Gates has a great Timing Belt Replacement Guide on their website that you can download. It tells you what engines have belts, if they are interference or not, and the recommended replacement interval. Go to www.gates.com and click on the Timing Belts link.
but my engine doesn't have a timing belt. also they may not break but the explorer has nylon tensioners that i'm sure wear out. i've had v8's that were interference and when the chain broke i had to replace valves. i just had the heads off to put on new head gaskets and do not want to take them off again that's why i was thinking of replacing the chain, in case it breaks. if it's not interference i'll still replace it just not as soon as i was thinking.
honestly I wouldnt even touch the timing chain unless your doing a full blown rebuild, do a quick search on ohv timing chains. You wont find many issues, the much more common fix for internals is replacing the worn pushrods.
I'd have to agree.. In the past 10+ years being on EF (wow, its been a long time) I can't remember seeing anyone that needed to change the timing set on an OHV.
I replaced/rebuilt our motor at 355k miles.. nothing in the timing chain area looked overly worn. I didn't replace the timing chain set becuase I rebuilt my spare motor which had 150k or so miles (in that range).. I didn't change the timing set on that one either as it showed very little wear.
