    1/8" Zerk Fitting Tab

    NPT is National Pipe Thread as compared to SAE or Metric threads. Needless to say they are different so the hole must fit the fitting. Or the reverse:)

    Changing from DC motor to an AC motor.

    Many interesting ideas..Make sure the AC motor is reversible, you might want to lower the load!

    Why can't an internal combustion engine self-start from zero rpm without being spun-up by a starter?

    Normally a four stroke engine uses CARBURATION, COMPRESSION, , IGNITION, EXPANSION. Compression is missing and any fuel will condense.

    Twin Engine V12 or 2x60°V6

    Might Google GMC V12 which had one piece block and crank, the rest from the V6

    GM 4x4 front axle actuator

    My 99 turbo diesel transfer case has a clutch similar to an AC clutch that gets the front driveshaft spinning before the thermal front axle engages. Thermal unit burned out long ago and is now a manual operation and being in four low without front axle engaged makes for better sharp turns...

    Two-stroke cycle engine

    Ooops!!! I stand corrected.

    Axle wind up: may it damage the driveline?

    U-joints are not as strong when run at angle and the slip joint may not have enough travel and push too far into the transmission.

    Two-stroke cycle engine

    The 2,4 8- 71 diesels need blower intake. They are basically two stroke with cylinder ports for exhaust and poppet valve for intake in the head. As the piston reaches bottom of stroke it uncovers the exhaust port and shortly after the intake poppet valve opens pushing the exhaust gases out then...

    Why can't diesels rev as high as spark ignition engines?

    My 82 Isuzu I mark 1800 cc diesel could turn 5500 rpm with lots of black smoke:)

    Miller timing vs F timing

    I would ass-u-me that since Miller timing uses variable valve timing that f-timing would be Fixed timing. :)

    rod/stroke question

    Almost everything in life is a compromise and conrod length is no exception. Longer = more time trying to push the crank out the bottom---shorter = more time trying to push the piston through the cylinder wall. :)

    Will transverse engine mounting counteract wheelstand in a hi-power bike or dragster?

    Since the lowest point of the vehicle is the ground and everything else is above the ground, the weight shift will occur. Front wheel drive included. Engine rotation may try to bend the frame but weight transfer will still occur.

    Heavy Duty Diesel Head Gasket Failure

    To me the photo of the gasket suggests that it was damaged either prior or during installation. The clamped surface looks straight but the gasket is pushed out at the rear as if it were hanging on a nail and pulled off. Suggestion: Cut the heads off the old studs/bolts and use them as guide pins...

    Pinion Depth Shimming

    It is much cheaper to take a little too much from the pinion gear housing and shim the pinion than to get it 'just right' and not be able to use a given pinion gear set. Now where did I leave that tube of prussian blue?

    Cam Chain Noise

    I would disagree with BigClive - I think it would take considerably more effort to open the exhaust valve throttle open than throttle closed.

    Floating bearings

    Some aircraft engines, Allison and Merlin come to mind and used floating bearings with a bifucated rod and a narrow one in the middle and each rod used the full width of the crankpin. I think Harley V twins also use this arrangement, and the inserts are quite thick, not the thin inserts.

    chevy v8 of the 70s thrust bearing load/time adequacy

    I believe that any automatic with a torque converter will put a forward thrust on the crank while the engine is running (front wheed drive excepted.) The oil pressure inside the converter is trying to push it off.

    Measuring rotating Force

    I will try to put the picture in my mind into this keyboard. The main driveshaft for the hone will have a spring loaded inner shaft that will deflect a given amount for the load of turning the hone. Attach a set of points and condenser, with a coil and fire a timing light with each turn and...

    transfer case: no option of engaging 4 X 2 (low speed mode)

    The easiest way is to not lock the front hubs or axle. Why? Sometimes you want to go slow over rocks etc. and turn sharply when traction is good. No mention of the transfer case type or axle type complicates the answer but I hope it helps. The fact that you do have 4x2 in high range tells me you...

    Variable displacement oil pump

    If I remember correctly the SlimJim Hydromatic had a variable displacement pump.
