    Help With Aluminum Sulfate Mixture

    We have a home treatment system whereby we pump in pond water into two tanks where the water is treated by iodine, injected with an alum solution, then run thru sand and charcoal filter and finally thru a 1um final filter. The system works well and I have no complaints. To save myself driving...

    amphibious drive

    I knew a guy who played with WWII era Ducks (DUKWs) in the '50, '60s, and '70s, turning them into motor homes and taking them up to Alaska, sometimes by water up the sound. He made various mechanical mods over the years, from diesel engines, Allison automatic, conversion from 6x6 configuration...

    Drilling Torque Converter for Drain Plug

    Nope, I drilled and tapped a hardened steel plug almost identical to the factory type. The converter housing is 1/8 to 3/16 inch thick, so there was plenty of mean for threads Jim Allen Keeping the Good Old Days of Four-Wheeling Alive

    Drilling Torque Converter for Drain Plug

    Well, it's done. No discernible problems with balance revved to 5250. Used a single hardened 1/8 in plug with a copper gasket. Took 10 minutes. The worst part was the oil running down my arm while I tapped, though that washed all the chips out as well. Thanks, all, for the exercise of thought...

    Drilling Torque Converter for Drain Plug

    GMIRacing: IMO, the risk is fairly minimal if you, A- drill at a slow speed with depth control on the bit, B-drill with the converter full of oil so whatever does go in will be flushed out and C- tap with a well greased tap. I will admit, I had to calm my nerves the first time! As I said, I've...

    Drilling Torque Converter for Drain Plug

    My intention is to drill and tap a drain plug into a Ford 4R75E torque converter. Until just recently, they were drilled from the factory but they have since stopped. I intend to drill it in the same relative position of the OE converter through the very convenient bellhousing hole, which they...

    coolant formulation tech questions

    Another source of cavitation is localized boiling due to thin cylinder walls and insufficient coolant flow and/or system pressure. Combined with all the other factors noted above, the Navistar (Ford) 7.3L IDI (basically a bored 6.9L) suffered from this. With relatively thin bores, the problem...

    Terminology: Pilot Model vs Prototype

    Bill: I am those books, among others, and a couple of thousand magazine articles. One of these days, I'll actually become proficient! Jim Allen Keeping the Good Old Days of Four-Wheeling Alive

    Terminology: Pilot Model vs Prototype

    Bill: Freelance, fulltime for more than 15 years. For the past 4 ears, have also worked a (small) farm on the side for fun and (small) profit. Jim Allen Keeping the Good Old Days of Four-Wheeling Alive

    Terminology: Pilot Model vs Prototype

    Bill: When I worked for Land Rover (not in engineering), the term "Preprod" was often used as well. Mike, Greg: You mirror my current thoughts precisely, though I have often used the terms incorrectly to follow "convention." Thanks. Jim Allen Keeping the Good Old Days of Four-Wheeling Alive

    Terminology: Pilot Model vs Prototype

    A thread below on "mules vs prototypes" leads me to another question, one that we auto historians hotly debate. In the writing game, the terms, "Pilot Model" and "Prototype" are often interchanged. I think there would be distinct differences between the two but since we seem to have a fair...

    Replacing tires on all wheel drive vehicles

    I don't know if the Volvo you refer to uses a viscous coupling. If it does, you may want to be more attentive to the tire thing. Over the years, Jeep has had numerous problems with viscous couplings in the Quadra-Trac systems, many of them due to mismatched tires. With mismatched tires the...

    Calculate Tire Radius (or diameter) Changes Due to Speed

    FoMoCoMoFo: You are very likely correct. I have just unleashed my pedantic alter-ego on this. The numbers for the new, slightly taller tire, plugs in almost perfectly. Great handle, BTW!

    Calculate Tire Radius (or diameter) Changes Due to Speed

    Let me get to the meat first. We will be needing new tires soon and I plan to upgrade to a slightly taller 16 inch tire to correct a built-in speedo error (see below). I'm reviewing revs per mile on the existing tires as well as some taller alternatives. In order to make my calculations more...
