can u guess ? Twin Cam Harley Davidson Noise

[@timbarnett3898]

I can guess. First choice: seeing it's an 03' twin cam 88, timing chain tensioner pad wear on timing chain. Second choice: lifter/bearing wear causing wear on cam face. I'd be looking at cam chain tensioner pad replacement sooner than later. Destroy motor by oil pump sending metal throughout motor! I'm going with new hydraulic plate an hydraulic cam tensioner pad replacement. Kit comes with new 40% volumn oil pump. Expense keeps me from going with gear replacement kit, eliminating pad tensioners! Then I'd measure proper specs an adjust primary chain tensioner!

[@jimscycleandautotn8508]

Run hydraulic tensioner in primary , thank me later

[@yogi2.057]

The nylon cam chain tensioners are probably worn out and the values are slapping a bit. Otherwise, it sounds like the normal H-D chatter before a ceremonial rebuild. Nothing that a couple of grand can't cure.

[@patrickhollis5332]

Yea always a almost grand r more anytime u touch one it’s crazy

[@martinwall7297]

after 118 years, in mfg motorcycles, you would think the co. would have it all together, instead of having all our money!

[@patrickhollis5332]

Yep especially as much as one cost new

[@jerrychircop7121]

Primary tensioner worn out. Do a dial runout test on the crank and drop a gear drive kit from S&S if your runout is less that .005”. I would recommend an S&S 509 set of cams to bump up the torque on your bike, I really like them on my 05. Electra glide TC

[@johnfatboys]

thanks!!

[@johnfatboys]

well, it was! had a 7 year extended warranty when I got the bike in late 02. funny your comment about how I need to keep eye on it. I am starting to hear that howl again :(

[@MrMikeb8]

so it was an 88

[@BigEasy1967]

I can tell lot of folks aint no mechanical technician,cam chain tensioner will be the correct answer

[@johnfatboys]

It was cam tensioners yea. I was lucky that I was still under warranty. My 7th year I had extended. I also replaced my cams with a higher lift at the same time so it all worked out pretty good (:

[@MrMikeb8]

did you get to look at them after they pulled them out?[tensioners]

[@johnfatboys]

I have a feeling now with having 80 000 km on my bike that it may be coming back, starting to hear the howling when its hot after a long ride.

[@ДанилЗелезнев]

Hello! You solved the problem, where is the sound from?

[@MrMikeb8]

i have 140 000 km on my 2007 road glide. only had it for the last 3 years. primary tensionary worn more than half way down. havn't pulled cam the plate ,oil pump and secondary tensioner off yet.

[@scottliegel855]

sounded like your primary chain was just slapping the inside of the cover.. but you were moving the camera so many times it's kind of hard to tell from a video..

[@-MrRichBiker1967]

YUP...THEY ALL SOUND LIKE THAT!! mine is a 2005 tc88 b motor. 1550, 95"ssoooooo much valve train noise, it drives me nuts!!going to trade up, as soon as I get my new clutch pack, starter and compensater installed!! ( 2005 15 anniv fatboy 19,000 miles) I'm done!!!!going with the 103-non twin cam!! quite as a mouse, all you hear are the pipes!!

[@Mateo_1986]

where was the sound predominately at? Near the top of the head or down low in the block. I have a similar sound now and its in the front left of the head

[@frederickking1660]

Pull the cam chest cover and look at the cam tensioner shoes.

[@johnfatboys]

I Have 93000 k on my bike now. Can start to hear the whirring noise and I faint knock again. We see how next season goose.

[@kennethwise7108]

Please don't take this the wrong way but i don't know why people buy aftermarket cases like Delkron ones? Are the stock OEM HD cases junk? I've owned 3 Evo's over the years and never had a case failure.

[@MrMikeb8]

i heard the early evos were weak[ porosity] in their crank casings.

[@arthurcutaiar9994]

You said the magic word. Evo. Add gas n go. Twinkie, make sure your phone is charged. I wanna trade my 2003 dyna on a evo bike. Like saddle tramp did.

[@kennethwise7108]

@@arthurcutaiar9994 smart move

[@johnfatboys]

top, just like you hear, tried to move my camera around to get a different prospective of sound, not sure that worked too well.:) get it fixed! just gets worse.

[@John-ob7dh]

I think my 2002 fat boy is solid crank .?

[@dougfisher1885]

Sounds like tensioner and or cam bearing issues

[@johnfatboys]

that should about right, make sure they flush the fluid good

[@hondav65sabre]

you could get your crank shaft re trued..get your crank pin welded..or get a better helmet so you don't hear it..ear plugs are way cheaper

[@chib9427]

Bad.. LOL

Yep the best and cheapest r put speakers and radio r something if u don’t have one and turn her up

well i just did scramin eagle oil pump kit..still gotta rattle like noise...comes ans gos..almost likeyour in the wrong gear slow down and it lugs...like a fuel knock..any ideas....its mechanical..its down around the oil filter,,,comes and gos

[@buckotte1414]

Cam chains, tensioners....

