I am ordering my CCT's tomorrow, but had a question. the bike shop near me, said they can order the OEM ones. does it matter if I get the ACCT or the MCCT. Are the newer ones fixed?

nykuryu

the whole point to getting mccts is because the accts tend to fail rather suddenly usually ending in you needing a new engine. get the mccts and be set.

No, the newer ones are not "fixed". They have the same potential for failure as the old ones (other than age). Make sure the bike shop knows that if they install your manual CCT's wrong or if the auto ones fail there is catastrophic internal damage to the superhawk. This is unlike what they're probably used to on inline 4 bikes which the bike doesn't run well and makes funny noises.

I'd recommend printing out the "how to" instructions found on this forum and take them with you to the shop so they know the process.

i dont plan on taking it to the shop to fix it, they wanted 500 to put them in, i have a buddy of mine whos been working on bikes for a while now, we were going to change them ourselves.

Yeah, dont order stuff from a stealership unless you are stranded & have to.(unless you have unlimited cash to spend & dont mind getting ripped off) Go online & get the ape ccts.

And what happened when you tried to install MCCT's in your bike?

The only point I'm trying to make is follow all the instructions installing them and if you are not really comfortable with the adjusting procedure you might be better served installing a new set of auto tensioners.

Yes they should be changed out the choice of running auto or manual units is a personal choice.

nykuryu

hey hey hey....thats because i was a nugget and loosened them too far. and to add insult to injury i mistook the ticking sound for loose cam chain and kept adjusting and adjusting and i think it was just valve tap.......

eventually your gonna wanna replace the units anyway. you never gonna know something til you do it

sevenchaos

so is it easier to install the ACCT? my friend has been working on bikes for years and think he shouldnt have any problems, but if i did put in ACCT i should be okay. i dont know what i should do.

nykuryu

like i said, your acct should be replaced with a mcct eventually anyway. might aswell do it now. its peace of mind and cheap insurance for your motor.

ACCT= same installation process, no adjustment necessary
MCCT= adjustment necessary

You have to be somewhat careful installing both if you do it wrong, the cam chain could skip gears and cause timing problems. The major difference is that you have to adjust the tension manually in the MCCT, and possibly do this every couple of years or so. Adjusting takes very little time, but is also where the risk factor is.


With the auto, you don't have to worry about adjusting, but do have to worry about failure. This happens very rarely (and you don't hear about the ones that don't fail), but is is a very costly if it does happen

With the manual, you have to adjust it correctly, and sort of keep track (most people have run them for years without needing any adjustment), but once you do, they can't fail.

Well, "manual" is just the method of adjustment when installing. Don't think this is a regular maintenance item. In 30k miles I've adjusted them once, and only because I loosened them to fix a small oil leak on the rear one. I wouldn't expect any adjustment would be required at all to be honest...ever.

sevenchaos

yeah i am prolly going to end up getting the manual ones, i was just curious on since i am kind of new to the bike, getting the ACCT for now, and then in 15k or so change em out, if i still have the bike by then

sevenchaos

ordered the APE's today, gonna be here tomorrow, installing them 2 marrow

I am ordering new CCT's this week. Besides adjusting the manual CCT's... what is involved in actually installing them? Is it the same procedure as installing ACCT's? How difficult is it? I couldn't find anything in my shop manual as to how to install them. I know there is a How-To to adjust.

7moore7

Look at the link I posted up a little bit. It's a very thorough install How To. In fact, adjusting them is done in the install unless you are comfortable with the "twist out until you hear slight rattling, then go back in while the motor's running" method. If you have further questions, ask away...

996thehawk

Thanks for the quick response. Honestly, I know I am going to get some heat from most of you guys but I am most likely going to install new OEM CCT's. I know the manuals are recommended but I just want to go OEM. So, I am basically trying to figure out what is involved in installing new OEM ones.

superdutyd

Download the service manual that is on this site somewhere. At least i think it still is. It will have all the info you need.

7moore7

Not a problem with that as long as you know why you made the decision, and plan on doing it again after several thousand miles.

The install for OEM CCT's is easier because you don't have to set the tension.

996thehawk

I just read through it. Seems pretty self explanatory. I just feel more comfortable putting the OEM ones in and changing them out every so often, rather than adjusting the manual ones. I mean, my OEM ones lasted 21k miles so far.

7moore7

"Adjusting" manual ones is fairly simple and does not need to be done regularly- probably as often as you replace the OEM ones if that, just FYI. It's not like maintenance on your chain or anything...

VTR1000F

Mine lasted almost 21,000 miles before my Superhawk became a thumper. I think I've read of them letting go with a little more than 7,000 miles on them. Honestly, I think it has much less to do with mileage than age and random chance. Mileage, heat cycles, lack of oiling (for cooling), etc. may all play a part, but I feel it's age and an inferior spring at the bottom of it all.

So, when you buy a "new" OEM ACCT, how long has it been sitting on the shelf? Has the spring been under tension all that time? Does it matter? I dunno. All I know is I wouldn't even consider putting OEM ACCT's back in my bike.

BTW, the only reason 7moore7 thinks the manual conversion OEM's look better is because his are yellow. Can't argue with that. EDIT: Oops, that comment belongs in another thread.

I installed new manual tensioners last weekend. Removed the spark plugs and rear cam cover. Found rear top dead center ( verified by cam position and marks on cam gears). Zip tied the gears/ chain so it couldn't skip and very carefully released the bolts. Nothing moved installed new manual then removed the zips and rotated counter clock wise crank to front top dead center, removed old carefully and installed new manual no prob...no more living on borrowed time waiting for a cylinder to grenade

996thehawk

Do you guys think riding style has anything to do with ACCT failure?

VTR1000F

I don't.

I do think you should heed your signature.

It has everything to do with it...but what do I know..... Though I do have 96K on my bike, all with factory stock CCTs.... yes they have been changed out when needed but the bike still runs strong everyday.

996thehawk

I always thought that sudden closing of the throttle at high RPM's put a lot of stress on the CCT's and was most likely when they went, along with poor design, lack of oil, or cooling.

Holy mother! MIKE! What are you doing back here? I thought I opened up an old thread and was thinking "man, I remember reading this one like it was this morning" PWNT has need some TLC lately.
