the rears.

As you can see from the picture I have choices, this is the link from the brake pedal to a relay lever.  Under hard braking the pedal would hit the floor so I had to pick the top hole giving me less leverage.  There is another like this with 3 choices for the rear brakes, given that the rear brakes are 100mm larger should they be given more or less leverage?

Dismantle and Pack

Yesterday I spent the good part of an hour making a tool that I used for 10 seconds. I needed a 1 ½”AF deep socket to remove the flywheel nut, luckily I had a spare ¾” drive Chinese one that was made of such crap metal that I could easily turn the square drive into a circle, then added a bit of gal pipe and a spare ½” drive socket for the top add some dodgy welds, the rattle gun and as I said the job was done in 10 seconds….at least I can use it to put it back on later. I will throw it in the box labeled “Special Tools”. However it will not stop me making one just same when I need to do this job again, I always forget to look in that box!

Having had this engine apart a couple of times now means it came apart very easily this time , whacking the flywheels with the copper mallet freed it from the crankshaft and later the big-end journal from the inner flywheel. This engine has effectively 3 flywheels and the ones inside are heavier than the one you can see in the pictureSizaire Engine dissmantled, in fact the engine looks like it should run on steam by the robustness of construction and therefore weight. The reason I have dismantled it into its component parts is so I can carry it. Never mind shaggers back this thing will hurt much more without the fun angle.

So today I have dropped the bits off and await Colin’s call so will have to pull something else apart while I wait.

Sizaire Engine Out Final

Sizaire Naudin EngineAs can be seen, the engine is out although for a while there I had a bit of a déjà vu moment as originally the crane was at the front of the car, it took the strain so I knocked out the last bolts supporting the engine then realised that I was dropping the engine to the floor not lifting it but the crane could not go down as the radiator was in the way. Not quite as bad as the SM oil change fiasco.

Nothing like the right tools for the job, the engine is now resting on one of the ramps of the hoist jacked up to beSizaire Naudin Engine Flywheelnch height, hydraulics really are wonderful. Next problem is getting the 38mm nut holding the flywheel off, a deep socket and an impact wrench would be good so I may have to sacrifice one of my Chinese 3/4″ drive  sockets to the angle grinder and welding gods.
