[QUOTE="longnokr, post: 400441, member: 1636"] I didn't have to make any adjustments either, they were all fine. I just replaced the tensioner for preventative maintenance. I pulled it out and put the new one in without moving anything. Evidently the slack drooped under the crank sprocket and grabed the next tooth when I installed the new one. I turned it over by hand but didn't re-check marks cuz most automotive chains I've delt with won't move without sprockets being removed. But, all's well and a good lesson learned. I don't see how it would be possible to [I]safely[/I] change the tensioner [U]only[/U] without pulling the valve and timing covers to verify the marks are on. dcarver-It won't be an issue if you have the covers off as you will to check your valves, just be sure and check the marks after you replace the tenssioner...if you do!
