[QUOTE="1660bob, post: 53788, member: 366"] Hi All, took my N.O.S. (2007) Alton apart today to look at swapping grease for oil. It was well packed with grease, but even so once pushed out of the way of the gears,pretty redundant. I could not see any reason to "stone" the steel gears, they seem OK to me, but I noticed that the main input gear is not the same as the one in the picture of the failed unit in MPH/Whitakerpedia.That one has a deep recessed face, whereas mine is flat,pressed onto the shaft and stamped: M1 x 38, and 4654. Perhaps Alton changed the gears for better finished items.......Looking at the drive end casing from the outside, the drive passes through an alloy circular boss which seems to be pressed into the end casing? This boss prevents the complete removal of two of the three through bolts that hold the main casings together, there is enough room to undo them to seperate the cases, they just remain captive in their respective holes due to the edge of the said boss partially covering them. I would have liked to remove them to perhaps insert fibre washers under the heads to prevent oil seepage. Does anyone know how to remove the alloy boss? There must be a bearing behind it, or behind the input gear,accessed from inside the casing. I can only assume the input gear/shaft press out as one and are removed from inside the case?
