Do not forget to re-seal the gearbox with RTV right after you have found the right blend. Even although they’re called “gaskets”, they won’t seal your gearbox on their very own.
If every thing seems normal, try modifying the equipment-mesh. This is carried out with the mylar “gaskets” that sit between the primary gearbox scenario and the input/output caps. Attempt including or removing some of these spacers until finally your gears have about one/eight”-one/four” of free of charge engage in. Experts can buy replacements ($1-two) in different thicknesses, but we advocate the swift and dirty approach of reducing your own out of a sheet of mylar.
“Groaning”, “creaking”, or “popping” all sound type-of equivalent over-the-cellphone. The best point to do is to disassemble your gearbox and take a search at the gears and bearings. The issue will usually present by itself in the way of broken/lacking gear tooth, toasted gears (like that picture on our residence webpage), or blown bearings.
