    Its that time of year. Lets discuss ether.

    "Jim D> your beating a dead horse.. Your trying to explain how ether wont break a piston or rings to people who collectively, have 1000 years experience FIXING THIS PROBLEM, seriously?" Yes, very seriously. What is the physical means by which ether breaks piston rings? Pre-ignition detonation...

    Its that time of year. Lets discuss ether.

    For reference, the broken "piston rings" that I am referring to are those in the photo that Doyle posted, bottom of page 5 of this thread. One ring in the photo is broken into eight pieces. For a dished combustion chamber piston, the top piston ring is 3/4 or 1 inch below the top of the...

    Ok. So how does ether break rings? Only thing Mr Vogt said was that "... you have a recipe for damage." (Dragster engines run on *nitro methane!*, and they don't break piston rings...)

    No. Those piston rings broke because the engine over-reved. Remember the piston ring ridge at the top of an iron cylinder: If a old chevy six grocery getter never spun more than 3000 revs, ever in its life, and the cylinder ring ridge developed over years, from the "plucking" of the ring and...

    Its that time of year. Lets discuss ether.

    I'm curious about the mechanism by which starting ether breaks piston rings. I know that the obnoxious loud knocking sound of old mechanical injection diesel engines is caused by the unstable combustion propagation of the injected fuel. I know that modern electric injection diesel engines have...

    Birken Vogt said: "I disagree a little bit with that posting, also. Spinning the starter doesn't damage anything but the starter. If the engine pops and stutters it is helping the starter along at that point and starter time limits can be disregarded..." Maybe... The *only* insulation between...

    Transition from Plant mechanic to operator

    ethanu1, What everyone here said is correct. My advise, to you, is to motivate yourself, and push yourself, and take-a-new-job when you need to, to get yourself to where you want to be. Operator, mechanic, business owner, what ever it is that you want to be, it will only happen because of...

    Case 521D

    If it is over-cooled, that is the thermostat. A hyd fan that runs all of the time is the same as a belt driven fan.

    case 621 zf transmission issues cold weather

    The immersion heating element seems like a very good idea. Putting it in the oil sump is the problem, maybe even a new hole is necessary... The 621 *is* cold blooded, ours takes a long warm-up before it'll move in 1st or 2nd gear.

    Knepp said: "Used in good sense ether is just another tool. If something is spinning over and smoking a little I'm giving it a snort of ether before I drain the battery or smoke a starter. Im pretty sure a sniff of ether does far less damage then draining the batteries and taking life off the...

    numbfingers, The KarryKrimp 1 and 2 are outstanding machines. Making 'Tough Cover' hoses, to your exact fit, is worth the price of the machine. The Parker TC hose beats the snot out of the Eaton/Weatherhead or the Matchmate stuff... making the best hoses, on the spot, will sell your services...
