Abstract
A method of removing a sensing rod from a hydraulic water pump includes an access plug, a sealing o-ring, and an end block modified to receive the access plug. The access plug preferably includes a front flange, a threaded body, and a rear tapered end. An o-ring groove is formed adjacent the front flange to retain the sealing o-ring. An internal thread is preferably formed in the modified end block to threadably receive the access plug. An opening is formed through the length of the access plug which is sized to receive the sensing rod. The access plug is unthreaded to allow the sensing rod to be removed. A nut removal tool inserted through the internal threads of the modified end block to unscrew a rod nut. Once the rod nut has been unscrewed, the sensing rod may be removed.
