    Raptor 660 ACCT

    Picked up an ACCT on Ebay from a Raptor 660 and installed it following the tech write up, pretty straight forward, and verified that the dots on the cams are where they belong when the timing marks are lined up per the tip. I do have a couple of questions though.

    1. The top bolt was a little tight going back in,couldn't do it with just my fingers. Not having a small round file to ream out the hole, I just carefully tightened each bolt a half turn at a time until they were seated, also putting on a small lock washer to make sure the bolt didn't bottom out. Do you think this is OK or is there a chance that something may develop a crack because of the extra minor stress??

    2. Looking at the oem tensioner, if you draw an imaginary line through the middle of both bolt holes, that line runs right down the middle of the plunger and the plunger pushes squarely against the center of the chain guide. That same imaginary line through the bolt holes of the Raptor tensioner does NOT run through the middle of the plunger, the plunger is offset towards #2 cylinder and only about half of the plunger makes contact with the chain guide. Will the Raptor plunger not pushing squarely against the chain guide cause problems? Anyone else notice this with any of the ACCTs you've installed? Does anyone have some serious trouble free miles on a Raptor unit? I sure don't want to end up wrecking stuff after installing an ACCT to avoid wrecking stuff

    Thanks for the knowledge.

    I didn't have a reamer or a file but the thin grinding bit that came with my Dremel worked just fine.

    Strange. The stock CCT on my 78E was offset exactly like the Raptor ACCT I bought.

      I just put a Raptor 660 ACCT on mine and had no problems and the alignment looked fine to me screws went in fine.

      I have questions did you turn it to the C position before removing the old adjuster?

      Did you have the bike level when you installed it?

      Did you do any rotation or movement while the tensioner was out or loose?

      Did it line up correctly with old tensioner?

      If all this was done properly then you have a much different situation than I did and I do not know why its so different.
      To fix the problem one should not make more assumptions than the minimum needed.

        Does the XJ run the same tensioner as the XS? I ask because every picture I can find shows the offset. Not a straight line like you say yours has.

            Here is a pic of the Raptor 700 ACCT I just got off eBay.. The offset is pretty large and it appears that when you flip it to make it fit, only about 1/3 of the plunger is sitting on the tensoner in the engine..

            I'm not gonna risk it. Gonna order another style.



            Here is the error I see with the raptor unit..

            1) Fire up Internet Explorer
            2) http://www.yahoo.com
            3) type "www.mapquest.com" into the Yahoo search page.
            4) go about day as VP managing multi-million dollar financial contracts.

              I'd get another one. That doesn't look or sound right to me.

                That was my exact concern Diskman, your photos illustrate the problem quite clearly. If the Raptor plunger doesn't push squarely on the chain guide I was afraid we'd be asking for trouble. Better safe than sorry, sure don't want to take a risk with the valve train!

                  Put it in the hole and look down the cam chain tunnel. Might be surprised.

                    Nate, when I pulled the stock tensioner out and looked into the hole at the chain guide, the guide was off towards the left side of the hole. It seems pretty firmly in place and didn't move much when I tried to push it towards the middle of the hole. The plunger on the Raptor unit is offset towards the right side of the hole when installed and just doesn't make good square contact with the guide like the stock plunger does. I did some research on my local dealer's web site and the part #s are different for the Venture/Vmax, Raptor, and Vision parts so I'd think there is some sort of difference in design. I'm far from an expert but the whole thing just didn't seem quite right to me. My apologies to anyone feeling like we're beating a dead horse here but I hate the thought of spending $10 on something that would result in the very thing I was trying to avoid

                      What you see in the hole is not actually the chain guide but is a flat metal blade that spreads the tension along the front leg of the chain guide. If your automatic tensioner is a bit off center on this it should not be of that great a concern.

                        I've been running with a raptor chain mod ever since I figured out you could use one. Best $5 I ever spent.

                            Nate, that plunger hits the tensioner bar even better than the Venture acct... which seem to have become like hen's teeth and more expensive.
