Don.
Your Skizzenbuch is increasing in volume yet there are further items to consider worth while to be included.
The VIICs are equipped with possibly one of modern technology`s last and most advanced use of mechanical transmissions. Hundreds of links, rods , traveling nuts, bearings and bevelgears installed required a substantial maintenance for safe operation. Greasing and lubrication is one of the major factors. The greasing system consist of two major greasepumps with container, one A situated in the engineroom stb aft side next to the main engine clutch handle, the other B, in the forward torpedo compartment stb side just aft of the torpedotubes ( next to the visitor door on museum U 995). From these grease pumps pipes goes via a hullcock through the pressurehull to a selector/distributor and then to various difficult spots outside the pressurehull. The outboard selector is controlled by a handle inside the pressurehull as can be seen on my sketch below. Please note the details on the construction are assumptions from my side as no drawings are available.
Further to the system are grease cups practically fitted everywhere there are moving parts, travelling nuts would have a flexible grease hose as can be seen on the Kingstons on plate 28. Most of these Kingston greasing spots are fed by greasecups in the control room. Many of the grease cups of the museums U 995 are gone, only some pipes and under parts of the grease cups remains.
The system was extensive and labour consuming and we had a PO responsible for the weekly greasing routines.
