Draining motor oil on Type 1 engines used to be effectuated from the underside at the engine case. On Type 1 25-30hp engines by means of removing the oil sump plate, which kept also the oil screen at its place. On 1200, 1300, 1500 and 1600cc engines there is often a drain plug, that you can unscrew in order to drain the oil from the engine block without to disassemble the plate. These plates are since quite some time available as a part of the complete oil change kit # 1852 for 12/13 1600 and # 1852-1 for 25-30hp. Meanwhile we regularly receive requests to deliver this plate separately in order to replace a damaged or corroded item. From now on we can deliver it each from stock. The plates have also the drain plug and according seal for this oil sump plug.
