TENSION HEADACHES: A Harley Owner MUST SEE!

This video details the procedure for inspecting the timing chain tensioners. These tensioners are a maintenance item, but are often overlooked (even by dealership technicians) because there is no specified inspection schedule. Failure to maintain the tensioners can cause catastrophic engine failure.

Thank YOU for this video. It’s perfect and helps a LOT to understand how to deal with this issue. Cheers from Holland.
Excellent detail in the video! Thanks, man.
one of the best harley vids i’ve seen. I’ve got a pretty loud tapping coming from my engine (88 evo). I’m having a hard time pinpointing it’s location, but the more of these vids I see, the more confidence I have to open up the engine. So thanks and keep em coming.
@cap820 Thanks for watching.
Very informative. Thanks alot. Keep up the good work.
@grf0001 Good information. Thanks for posting.
The improvement in 06 was not necessarily the hydraulic means of pushing the pads on the chain but the fact that the chain is a roller chain and of course the gears were changed to match the contour of the roller chain. Once the outer links of the roller chain groove in and the chain starts to roll on the nylon pad they will last the life of the motor. Harley hide this fix in the smoke of stating hydraulic. Tensioners on roller chains can be hard rubber on Toyotas and last 200K
@opticschief I hope you’ve found it helpful.
Thanks for the video. Good info.
@2002nighttrain Gear drive will eliminate that problem, but may make a worse one. HD has an “acceptable” amount of crankshaft runout (basically that is the “unstraightness” of the crankshaft) if you have a bike with excessive runout on the crank you may have excessive noise with gears, or even gear, crank or bearing failure if the runout is really bad.
Something to look into before going with gears…
if you go to gear drive this problem must be elimenated for less money that the se up grade kit?
You state that the new SE tensioner system from ’08 doesn’t seem like “much of an improvement” well it is the next best thing to gear drive. Pressure against the chains from the tensioners is variable with rpm and oil pressure which significantly reduces the wear rate plus the tensioner material is more durable than what went before. I use this system with Andrews TW50 cams and it has performed very well for the past two years.
Hard to believe the MOCO ever considered putting crappy spring-loaded-nylon pads to tension a segmented silent chain. My ’63 Chevy Impala had a timing chain just like it and didn’t need a stupid adjuster and had over 100k on it. This is not the state-of-the-art engineering I would expect from an “elite” brand. This is “planned obsolesence” gone amuck. Why does the V-twin need 2 cams to do the same job of opening valves 1 cam has been doing for 75 years. S@S cycle gears can fix the problem.
Great video. Very informative. I believe I can do that. How do you disconnect the camshaft position sensor on a Dyna SG 2000 so it can be replaced?
My Son has a 2000 Road King with 50,000 miles He encouraged Me to watch this. I own a ’01 Electra Glide with 54,000 miles. My cam chain tensioners are worn and noisy. I took it to an independent shop and am upgrading to the Hydraulic set up, at a cost right at $1000 dollars. He will use SE adjustable push Rods. There are a lot of expensive tools used to pull the whole assembly out, and perhaps ways around that. My Son will try to replace the stock adjusters Himself. I opted to upgrade
@brokenspoon85 Thanks for the comment.
harley recommends you check the tensioners between 30000 and 40000 miles
@oliverpolland Your welcome. The inspection is fairly simple. Replacement…a bit more difficult. Let me know how it turns out.
Thanks for watching.
Thanks, Loud. You encouraged me to do it myself.
@L0udP1p35 To be honest I haven’t really researched them or looked too close. I’ve only ever glanced at them and drooled… There are so many sweet looking bikes. I guess I might like a Dyna Street Bob or on the opposite extreme an Electra Glide (full touring package). Can’t decide whether I’d want something old school or comfortable. Hehe…
@RC62 The scraper looked and sounded much worse than it actually was. There was a good seal on the gasket.
Just curious; Any particular model of HD peak your interest?
Although I don’t have a HD (it is on my bucket list), I found this to be quite interesting. Scared me a bit when you used the scaper to remove the cover. ;D
Great vid!
@Iroquois14 The quintessential motorcycle.
Harley Davidson everybody!
@maikeli7 Ultimately I was really pleased with mine. From what I’ve read, I was expecting much worse. I would be interested in what you find out. Do you know if your bike has the upgraded hydraulic tensioners?
