Show uvj PUMP LEADING When the water pump begins leak ing, do not assume that necessarilyl it is because the nut is too lose. Frequently Fre-quently the nut is not to blame at all, but poor packing is the real cause of the trouble. Packing for this part consists con-sists of candle wick soaked in tallow, tal-low, heavy twine similarly treated or special packing material. After the nut has been turned to press the packing down, do not turn it further, as excessive squeezing is apt to damage dam-age some part of the body of the bump. |
