    Oil pump for transfer case and diffs

    All,

    I've always used on of the cheap can-top pumps to fill my diffs and transfer case (and gearbox on the D2) but due to a bad case of acute lateral epicondylitis (tennis elbow) I am finding it harder and harder to pump the thing, not to mention being in pain for days afterwards.
    Does anyone know where I can get a small electric pump that would do the job without the manual effort? 12V or 120V would be fine.

    Thanks,

    Graeme

    Man, I'm so .... why didn't I think of that? Great idea, and cheaper than any electric pump. Thanks.

    I owe you a beer ... maybe a case of beer ....

    Went to Home Depot. Bought the $8 and change 1 gallon sprayer (was going to buy two, but though I'd check it first). Removed the nozzle and connector (leaving the solid fiberglass-looking end pipe). Filled it with gear oil, gave half a dozen pumps and was all set.

    Drained the rear diff, poked the sprayer in the hole and clicked the lever to the 'on' position. Filling is slow, but totally effortless! I sat and watched the level slowly creep down. I should have gone for coffee. I pumped a few times half way (but from outside the vehicle in total comfort) and was done in about 20 minutes. I think I'll replace the solid tube with a flexible one with a larger bore, but that is 'fine tuning'.

    I can't believe that I struggled for so long. I actually like changing the diff oil now.

    The best tool I have and under $10. Nearly as much fun as my air powered grease gun (and I though $20 at HF for that was good).


    Thanks again.

    You might also want to check out the deck sprayers. Same basic design but they are designed to spray a heavier liquid(deck stain vs. pesticide). They are a bit more money though($20-ish) but will accomplish the oil refresh in a bit less time.
