1. Have one -- used it several times -- always works.
2. Screw axle nut "reversed" on axle shaft, to where back of nut is flush with outward end of axle threads to protect both axle threads & nut threads.
3. Exercise patience & carefully turn the two (2) large bolts often & turn very little after every series of 3 or 4 light hammer taps.
4. Use a light ball pein hammer hitting with multiple light taps as opposed to a 100 lb. maul with one monstrous, gorilla lick making the vehicle fall off of the jack.
5. Exercise care in tightening the 2 large bolts to mantain the outward, black part of puller, (with center hitting lug), parallel to the outward face of the wheel hub.
6. Make a small wooden box container with hinges & latch, and be sure to include a copy of the installation instructions within -- then put a few "Axle Hub Gaskets" in the box, part no. A-4244, (Bratton's part #6230, plus 1 or 2 rear axle key(s) & 1 or 2 axle nut cotter pins.
7. Don't leave home without it -- especially on a long trip alone or with other Model A's -- no mechanic shop along the highway will have this handy tool.
