When the separators are all in place, even them up on each side. Then tighten the sealing nuts with the special Exide wrench. When you have turned the nuts down tight, lock them in place by driving a center punch on the threads on the post just above the nut, Fig. 241. This will damage the thread and prevent the nut from turning loose.
Putting Plates In Jars
The next step is to lower the plates into the jars, as described on page 362. In types KXD, LXRE, and XE be sure to first replace the two soft rubber buffers in the bottom of the jar, one over each ridge.
Filling Jars With Electrolyte
As soon as you have an element in place in the jar, fill the jar with electrolyte of the proper strength, as described on page 364, to prevent the separators and plates from drying. The negatives, especially, must be covered with electrolyte to prevent them from heating and drying.
Sealing Exide Battery Covers
For Types DX, LX, LXR, LXRV, PHC, XC, XX, and XXV, which have the single flange type of cover, slowly heat the sealing compound until it runs, but do not get it so thin that it will run down into the cell between the cover and jar. Then pour it into the channel between cover and jar walls. Allow it to cool and finish it off flush with a hot knife. When pouring, be sure the compound is liquid and not lumpy, as in such a case a poor seal will result. A glossy, finished appearance may be given to the compound by passing a flame over it after the job is finished.
For Types KXD, KZ, LXRE, MHA, and XE, which have the double flange type of cover, have ready a string or worm of sealing compound about 3-16 inch in diameter, made by rolling between boards some of the special compound furnished for the purpose. The cover may or may not have been attached to the element, depending on how repairs have been made. In either case the procedure is the same as far as sealing is concerned. Assuming the element is attached, stand it upside down, with the cover resting upon two strips, Fig. 242. Lay the string of compound all around the cover channel. Now turn right side up and insert in the jar, taking care that the jar walls enter the cover channels at all points. Apply heat carefully to the edges of the cover and gently force cover clown. If too much compound has been used, so that it squeezes out around the cover, scrape off the excess with a hot knife while forcing cover down.
