Cam Chain Adjuster

[Nick7777]

any of the r1 or r6 cct ever work by chance

Theres a full list of ACCT that fit here.

I just got one last week that was off a 2001 Raptor for $9, express shipping included.

thanks a lot man. just turned the bike over and noticed that wasn't there, my first bike and i have to put it together as well. im guessing its out of time now....

[Tat2demon]

You don't have a tensioner at all? If it hasn't skipped some teeth and taken out your valves Id be surprised.

[Nick7777]

correct, i turned it over, no gas in it so it didn't fire, just wanted to ensure the motor wasn't seised up.

What Nate's sayin is, if there is no tensioner in the engine then there is a very high probability (~99.9999%) that you wrecked some valves, even if it didnt fire... no tension on cam chain = no cam rotation = valve to piston contact = bent valves. I think you may have a big problem on your hands...

Did you take the tensioner out of the engine? Do you know where is is located or know what is looks like? Im not being rude just dont want to build anxiety or send you on a wild goose chase because you dont know what/where the tensioner is...

In order to see if you have any bent valves your going to have to reset the cam/crank timing. First, do not rotate the engine anymore until you do the following. Take the valve cover off, loosen all the cam journal caps and remove the cams so all of the valves are unloaded, turn the engine with a wrench to set the crank to the "C" mark under the left cover (remember to turn clockwise as imprinted on the little wheel). Reinstall the cams (I suggest following the manual on torque sequence) and install a cam tensioner! Then check compression and report back here.

I suppose you could check the alignment dots on the cams to see if they line up but if there truly is no tensioner in the motor when you turned it over then there is no value in checking this... Good Luck!

You might want to spend some time on here reading and searching for tips especially when it comes to engine work or you could get in over your head real quick. All the mistakes have already been made and documented on here.

Exactly, Raptor CCTs are plentiful and cheap, why re-invent the wheel? Just bought 2 and installed for around 20.0

WMARSHY, I usually work on cars, and no i did not remove the CCT(last thing i would have looked for since it had pipes and everything already installed). I had bought the bike about two months ago and the PO said that a bike shop in his town had went through the motor and did a couple thousand dollars worth of work... some mechanics if they can't put somthing as simple as this on. thanks for the advice and i'll let you guys know if i screwed the pooch or not.

Wow, some mechanic! If you get in a bind or have questions dont hesitate to ask. Try a quick search first, you'll be amazed how many hits you'll get that suits your exact question/problem. And ifyour your looking for replacement valves, I know one member has a full set left from having some aftermarket ones made... I think he's only willing to sell the entire set not individually.

If a new cam chain was in that couple thousand dollars work, you're probably in luck. I just changed mine and it was pretty tight. So, if your chain is new it may not have fallen off the crank sprocket. If the chain isn't new, I concur. The crank rotated and not the cams.

Interesting ... it might be worth check the alignment dots on the cam to the C mark on the crank timing plate then before you go taking the cams out then. You have to remove the cam cover still.... no biggie.

The dots line up when on the T mark.

and i have read some talk about cleaning the excess material off the pin so that it matches the stock length, is there a set dimension for the 81 motor, i read somwhere that the cams are different over the model years and would hate to shoot myself in the foot even further than i may have already.

[natemoen]

Don't take anything of the plunger, you get more length with the acct's thus longer between chain changes.

[Nick7777]

oh, thanks for the advice. and now just to wait for the mail man to bring it. any altering of the raptor acct needed.
