Oil circulation reservoirs;
On the first 350cc moteurs (Single cylinder, enclosed side valves, 346.7cm3, 4 stroke, 7hp (cv)) used on the C7 range from 1931/2 to 34 – the B4L model. There was initially a oil reservoir attached to the inspection hatch, positioned top back, of the moteur. This was a tall cylinder of 27.2 cms high by 13 cms in circumference and held approx. 2/3 litre of engine oil. See left-hand photo.
There was later changes to the dimensions of the cylinder (27.5 cms tall x 21 cms circumference) and located in a slightly different position and larger capacity than its predecessor – attached to the very rear right side of the moteur. Thus not impeding the access to the moteur and requiring less pressure to fill. Photo 2
Here is a example of a very rare Energic B5L oil reservoir/circulation system;
Energic B5L oil reservoir/circulation.
This all changed with the new Motobecane engine of 1934 the S bloc. Circulation of the oil was increased and the reservoir was now a separate tank next to the fuel tank. It offered greater volume of oil , a genuine cooling system with re circulation of oil to the reservoir and a evacuation to the drive chain for over capacity in the reservoir or greater pressure relief. It was also able to lubricate with a fine pressured mist of oil the drive chain.
