appropriate mixture. Even even though they are named “gaskets”, they is not going to seal your gearbox on their personal.
If every thing seems to be typical, try out changing the equipment-mesh. This is completed with the mylar “gaskets” that sit among the primary gearbox situation and the enter/output caps. Try including or taking away some of these spacers till your gears have about 1/eight”-one/four” of free of charge engage in. Pros can get replacements ($1-two) in varying thicknesses, but we recommend the quick and soiled approach of slicing your own out of a sheet of mylar.
