FER CRYIN' OUT LOUD, STOP TELLING PEOPLE THAT THEY NEED TO LINE UP CAM AND CRANKSHAFT POINTS WHEN THEY ARE ONLY CHANGING THE TIMING BELT!
If you are just changing the belt, it is NOT necessary to line things up as they are ALREADY lined up. The ONLY time you need to line up the crankshaft and camshaft is when you do something that causes either the camshaft or crankshaft to rotate independently. Examples are a broken timing belt, removing the head, removing the crankshaft or any other activity that requires turning either the crankshaft or the camshaft independently of each other!
Naturally, if your engine is running poorly and it is because the timing belt was installed with improperly-aligned crank and camshafts, you can fix that by using the marks and the procedure found in the Samurai Factory Service Manual - which can be downloaded for free at Ack's FAQ (see link in signature).
Also, DO NOT TOUCH THE BIG BOLT ON THE END OF THE CRANKSHAFT! This bolt has nothing to do with removing the timing belt cover. You can remove the acessory pulley on the crankshaft by removing the four (five on a TracKick) smaller bolts that attach the accessory pulley to the crankshaft timing pulley. Again, this is illustrated in the Samurai Factory Service manual and also applies to the TracKick.
...and yes, it is a very good idea to disconnect the battery. That way you won't accidently turn over the engine with the timing belt removed.