[@johnfatboys]

tensioners and they did bearings too, plus I upgraded cam ;)

[@MxRyder19]

John Roussetos how mutch plz!!??

[@Ginnys73]

ahhhhhhhhh the Sound of that...Woooohooooooooooo

[@kennethwise7108]

Just sell it and buy an Evo, problem solved...

[@MrChopemup]

Kenneth Wise . Yeah right . I got about 300,000 miles on my delkron evo . Two top end rebuilds and it still runs smooth , I might split the case finally after 18 years .only to balance the crank again and some bearings . For the hell off it . Eh maybe next year ....lol...i laugh at twin cams . I have same horsepower than a 103 and no bs fixing it every year . Dont know why these fools buy these twinkies ...

[@bernardlandymore6772]

Harsh but true.

[@chuckmccroskey4864]

I’ll admit that I bought a 2009 ULTRA Twinkie. It handles great and all but the true Love of my Life is a 1991 FLHS. Bought it new 3/27/91, 10:00 a.m. at Colboch HD in Tennessee. I have 150,000 miles on her now. Did a reman at 120,000. The rocker boxes were never off of the ‘91. Never leaked oil till 105,000. My brother got hit in the rear on it last year and we’re rebuilding now. If I had to sell the ‘09 to fix it- in a New York minute! EVO Forever, Forever EVO!

[@patrickhollis5332]

Yea the ole EVO might not be a powerhouse but damn they’ll run forever just about replace wheel bearings 25 times before touch the EVO

Sounds pretty normal to me.

sounds like bad bearings or tensioners

was it cam chain tensioners or bearings?

[@zr6966]

Compensator nut...

[@tomcata1467]

FATALLY FLAWED DESIGNED TWINKIE, is all. Notorious for crankshaft twisting out of true, at the pinion shaft and "wobbling out of spec, which should be no more than 0.001" or less of shaft run out, as it progressively worsens, due to fact that it doesn't have a crank pin bolt and nut to hold both halves of the crankshaft together, like the single cam Harleys of old had, nothing is holding the two halves together. Nothing, as the flywheel was simply pressed together at the factory. When the shaft wobble hits, -0.003", damage to all the engine bearings, bushings, cam support plate bushings and bearings, cam bearings, all begins, and it progressively will worsen until the engine is cratered. Only solution for that is to tear engine down and take the flywheel to a performance specialty shop and have it taken apart and to re-hone the connecting rods, balance the flywheel components, reassemble it and have it dynamically trued and back to spec, and TIG-weld both halves together for a bullet-proof flywheel. Noise, could also be that the PLASITC silent chain drive tensioners either one or both have broken into pieces inside the engine and now you have METAL TO METAL contact between the tension holder and the METAL silent chain and is producing metal shavings which are being inducted by the oil pump into the crankcase and cylinders and will crater the engine and cause it to seize up and you are out one TC engine. Could be a bad compensator and rotor too that has been wallowed out inside the primary side housing. It's a TWIN CAM and these are junk engines. Harley used to use METAL GEAR DRIVES to operate the single cam engine and oil pump, but, starting in 1999 to the present, they went to silent chain drives with PLASTIC components in critical engine components. The rockers can also get wallowed out and make them elliptical and ruin the bushings. Also the silent chain can stretch and severely affect valve/cam timing, Lots of GREMLINS IN TC ENGINES.

[@stanfordpittman1654]

Yea, i agree in most part with what you say, they could of and should of done better in design of TC, but it is what it is. But it has a place it can go (a engine rehab so to speak) where when it comes back out and hits the streets... it will earn some respect from those who disrespected its potential abilities as being a solid bullet proof powerhouse. Now that being said, i still agree with all you say being that it is true, and if your a ride only enthusiast or inexperienced at engine building....than it is a fact and not the best choice of engine to have on your bike. On the other hand if you are a builder and have knowledge, experience, machining equipment and a pile of cash....you can make a TC shine beyond what one would expect it could do. I love EVO's but you can't get the same high RPM range a built TC can and it be stable doing so due to cam flex. The problem with TC's (Twin Cam) is that the engine is full of Harley parts....ditch them, all of them and don't go and buy screaming eagle parts either, they won't cut it if you want big reliable power. Now as far as the engine cases, of the TC...use them, they will be fine, i never have had one fail on its own, only fails were as a direct result of a component failure causing damage to cases. If possible try to get cases from a 1999 through 2002 TC because they came with Timken bearings from the factory. 2003 and up till the end of the twin cam production used straight roller bearings on crankshaft,

[@davidchereneimmel8820]

"Nothing holding them together", "simply put together".... ya only pressed under 50 tons of pressure. Hardly anything at all.

[@dannyanderson5348]

Trash cam chain and install gear drive, did that on my 1999 road king,
