86-91 RX-7 Fighters MBK Install

1) Remove stock battery lid and surround if so equipped.

2) Loosen battery tie down and remove if so equipped.

3) Loosen battery terminals and disconnect them from the battery.

4) Remove stock battery and set aside.

5) Use a 10mm socket to remove the 4 mounting bolts for the stock battery tray. These bolts are usually rusty because water collects in the tray. Spray the bolts with a pentrating lubricant to ease removal.

6) You will be left with this picture. The mounting points used for the Fighters MBK are the two upper left ones from the previous picture. In this picture, they are the hole on the 90 degree stock bracket going over the oil cooler line and the other point is the left most hole.

7) Set the MBK tray on the frame rail and align the two holes with the stock mounting points. Spray the threads of your new stainless bolts with penetrating lubricant to ease install. Tighten the bolts gradually, going from one bolt back to the other until the mount is equally torqued between the two of them. This method will help to make sure that the bolts are torqued equally.

8) Slide battery into bracket. Feed heavyweight strap through the slit, under the mount, and around the top of the battery. Tighten strap. Connect battery terminals.
