It is almost like they want to discourage you from changing the engine oil on 650HD!

  • It is almost like they want to discourage you from changing the engine oil on 650HD!

    Before I start complaining, let me say that I really like my 650HD. The number one thing I like about my machine is the Adair Tracks. The number two thing is the Admiral Transmission. I purchased the 650HD to perform topographical surveys for agricultural purposes, mainly land leveling field designs in field conditions too soft for my Toyota Tacoma 4x4.

    It took me an entire day to perform the first service on my 650HD. Granted, most of the day was spent running back and forth to purchase items specific to the obstacles presented in servicing this machine.

    While trying to decide how to drain the engine oil without making an absolute mess, I went ahead and changed the oil filter. Then I realized that the oil filter even further blocks access to the drain plug, so I took the oil filter back off. I then made one of my many trips to town to purchase a vacuum pump to pull most of the oil out through the dipstick tube. After discovering that the tube that came with the vacuum pump was too big, I made another trip to town to purchase various sizes of tubing and reducers. My idea was to suck most of the oil out and therefore limit the possible mess when removing the engine drain plug.

    After not having any luck using the 8 point 7/16" square socket that the Argo manual mentions, I found that an 8 point 1/2" socket would fit the drain plug. After locating a small piece of pipe that would fit over the ratchet for leverage, I removed the drain plug. I held a plastic bag up under the drain plug to catch most of the oil that was left in the engine.

    Am I missing something? How do you change your engine oil? What specific tools are you using? Please include model numbers, if available, for tools, vacuum pumps, etc.

    I just use a cheep little shop vac, dedicated to "oily work". Pull the drain plug and let the vac suck the oil up as it drains out.
    Other guys just use the "Zip-Lock" bag thing. Pull the plug and let the oil drain into the bag, zip it up, and remove/dispose of.

    Replacing the stock square head plug with a standard hex head plug is cheeper than buying "special" sockets. Another option is a "Hex Key" plug.

      Use a gas can and shop vac. Insert a 1/4" tube into the vent on a plastic gas can (drill it for a snug fit) long enough to reach down into the dip stick on the engine. Attach the shop vac to the fill port with a rubber coupling. Once you push the 1/4" tube all the way to the bottom of the crank case turn on the shop vac and drink cold one while it sucks it out. No, no oil will go into the vac, just the gas can. There is no need to remove your drain plug. This will remove all the oil with zero mess.

        !!! BE SURE THERE IS NO GAS OR RESIDUAL VAPOR!!! It CAN be ignited by a shop vac.
        Yes, I have seen the Mythbusters episode too. But I have also seen the photos from my Boat Insurance Company, BOAT U.S., of cases where while vacuuming out the bilge an owner intentionally or unintentionally sucked up gas or vapor. Some of these instances WERE FATAL! I'd personally recommend a gallon milk jug, or gallon/5quart oil jug or other non gasoline container, unless you use a new gas can that's never had gas in it.

          The vacuum system is the way to go. No mess and the oil is changed. Put some rags under where the oil filter is to be removed and that should take care of it.
          Life should not be a journey to the grave with the intention of arriving safely in an attractive and well-preserved body, but rather to skid in sideways , cigar in one hand, whiskey in the other, body thoroughly used up, totally worn out and screaming "WOO-HOO, what a ride!!!"

            A milk jug will just collapse. I've been using this method for 20 + years with no earth shattering kabooms. The gas can is obviously dedicated for oil.

              I just wanted to be sure no-one empties a can of gas, and tries this. While more than likely nothing will happen, if it does, it's bad
