 Before removing the primary cover, you'll need to remove the shift lever bracket (or mid foot pedal bracket if applicable), linkage and derby cover. \\

 You can punch the holes with a screwdriver, insert the screws for holding and it makes reassembly less of a headache. \\

+====== Installing the Cover ======
+Torque specs are in the FSM but torque sequence is not. In order to get the best seal and keep the cover from warping, it should be torqued in sequence. \\
+Torque spec is 80-100 in/lbs. Suggested torque sequence is in the pic below. \\
+**NOTE**: using too much torque on these bolts has been known to strip the bolt heads and crack primary covers. \\
+If you are using a clicker type torque wrench, it's best not to on these small torque values. \\
+Clicker type torque wrenches have a habit of giving false results. In that case, just use the "snug plus a nudge" method with the sequence in the pic below. \\
+Snug all the bolts in sequence first, then use the same pressure "nudge" on the second pass. \\
+As this method will not tighten all the bolts the same, you'll have to use "feel" to know when to stop. \\
+If you are using a beam type torque wrench, use the sequence below to get to the torque spec. \\
+This is a proven sequence that will pull all the bolts up evenly without distorting the cover. \\
