Cannot find anywhere to fill the gearbox oil on this model. Your "changing gearbox oil" article says there is a plug similar to the drain-plug towards front of gearbox - not so on my engine. Can I "release" the speedo cable assembly that appears to be held on the top of gearbox by one screw, edge it up/aside, and shove a tube in, fill there ? There is also a strange little bent tube with a "cap" on it, but the tube inside is very narrow - what is that ? Can I fill through that ?
