Often, pump maintenance and repairs are done out in the field with no access to shop tools. One of the most common maintenance tasks is replacing the shaft sleeve. Did you know there’s an easy way to remove the shaft sleeve, using only two hammers? This method works so well that it is often preferred over shaft sleeve pullers and other methods inside the Cornell shop!
Keeping one hammer steady on the shaft sleeve, strike the opposite side of the sleeve with the other hammer. Do this along the length of the sleeve, until the sleeve metal is stretched enough to be pulled off by hand. Watch the video to see how quickly and easily this method works!
