Proper Assembly Lubrication

    New or serviced parts need adequate initial lubrication when the engine or
    power train is first started.

    The general rule is if it moves, lubricate it. Most mechanics simply use
    engine oil on parts as they are assembled. This provides an antifriction
    film until the driven pressure/splash oiling system circulates oil from the

    My theory is passageways are void after a rebuild and it will take a
    considerable time for oil to circulate to normal flows. New and rebuilt
    parts are rough and generate considerable friction until they are well
    broken in. Thes parts need extra lubrication for their protection. I
    suggest instead of engine oil, grease be substituted.

    Grease is simply oil suspended in various soaps to keep the oil in place.
    That is the objective, to keep oil in place until the oil pump can come up
    to speed. I recommend "pure white" grease sold in any auto parts supply
    and labeled as such. Liberally coat every part: valve stems, main and rod
    bearings, wrist pin, rings and piston grooves, gears, and essentially every
    part which has relative movement with respect to the other.

    The grease is rapidly absorbed by the oil (engine or gearbox) after it has
    done its job. Avoid moly grease and other non-pure greases as some
    contamination of the regular oil is inevitable when those exotics are

  2. Nomen Nutcase apparently has never heard of molybdenum disulfide
    "assembly lube".

  3. More nonsense from Mr. Ignorance. His theory is wrong and it can be
    easily proven that it is wrong.

    Snort! Yeah, that was my thought too when I read that nonsense. "Why
    doesn't this moron just coat his parts with assembly lube?" Uhm, it's in
    the auto parts store, ask at the counter. It's what the shop manual
    recommends using when you assemble the engine. Doh.

  5. I remember taking a two-stroke crankshaft to a motorcycle shop to have
    a new rod bearing installed in the 1960's. When I got the crank back
    the mechanic had used white lithium grease on the rod bearing.

    Maybe the mechanic was Nomen Nescio?

    I don't know when assembly lube became available, but somebody
    mentioned it to me in the 1980's when I first started degreeing my own
    camshafts. I still have the same jar of Bel Ray assembly lube. It just
    doesn't take very much of that stuff.

  6. No way. I know of no motocycle shop that would have an idiot like that
    working for them.

  7. I do. This shop even dealt with a flooded charcoal canister (California
    emissions) by stuffing grease up its overflow hole to keep the gas from
    coming out. Of course, once the fuel tank vent was largely clogged up
    that way, the motorcycle ran like crud. Maybe this was Nomen's shop?

    Clearly, you have lost your fingertip grip on reality and have descended into
    an abyss of irreversible lunacy. If ignorance were a disability, you'd get the
    full pension. Oh well, at least you only charge what your free advice is worth.
    You bring to mind a quote from Josh Billing: "Doesn't know much, but leads the
    league in nostril hair."

    You have that certain nothing. Truly, you are about as interesting as watching
    a slug move slowly across a large rock. If I had wanted to talk to somebody
    with your personality, I would be at the damn pet store talking to the lizards.
    Maybe you wouldn't come across as such a jellyfish-sucking mental midget if you
    weren't so dense that light bends around you; if your weren't so fat that a
    "Place Your Billboard Ad Here" is printed on each of your butt cheeks, or if
    you didn't have a face like a bulldog chewing a stinging nettle while taking a
    constipated dump in a heat wave. No, come to think of it, you would.

    In conclusion, why don't you go away and play Russian roulette with all
    chambers fully-loaded?
