Replace Cam Chain Tensioner
Posted: Tue Nov 07, 2017 1:37 am
I need to change out my cam chain tensioner on my 2013 PCX 150. Does anyone have any instructions or a guide to accessing the cam chain tensioner?

Check your oil level, mine was too high and I suspect that it's the reason that the chain tensioner broke.

Fair enough if you think that was the reason in your case. Although I’m not sure you know the providence/history of the engine you are basing your opinion on. Did you know anything else about it other than it had too much oil and the tensioner was broken?Gil wrote:I bought the scoot with a bad engine sound, after diagnosing the issue. My friend and I noticed that the oil level was too high, it had a fresh oil change when the tensioner broke. The engine had ~3/4 of a quart too much oil. My theory is that as the timing chain becomes more submerged in oil, it adds more stress to the chain tensioner, leading to its failure. All I have for my theory is the fresh excessive oil and broken chain tensioner.

And a fine organized How-to it is!kiapolo1887 wrote:Replaced the cam chain tensioner this morning. Start to finish took about an hour-and-a-half. First time taking off any body panels or the luggage box, so the going was relatively slow. Did not need to completely remove the throttle body, just disconnect from the intake pipe and move out of the way.
Thank you for all your help!
I'll make a post in "How-to" if anyone is interested.
