Bob, you have to remember you're talkin' to new guys, so when you say things like PM and TU it helps to explain at least once. PM for preventive maintenance is fairly easy, even though we also use PM for private message, but TU was new to me. Transmission Unit? about the only thing that makes sense.
Singer oil is good, but plain old 3 in 1 Oil doesn't break down or fly off as fast (just so you know I was payin' attention the last time we talked about this, Bob, you'll notice in the video I mentioned everything had been "greased, lubed and loctited, where appropriate") and a good white grease for tanks is called "Lubriplate". I use dark grease, but only because I get some super hitec stuff at work. I've done the hand spinning thing on brand new gearboxes, and I've found that to hit bearings and bushings a tube from WD40 works well. I dip it in 3in1, put my finger over the end like you do on a straw, and that transfers just enough oil to do the job, and the tube is easy to control for application.
So is that what it means to break in a gearbox? Is there a running period at certain speeds, or what?
