**For turning the engine over using the pinion gear nut** \\ 

|  You can use a 15/16" wrench or deep well socket to turn the engine over using the pinion gear nut. ((photos by Hippysmack))  ||

^  93-Present Pinion Gear Nut (7916A) ((photo by Hippysmack))  ^^

**To remove or install the pinion gear nut** \\ You'll need to lock the pinion gear from moving while turning the nut.
  * It's very important to hold the crank on the pinion side with an appropriate pinion locking tool whenever you take the pinion nut off or put it on.If you hold the crank still from the primary side (or by putting the bike in gear and holding the brake), the twisting torque applied to the pinion nut gets transmitted through the crank, from one side to the other. The crank pin is not designed to resist much twisting force. You'll risk scissoring the crankshaft (knocking the crank out of true), which requires a full tear-down to fix. ((Hammer Performance http://www.hammerperf.com/xlvalvetrain.shtml#grindlock)) So this is one of those situations where it's best to use the proper tool.

==== Origin of the Grindlock Tool ====
From XLFORUM member, "~Grind~" ((http://xlforum.net/forums/showthread.php?t=1448694)); \\
<blockquote> (I) broke a tooth off the pinion gear upon applying 70 ft./lbs. of torque to the pinion gear nut per the Zipper’s cam installation instructions. ((photos by ~Grind~ of the XLFORUM ((http://xlforum.net/forums/showthread.php?t=1448694))</blockquote>

<blockquote>I torqued the pinion gear to 70 ft. lbs. using a tool I made just for this purpose (below). \\ I had another friend of mine scribe "HAMMER PERFORMANCE" on it and then sent it to Hammer Dan as a token of my appreciation for all of his help. ((photos by ~Grind~ of the XLFORUM ((http://xlforum.net/forums/showthread.php?t=1448694)) </blockquote>

|  The Grindlock Pinion Shaft Locking Tool engages for the full depth of the pinion gear for max. strength. ((photos by Hippysmack)) \\ Due to a change in the pinion gear in 2000, there are 2 different versions of this tool: \\ 1. (91-99) year models & 2. (2000 to present) year models ((Hammer Performance http://www.hammerperf.com/xlvalvetrain.shtml#grindlock))  ||

===== Pinion Gear Runout =====
|Attach a scrap piece of metal to the outside of the gearcase and position a gauge holder on it so it won't move while turning over the engine. ((photos by anachris of the XLFORUM ))|||

|Install a dial gauge on the holder with the pointer on \\ the pinion shaft. Find the lowest spot while turning \\ the engine over and 'zero' the indicator.
