Rob Salisbury Posted May 27, 2020 Report Share Posted May 27, 2020 Well, starting from the input shaft shaft the drive goes little cog, big cog, along the layshaft, then little cog, big cog so there are plenty of teeth to nash and mesh, and 1st gear is straight cut, so it's never going to be quiet like a modern box, a bit winey especially on over run but any undue noise is likely to be from the layshaft bearings or the mainshaft bearing that the 1st/reverse cog runs on. If ,when in neutral there's a noise a bit like a load of ball bearings sloshing around then it's time to look at the layshaft. Cheers Rob Quote Link to post Share on other sites

Roger Hi Roger! I hate to say this! Have you been caught out by one of those soft layshafts from Sunbury? In my experience a nosy whine in the first 3 gears is always the hardness worn away on the layshaft? Does it whine in the other 2 gears then go away in 4th when it is direct drive through the gear box? Have you seen any signs of white froth in the gear box oil if you have been using ordinary engine oil as that is a sign that the Hypoid Gears are braking down the oil in the gear box and cause oil starvation in certain areas of the gearbox?

RogerH Posted May 27, 2020 Author Report Share Posted May 27, 2020 Hi Chaps, thanks for your input. It sounds like the lay shaft. All being sorted. Roger Quote Link to post Share on other sites
