    Any particular type of lube to use on the clutch needle bearing reassembling a Husqvarna clutch?
    It just looked oily when taken apart but I wasn't sure if it wanted some type of grease. I can imagine that whatever is put in there will probably melt when the heat gets to it.

    A slight dab of anything is fine.

    I put a tiny bit of Kendall Super Blue grease on my clutch bearings, i think pretty much any kind of oil or grease will do the job.

    Thanks guys. I wasn't sure if it should be something like brake caliper grease that holds up to heat. I see that the Super Blue is intended for moderate to high heat.

    I usually use the push in grease gun that comes with the saw. Or a Oregon one. One to two pumps lubes it. I use what ever I have from chassis lube with moly in it. I never notice clutch slippage or wear.

    Not much heat is generated there.
    Mostly they get burned up due to some fiber getting wound up in there and melting.

    I know people who use their saws daily, running 5 + gallons of fuel daily, year after year. That have never greased a clutch bearing and no problems so far.

    If the clutch bearing is visible through the clutch I pump grease till I see the first sign of the grease oozing from the bearing.

    Don’t grease this bearing? Changing the crank because the roller bearings became square could be costly.

    I grease it often.

    I use chassis grease, im sure it doesn't last long. The bearings on my saws only get greased if they happen to be apart for some reason, otherwise they receive no maintenance.

    How many times have you seen that happen with a chainsaw clutch?

    Lets see, 5 gallons of fuel is 128oz x 5 = 640oz of fuel.

    A 461(common production saw) has a 27oz fuel tank.

    640oz / 27oz = just shy of 24 tanks of fuel. So, they would be working 12 hours a day and averaging a half hour per tank of fuel. Even if I were bucking logs into firewood for 12 hours I don't think I could go through 24 tanks of fuel in a day.

    Those are some tough men you know.

    Risk analysis.

    Chance of occurrence is extremely low.
    Cost of occurrence is extremely high...most people would just buy a new saw if they torched the crank on a modern saw
    Cost of maintenance to avoid the risk? Extremely low.

    I'll keep on greasing my bearing.

    So, tree service running 4-5 saws would only be working 2-3 hours. And yes they do lot clearing.

    Agree, but my question was have you ever seen one ruin a crank? I take it you have not.

    I see, thought you were talking about a single guy running through 5 gals of fuel in a day...which seemed like a lot to me.

    Or a couple drops of 10W30 from an oil can, all my saws ever got since 1962 til present. Never seen a needle bearing go unless left full of water.
